Abstract

Aim: To describe prevalence and pathology of pneumonic pasteurellosis in sheep slaughtered in Kashmir Valley, India.Material and Methods: 2155 ovine lungs from various abattoirs were examined. Lungs with gross pneumonic lesions were collected. Specimens taken from the different lobes were collected for bacteriological culture. Based on the bacteriology, tissues were processed for histopathological examination. Duplicate sections were stained for connective tissue by Masson’s Trichrome Stain, elastin by Hart’s method, neutral and acid mucopolysaccharide by Combined Alcian Blue PAS technique, and mast cells by Toluidine Blue Stain.Results: Out of 956 grossly pneumonic lung samples, Pasteurella spp. was isolated from 398 affected lung samples giving an overall prevalence of 18.46% (398/2155) in the population studied. The prevalence was significantly (p≤0.01) higher in winter (29.76%) and spring (21.03%) as compared to autumn (12.35%) and summer (9.4%). Gross and histopathological examination revealed features typical of fibrinous pneumonia. Conclusion: Ovine pasteurellosis is highly prevalent in Kashmir Valley. These findings will help in developing better control measures against the disease to prevent the ensuing economic losses.

Hindistan’ın Kashmir vadisi koyun pasteurellozisi üzerine prevalans ve patolojik araştırmalar

Abstract

Amaç: Araştırmanın amacı Hindistan’ın Kashmir vadisinde kesime tabi tutulan koyunlarda pasteurollozisin prevalans ve patolojisini belirlemektir. Gereç ve Yöntem: Farklı mezbahalardan elde edilen 2155 koyun akciğeri incelendi. Büyük pneumonik lezyon bulunduran akciğerler toplandı. Bakteriyolojik kültür için farklı akçiğer loplarından örnekler toplandı. Bakteriyolojik incelemeye göre dokuların histopatolojik incelemeler yapıldı. Örneklerde bağ doku Masson’s Trichrome boyası, elastin Hart’s metodu, neutral ile asit mukopolisakkaritler Combined Alcian Blue PAS tekniği ve mast hücreler Toluidine Blue boyası ile boyandı.Bulgular: İncelenen 956 lezyonlu akciğerin 398 adetinden Pasteurella spp. izole edildi. İncelene genel populasyon dahil edildiğinde genel prevalans %18.46 (398/2155) olarak belirlendi. Kış (%29.76) ile ilkbahar (%21.03) mevsiminde gözlenen prevalansın yaz (%9.4) ve sonbahar (%12.35) mevsiminden istatistiki olarak önemli (p
