“…Most of the bacteria ( S. aureus , E. coli , Enterobacter spp, Shigella spp, Bacillus spp, Salmonella spp and Proteus spp) isolated demonstrated multidrug resistance except Klebsiella spp and Pseudomonas spp. The prevalence of multidrug resistant E. coli (37.1% prevalence in smoked fish and 21.7% in "suya" samples) and Enterobacter spp (31.4% prevalence in smoked fish and 15.2% in "suya" samples) reported from this study, agrees with a similar observation reported by Eze et al [28]. In an assessment of "suya", frozen and dried fish, for multidrug resistant bacteria, conducted in Obollor-afor and Nsukka, Enugu State, Nigeria, Eze et al .…”

“…The public health implication of this is of great concern. This is even more glaring in the light of the transferability of these resistance traits among both pathogenic and potentially pathogenic bacteria [28]. In a study conducted by Egbebi and Seidu [3] on "suya" sold in Ado and Akure, Southwest Nigeria, bacteria, as well as molds, yeast and fungi have been reported.…”

Introduction"suya" and smoked fish are cherished food delicacies in Nigeria, but can be a source of dissemination of Multi-drug Resistant (MDR) bacteria. Moreover, there are limited studies on these MDR bacteria from Dutsin-Ma. Therefore, this study examined the bacteriological qualities and antibiogram profiles of bacteria in these foods from this area in Nigeria.MethodsTwenty samples of each of "suya" and smoked fish were collected from the study areas and microbiologically analyzed. Total viable count, coliform count, characterization and identification of bacteria were carried out by standard microbiological techniques.ResultsFindings revealed that "suya" samples possessed the highest total viable bacteria count (3.4×105 to 7.7×105 cfu/g) and coliform count (2.1×105 to 6.2×105 cfu/g). A total of 85 and 78 bacteria were isolated from "suya" and smoked fish samples respectively. E. coli (24.7% and 24.4%) was the most frequently isolated from each sample respectively. Highest (66.7%) resistance to each of cefuroxime, gentamicin, amoxillin/clavulanate and ciprofloxacin were observed among E. coli from "suya". MDR phenotypes commonly isolated was resistance to ceftazidime, cefuroxime, ampicillin, ciprofloxacin, augmentin and nitrofurantoin.ConclusionThese studies showed the presence of MDR bacteria in samples, hence, raise the need for improved production hygiene and public health awareness.

“…Although resistance rates among clinical isolates have remained low despite long-term use, silver-resistance determinants may be located on mobile genetic elements that confer resistance to multiple other antibiotics. In accordance, silver-resistant bacterial strains have been isolated from (hospital) sewage systems 20,21. Another concern is the unresolved environmental effect of the widespread application of silver.…”

BackgroundBacterial resistance against the classic antibiotics is posing an increasing challenge for the prevention and treatment of infections in health care environments. The introduction of antimicrobial nanocoatings with active ingredients provides alternative measures for active killing of microorganisms, through a preventive hygiene approach.PurposeThe purpose of this study was to investigate the antimicrobial activity of a panel of antimicrobial coatings available on the European market.MethodsA comparative, biased selection of commercially available antimicrobial coatings was tested for antimicrobial efficiency. Suppliers were contacted to deliver their coatings on glass and/or stainless steel substrates. In total, 23 coatings from eleven suppliers were received, which were investigated for their effect on the growth of Escherichia coli, using the International Organization for Standardization (ISO) 22196 protocol.ResultsThe majority of nanomaterial-containing coatings (n=13) contained nanosilver (n=12), while only one had photocatalytic TiO2 as the active particle. The differences in antimicrobial activity among all of the coatings, expressed as log reduction values, varied between 1.3 and 6.6, while the variation within the nanomaterial-based group was between 2.0 and 6.2. Although nanosilver coatings were on average very effective in reducing the number of viable bacteria after challenge, the strongest log reduction (6.6) was seen with a coating that has immobilized, covalently bound quaternary ammonium salt in its matrix. Besides these two compounds, coatings containing TiO2, poly(dimethylsiloxane), triclosan, or zinc pyrithione evoked 100% killing of E. coli.ConclusionOur findings indicate that nanosilver dominates the nanoparticle-based coatings and performs adequately. However, considering the unknowns in relation to ecotoxicological emission and effects, it needs further consideration before widespread application into different environments.

“…Wastewater treatment plants across South Africa have displayed poor bacterial pathogen removal over the years [ 1 ]. Furthermore, the current treatment regulations and guidelines mainly using common indicator organisms as a standard for monitoring drinking water and wastewater treatment processes have proven to be unreliable [ 20 , 21 ]. This is of great public concern considering that an estimated 77 % of South Africans depend on surface water for most of their domestic water needs [ 22 , 23 ].…”

Antimicrobial resistance and virulence signatures of Listeria and Aeromonas species recovered from treated wastewater effluent and receiving surface water in Durban, South Africa

BackgroundTreated wastewater effluent has been found to contain high levels of contaminants, including disease-causing bacteria such as Listeria and Aeromonas species. The aim of this study was to evaluate the antimicrobial resistance and virulence signatures of Listeria and Aeromonas spp. recovered from treated effluents of two wastewater treatment plants and receiving rivers in Durban, South Africa.MethodsA total of 100 Aeromonas spp. and 78 Listeria spp. were positively identified based on biochemical tests and PCR detection of DNA region conserved in these genera. The antimicrobial resistance profiles of the isolates were determined using Kirby Bauer disc diffusion assay. The presence of important virulence genes were detected via PCR, while other virulence determinants; protease, gelatinase and haemolysin were detected using standard assays.ResultsHighest resistance was observed against penicillin, erythromycin and nalidixic acid, with all 78 (100 %) tested Listeria spp displaying resistance, followed by ampicillin (83.33 %), trimethoprim (67.95 %), nitrofurantoin (64.10 %) and cephalosporin (60.26 %). Among Aeromonas spp., the highest resistance (100 %) was observed against ampicillin, penicillin, vancomycin, clindamycin and fusidic acid, followed by cephalosporin (82 %), and erythromycin (58 %), with 56 % of the isolates found to be resistant to naladixic acid and trimethoprim. Among Listeria spp., 26.92 % were found to contain virulence genes, with 14.10, 5.12 and 21 % harbouring the actA, plcA and iap genes, respectively. Of the 100 tested Aeromonas spp., 52 % harboured the aerolysin (aer) virulence associated gene, while lipase (lip) virulence associated gene was also detected in 68 % of the tested Aeromonas spp.ConclusionsThe presence of these organisms in effluents samples following conventional wastewater treatment is worrisome as this could lead to major environmental and human health problems. This emphasizes the need for constant evaluation of the wastewater treatment effluents to ensure compliance to set guidelines.
