An Ehrlichia canis isolate was obtained from an naturally infected dog exhibiting clinical signs of ehrlichiosis in São Paulo Municipality, state of São Paulo, Brazil. The isolate was characterized by PCR and DNA sequencing of portions of the ehrlichial genes dsb, 16SrRNA, and p28. Partial dsb and 16S rRNA sequences were identical to three and five other E. canis strains, respectively, from dif...

extract of BP-3 strain was found to have significant inhibitory effect on the test strains viz: E.coli (MTCC 40), Staphlococcus aureus (MTCC87),Proteus vulgaris(MTCC426), and Pseudomonas aeruginosa (MTCC 424). Identification of the bacteria was carried out using biochemical tests, 16SrRNA sequencing and sequences submitted to the NCBI GenBank Maryland USA and awarded with the accession number H...

AIM We aimed for detection of bacterial DNA (bactDNA) in spontaneous bacterial peritonitis (SBP) by polymerase chain reaction (PCR) and its prognostic relevance in cirrhotic patients with culture-negative non-neutrocytic ascites (CNNNA). BACKGROUND approximately 60% of patients with spontaneous bacterial peritonitis (SBP) are ascites culture negative. PATIENTS AND METHODS Of each 77 patient...

There are still notable gaps regarding the detailed distribution of microorganisms between and within insular habitats such as deep-sea hydrothermal vents. This study investigates the community composition of black smoker vent microorganisms in the Southern Hemisphere, and changes thereof along a spatial and chemical gradient ranging from the vent plume to surrounding waters. We sampled two hyd...

Understanding the mechanisms of anaerobic microbial iron cycling is necessary for a full appreciation of presentday biogeochemical cycling of iron and carbon and for drawing conclusions about these cycles on the ancient Earth. Towards that end, we isolated and characterized an anaerobic nitrate-dependent Fe(II)-oxidizing bacterium from a freshwater sediment. The 16SrRNA gene sequence of the iso...

Two bacterial strains designated C9 and C11 were isolated and characterized from black tiger shrimp Penaeus monodon maintained in laboratory conditions. The shrimp exhibited tiny white spots along with clinical signs of bacterial infection, probably, due to suboptimal water quality and resulting stress. Absence of white spot syndrome virus was confirmed by PCR. Bacterial isolates obtained from ...

L. monocytogenes adherence to food-associated abiotic surfaces and the development of biofilms as one of the underlying reasons for the contamination of ready-to-eat products is well known. The over-expression of internalins that improves adherence has been noted in cells growing as attached cells or at elevated incubation temperatures. However, the role of other internalin-independent surface ...
