Using controlled infection experiments this study provides evidence that incorporation into marine planktonic substrates (i.e., phytoplankton cells and, to a greater extent marine aggregates) significantly promote intake of the pathogenic bacterial strain V. aestuarianus 02/041 by the Pacific oyster Crassostrea gigas maintained under stressful conditions in the laboratory resulting in a compromised health status of the infected animals.

Environmental Microbiology Reports, EarlyView. Salmonella serovars Heidelberg and Minnesota encoding antimicrobial resistance to third-generation cephalosporins and fluoroquinolones are often detected in poultry/poultry meat. We analysed the genomes of 10 Salmonella Heidelberg (SH) and 4 Salmonella Minnesota (SM) from faecal isolates of Brazilian poultry.

Environmental Microbiology Reports, EarlyView. Climate change is a global phenomenon which is affecting marine and terrestrial environments worldwide.

Environmental Microbiology Reports, EarlyView. The colonization of six edible plant species: alfalfa, broccoli, coriander, lettuce, parsley and rocket, by the human pathogen Shigatoxigenic Escherichia coli was investigated following two modes of artificial inoculation of seeds, by soaking or watering.

Environmental Microbiology Reports, EarlyView. Antibiotic resistance (AR) in bacteria is an urgent and global health issue, encompassing clinical, agricultural, terrestrial and aquatic environments. AR is not only expressed through genetic resistance. It is also found in bacteria in a small fraction of populations exhibiting antibiotic ‘persister’ states, thereby acting as a reservoir for re-growth.

Environmental Microbiology Reports, EarlyView. The epidemiology and toxigenicity of MRSA in the fishery environment are poorly understood. In this study, methicillin-resistant Staphylococcus aureus (MRSA) (n = 1) and methicillin-susceptible S. aureus (MSSA) (n = 2) from retail fish were subjected to comprehensive genome analysis. Here, we report the occurrence of ST672-MRSA-IV/t1309 and ST5-MSSA/t105 for the first time from India in the fishery environment.

Environmental Microbiology Reports, EarlyView. Summary

Environmental Microbiology Reports, EarlyView. The present study reported the antimicrobial susceptibility trends, virulence genes, and drug resistance genes of Vibrio cholerae O1 strains isolated from outbreaks and epidemics over two and half decades (1995–2019) from Odisha, India. Antimicrobial susceptibility testing was performed by disc diffusion method. Virulence and drug resistance genes were detected by multiplex PCR assays. All V.

This work aimed at studying the unconfirmed hypothesis predicting the existence of a connection between coffee farm microbiome and the resulting spontaneous fermentation process. Using Illumina‐based amplicon sequencing, 360 prokaryotes and 397 eukaryotes were identified from coffee fruits and leaves, over‐ripe fruits, water used for coffee de‐pulping, depulped coffee beans, soil, and temporal fermentation samples at an experimental farm in Honduras.

Coxiellosis or Q fever is an important global occupational zoonotic disease caused by one of the most contagious bacterial pathogens‐ Coxiella burnetii, which ranks one among the 13 global priority zoonoses. The detection of C. burnetii infection is exhibiting an increasing trend in high‐ risk personnel around the globe. It has increasingly been detected from foods of animal origin (including bulk milk, eggs, and meat) as well as tick vectors in many parts of the world.

The environmental reservoirs of different serogroups of V.cholerae causing cholera in the flowing freshwater bodies of the tribal areas of Odisha are not known. So the present study was conducted from June‐2017 to March‐2020 to find out the environmental reservoirs of V.cholerae serogroups in the water and plankton samples collected from the river, nala, stream and chua from Rayagada district.

Escherichia coli O157:H7, a causative agent of haemolytic uremic syndrome, can enter into a viable but non‐culturable (VBNC) state in response to harsh stress. Bacteria in this state can retain membrane integrity, metabolic activity and virulence expression, which may present health risks. However, virulence expression and resuscitation ability of the VBNC state are not well understood. Here, we induced E.

Antimicrobial resistance among isolates from wild animals is increasingly reported. Extended‐spectrum beta‐lactamase (ESBL)‐producing Enterobacteriaceae, and particularly Escherichia coli, have spread worldwide as one of the most common multidrug resistant organisms. The aim of this study was to determine the carriage rate of ESBL‐producing E. coli isolates and genetic characteristics in wild vultures from Canary Islands.

V. cholerae form biofilm, which is essential for their survival under harsh environmental conditions. The eDNA produced during biofilm formation and interaction with other components like vibrio polysaccharide is less studied in Vibrio cholerae despite its importance in biofilm structure and stability. In this study, we selected two strains of V. cholerae, which produced sufficient extracellular DNA in the biofilm, for characterization and studied its interaction with vibrio polysaccharide.

Vibrio cholerae O1, a natural inhabitant of estuarine environments, is found in a dormant, viable but nonculturable (VBNC) state during interepidemic periods. Although the individual roles of abiotic factors affecting VBNC formation have been extensively studied, their interplay in driving this phenomenon remains largely unaddressed. Here, we identified that major abiotic factors synergize with low nutrient conditions governing entry of cells into the VBNC state. Specifically, V.

The recent emergence of Vibrio infections at high latitudes represents a clear human health risk attributable to climate change. Here, we investigate the population dynamics of three Vibrio species: Vibrio parahaemolyticus, Vibrio vulnificus and Vibrio cholerae within a British coastal estuarine site, with contrasting salinity and temperature regimes during an intense heatwave event.

Copper is an essential element but in excess is highly toxic and therefore cytoplasmic levels must be tightly controlled. Member of the genus Burkholderia are highly resistant to various heavy metals and are often isolated from acidic soils where copper bioavailability is high. In this study, we employed transposon sequencing (Tn‐Seq) to identify copper resistance genes in Burkholderia cenocepacia H111.
