Abstract: 

Objective: Fasciola infestation in breeding animals and studying of effective factors in parasite epidemiology in Kermanshah. Project: Field - laboratory study. Procedure: To study fasciolosis epidemiology in Kermanshah province, the following factors were studied: A- Climatic conditions: Climatic indices such as average raining, average monthly and annual temperature and humidity were obtained from Iranian Meteorological Organization. Based on meteorological data, this province, microclimatically, is divided into 1) warm plains (Gilane- Gharb, Sar-e-Pol-e-Zahab, ...), 2) temperate plains (Kangavar, Sahneh and Songhor), 3) mountainous (Kermanshah and Islam Abad) and 4) cold mountainous (Uramanat). B-Existence of intermediate hosts snails: sampling was done on some of the province water sources at least once a season. Identification of intermediate host snails was done based on their specifications. C- Infestation conditions in breeding animals (sheep, goats and cattle) : stool samples were taken randomly and examined by flotation method. D- Infestation conditions in slaughterhouses: Infestation situation of the animals, slaughtered in the province, to fasciola, was examined within a year. Results: On sampling from different ponds in the province Lymnea truncatula (intermediate host of Fasciola hepatica) and L. gedrosiana and L.auricularia (intermediate host of Fasiola gicantica) were found. But the prevalence of intermediated host is different in various regions. Random sampling was done in breeding sheep, goats and cattle. Areas I and 11 were the most infested and area IV was the least one. Based on the slaughterhouse datas, the highest and lowest rate of infestation were seen in area 1 and Paveh and Javanrood (area 4), respectively. Conclusion: Due to the difference of the provice height and microclimatological datas, infestation rate to fasciola is defferent in various regions. Area I and 2 are appropriate zones for fascioliosis to occur and area 4 is an inappropriate zone.

Abstract: 

Objective: To determine of a proper time to de-epithelialization of ileal segment by using collagenase and trypsin cocktail for ileocystoplasty. Design: Descriptive experimental study. Animals: Fifteen adult female mixed Persian dogs. Procedure: Ileocystoplasty was performed on 15 female Persian mixed breed dogs ranging from 2 to 3 years old and 15 to 24 kg body weight. Twenty centimeters of ileal segment with its adequate mesentery was selected. Five millimeters of ileal segment was taken for normal histological study of the intestine. Enzymatic treatment of ileal segment using 0.125% collagenase and trypsin cocktail in 5, 10, 15, 20 and 25 minutes was performed on dogs. After each enzymatic exposure, tissue samples (5 mm) were taken for histopathologic evaluation. Results: Microscopical study of 180 histologic sections showed that 5 minutes treatment (MT), focally denuded 20% of villi epithelium; while 10 MT has caused 33% of villi epithelium focally. In 15 MT approximately 60% of villi were de-epithelialized while 20 MT caused 75% villi de-nudation with more cryptlysis. Complete de-nudation of villi epithelium occurred with 25 MT. Clinical implications: The results of this preliminary study state reveal that approximately 25 minutes enzymatic treatment of ileal segment can completely de-epithelialize villi, and is recommended for ileocystoplasty.

Abstract: 

Objective: Study of the histogenesis of skill in sheep and detennine the relation between developmental stages of fetuses and histological changes of their skin. Design: Developmental investigation on the skin in sheep at the different stages of antenatal growth. Animals: A total of 75 apparently healty embryoes were collected from Urmia abatoir. Procedure: Immediately after slaughter H&E of sheep, the embryoes were taken out and their C.R lengths measured. The skill specimens were taken from face, neck, sholder, and forelimb of the fetuses. The specimens were fixed in 10% formaldehyde solution and processed through routine paraffin embedding, cut at 5-7µ and staind with H&E, Van Giesson, and Verhoof methods, for study fibroblasts, collagen, and elastic fibers respectively. Results: This study revealed that in second half of second month of antenatal life the epidermis consisted of 1-2 cuboidal epithelial cells, whereas at 61 -65 days fetuses, it was made up of stratified squamous or cuboidal type of epithelium. The melanin contaning cells were seen at the end of this stage. During this period clusters of epidermal cells accumulation were seen at epidennis, and more likely here were primordial hair follicles which were growing from epidennis towards the dermis. Mesenchymal cells were gathering around this structures. At the first half of third momth the collagen, elastic and reticular fibers, fibroblasts and leukocytes were appeared between mesenchymal cells. At the second half of third month the epidermis was apparently stratified squamous with the same degrees of cornifications. At first half of fourth month, an increase in thickness of epidermis was observed and at this time the hair follicles were in the form of inverted cup. The sebaceous and sweat glands were in bud froms around the hair follicles at 90-95 and 115- 120 days respectively. The developmental changes were faster in sholder than the other regions. Conclusion: This study showed that at first half of second month the epidermis of developing fetuses were contaning simple cuboidal epithelial cells without apparent differentiations, whereas at the end of this stage beginning of differentiation was observed. The superficial layer of the two layered epidermis known as periderm. This cells were appaered in amniotic fluid at first half of prenatal period. It presumed that, the mesenchymal tissue in vicinities of epidermis has inductive role on the differentiation of hair follicles, sebaceous and sweat glands. However we conclude that the skin and its associated structures are differentiating from second half of fourth month of antenatal life.

