Abstract

Escherichia coli tarafından oluşturulan koligranüloma barsak
duvarları, mezenter ve karaciğerde nodüler granullerle
karakterizedir. Mevcut araştırma bir güvercinde makroskobik
ve histopatalojik olarak tanısı konulmuş koligranülomayı
tanıtmaktadır. Makroskobik olarak karaciğer, uviduk,
pankreas ve barsakların serozal yüzeylerinde çok odaklı
nodüler lezyonlar gözlendi. Histopatalojik inceleme için
etkilene organlardan örnekler alınarak boyamalar yapıldı.
Hasta organlardan bakteriyel muayene için incelemeler yapıldı.
Etkilenen organlardan E. coli izolasyonu gerçekleştirildi.
Histopatalojik olarak bakteri kolonilerinin etrafında
heterofiller, çok çekirdekli dev hücreler, makrofajlar ile lenfositler
gözlendi. Ayrıca kazeöz nekrozlu tipik granülomalar
gözlendi. Makroskobik, histopatolojik ve mikrpbiyolojik
bulgular koligranülomayı doğrulamaktadır. Bilindiği kadarı
ile mevcut araştırma güvercinlerde rapor edilen ilk koligranüloma
vakasıdır.

Coligranuloma in a pigeon

Abstract

Coliganuloma is characterized by nodular granulomas in
liver, mesentery and walls of intestine and is caused by
Escherichia coli. This article describes gross and histopathological
characteristics of coligranuloma in a pigeon. Grossly,
there were observed multifocal nodular lesions on the serosal
surface of the intestine, oviduct, pancreas, gizzard and
liver. For the histopathological study, tissue samples from
the affected organs were taken and stained. The affected
organs were processed for the bacteriological examination.
Escherichia coli was isolated from affected tissues. Histopathologically,
there were found typical granulomas with
caseation necrosis and bacterial colonies in central area
surrounded by lymphocytes, macrophages, multinucleated
giant cells and heterophils. Based on gross, histopathological
and microbiological findings, coligranuloma was diagnosed.
To the best of our knowledge, this is the first report
of coligranuloma in pigeon.
