Listeria monocytogenes is a saprophytic gram-positive bacterium, and an opportunistic foodborne pathogen that can produce listeriosis in humans animals. It has evolved exceptional ability to adapt stress conditions encountered different environments, resulting ubiquitous distribution. Because some food preservation methods disinfection protocols food-processing environments cannot efficiently prevent contaminations, L. constitutes threat human health challenge safety. In the host, colonizes...
The present research work aims to elucidate kinetics and mechanisms of the inactivation Bacillus subtilis spores by a surface micro-discharge (SMD) - cold atmospheric pressure plasma (CAPP). Regarding industrial applications, was also studied for static layer biopolymer powder or film, with an air at ambient pressure. Close 4 log10 cycles were achieved when exposing on flat glass SMD-CAPP. This effect can be reached very low power density 5 mW/cm2 in 7 min exposure time. maximum level drops...
Summary Studies have shown that ruminants constitute reservoirs of Listeria monocytogenes , but little is known about the epidemiology and genetic diversity this pathogen within farms. Here we conducted a large‐scale longitudinal study to monitor spp. in 19 dairy farms during three consecutive seasons ( N = 3251 samples). L . innocua was most prevalent species, followed by detected 52.6% more frequently cattle (4.1%) sheep (4.5%) than goat (0.2%). Lineage I accounted for 69% isolates. Among...
Listeriosis is a zoonotic disease caused by Listeria monocytogenes and ivanovii. The genus currently includes 27 recognized species found throughout the environment. number of systematic studies on antimicrobial resistance in L. isolates from domestic farms using substances limited. Importantly, dairy ruminant are reservoir hypervirulent lineage I isolates, previously associated with human clinical cases. Considering that classes antibiotics used food-producing animals frequently same or...
Listeria monocytogenes is a foodborne bacterial pathogen responsible for listeriosis. Whole-genome sequencing has been extensively used in public health and food industries to characterize circulating isolates, but genomic data on isolates occurring natural environments wild animals are still scarce.
Listeria monocytogenes, a contaminant of raw milk, includes hypervirulent clonal complexes (CC) like CC1, CC4, and CC6, highly overrepresented in dairy products when compared to other food types. Whether their higher prevalence is the consequence growth advantage this remains unknown. We examined kinetics five L. monocytogenes isolates (CC1, CC9, CC121) at 37 4 °C ultra-high temperature (UHT) milk milk. At °C, hypovirulent CC9 CC121 exhibit better parameters UHT CC6 isolates. isolate...

ABSTRACT The increasing prevalence of Listeria monocytogenes infections is a public health issue. Although studies have shown that ruminants constitute reservoirs this foodborne pathogen, little known about its epidemiology and genetic diversity within ruminant farms. Here we conducted large-scale genomic epidemiologic longitudinal study spp. in dairy their environments, comprising 19 farms monitored for three consecutive seasons ( N =3251 samples). L. innocua was the most prevalent spp,...
Two species of Listeria are pathogenic, monocytogenes and ivanovii. Although studies have shown that dairy ruminants shed spp. in feces, there is little information about do not their feces but asymptomatically carry them organs. We evidence can L. ivanovii udders tonsils without fecal shedding. Whole-genome sequence contained known core genes involved virulence antibiotic resistance. This work highlights as a intra-host site colonization.
