The purpose of this study was to investigate the occurrence of Cryptosporidium spp. and Giardia spp. in a public water-treatment system. Samples of raw and treated water were collected and concentrated using the membrane filtration technique. Direct Immunofluorescence Test was performed on the samples. DNA extraction using a commercial kit was performed and the DNA extracted was submitted to a ...

Factors implicated in the pathophysiology of ulcerative colitis (UC) are an abnormal immune response, defect in intestinal epithelial barrier function, and gut microbiota. Currently, it is unclear whether specific bacterial strains are responsible for the induction of intestinal inflammation, but increased bacterial tissue invasion has been described in affected UC patients. Further, a quantita...

The diel vertical migration (DVM) of the whole plankton community was investigated in the central and coastal Irish Sea. Generally, more than 60% of the plankton did not perform significant DVM. A correlation analysis of the weighted mean depths of different organisms and their potential predators suggested relationships between 2 groups: Oithona spp., copepod nauplii and fish larvae, and Calan...

Sweetpotato peptide (SPP) was prepared by enzyme digestion of sweetpotato protein from starch wastewater. Animal experiments assessed the effect of SPP on body weight, abdominal adipose tissue mass, serum lipids and adipocytokines. Body and liver weight and epididymal and mesenteric fat of mice fed a high-fat diet containing 0.5% or 5% SPP for 28 days were significantly lower than control mice....

OBJECTIVES The activity in vitro of terbinafine against 442 clinical isolates of several species of filamentous fungi was analysed. METHODS A broth microdilution test was carried out following the National Committee for Clinical Laboratory Standards reference method, with modifications described previously. RESULTS The geometric mean (GM) of MICs of terbinafine for non-Aspergillus fumigatus...

Reports on the microbial degradation of bile-acid conjugates have been mainly limited to observations of hydrolytic cleavage yielding free bile acids. Clostridium spp., Enterococcus spp. (Norman & Grubb, 1955), Bacteroides spp., BiJdobacteria spp. (Drasar & Hill, 1966) and species of rat intestinal bacteria (Dickinson et a/., 1971) were all shown to deconjugate bile-acid conjugates under anaero...

the aim of this study was to isolate and identify airborne fungi from locations in babol city, babolkenar forest and a beach on the caspian sea (all in north part of iran) in spring and summer. of 126 samples collected, the most clinically important isolated fungi were mucor spp. (18.6%) in the forest, alternaria spp. (13.4%) at the beach; and cladophialophora spp. (15.8%), mucor spp. (11.7%) a...

background clinical significance of extended-spectrum beta-lactamases (esbls) production in enterobacter spp. has not well been established. objectives this study was conducted to investigate the prevalence of esbls produced by enterobacter spp. in clinical isolates. materials and methods this descriptive cross-sectional study was performed during may 2010 to april 2012 in the city of sanandaj,...

Phase variation of Streptococcus gordonii between high (Spp+) and low (Spp-) levels of glucosyltransferase (GTF) activity resulted in the greater adhesion of Spp- strains to saliva-coated hydroxyapatite (S-HA) in a washed-cell adhesion test. Specific GTF mutants did not show this response. Although washed Spp+ cells produced 5-fold or more glucan from sucrose than Spp- cells did under the condi...

The objective of this study was to determine the aerobic bacteria and fungi associated with raw camel’s milk. Samples were collected from farms in Bahri (Khartoun North) area in the Sudan. The isolated aerobic bacteria (one hundred and fifteen isolates) were identified as (85.26%) Gram–negative, while (14.73%) were Gram-positive. The Gram-negative bacteria were 39.13% Escherichia coli serotypes...