Abstract: 

Objective: Identification of toxigenic and nontoxigenic fungi agents isolated from feedstuffs, understudy. Design: laboratory study. Samples: Nineteen different samples of feedstuffs such as corn, oat, silage, concentrated feed, fat powder and etc. Procedure: After processing of the samples, they were cultured (using inoculation & streak culture methods) on sabouraud glucose agar containing chloramphenicol, potato glucose agar,czapek-dox agar and rosebangal agar media under standard laboratory technical conditions. Statistical analysis: Chi-square and t-test. Results: The most frequent isolated fungi were: Aspergillus (63.2%), Penicillium (36.8%), Mucor (31.6%) and Cladosporium (26/3%), respectively. According to the colony counts, Fusarium colonies were the most abundantly isolated from silage and concentrated feeds (118 colonies).Among the isolated Aspergillus species, A.fumigatus (18.5%), A.flavus (35.9%), A.niger (25.9%) and A.sPP (29.6%) were identified. There was a significant defference between Aspergillus and the other fungi. These differences were significant, respect to suspected toxigenic and nontoxigenic species, as well. It means that toxigenic species were isolated more significantly than nontoxigenic agents. Conclusion: With attention to presence of toxigenic fungi on the feeds, it should be considered to plan a program for identifying fungi(spacially toxigenic fungi )in different feedstuffs .After this step, in order to hygienic control of fungi on feeds, it is necessary to design some programs into the future.

Abstract: 

Objective: Detecting of seropositive cattle to BVD virus by indirect ELISA using milk and serum samples from individual cows, comparing the use of milk instead of blood serum for determining the BVDV infection in cattle herds. Design: Bovine viral diarrhea seroprevalence survey in cattle using milk and serum ELISA by retrospective study. Animals: One hundred and eighty eight milky cows and 45 alves 0.5-2 years old (Native and hybride) from 24 cattle herds in subord of Urmia. Procedure: Preparing serum and skim milk for detection of antiBVDV antibody by indirect ELISA. The sera were diluted 1:25 and the milk samples were used as undiluted. The sera and milk which had OD equal or higher than 2.5 time OD of reference negative control serum and milk, considered as ELISA-positive. The data obtained from 188 matched sets of milk and serum were statistically compared with each other to determine the precentage of correlation between them. Statistical analysis: Student’s t and chi square tests. Reults: Out of 188 pairs milk and serum, 52 cases (27.65%) of milk and 59 (31.38%) of serum samples were ELISA positive. The data showed 96% correlation between the results of milk-EllS A and serum-ELISA. Conclusion: The present study showed that milk-ELISA is well performed in compared with serum-ELISA test. However the output of milk-EllS A was 3.72% less than serum-ELISA in detection of animals infected with BVDV, but on significant differences was found between the results gained by milk-ELISA (27.65%) and serum- ELISA (31.3 8%) test by student’s t -test. Therefore, the milk can be used instead of serum in ELISA for detection of infected herds as a screening test.

Abstract: 

Objective: To study the effects of water chiller on microbiological quality of poultry carcasses before and after chilling process in 11 slaughter houses of Tehran and Gilan provinces. Samples: Seventy five poultry carcasses were collected from 11 industrial slaughterhouses of Tehran and Gilan provinces. Method: Fifty one poultry carcasses were from 9 industrial slaughter houses of Tehran province and 24 poultry carcasses from 2 industrial slaughterhouses of Gilan province, before and after chilling process, were collected and analysed bacteriologicaly according to American Public Health Association method. The tree chlorine content and temperature of water for every chiller was also measured. Results: Coli form total count of poultry carcasses which collected after chilling process showed higher load than before chilling in Tehran. Paired-samples T test indicated significant difference (P<0.05). One of 51 carcasses which were collected after chilling process in Tehran, and all the carcasses collected in Gilan, before and after chilling process, were E. coli positive. The isolated serotypes were O119:B14, O128:K67, O78:K80, O2: K1 and H7. One of 51 poultry carcasses of Tehran province, after chilling, was Salmonella entritidis positive. Free chlorine content of water in 8 slaughter houses, located in Tehran province, was not measurable. Threfore, it was measured in water of one of the slaughterhouses in Tehran and 2 slaughter houses of Gilan which were 0.5, 1 ppm and 0.1 ppm respectively. The mean temperatures: 10 standard error of water in chillers of the slaughterhouses of Gilan were 6.1 H.4 and 6.5±0.7°c respectively. Concluded: According to the results, water chillers may be consider as a risk of bacterial contamination of pultery carcasses. Therefor hygienic quality control of them is very important.

