“…In fact, in this study, all S. Infantis and S. Gallinarum strains were found to be resistant to the antibiotics evaluated in the aminoglycoside group (gentamicin and streptomycin). These results were similar to those reported for S. Gallinarum in Nigeria and Mali in cloacal swabs and poultry organs [43,44] and S. Infantis in Ecuador, England, and Japan in environmental samples from farms and poultry meat [12,14,45].…”

Background and Aim: Salmonella has been identified as one of the most widely distributed zoonotic pathogens in broiler litter. Multidrug-resistant strains have been isolated from salmonellosis outbreaks, compromising the success of their treatment. This study aimed to isolate and identify Salmonella spp. serovars in healthy broiler litter in Tolima (Colombia), determine their resistance to different antimicrobials, and detect genes associated with β-lactam resistance that could be useful to control Salmonella spp. in poultry. Materials and Methods: In total, 45 broiler litter samples were collected. Salmonella spp. was isolated and identified using selective and differential culture media and biochemical tests. Molecular confirmation of the pathogen was performed with the invA gene and serotyping by Kauffman–White scheme. Antimicrobial susceptibility to 15 antibiotics was determined by Kirby–Bauer method. In cefotaxime-resistant strains, blaCTX-M-F, blaCTX-M-1, blaCMY, and blaTEM genes were evaluated by polymerase chain reaction (PCR). Results: In total, 817 presumptive strains were obtained from xylose lysine deoxycholate and Salmonella Shigella agars and subcultured on xylose-lysine-tergitol 4 and MacConkey agars, from which 150 strains were isolated; 29 of these strains were presumptive for Salmonella spp. after performing biochemical tests and 16 were confirmed by PCR as Salmonella Infantis (15) and Gallinarum (1). All strains were found to be multiresistant to antibiotics, showing three different profiles and isolates resistant to cefotaxime, and the blaCTX-M gene was detected. Conclusion: This is the first study to isolate S. Infantis from broiler litter in Colombia. All isolates exhibited resistance to the evaluated antimicrobials, suggesting the misuse of antimicrobials in small- and medium-sized poultry farms. The presence of Salmonella enterica serovar Infantis is a public health problem. Thus, regular monitoring of poultry litter is recommended, as these bacteria can be transmitted to humans through animal products or contaminated environments.

“…The main sources of human contamination are products of avian origin, such as eggs and poultry meat [7] . The fight against avian salmonellosis in Mali is mainly based on the abusive use of antimicrobial products, in this case antibiotics [16,17] . These molecules block the growth of bacteria or destroy them.…”

This antibiotic resistance represents a threat to human health and a real public health problem [16,11,5,6] . Certain strains of multi-resistant Salmonella of animal origin are suspected of having acquired their resistance genes before being transmitted to humans via the food chain [7,14] .…”

The aim of this study was to determine the antibiotic resistance of Salmonella strains isolated from poultry products from Bamako's markets and slaughter areas. It involved the analysis of 64 Salmonella strains isolated from poultry eggs and organs. The antibiotypic profile of these strains was determined using the Kirby-Bauer agar diffusion method and the recommendations of the Comité de l'antibiogramme de la société française de microbiologie (CA-SFM). This work resulted in high rates of resistance to imipenem (93.75%), followed by kanamycin (84.37%) and doxycycline (67.18%). In addition, low levels of resistance were observed to gentamicin (12.5%) and flumequine (26.56%). Sequencing of the complete genome of the isolated strains and the use of bioinformatics tools made it possible to obtain certain genes conferring antibiotic resistance, namely marB, marA, marC, marR, mdtG, mdtQ, folA, ksgA, rarD and STM169. Some of these genes are multi-resistant to antibiotics (marB, marA, marC).

“…and Escherichia coli respectively and are considered as one of the main causes of morbidity and mortality either as a primary or secondary pathogen 2 . In West Africa, salmonellosis alone causes significant economic losses with mortalities of up to 90% 3 . Antibiotic therapy with synthetic molecules is one of the ways to control these diseases.…”

“…These include antibiotics of the tetracycline class, sulfonamides, penicillins, quinolones, aminoglycosides, polymyxins and macrolides 97,98 . The frequent use of these different classes of antibiotics has allowed over the years the emergence of multidrug resistant strains of Salmonella and Escherichia coli 3,11,13 . Thus, many authors through their work have demonstrated that several strains of Salmonella isolated from chicken farms have developed resistance to tetracyclines, sulfonamides, quinolones and polymyxins 16,99,100 .…”

Salmonella spp. and Escherichia coli are the two leading causes of foodborne bacterial zoonosis in the world. Respectively responsible for avian pullorosis/typhosis and colibacillosis in poultry, these pathogens represent major constraints for the poultry industry (layers, broilers) in the world because of the mortality and economic losses generated. The isolation of multidrug resistant Salmonella and E. coli strains in poultry farms in several parts of the world reflects the global aspect of the problem. Antibiotics are essential in the treatment and control of these two bacterial diseases. Resistance results in the progressive ineffectiveness of several families of antibiotics, which constitutes a threat to animal health, food safety and public health. This article reviews the various studies conducted on avian salmonellosis and colibacillosis. The antibiotic molecules to which Salmonella spp. and Escherichia coli strains are resistant are discussed.The virulence and resistance genes associated with the different serotypes are reported. Finally, the risk factors, the impact on public health and some pyhtotherapeutic solutions are described. A better knowledge of this information will allow the poultry industry to make further progress in the elimination of salmonellosis and avian colibacillosis, the reduction of antibiotic use and the potential public health risks.
