CITROBACTER - THE NEAREST RELATIVE OF SALMONELLA
Introduction. The article presents analysis of literature data of the biological characteristics of microorganisms of Citrobacter spp. genus, which have a lot in common with Salmonella spp. In the modern world these microorganisms possessing pronounced biological plasticity are capable for wide dissemination in the environment and long-term persistence in humans and in animals, including birds. The main aim of the work was to analyze literature regarding biological properties of Citrobacter. The goal of the work was to analyze the literature data for biological characteristics of Citrobacter spp. microorganisms, which have a lot in common with Salmonella spp. Material and methods of research. International and national documents, scientific literature, isolates from animal origin products.Results of research and discussion. There were analyzed international and national documents, scientific literature, test with isolates were described.Methods used for indication of Salmonella and Citrobacter include: classical bacteriology, ELISA, lateral flow immunochromatographic assays and PCR.Citrobacter spp. has different serological variants. Cultures of Salmonella enteritidis and Citrobacter spp., that were isolates from sick birds, give false positive reaction with pullorum antigen. Therefore, methods of detecting and differentiation of the Salmonella spp. of the familial microorganisms of the genus Citrobacter require careful laboratory diagnostics.Conclusions and prospects for further research. During the control and monitoring of salmonellosis in poultry farms required a thorough laboratory diagnostics to identify and differentiate Salmonella pathogen, whose closest relatives are Citrobacter spp.
