Quorum sensing is known as a communication mechanism among bacteria to control gene expression such bioluminescence, pigmentation, and pathogenicity. quenching inhibition of quorum activity. In order block activity, some produced enzymes which could degrade AHL, AHL-acylase, AHL-lactonase, AHL-oxidase reductase. this study, soil were isolated screened for their These isolates divided into Strep...
background: yersinia ruckeri is the etiological agent of enteric red mouth (erm) or yersinioisis disease, one of the important bacterial diseases in the cultured salmonids. objectives: the purpose of present study was detection of gyra gene (quinolone resistance) in the y. ruckeri bacterium. methods: in this study fish were evaluated in average size 8-12 cm from six rainbow trout farms in chaha...
Abstract Background The aim of this study was to compare the performance new flow cytometer UF-5000 with UF-1000i and Gram staining for determining bacterial patterns in urine samples. Methods Women who attended our clinic symptoms suggestive urinary tract infection were enrolled study. Mid-stream samples collected gram staining, analysis cultures. Bacterial classified using (none, cocci bacter...
Genus Brachyspira,as Gram negative anaerobic bacteria, colonize in dogs intestine. The aim of the current study was to determine the prevalence of Brachyspira spp. for the first time in Iran and rapid identification of Brachyspira spp. in dogs by a new designment of a species-specific primer set for B. canis. One hundred fifty-one fecal samples were obtained ...
Background and Objective: Coetaneous leishmaniasis is a protozoan infection which is caused by different species belonging to the genous Leishmania. Cutaneous leishmania have mostly wet and secretory sores so they create suitable environment for the growth of bacteria, fungi and other microorganisms, which results in secondary infections. In this study glucose oxidase has been used for the trea...
In the present study, we sampled sea bream and bass, weighing 400-450g, for routine microbiological, hematological, macroscopical histopathological examinations. Samples were taken from seemingly healthy fish, which displayed increased feed conversion rates, signs of cold shock slow movement. Routine bacteriological analyses included basic microbiological oxidase catalase activity, Gram stainin...
Abstract Background and objectives: Helicobacter pylori is a helical gram negative bacterium with polar flagella, discovered by Warren and Marshall in 1983. Helicobacter pylori exist in the stomach mucus tissue of less than 20% of people under 30 years old, but this amount would increase up to 40% and 60% in 60- year- old people. The aim of this study was to compare three methods of culture med...
introduction vincent’s angina refers to acute necrotizing ulcerative lesions of the oral mucosal membranes and tonsils. case presentation; in this case, we report a 17-year old girl with emotional stress referred with symptoms of vincent’s angina. gram staining showed numerous fusospirochetal bacteria. with antibiotic therapy, amoxicillin and cephalexin, no clinical improvement was observed but...
SummaryBacteria of the genus Citrobacter are found in soil, water, intestinal tract animals, human clinical samples (urine, sputum, blood, wound drainage, etc.), also wastewaters and waste dumps mines. Gram-negative bacteria SR35, capable reducing sulfur sulfate ions, were isolated from dump Nadiya coal mine, Chervonograd Mining Industrial district (Lviv region, Ukraine). The work aimed to iden...