Abstract: 

Objective: Determination of frequency of subclinical ketosis of dairy farms of Kerman by measurement of betahydroxy butyrate. Design: Cross sectional study. Animals: A total of 90 lactating cows in 3-6 weeks of lactation. Procedure: In this study the frequency of subclinical ketosis in 90 cows of 11 dairy farms containing 3542 cows were evaluated. Cows were selected in 3 to 6 weeks after parturition. The blood samples of each week for each cow were submitted to laboratory for detection of BHB and glucose. Statistical analysis: Student t-test, analysis of variance. Results: Thirteen (14.4%) and 5 cows (5.55%) have showed ketonemia with cut of point of BHB levels (> 1.2 mmol/l) and (> 1. 7 mmol/l) respectively. The percentage of subclinical ketosis in city of Kerman is low but this is similar to some reports of the other parts of the world with range of 7-34%. The range of the glucose levels in these cows was 28-42 mg/dl and there is a reverse relationship between level of glucose and ketonemia. Clinical implication: It seems that some percentages of our daires suffer from subclinical ketosis, that is affect on lactation level and some other organs mechanisms. However, further investigations should be gathered about the real cut of point of BHB values in Iranian cows.

Abstract: 

Objective: To clarify the season in which GSH-PX, the index of blood selenium status, is in its critical condition. In addition specific pathological changes due to selenium deficiency in skeletal muscle and the heart was investigated. Animals: In this study, blood sampling were taken of 2400 cilinicaly normal sheep and 27 lambs suspected for seleniom deficiency. 10 selenium deficinet lambs were also autopsysed for pathological changes. Procedure: GSH-PX was measured in 2400 blood samples taken of normal sheep in 3 towns in west Azarbaidjan. Blood samples were also collected from 27 lambs suspected for selenium deficiency. Ten lambs with clinical signs of selenium deficiency were necropsied and gross and microscopic changes in the hearts and skeletal muscles were studied. Statistical analysis: Season’s variations were analysed by student "t" test. Results: This investigation showed that blood GSH-PX in sheep in the all understudied areas, was significaly lower in winter than summer. The lambs with clinical signs of selenium deficiency had margina1 blood GSH-PX and showed extensive degenrative changes in the hearts and skeletal muscles. Conclusion: The results showed that in winter, blood GSH-PX of sheep in west Azarbaidjan declined to the critical level and in some places like Urmia lead to developing of the clinical form.

Abstract: 

Objective: Detection of infectious bronchitis viruses by RTPCR/RFLPs in poultry fanns of Iran. Design: Longitudinal study from 1997 to 2003. Samples: Tracheas, lungs and kidneys of suspected flocks to respiratory diseases. Procedure: From 1997-2003, tissues samples including lung, trachea and kidney, had been prepared from broiler and layer flocks were submitted to avian virology laboratory of poultry diseases section in order to isolate respiratory viral diseases viruses. A total number of 50 infectious bronchitis viruses (IBV) were isolated in embryonated chicken eggs. The infected embryos displayed stunting, urate deposition in the mesonephros or death after three passages. Twelve isolates that had showed typical signs in embryos, were selected for molecular identification. Viral RNA was extracted by RNXTM plus (CinnaGen Co.) using chlorofonn/ Isoamyl alcohol, Isopropanol, Ethanol and DEPC water. cDNA was prepared from extracted RNA with RT enzyme, RH primer, RT buffer, dNTP and Rnase inhibitor. For PCR reaction, buffer PCR IOX, MgCI2, SI oligo5’ & 3’ primer, ampli Taq DNA polymerase and dNTP were added to cDNA and then PCR was conducted in thermal cyeler. The PCR products were analyzed on a 1% agarous gel and Ethidium Bromide staining. The SI glycoprotein genes of IBV strains appeared to be above 1600 bp in size. PCR products were digested by HaeIII, EcorI and HindIII, according to the manufacture’s recommendation. Results: Base on RFLPs patterns and comparison with RFLP references patterns (793/B, D274, M41, H120), 8 of 12 strains showed 793/B pattern and the rests (4 of 12) showed Mass pattern in RFLPs. Clinical implications: Regarding to low homology and weak cross protection between 793/B serotype and vaccinal strain (Massachusetts), prevention and a controled strategy against IB should be altered.

