چکیده
In a commercial layer farm of 1500 flock capacity, daily mortality of 2 to 3 birds was noticed for a period of 7 days. The birds exhibit the signs of dullness, paleness in comb along with blood tinged exudates from the nostril. On postmortem examination, severe congestion vascular disturbance in various visceral organs were noticed in all birds. Tissue samples were collected aseptically and subjected to bacterial isolation, it was revealed as Pasturella multocida. However, the lesions recorded were atypical of fowl cholera. Antibiotic sensitivity test revealed that the isolate was sensitive to sulphadiazine, co-trimoxazole, ceftriaxone, chloramphenicol, gentamicin, Amikacin and Amoxyclav. As per the Antibiotic sensitivity test results the flock was treated with sulphadiazine + trimethoprim combination and the recovery was observed after 5 days. The vascular disturbance in visceral organs may be due to the endotoxin produced by the organism.
