“…Interestingly, only two isolates were susceptible to all kinds of antimicrobials, which stands with the results of previous studies [52]. Importantly, from the Campylobacter isolates 43.9% were resistant to three types of antimicrobials; tetracycline, ciprofloxacin, and gentamycin.…”

“…Interestingly the observed resistance to nalidixic acid was very low (7.31%) compared to the previous study which was reported as 80% [13]. A study conducted in Brazil revealed that 90.7% and 81.5% of the strains, respectively, were resistant to both ciprofloxacin and nalidixic acid [52]. Again the tetracycline resistance percentage; 39% was lower than the previously reported.…”

The persistence of Salmonella and Campylobacter in chicken meat is a considerable public health risk and a future challenge. This study aimed to determine the prevalence of Salmonella and Campyl-obacter in poultry processing lines where different chlorination techniques were used. The sam-ples were collected from four types of processing plants considering the chlorine concentration used in the chill tank, which ranged from 2 ppm to 50 ppm. Salmonella and Campylobacter were isolated from carcass washings, neck skin, and, caecal samples. Subsequently, an antimicrobial susceptibility test was performed for the isolates. The results revealed the overall prevalence of Salmonella and Campylobacter was 78.25%, and 64% respectively. Positive percentages of Salmonella and Campylobacter were high in carcasses compared to neck skin and caeca. Carcass Campylobacter counts at higher chlorine concentrations ranging from 20 – 50 ppm was significantly low (p

“…The variations in the breakpoints can result in significant changes in the final MIC, which will affect clinical decisions and official data reports (Kassim et al 2016). A previous study compared the MIC results for Campylobacter jejuni strains according to the EUCAST and CLSI values and showed an agreement between these guidelines, which indicates that data based on both parameters could be compared (Paravisi et al 2020). A similar analysis was performed in the current study, and the results showed good agreement for gentamicin and enrofloxacin, indicating that the results from both breakpoints were similar.…”

Antimicrobial and disinfectant resistance of Salmonella Heidelberg from Brazilian flocks did not increase for ten years (2006-2016)

Salmonella is a major cause of foodborne illness worldwide, and poultry and its derived products are the most common food products associated with salmonellosis outbreaks. Some countries, including Brazil, have experienced an increased prevalence of Salmonella Heidelberg among their poultry flocks. Some isolates have also presented high resistance to antimicrobial agents and persist in the poultry farm environment. This study aimed to compare the susceptibility of S. Heidelberg strains isolated in 2006 with those isolated in 2016 against disinfectants and antimicrobial agents. The results showed that all the strains were highly susceptible to sodium hypochlorite, regardless of the conditions and year of isolation. Resistance to benzalkonium chloride varied according to the conditions applied, but not to the year of isolation. Increased antimicrobial resistance from 2006-2016 was observed only for tetracycline. The results suggest that the antimicrobial and disinfectant resistance of S. Heidelberg did not increase for ten years (2006-2016). However, further analysis should include a larger number of S. Heidelberg isolates from poultry origin and additional antimicrobial agents for more precise conclusions about the increasing in antimicrobial resistance in the last years.

“…Lynch et al [ 35 ] detected the Tet(O) gene in 100% of thermophilic Campylobacter tetracycline-resistant ( n = 119) recovered from the skin and cecal content of chickens in Ireland. Paravisi et al [ 36 ] determined the presence of the Tet(O) gene in 42.8% (12/28) of phenotypic Campylobacter resistance isolated from carcasses and cuts of chickens sampled in Brazil. Wozniak-Biel et al [ 37 ] found that 78.6% of strains isolated from chickens in Poland were resistant to tetracycline, and all of them included the Tet(O) gene.…”

Prevalence, Tetracycline Resistance and Tet(O) Gene Identification in Pathogenic Campylobacter Strains Isolated from Chickens in Retail Markets of Lima, Peru

et al. 2022

Background: In this study, we aimed to estimate the prevalence, tetracycline resistance and presence of Tet(O) in Campylobacter strains isolated from chicken in markets of Lima, Peru. Methods: A total of 250 chicken samples were obtained from traditional markets (skin, n = 120) and supermarkets (meat, n = 130). Samples were subjected to microbiological assays for identification of Campylobacter spp. according to ISO 10272-2017, and the isolates were then submitted to species identification by PCR. Phenotypic resistance to tetracyclines was assessed by the Kirby–Bauer test, and the presence of the Tet(O) gene was determined by PCR. Results: A significantly higher prevalence (p < 0.0001) of Campylobacter coli in skin samples from traditional markets (97.5%) than in meat samples from supermarkets (36.2%) was observed. On the other hand, Campylobacter jejuni was confirmed only in 3.1% of meat samples. All Campylobacter species isolated from skin and meat samples were phenotypically resistant to tetracyclines; however, the presence of the Tet(O) gene in C. coli was identified in 76.9% and 66.0% of skin and meat samples, no significant statistical difference (p = 0.1488) was found between these prevalence. All C. jejuni isolated from chicken meat samples from supermarkets were positive for Tet(O) gene. Conclusions: This study confirms the high prevalence of C. coli isolated from chicken sold in traditional markets and supermarkets in Lima, Peru, and in more than 70% of these strains, phenotypic resistance to tetracyclines could be linked with expression of the Tet(O) gene. It is necessary to evaluate other genes involved in resistance to tetracyclines and other groups of antibiotics in campylobacter strains isolated from chicken meat.
