“…Was due to the survival of the fittest depending upon the antibiotics and sampling site. The resistance percentages obtained in this study tally with the resistance ranges found by other authors, Manji and Antai in 2012 [30]; Kumar and Joseph in 2011 [31]. Thus, the Enterococci show very low amoxicillin resistance rates, coinciding with the findings of Fernandes and Watanabe [26].…”

Antimicrobial resistant coliform bacteria in the Gomti river water and determination of their tolerance level

2014

The distribution of resistance to ampicillin, chloramphenicol, sulfonamides, tetracycline, and streptomycin among coliform in the Gomti river water samples was investigated. The coliform populations were isolated on Mac Conky and eosin methylene blue (EMB) agar plates supplemented with antibiotics. The incidence of resistance among the coliform population varied considerably in different drug and water sampling sites. Coliform bacteria showed lower drug resistant viable count in sampling site-III (receiving treated wastewater) as compared to more polluted site-I and site-II. Viable count of coliform population obtained on both medium was recorded higher against erythromycin from sampling site-III. Lower viable count of coliforms was recorded against tetracycline in site-II and III. Similar resistance pattern was obtained in the frequency of E. coli and Enterobacter species from all the three sampling sites. Percentage of antibiotic resistant E. coli was observed higher than Enterobacter spp among the total coliforms against all antibiotics tested without Erythromycin and penicillin in site-I and II respectively. Isolates of E. coli and Enterobacter spp. showed their tolerance level (MIC) in the range of 2-100 against the antibiotics tested. Maximum number of isolates of both genus exhibited their MICs at lower concentration range 2-5µg/ml against ciprofloxacin, tetracyclin and amoxycillin.AbbreviationsEMB - Eosin methylene blue, IMViC tests - Indole, Methyl Red, Voges Proskauer and Citrate Utilization Tests, MIC - Minimum inhibitory concentration.

“…Faecal microorganisms can enter water bodies in diverse ways, including runoff, sewage discharge, and direct faecal deposition (Korajkic et al, 2019). Many investigations have shown the presence of multi-drug resistant coliforms in water (Manji et al, 2012;Mishra et al, 2018;Kurekci et al, 2017;El-Zanfaly, 2015;Azzam et al, 2017). In water reservoirs, such as rivers, streams, lakes and retention reservoirs, both pathogenic and commensal Enterobacterales may be present (Muraleedharan et al, 2019).…”

“…Surface waters mostly contain drug-sensitive bacteria, however drug-resistant bacteria are also detected in growing amounts. Antibiotic-resistant bacteria have been detected virtually in all water bodies in the world (Manji et al, 2012;Mishra et al, 2018;Kurekci et al, 2017;El-Zanfaly, 2015;Azzam et al, 2017;Danner et al, 2019). People who use water bodies for recreational purposes constantly expose their skin and mucous membranes to bacteria which may be potentially antibiotic resistant.…”

Despite the fact that cephalosporins are rarely used in medical or veterinary treatment, the presence of Enterobacterales strains resistant to this group of anti-bacterial drugs (ESBL) is an important issue that requires attention. Between 2019 and 2021, 14 retention reservoirs, 12 streams, 3 rivers and 1 lake situated in the Tricity area (in northern Poland) were sampled for the presence of ESBL strains. Out of 40 water samples, characteristic growth (E. coli and the KESC group) on Chromagar ESBL plates was observed for 33 samples. The average number of ESBL E. coli was 42±132 CFU/100 ml, while the KESC group was 73±147 CFU/100 ml. Out of 33 positive samples, 57 ESBL Enterobacterales strains were isolated, of which the most abundant species were E. coli (13 isolates) and S. fonticola (23 isolates). The E. coli ESBL isolates not only showed resistance to third generation cephalosporins but also to antibiotics from other groups, such as fluoroquinolones, aminoglycosides and sulfonamides. The S. fonticola ESBL isolates were also found to be mainly resistant to the third generation cephalosporins, with the exception of 5 imipenem and 2 ertapenem-resistant strains. These strains presented highly diverse fingerprinting profiles, as well as significant differences in phenotypic traits helpful for survival in the environment, such as biofilm formation and motility. Moreover, biofilm formation and the swimming ability were species and temperature dependent. We confirmed the presence of highly diverse ESBL strains with multiple drug resistance patterns in the Tricity water reservoirs. This could possibly pose a threat to human health and create a suitable ground for acquiring antibiotics resistance in the natural environment.

Water is a global need for the health and survival of all life forms and a habitat to some. However, approximately one billion people in developing countries do not have access to safe drinking water in which Namibia is not an exception. Rural communities of Ohangwena and Omusati regions of Namibia construct hand-dug wells as a source of water. However, these hand-dug wells are not monitored for water quality and are generally poorly constructed. In addition, these hand-dug wells are easily accessed by both humans and animals making them a potential reservoir for zoonotic bacteria partly known to aid antimicrobial resistance development, a global health concern. A metagenomics analysis targeting the 16S rRNA gene was used to detect the bacterial communities in a total of 40 hand-dug well water samples, with 20 being from the wet season and the rest from the dry season. A total of 57 bacterial pathogens were detected with a diverse of zoonotic assemblage. Analysis revealed significant differences in diversity and evenness, and no significant difference in richness of zoonotic bacterial pathogens in hand-dug wells between the wet and dry seasons (P < 0.05) with the dry season having a higher diversity and evenness compared to the wet season. The analysis showed that the hand-dug well water was not definitely safe for human and livestock consumption and their exposure to zoonotic pathogens was pronounced in the dry season.
