ABSTRACT The possible increase of antibiotic-resistant bacteria in sewage associated with the discharge of wastewater from a hospital and a pharmaceutical plant was investigated by usingAcinetobacter species as environmental bacterial indicators. The level of susceptibility to six antimicrobial agents was determined in 385 Acinetobacter strains isolated from samples collected upstream and downstream from the discharge points of the hospital and the pharmaceutical plant. Results indicated that while the hospital waste effluent affected only the prevalence of oxytetracycline resistance, the discharge of wastewater from the pharmaceutical plant was associated with an increase in the prevalence of both single- and multiple-antibiotic resistance amongAcinetobacter species in the sewers.

The spread of V. cholerae strains with multiple antibiotic resistance limits the choice of effective means of etiotropic therapy for cholera, emphasizing the importance of finding ways to maintain efficacy in the face of the widespread prevalence of antibiotic-resistant bacteria. The review presents data of domestic and foreign literature on the antibiotic resistance of Vibrio cholerae and the prospects for the treatment of cholera in the modern period.

Abstract Background The occurrence and spread of antibiotic-resistant bacteria (ARB) due to the high demand in poultry industries are of great public health concern. Indiscriminate and abusive use of various antibiotics on a large scale causes antibiotic resistance (AMR) in animal-associated bacteria that may be pathogenic to humans. These bacteria are widely disseminated in the environment via animal waste. This study was therefore designed to assess the prevalence of multiple antibiotic resistance (MAR) among the environmental bacteria in poultry farms and to determine the risk contamination category of poultry by calculating the multiple antibiotic resistance index (MARI). Results More than half (58.2%) of the 511 total bacteria had MAR, and a number of bacteria were resistant to cefazolin (86.8%), fusidic acid (84.6%), ampicillin (79.3%), clindamycin (65.5%) and erythromycin (63.7%). These antibiotics are listed under the WHO’s criteria of critically and highly important antibiotics in human medicine. In this study, 39.53% of the MARI values, which indicate the contamination level in the environment, indicated a high risk, while 14.48% were ambiguous. Conclusion These results therefore have shown that MAR is present not only among humans and animals but also in environmental bacteria. The high prevalence of MAR and the MARI values, together with the resistance patterns of each bacterium, indicate various effects, including possible occupational risks among workers. This study provides an introduction to the AMR of bacteria in the environment. Further studies are needed to observe the horizontal transfer of the resistance gene and the overall mobile genetic elements in environmental bacteria.

Significant Difference

Information on the actual existence of antibiotic-resistant bacteria in rivers where sewage, urban wastewater, and livestock wastewater do not load is essential to prevent the spread of antibiotic-resistant bacteria in water environments. This study compared the antibiotic resistance profile of Escherichia coli upstream and downstream of human habitation. The survey was conducted in the summer, winter, and spring seasons. Resistance to one or more antibiotics at upstream and downstream sites was on average 18% and 20%, respectively, and no significant difference was observed between the survey sites. The resistance rates at the upstream site (total of 98 isolated strains) to each antibiotic were cefazolin 17%, tetracycline 12%, and ampicillin 8%, in descending order. Conversely, for the downstream site (total of 89 isolated strains), the rates were ampicillin 16%, cefazolin 16%, and tetracycline 1% in descending order. The resistance rate of tetracycline in the downstream site was significantly lower than that of the upstream site. Furthermore, phylogenetic analysis revealed that many strains showed different resistance profiles even in the same cluster of the Pulsed-Field Gel Electrophoresis (PFGE) pattern. Moreover, the resistance profiles differed in the same cluster of the upstream and the downstream sites. In flowing from the upstream to the downstream site, it is plausible that E. coli transmitted or lacked the antibiotic resistance gene.

Increased Risk

Antibiotic resistance of microorganisms is a serious health problem for both humans and animals. Infection of these bacteria may result in therapy failure, leading to high mortality rates. During an early intervention program process, the Sea Turtle Conservation Center of Thailand (STCCT) has faced high mortality rates due to bacterial infection. Previously, investigation of juvenile turtle carcasses found etiological agents in tissue lesions. Further determination of sea water in the turtle holding tanks revealed a prevalence of these causative agents in water samples, implying association of bacterial isolates in rearing water and infection in captive turtles. In this study, we examined the antibiotic resistance of bacteria in seawater from the turtle holding tank for a management plan of juvenile turtles with bacterial infection. The examination was carried out in three periods: 2015 to 2016, 2018, and 2019. The highest isolate numbers were resistant to beta-lactam, whilst low aminoglycoside resistance rates were observed. No gentamicin-resistant isolate was detected. Seventy-nine isolates (71.17%) were resistant to at least one antibiotic. Consideration of resistant bacterial and antibiotic numbers over three sampling periods indicated increased risk of antibiotic-resistant bacteria to sea turtle health. Essentially, this study emphasizes the importance of antibiotic-resistant bacterial assessment in rearing seawater for sea turtle husbandry.
