“…The same result were obtained with sludge dehydrated and stabilized with lime (Reinthaler et al, 2010). The treatment had eliminated the E. coli strains in the effluent, meaning that raw sewage and slaughterhouse effluents characteristics that are without treatment may play an important role in the dissemination of E. coli in the environment (Kabiru et al, 2015).…”

The aim of this study was to detect and characterize pathogenic and antibiotic resistant Escherichia coli isolated from slaughterhouse wastewater and the effluents of a municipal wastewater treatment plant (WWTP) in Dakar, Senegal. Genetic markers associated with enterohemorrhagic E. coli (EHEC) and extraintestinal pathogenic E. coli (ExPEC) were screened in 268 E. coli isolates from slaughterhouse and 272 E. coli isolates from WWTP. Concerning antimicrobial resistance, 40 E. coli isolates were studied for each of the two sampling sites. None of the E. coli isolates harboring the genes associated with EHEC was detected in WWTP. Of the 13 tested virulence genes, fuyA and f17 were the most prevalent. The pathogenic and resistant E. coli was found in the raw wastewater and the influent of slaughterhouse. The final rejection used for urban gardening, including the watering of vegetables does not contain E. coli. These results showed that, after treatment, the sanitation risks associated with the reuse water from WWTP were low.

“…Water certainly promotes the circulation of Enterobacteriaceae strains (be they resistant or not). [18][19][20][21][22][23][24][25] Moreover, access to drinking water is not properly insured in many parts of the city. As such, Enterobacteriaceae from stools can easily affect many people through contaminated water.…”

Background: In recent years, a worldwide dissemination of CTX-M beta-lactamase-type in Escherichia coli strains isolates from community-acquired urinary tract infections (CA-UTI) has been observed. However little is known on the prevalence and risk factors of this global threat in developing countries. Objective: The aim of this study was to study the prevalence and risk factors for CA-UTI in Yaoundé, Cameroon. Methods: Eighty six patients with urinary E.coli infection recruited from 10 health structures in the town of Yaoundé, Cameroon. After taking the first urine, faeces were collected from the patients for the study of the intestinal flora. The sample collection of faeces was done on a selected gel of enterobacteria resistant to third generation of cephalosporin. The molecular typing of extended-spectrum β-lactamase (ESBL) was carried out. Results: Eighty-six strains of E. coli from 86 patients were included. We found that 39 (45.3%) strains produced an extendedspectrum beta-lactamase. Among risk factors, previous use of antibiotic and the dry season were associated with the presence of an ESBL-producing strain in the urine. All ESBL were identified as CTX-M. The production of CTX-M was found to be significantly associated with resistance to fluoroquinolones, aminoglycosides and to the association of trimethoprim-sulfamethazole. Conclusions: The prevalence of CTX-M ESBL in Yaoundé, Cameroon, provides new evidence on the global dissemination of CTX-M and the extent of this phenomenon in developing countries.

“…Indeed, the role of water pollution as a major reservoir for ESBL-E dissemination has been well documented. This has been the case not only for wastewater in China (24), the Czech Republic (25), Austria (26), India (27), Brazil (28), and Congo (29) but also for many rivers or aquatic ecosystems. ESBL-E have indeed been isolated from well water in Nicaragua (30) and from diverse other aquatic environments in Switzerland (31), the United Kingdom (32), China (33), South Korea (34), Portugal (35), and Tunisia (36).…”

Trends in Human Fecal Carriage of Extended-Spectrum β-Lactamases in the Community: Toward the Globalization of CTX-M

SUMMARY In the last 10 years, extended-spectrum β-lactamase-producing enterobacteria (ESBL-E) have become one of the main challenges for antibiotic treatment of enterobacterial infections, largely because of the current CTX-M enzyme pandemic. However, most studies have focused on hospitalized patients, though today it appears that the community is strongly affected as well. We therefore decided to devote our investigation to trends in ESBL-E fecal carriage rates and comprehensively reviewed data from studies conducted on healthy populations in various parts of the world. We show that (i) community ESBL-E fecal carriage, which was unknown before the turn of the millennium, has since increased significantly everywhere, with developing countries being the most affected; (ii) intercontinental travel may have emphasized and globalized the issue; and (iii) CTX-M enzymes, especially CTX-M-15, are the dominant type of ESBL. Altogether, these results suggest that CTX-M carriage is evolving toward a global pandemic but is still insufficiently described. Only a better knowledge of its dynamics and biology will lead to further development of appropriate control measures.
