Abstract Vibrio cholerae , which causes the diarrheal disease cholera, is a species of bacteria commonly found in aquatic habitats. Within such environments, bacterium must defend itself against predatory protozoan grazers. Amoebae are prominent grazers, with Acanthamoeba castellanii being one best-studied amoebae. We previously showed that V. resists digestion by A. and establishes replication niche within host’s osmoregulatory organelle. In this study, we decipher molecular mechanisms...
Summary Vibrio cholerae isolates responsible for cholera pandemics represent only a small portion of the diverse strains belonging to this species. Indeed, most V. are encountered in aquatic environments. To better understand emergence pandemic lineages, it is crucial discern what differentiates from their environmental relatives. Here, we studied interaction with eukaryotic predators or competing bacteria and tested contributions haemolysin type VI secretion system (T6SS) those...
Abstract Vibrio cholerae is a well-studied human pathogen that also common inhabitant of marine habitats. In both environments, the bacterium subject to interbacterial competition. A molecular nanomachine often involved in such competitive behavior type VI secretion system (T6SS). Interestingly and contrast non-pandemic or environmental isolates, T6SS O1 El Tor clade V. cholerae, which responsible for ongoing 7th cholera pandemic, largely silent under standard laboratory culture conditions....
The bacterium Vibrio cholerae exhibits two distinct lifestyles, one as an aquatic and the other etiological agent of pandemic human disease cholera. Here, we report closed genome sequences seventh V. O1 El Tor strains, A1552 N16961, environmental strain Sa5Y.
The screening of Bacillus thuringiensis (Bt) Cry proteins with high potential to control insect pests has been the goal numerous research groups. In this study, we evaluated six monogenic Bt strains (Bt dendrolimus HD-37, kurstaki HD-1, HD-73, 4412, NRD-12 and entomocidus 60.5, which codify cry1Aa, cry1Ab, cry1Ac, cry1Ba, cry1C, cry2A genes respectively) as insecticides for most important irrigated rice: Spodoptera frugiperda, Diatraea saccharalis, Oryzophagus oryzae, Oebalus poecilus...
ABSTRACT Vibrio cholerae has caused seven cholera pandemics in the past two centuries. The seventh and ongoing pandemic been particularly severe on African continent. Here, we report long read-based genome sequences of six V. strains isolated Democratic Republic Congo between 2009 2012.
Members of the bacterial species Vibrio cholerae are known both as prominent constituents marine environments and causative agents cholera, a severe diarrheal disease. While strains responsible for cholera have been extensively studied over past century, less is about their environmental counterparts, despite contributions to species' pangenome. This study analyzed genome compositions 46 V. strains, encompassing pandemic non-pandemic, toxigenic, variants, explore diversity mobile genetic...
Infections by the endosymbiotic bacterium Wolbachia developed a rapid global expansion within Old World Drosophila species, ultimately infecting also Neotropical species. In this sense, screenings are necessary to characterize new variants of or hosts, and in order map dynamics already known infections. paper, we performed double screening approach that combined Dot-blot PCR techniques reevaluate infection status species from willistoni subgroup Drosophila. Genomic DNA isofemale lines...
Vibrio cholerae is a pathogen that causes disease in millions of people every year by colonizing the small intestine and then secreting potent cholera toxin. How overcomes colonization barrier created host’s natural microbiota is, however, still not well understood. In this context, type VI secretion system (T6SS) has gained considerable attention given its ability to mediate interbacterial killing. Interestingly, contrast non-pandemic or environmental V. isolates, strains are causing...