Objective: The effect of xylazine-ketamine on cardiovascular system and respiratory system was evaluated by measurement of arterial blood pressure, blood gases, temperature, heart and respiratory rate. Design: Self controlled study. Animals: Five healthy sheep with an average weight of 21.4 kg were used in this study. Procedure: Xylazine (0.2 mg/kg IM) was administrated 15 minutes prior to utilization of ketamine (l0 mg/kg IV) in all animals. All baseline measurements (heart rate, respiratory rate and ...) were taken before the xylazine administration and were taken again at 5, 15, 30, 45 and 60 minutes intervals after induction of anesthesia with ketamine. Arterial catheters flushed with 2:1000 heparin solution were placed by using local anesthesia into the carotid artery via a 5 cm skin incision for measuring arterial blood pressure and collecting blood samples. Statistical analysis: Repeated measure analysis of variances design and least significant difference were used to analyze data. Results: On the basis of these results, heart rate did not change significantly. Mean arterial blood pressure decreased significantly at 30, 45, and 60 minutes after anesthesia. PaO2 declined significantly at 60 minutes and PaCO2 at first increased at 5 minute, then decreased at 15, 30, 45, and 60 minutes but remained significantly higher than before anesthesia, but respiratory rate did not change significantly. Temperature declined significantly at 5, 15, 30, 45 and 60 minutes after anesthesia. Conclusion: According to this study, xylazine-ketamine combination has a little depressant effect on cardiovascular system. This combination is responsible for a little disturbed ventilation, decreased PaO2, increased PaCO2 and declined body temperature in anesthesia.

Abstract: 

Objective: Survey of antibiotic effects on serological titer of Mg and Ms infected broiler breeders. Design: Observational study. Animals: A total of 42 ross broiler breeders. Procedure: Thirty-six broiler breeders at 35 weeks old from an infected (Mg and Ms positive) poultry unit and six broiler breeders from a non-infected (Mg and Ms negative) poultry unit were kept in separated cages as recommended in Ross broiler breeder catalogue at the hospital of veterinary faculty of Urmia university. Blood samples were collected from broiler breeders in order to determine serological titers using rapid plate serum agglutination test (RPSAT) and ELISA, before and after administration of lincospectin, tiamulin, tylosin, ciprofloxacin and enrofloxacin antibiotics for five days with recommended dosages of each antibiotics. Statistical analysis: SPSS statistical analysis program using ANOVA and Two tailed pair t-test were used to analyze the data. Results: The ELISA titers of the infected birds (within and among the groups) were differed significantly (P<0.05). While ELISA titers of non-treated infected birds (group 6), increased significantly during this study but those of treated birds (groups 1-5), decreased indicating that overall, antibiotics such as lincospetin, tiamulin, tylosin, ciprofloxacin and enrofloxacin reduced not only the severity of the infections but also their ELISA titers. Comparison of ELISA titers before and after treatment indicates that all antibiotics affect the overcome of the Mg and Ms infections but lincospectin, tiamulin and ciprofloxacin had the highest effect on both Mg and Ms ELISA titer while tylosin tartarat and enrofloxacin had the lowest effect.Conclusion: Antibiotics affect the outcome of the Mg and Ms infections in broiler breeders and reduce serological titers of Mg and Ms infected birds but do not clear the birds from the infections.

Abstract: 

Objective: To compare the field efficacy of Florfenicol with Tilmicosin in the treatment of naturally occurring enzootic calf bronchopneumonia. Design: Randomized controlled trial. Animals: A total of 70 Holstein calves between 1-6 months old in three dairy farms of Mashhad suburb were used. Procedure: Calves with visual signs of pneumonia were entered into the trial. After physical examination, clinical findings were recorded. They were weighed and blood samples collected by venipuncture. They were randomly assigned to received either Florfenicol (20 mg/kg bw, IM, 2 injections 48h apart, 35 calves) or Tilmicosin (10 mg/kg bw, SC, 1 injection, 35 calves). Clinical measures of efficacy included mortality, rectal temperature, illness index scores, assessment of treatment success or failure, and the number of relapses or reinfections. Also, hematological indices, total plasma protein and fibrinogen were studied on day 0 and day 4 after the treatment. Statistical analysis: Independent t-test, Mann - Whitney and Chi Square. Results: There were not any significant differences between two treatment groups (p>0.05). Resolving clinical sings in Florfenicol and Tilmicosin treatments were, 88.5% (31 cases) and 85.7 % (30 cases) respectively, which were not statistically significant (P>0.05). No significant adverse reaction was noticed with either drugs.Conclusion: Results indicate that Florfenicol and Tilmicosin are comparable in the treatment of enzootic calf bronchopneumonia.

