Enhancement of shrimp health and immunity with diets supplemented with combined probiotics: application to Vibrio parahaemolyticus infections.

Dis Aquat Organ 2020 Jun 18;140:37-46. Epub 2020 Jun 18.

Research Center of Excellence on Shrimp, Walailak University, Thasala District, Nakhonsrithammarat, 80161, Thailand.

The application of probiotics for disease control in aquaculture is now a convincing approach towards replacement of antibiotics, which can cause adverse effects in aquatic animals and humans. In this study, we combined 2 probiotics, Lactobacillus acidophilus and Saccharomyces cerevisiae, with shrimp feed to create 2 formulas (WU8 and WU9), which were fed for 10 d to juvenile shrimp Penaeus vannamei. The shrimps were then subjected to a challenge infection with Vibrio parahaemolyticus, the causative agent of acute hepatopancreas necrosis disease (AHPND). Read More

Elevated levels of VCA0117 (VasH) in response to external signals activates the type VI secretion system of Vibrio cholerae O1 El Tor A1552.

Environ Microbiol 2020 Jun 26. Epub 2020 Jun 26.

Department of Molecular Biology and 2Laboratory for Molecular Infection Medicine Sweden (MIMS), Umeå University, SE-901 87, Umeå, Sweden.

The type VI nanomachine is critical for Vibrio cholerae to establish infections and to thrive in niches co-occupied by competing bacteria. The genes for the type VI structural proteins are encoded in one large and two small auxiliary gene clusters. VCA0117 (VasH) - a σ -transcriptional activator - is strictly required for functionality of the type VI secretion system since it controls production of the structural protein Hcp. Read More

Vaccines against gastroenteritis, current progress and challenges.

Gut Microbes 2020 Nov 18;11(6):1486-1517. Epub 2020 Jun 18.

University of Illinois at Urbana-Champaign , Department of Pathobiology, Urbana, Illinois, USA.

Enteric viral and bacterial infections continue to be a leading cause of mortality and morbidity in young children in low-income and middle-income countries, the elderly, and immunocompromised individuals. Vaccines are considered an effective and practical preventive approach against the predominantly fecal-to-oral transmitted gastroenteritis particularly in the resource-limited countries or regions where implementation of sanitation systems and supply of safe drinking water are not quickly achievable. While vaccines are available for a few enteric pathogens including rotavirus and cholera, there are no vaccines licensed for many other enteric viral and bacterial pathogens. Read More

Interleukin-1 receptor-associated kinases (IRAKs) play important roles in the innate immune system of TLR (Toll-like receptor) signaling pathway. In this paper, interleukin-1 receptor-associated kinase-b (designated as McIRAK-b) and interleukin-1 receptor-associated kinase-a (named as McIRAK-a) were obtained based on the transcriptome data, the full length of McIRAK-b was 1815 bp and McIRAK-a was 3168bp, encoding 532 and 978 amino acids, respectively. BLASTp analysis and phylogenetic relationship strongly suggested that the deduced amino acid sequence of McIRAK-b had high homology with IRAK-4 and McIRAK-a was similar to IRAK-1 of other mollusks, especially at their function domains.

The global burden of cholera is increasing, with the majority (60%) of the cases occurring in sub-Saharan Africa. In Zambia, widespread cholera outbreaks have occurred since 1977, predominantly in the capital city of Lusaka. During both the 2016 and 2018 outbreaks, the Ministry of Health implemented cholera vaccination in addition to other preventative and control measures, to stop the spread and control the outbreak.

Genetic and Biochemical Characterization of VMB-1, a Novel Metallo-β-Lactamase Encoded by a Conjugative, Broad-Host Range IncC Plasmid from Vibrio spp.

Adv Biosyst 2020 Mar 29;4(3):e1900221. Epub 2020 Jan 29.

Department of Infectious Diseases and Public Health, Jockey Club College of Veterinary Medicine and Life Sciences, City University of Hong Kong, Kowloon, 999077, Hong Kong.

