Composition and antibiotic susceptibility of opportunistic pathogenic microflora in poultry farms aimed at egg or meat farming

Abstract

There are a lot of factors facilitating antibiotic resistance in poultry farming, such as: genetic characteristics of microbiome, immune status of poultry, stress-producing technology of industrial poultry welfare, and the use of antibiotics with the purpose of disease prevention or medication. In both veterinary and animal-farming practice in the Russian Federation ansamycins, carbapenems, semisynthetic penicillins, cephallоsporins of different generations, fluroquinolones, macrolides and azalides, tetracyclines and glycopeptides are mainly used. Detection of the strains of pathogenic and opportunistic pathogenic microflora resistant to these antibiotics is considered to be important not only for veterinary but also for medicine. We have done the research on opportunistc microbiocenosis in poultry farms aimed at egg or meat farming located in the Ural area. It was stated that dominating strains in opportunistic pathogenic microflora are Enterococcus faecium and Pseudomonas aeruginosa, whereas S. aureus, S. epidermidis, S. saprophyticus, Ent faecalis, Enterobacter spp, P. vulgaris, P. mirabilis, E.coli are less frequently detected. Proportion of the above mentioned microorganisms differed depending on the profile of a poultry farm. The research done have shown that spreading of antibiotic resistant strains of opportunistic microflora in poultry farms have reached high level. The most of detected strains had low susceptibility or resistance at least to one target antibiotic. A significant number of P.aeruginosa and S.aureus strains not sensitive to carbapenems and fluroquinolones, as well as of E. faecium strains resistant to vancomycin, have been detected.

“…(2.6%), and Escherichia coli (2.2%). Additional microorganisms, such as Staphylococcus saprophyticus , Enterobacter spp., and other species, comprised a minority fraction, totaling less than 1% of the microbial spectrum [ 4 ]. On farms focused on egg production, a distinct distribution emerged, with notable variation in the detection frequency of different strains.…”

Perspectives for Recognition and Rapid Detection of Foodborne Pathogenic Bacteria Based on Electrochemical Sensors

“…Foodborne disease caused by human ingestion of pathogens infected food is the main sources of food safety problems. Pathogenic bacteria that cause foodborne disease are Escherichia coli (E. coli), Salmonella spp., Staphylococcus aureus (S. aureus), Listeria monocytogenes (Lm), Campylobacter spp., Clostridium botulinum, Shiga toxin-producing Escherichia coli and Enterobacter sakazakii [1,2]. The main symptoms of foodborne pathogens on the human body are dysentery, food poisoning, diarrhea and even death [3].…”

“…Hensimmunity may have the potential to cause disease and require antimicrobials to control disease incidence. Krivonogovaet al [2] stated that using antimicrobials is the most effective way to fight pathogenic and opportunistic bacteria. The opportunistic microorganisms that adapt most quickly to antimicrobials are Staphylococcus aureus, Pseudomonas aeruginosa, and Enterococcus [2].…”

The opportunistic microorganisms that adapt most quickly to antimicrobials are Staphylococcus aureus, Pseudomonas aeruginosa, and Enterococcus [2]. Pseudomonas aeruginosa in hens is an opportunistic pathogenic bacterium that can cause respiratory infections, diarrhea, and septicemia.…”
