“…However the antimicrobial resistance of L. monocytogenes is not an unusual biological event. This phenomena was previously reported in different studies from samples taken from dairy farms 40 , seafood products 41 , and from ready-to-eat meat products 42 . The resistance of L. monocytogenes originates from some antimicrobial resistance genes that limit the number of the effective anti-listerial agents, as revealed from the last three references.…”

“…Gomez et al reported that 43.1% and 13.9% L. innocua strains isolated from meat products and meat-processing environments were one or two antimicrobials resistance and multidrug resistance, respectively. 43 High resistance to oxacillin, clindamycin and cefuroxime, as reported previously, may be intrinsic. However, resistance and intermediate resistance to many other antibiotics were surprising as Listeria residing in wild rodents would not face selection pressure from antibiotic use.…”

“…Oxacillin resistance has previously been associated with L. monocytogenes , L. innocua and L. welshimeri isolates from various sources, including food products, the environment, animals and humans. 17, 43 It is interesting to note that the L. fleischmannii strains studied in Bertsch et al 3 harbored a transferable transposon that confers resistance to clindamycin. It would be interesting to determine if our L. fleischmannii isolates also carry the resistance transposon.…”

Listeria is ubiquitous in a variety of environments and can be isolated from a wide range of animal hosts. Rodents are capable of carrying pathogenic bacteria in their intestines, such as Listeria, and can disseminate those pathogens into the natural environment and to where human activity occurs. In this study, we investigated the occurrence and antimicrobial susceptibility of Listeria spp. isolated from wild rodents found in natural environments in China. We collected 341 intestinal fecal samples of rodents from five different regions of China, all representing different rodent habitats. The antimicrobial susceptibility of the Listeria spp. isolates obtained were firstly assessed using the Kirby–Bauer disk diffusion method. Thirty-one samples were positive for Listeria spp., of which 11 were positive for Listeria monocytogenes and seven were positive for Listeria ivanovii. Other species identified include Listeria innocua, Listeria fleischmannii and Listeria floridensis. All Listeria spp. isolates were sensitive to the majority of the antimicrobials tested, but largely resistant to oxacillin (94.1%) and cefuroxime (70.6%). All L. monocytogenes isolates were further characterized by serotyping, multi-locus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). L. monocytogenes strains were grouped into three serotypes, five sequence types and five pulsotypes (PTs) by serotyping, MLST and PFGE, respectively. Almost half of the isolates (five of 11) belonged to serotype 1/2b, ST87 and PT1. This study determined that Listeria is carried in the intestinal tracts of wild rodents from multiple regions at a low rate, filling an epidemiological data gap on Listeria in natural environments in China.

“…The ability to grow or survive at low temperatures, low pH and low water activities makes L. monocytogenes an important hazard in foods [6]. Multi-drug resistance among Listeria monocytogenes isolated from food or the environment has also been described, which imposes an additional risk to public health [7][8][9]. However, in Bangladesh information on the occurrence and distribution of pathogenic Listeria monocytogenes as well as other Listeria spp.…”

A total of 57 samples, of which 17 were surface water samples and 40 were dairy food samples (raw milk, pasteurized milk, icecream, sweet, milk based drink like matha and borhani) were tested for the isolation of Listeria spp. Putative Listeria isolates were identified by conventional microbiological tests and Analytical Profile Index. Overall prevalence of Listeria spp. in both food and water samples were 8.77%, of which one was (1.75%) Listeria monocytogenes, 2 (3.5%) were Listeria innocua and 2 were (3.5%) Listeria welshimeri. When compared between two types of samples, water samples contained two Listeria spp. (11.76%) of which one was pathogenic Listeria monocytogenes and the other was Listeria innocua. In case of food samples, three Listeria spp. (7.5%) were isolated of which one was Listeria innocua (icecream sample) and two were Listeria welshimeri (icecream sample and raw milk). No Listeria was found in pasteurized milk, sweet, matha and borhani. Antibiotic resistance profile of the Listeria isolates showed that 60% isolates were resistant to Ampicillin and Erythromycin, 20% isolates were Sulphamethoxazole and Ciprofloxacin resistant. No resistance was observed to Chloramphenicol for any Listeria isolates.
