Screening of Microflora in Rejected Broiler Chicken Organs

摘要

The aim of this study was to link the assessment of pathogenic and conditional pathogenic microorganisms with different types of lesions discovered during the poultry slaughtering process.Harvested 13 livers,6 spleens,21 kidneys and 10 hearts with gross lesions (steatosis,perihepatitis,multifocal military necrotic hepatitis,degenerative and vascular reactions and kidney conjunctive infiltration and heart hemorrhagic and degenerative lesions)from young slaughtered poultry were submitted to microbiological exam.Selective culture media such as: CIN (Schiemann)agar,Wauters agar,MacConkey agar,Christensen media,Simons agar were used for pathogenic and conditional pathogenic microorganisms detection.In case of the poultry livers Pseudomonas spp.(5/6 ),Enterococcus spp.(3/6 )and yeasts (4/6 )were correlated with military necrotic hepatitis ; meanwhile non-specific hepatopathies were linked to E.coli (6/7 ),yeasts (5/7 )and Enterococcus spp.(5/7 ).The specific microflora for spleens was Pseudomonas aeruginosa (2/3 )in correlation with hemorrhagic aspects and yeasts (2/3 )with normal aspect,respectively.The detected microflora for kidneys was E.coli (8/21),yeasts (12/21)and Enterococcu.s spp.(2/21).For all samples of hearts no microflora was detected.Yeasts were isolated from the majority of the samples; probably they have exogenous origin coming from the slaughtering process,manipulation and transport of samples.