The increasing incidence of phenotypic resistance to carbapenems in recent years is mainly attributed to acquisition of mobile carbapenemase-encoding genetic elements by major bacterial pathogens. Here, a novel carbapenemase known as Vibrio metallo-β-lactamase 1 (VMB-1), which is encoded by a gene (bla ) located in an integron-bearing, highly transmissible IncC type plasmid, namely pVB1796, is identified and characterized, both genetically and functionally. Recovered from a foodborne Vibrio alginolyticus strain that exhibits resistance to all known β-lactam antibiotics, pVB1796 is found to possess a hybrid backbone that exhibits unique features of both type 1 and type 2 IncC elements.

(-)-α-Pinene reduces quorum sensing and Campylobacter jejuni colonization in broiler chickens.

PLoS One 2020 1;15(4):e0230423. Epub 2020 Apr 1.

Department of Food Science and Technology, Biotechnical Faculty, University of Ljubljana, Ljubljana, Slovenia.

Campylobacter jejuni is one of the most prevalent causes of bacterial gastroenteritis worldwide, and it is largely associated with consumption of contaminated poultry. Current Campylobacter control measures at the poultry production level remain insufficient, and hence there is the need for alternative control strategies. We evaluated the potential of the monoterpene (-)-α-pinene for control of C. Read More

Climate Change: Implications for Gastrointestinal Health and Disease.

J Clin Gastroenterol 2020 May/Jun;54(5):393-397

Colorectal Medicine and Genetics, The Royal Melbourne Hospital, University of Melbourne, Melbourne, Vic., Australia.

The earth's atmosphere has warmed by about 1°C compared with preindustrial temperature. This is producing changes in the earth's climate and weather which have implications for gastrointestinal health and disease. Climate change will exacerbate current challenges with regard to provision of adequate nutrition and access to clean water. Read More

Vibiro vulnificus hemolysin associates with gangliosides.

BMC Microbiol 2020 Mar 30;20(1):69. Epub 2020 Mar 30.

Laboratory of Veterinary Public Health, School of Veterinary Medicine and Animal Sciences, Kitasato University, Higashi 23-35-1, Towada, Aomori, 034-8628, Japan.

Background: Vibrio vulnificus hemolysin (VVH) is a pore-forming toxin secreted by Vibrio vulnificus. Cellular cholesterol was believed to be the receptor for VVH, because cholesterol could bind to VVH and preincubation with cholesterol inhibited cytotoxicity. It has been reported that specific glycans such as N-acetyl-D-galactosamine and N-acetyl-D-lactosamine bind to VVH, however, it has not been known whether these glycans could inhibit the cytotoxicity of VVH without oligomer formation.

Cholera deaths in Soho, London, 1854: Risk Terrain Modeling for epidemiological investigations.

PLoS One 2020 30;15(3):e0230725. Epub 2020 Mar 30.

Rutgers School of Criminal Justice, Rutgers University-Newark, Newark, New Jersey, United States of America.

Risk Terrain Modeling (RTM) is a spatial analysis technique used to diagnose environmental conditions that lead to hazardous outcomes. Originally developed for applications to violent crime analysis, RTM is utilized here to analyze Dr. John Snow's data from the 1854 cholera outbreak in London to demonstrate its potential value to contemporary epidemiological investigations.

Vibrio splendidus O-antigen structure: a trade-off between virulence to oysters and resistance to grazers.

Environ Microbiol 2020 Mar 26. Epub 2020 Mar 26.

IHPE, Univ Montpellier, CNRS, Ifremer, Université de Perpignan Via Domitia, Montpellier, France.

A major debate in evolutionary biology is whether virulence is maintained as an adaptive trait and/or evolves to non-virulence. In the environment, virulence traits of non-obligatory parasites are subjected to diverse selective pressures and trade-offs. Here, we focus on a population of Vibrio splendidus that displays moderate virulence for oysters. Read More

Objectives: Using a prospective research design, we evaluated the association between acquisition of diarrhoeagenic (DEC) and development of reactive arthritis (ReA) and other reactive musculoskeletal (MSK) symptoms among international travellers.

Methods: A total of 526 study participants were asked to provide pretravel and post-travel stool samples and fill in questionnaires (pretravel, post-travel and 3-week follow-up). A multiplex quantitative PCR assay was deployed to detect five DEC comprising enteroaggregative , enteropathogenic , enterotoxigenic , enterohaemorrhagic and enteroinvasive and , , , and . Read More
