Broad Diversity of Fungi in Hospital Water.

Introduction: Some studies have reported the occurrence of microorganisms isolated from water. Considering these microorganisms, fungi are known to occur ubiquitously in the environment, including water, and some are pathogenic and may cause health problems, especially in immunocompromised individuals. The aim of this study was to identify fungi in hospital water samples and to correlate their presence with the concentration of free residual chlorine.

Wide diversity of fungal species found in wellwater for human consumption: an analytical cross-sectional study.

Background: Fungi are ubiquitous in the environment. They are able to grow in water and many of them may be opportunistic pathogens.

Objective: The aims were to identify fungi in registered wells (RWs) and nonregistered wells (NRWs) that tap into groundwater; and to correlate the results from physicochemical assays on this water (free residual chlorine and pH) with the presence of fungi.

High rates of contamination in raw kibbe from commercial establishments: predominance of Give.

is one of the major causes of gastroenteritis worldwide in both humans and animals and one of the main agents involved in foodborne disease outbreaks. In this study, 70 raw kibbe samples from different commercial establishments were analyzed for spp. The isolates were seroyped and tested for susceptibility to antimicrobial agents.

Phenotypic and genotypic profile of the antimicrobial resistance of bacterial isolates and evaluation of physical and chemical potability indicators in groundwater in Brazil.

The aquatic environment has received increasing attention regarding the evolution of bacterial resistance, either as a source of resistance genes or as a matrix for the dissemination of these genes. We evaluated the physicochemical, microbiological and antimicrobial resistance characteristics of 160 samples from alternative water well solutions. According to Ordinance 2914/2011 - MS, 44 (27.

Effectiveness of ATP bioluminescence assay for presumptive identification of microorganisms in hospital water sources.

Background: Laboratory analysis of organisms in water include arduous methods, such as the multiple tube and membrane filter. The ATP bioluminescence system, proposes a new way of measuring cellular material in water by measuring adenosine triphosphate (ATP) levels, which are expressed in relative light units (RLU). The ATP bioluminescence assay has been increasingly used to assess the microbiological safety of the hospital environment.

Salmonella Alachua: causative agent of a foodborne disease outbreak.

Objectives: The aim of this study is to report the occurrence of the first outbreak of food poisoning caused by Salmonella Alachua in Brazil, as well as the antimicrobial susceptibility and the genetic relatedness of Salmonella Alachua strains isolated from clinical and food samples.

Material And Methods: To elucidate the outbreak, an epidemiological investigation was carried out, and two samples of common food were tested--mayonnaise salad and galinhada (a traditional Brazilian dish of chicken and rice)--according to the Compendium of methods for the microbiological examination of foods. Five stool samples were tested employing classic methods for the isolation and identification of enterobacteria.
