Title

ISOLATION AND IDENTIFICATION OF PASTEURELLA SPP. IN THE UPPER RESPIRATORY TRACT OF HEALTHY AND UNHEALTHY HOLSTEIN (DAIRY CALF PNEUMONIA) CALVES

Pages

  147-153

Abstract

 Objective: To compare Pasteurella Spp. isolates of the nasopharyngeal cultures in healthy and unhealthy Holstein (dairy CALF pneumonia) calves.Design: Case control study.Animals: Sixty Holstein calves from two weeks up to sixmonth- old in dairy farms of Mashhad Suburb were selected.Procedure: In the affected calves, the clinical findings were recorded and nasopharyngeal swabs were also taken. Apparently healthy calves were chosen from the same farm as control.Statistical analysis: t-test, Mann- Whitney and Chi-square.Results: Clinical findings including respiratory rate, heart rate, rectal temperature, and illness index scores were significantly different between healthy and unhealthy calves (P<0.05). Differences between the isolation rates of various pathogens from healthy and unhealthy calves were evaluated by contingency table Chi-square analysis. PASTEURELLA MULTICIDA was isolated more frequently from nasopharynx in affected group than in control one (P<0.05). MANNHEIMIA HEMOLYTICA was isolated more frequently in affected ones than controls. However, its difference was not significant (P>0.05). Conclusion: Results indicate that PASTEURELLA MULTICIDA was isolated more frequently from nasopharynx in affected calves than in control group. However isolation of MANNHEIMIA HEMOLYTICA was not strongly associated with respiratory disease.
