Background. Fungal infections are a rare but important cause of morbidity and mortality in kidney transplantation. Fungal contamination of the kidney preservation fluid may, sometimes, be the cause of these infections. However, the clinical consequences of fungal contamination of this fluid are not completely understood and literature on this topic is controversial. The purpose of this study was to determine the incidence of preservation fluid contamination by fungi and its clinical consequences.
This study shows that efflux activity contributes to colistin heteroresistance in an MDR A. baumannii clinical isolate. The use of efflux inhibitors as adjuvants of the therapy can resensitize A. baumannii to colistin and prevent the emergence of drug resistance.
Staphylococcus saprophyticus
is a primary cause of community-acquired urinary tract infections (UTIs) in young women.
S. saprophyticus
colonizes humans and animals but basic features of its molecular epidemiology are undetermined. We conducted a phylogenomic analysis of 321
S. saprophyticus
isolates collected from human UTIs worldwide during 1997–2017 and 232 isolates from human UTIs and the pig-processing chain in a confined region during 2016–2017. We found epidemiologic and genomic evidence that the meat-production chain is a major source of
S. saprophyticus
causing human UTIs; human microbiota is another possible origin. Pathogenic
S. saprophyticus
belonged to 2 lineages with distinctive genetic features that are globally and locally disseminated. Pangenome-wide approaches identified a strong association between pathogenicity and antimicrobial resistance, phages, platelet binding proteins, and an increased recombination rate. Our study provides insight into the origin, transmission, and population structure of pathogenic
S. saprophyticus
and identifies putative new virulence factors.
Anisakiasis is an emerging marine food-borne zoonosis resulting from the accidental ingestion of Anisakis larvae, through the consumption of raw or undercooked infected seafood products. The first case of human gastric hyperinfection by Anisakis simplex with an unusual and severe presentation, occurring in a Portuguese woman, is described in this article. Over 140 anisakid larvae were removed by gastroscopy. Massive infection is uncommon in areas where the consumption of raw fish is not part of the traditional diet, as is the case in Portugal. The increased consumption of raw seafood products is considered a health determinant in the rise in cases of anisakiasis. However, clinicians should be aware of the emergence of these infections, not only because of the new dietary habits of the population, but also because of the high prevalence of Anisakis larvae in the different fish species usually consumed by the population, collected on the Portuguese coast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
