in vivo studies of gallibacterium anatis infection in chickens.	the aim of the present study was to investigate the pathology in normal or immunosuppressed chickens followed intravenous or intraperitoneal inoculation with a well-characterized strain of gallibacterium anatis. two groups of 30 15-week-old commercial brown laying chickens were used, having been screened and found negative for gallibacterium organisms. one group was treated with 5-fluorouracil to promote heterophil depletion, while the other was saline treated. ten days later 15 chickens from ea ...	2004	15276980
tissue distribution of haemolytic gallibacterium anatis isolates in laying birds with reproductive disorders.	gallibacterium anatis biovar haemolytica has been suggested to have a causal role in peritonitis and salpingitis in chickens. therefore, the aim of this study was to investigate the occurrence of g. anatis biovar haemolytica in chickens with reproductive disorders. one hundred and forty one birds from 31 layer flocks were submitted for necropsy and the following organs were examined for bacteria: choana, trachea, lung, heart, liver, spleen, ovary, oviduct, duodenum and cloaca. examination for es ...	2009	19089694
the rarely reported tet(31) tetracycline resistance determinant is common in gallibacterium anatis.	the present investigation was undertaken to identify and characterize the tetracycline resistance determinant in 22 gallibacterium anatis strains for which no determinant was identified using primers specific for tet(a, b, c, d, e, g, h, k, l, m, o). a recent study found tet(b) to be the most prevalent tetracycline resistance determinant in a larger collection of g. anatis field strains from mexico and denmark. however, in 41% of the tetracycline resistant strains no determinant could be assigne ...	2010	21145184
histopathologic findings in chickens experimentally infected with gallibacterium anatis by nasal instillation.	histologic findings in chickens experimentally infected by nasal instillation with reference strains of gallibacterium anatis are described. no clinical signs were observed in experimentally infected birds; however, sequential histologic examinations of trachea, lung, air sacs, and liver revealed lesions in all infected chickens. our observations suggest that the reference strains of g. anatis used in this experiment are capable of causing primary infection in chickens. despite that the experime ...	2010	21313855
