Strain-specific differences in survival of Campylobacter spp. in naturally contaminated turkey feces and water.

Strain-specific differences in survival of Campylobacter spp. in naturally contaminated turkey feces and water. Appl Environ Microbiol. 2019 Sep 13;: Authors: Good L, Miller WG, Niedermeyer J, Osborne J, Siletzky RM, Carver D, Kathariou S Abstract Campylobacter jejuni and C. coli are leading causes of human foodborne illness with poultry as a major vehicle. Turkeys are frequently colonized with Campylobacter but little is known about Campylobacter survival in turkey feces, even though fecal droppings are major vehicles for Campylobacter within-flock transmission as well as for environmental dissemination. Our objective was to examine survival of Campylobacter, including different strains, in freshly-excreted feces from naturally-colonized commercial turkey flocks and in suspensions of turkey feces in water from the turkey house. Fecal and water suspensions were stored at 4°C and Campylobacter populations were enumerated on selective media at 48-h intervals. C. jejuni and C. coli isolates were characterized for resistance to a panel of antibiotics and a subset was subtyped by multilocus sequence typing. Campylobacter was recovered from feces and water for up to 16 days. Analysis of 548 isolates (218 C. jejuni and 330 C. coli) revealed that C. jejuni survived longer than C. coli in feces (p = 0.0005), while the reverse was observed in water (p

Abstract Norovirus (NoV) is the main cause of gastroenteritis outbreaks worldwide. Although NoV spreads mainly from person to person, it is estimated that a large proportion of NoV outbreaks are caused by foodborne transmission. Bivalve mollusks are one of the most important foods involved in NoV transmission to humans. Little is known about NoV prevalence in shellfish harvested and commercialized in Brazil. The aim of this study was to map, for the first time, the distribution of NoV contamination in oysters and mussels harvested and commercialized in the coast of Pernambuco state, northeast Brazil. A total of 38...

Authors: Caselli E, Purificato I Abstract Healthcare-associated infections (HAI) affect every year about 4 million hospitalized patients in the EU, causing over 33 000 deaths as a direct consequence and over 1.1 billion € associated costs. Besides the persistent microbial contamination of the hospital environment, a major cause is the rampant antimicrobial resistance (AMR) of the HAI-associated pathogens. The hospital environment itself is in fact a reservoir of resistant pathogens, apparently not sufficiently controlled by conventional chemical-based sanitation. A recently published study, the SAN-ICA study, ...