Abstract: 

Objectives: Identification of Monogeneans and determination of their population density effect an Barbus grypus and B. sharpeyi in the Karoon river in Ahwaz. Design: Observational study. Procedure: Fish were caught by net, and were identified on the basis of their morphological characteristics and formulas of their scales and teeth. The body surface and mainly branchiae of the fish were searched for Monageneans. The live or dead Monogeneans were then fixed by amonium picrate. Identification of the Monogeneans was based on the shape and arrangement of hooks and anchors in opisthohaptor and the male reproductive organs. Statistical analysis: Analysis of variance (Anova), mean and standard deviation and standard error. Results: Indentification of Dactylogyrus pavlovskyi, D. barbioides, Dogielius persicus,Gyrodactylus sprostonae and Paradiplozoon sp. in Barbus grypus and D. pavlovskyi ,D. barbioides, D. persicus, D. anchoratus and D.carassobarbi in Barbus sharpeyi. Conclusions: It is the first report of the presence of Gyrodactylus sprostonae and Paradiplozoon sp. on B. grypus in Iran. This survey revealed that the host specificity among these Monogeneans are decreased. Also, the impaction of these parasites population density on both fishes were not significant.

Abstract: 

Objective: Considering the role of parasite in contamination of human beings and domestic animals and lacking information in this region, this study was done to determine the prevalence of carnivores, cestodes in Kashan. Design: Descriptive and observational study. Animals: A total of 142 carnivors involved in 70 dogs, 40 jackales, 22 foxes and 10 wolves of both males and females between 2 months to more than 5 years old. Procedure: This study was conducted on 142 carnivores during four seasons which huntered by shotting. After huntering small and large intestine, were isolated. Then samples were fixed in 10% formalin and their identification was performed based on parasitological characteristics. Statistical analysis: Data were classified with descriptive statistics and chi-square. Results: Seven species of cestodes were found in gastrointestinal tract of the samples. Overall contamination rate was 67/6%. Contamination rate for species of parasites that found in this study were: Taenia hydatigena: wolf 70%, dog 52.9%, jackal 40% and fox 36.4%. Joyexiella echinorhyncoides: wolf 20%, fox B.6%, dog 11.4%, jackal 7.5%. Echinococcus granulosus: dog 55.7%, wolf 40%, jackal 40%, fox 13.6%. Multiceps multiceps: wolf 40%, fox 18.2%, jackal 7.5%, dog 4.3%. Dipylidum caninum: wolf 30%, fox 22.7%, dog 10%, jackal 10%. Conclusion: Contamination rate for cestodes especially zoonotic parasites was greater than expectation in Kashan region. In this respect, appropriate controlling measures should be taken and it is recommended to determine the most appropriate preventive method.

Abstract: 

Objectives: Side effects of 100 and 200ppm clove oil, were studied on some hematological parameters, serum enzymes and brain, liver, kidney, spleen and gill of common carp (Cyprinus carpio). Animals: Common carp (Cyprinus carpio). Procedure: Anaesthesia in common carp was induced by 100 and 200ppm clove oil under acceptable water quality conditions at 20±2°c and hematological and biochemical parameters and histopathology of hematopoietic tissues (kidney and spleen), liver, brain and gills were studied. Statistical analysis: SPSS and SX software one way ANOVA and student t-test. Results: No significant differences were found in levels of WBC, RBC, haematocrit, haemoglobin, MCH, MCHC, alanintransaminase (ALT), aspartatetransaminase (AST), alkalinphosphatase (ALP) and lactatedehydrogenase (LDH) between the anaesthetized fish and control groups (0.3>P>0.1). Also, there was not any histological abnormality observable in liver, kidney, spleen and gi11s of anaesthetized groups. However, only hyperemia was seen in brain of both groups. Conclusion: According to the results administration of clove oil, up to 200ppm in aquaculture is safe and recommended.
