Regeneration is regulated not only by chemical signals but also by physical processes, such as bioelectric gradients. How these may change in the absence of the normal gravitational and geomagnetic fields is largely unknown. Planarian flatworms were moved to the International Space Station for 5 weeks, immediately after removing their heads and tails. A control group in spring water remained on Earth. No manipulation of the planaria occurred while they were in orbit, and space-exposed worms were returned to our laboratory for analysis...

Clostridium chauvoei is a gram positive, spore building bacterium that causes blackleg, a mostly fatal disease in cattle and other ruminants. Although the disease is common, little is known on the epidemiology of blackleg. As infection occurs through the environment, the risk of blackleg might be increased in areas with a specific climate or soil type. Therefore, the objective of the present study was to identify spatial and temporal clusters in the incidence of blackleg in the province of Styria, Austria. Data were collected within the governmentally delivered blackleg control program which includes vaccination of cattle with access to known blackleg pastures and compensation for fallen stock...

Many people living in rural areas rely on privately owned wells as their primary source of drinking water. These water sources are at risk for fecal contamination of human, wildlife, and livestock origin. While traditional bacteriological testing involves culture-based methods, microbial source tracking (MST) assays present an opportunity to additionally determine the source of fecal contamination. This study investigated the main host sources of contamination in private well water samples with high levels of Escherichia coli (E...

Marine mammal brucellosis has been known for more than 20 years, but recent work suggests it is more widespread than originally thought. Brucella (B.) pinnipedialis has been isolated from pinnipeds, while B. ceti strains have been associated with cetaceans. Here we report a Brucella strain isolated from multiple lymph nodes of one bottlenose dolphin (Tursiops truncatus) during routine examination of dolphin carcasses found in the Croatian part of the northern Adriatic Sea during the summer of 2015. Classical bacteriological biotyping, PCR-based techniques (single, multiplex, PCR-RFLP) and 16S rRNA DNA sequencing were used to identify Brucella spp...

INTRODUCTION: Ground water is the ultimate and most suitable fresh water resource for human consumption in the urban areas of India. Studies regarding ground water quality have shown that the higher rate of exploration as compared to the rate of recharging, inappropriate dumping of solid, as well as liquid waste, lack of strict enforcement of law has led to the deterioration of ground water quality. The present study was thus, carried out to evaluate physicochemical, as well as a microbiological profile of tap water, and filtered water in urban areas of Patiala, Punjab...

Determining which microbial taxa are out there, where they live, and what they are doing is a driving approach in marine microbial ecology. The importance of these questions is underlined by concerted, large-scale, and global ocean sampling initiatives, for example the International Census of Marine Microbes, Ocean Sampling Day, or Tara Oceans. Given decades of effort, we know that the large majority of marine Bacteria and Archaea belong to about a dozen phyla. In addition to the classically culturable Bacteria and Archaea, at least 50 "clades," at different taxonomic depths, exist...

INTRODUCTION: Haemodialysis is one of the treatment modalities for patients suffering from end stage renal disease (ESRD). Dialysis patients are exposed to large volumes of water for production of dialysis fluids. Treated water and dialysate come in direct contact with the patient's bloodstream. Such patients suffer from abnormalities of the immune system, making them more susceptible to infections. Microbial contamination of the treated water and dialysate can lead to biofilm formation and release of endotoxins in Haemodialysis system...
