background: flow cytometry is a rapid, sensitive, and reliable method for determination of bacterial viability. here we assayed the capability of flow cytometry to detect helicobacter pylori viable cells in both forms of spiral and coccoid. methods: viable bacteria stained with rhodamin 123 and fluoresced with laser beam of 488nm. the rate of rh123 absorption was determined in both forms of bac...

rarely, do we think of cancer as “bacterial”, such that we are often told that “cancer is not contagious” persistent bacterial infections cause persistent irritation of the host’s defense systems, which when ineffective in eradication of the infection, result in a multitude of self-destructive damages. this in some cases occurs to such severity that the resulting cellular hyper-proliferation pr...

meningitis is one of the hazardous and life threatening infections and is associated with mortality and morbidity. the aim of this study was to determine etiological agents of childhood bacterial meningitis. the culture, gram staining, agglutination and pcr assays were used to examine csf specimens from 277 patients with presumed bacterial meningitis for the occurrence of 4 most common infectio...

in this study, the antimicrobial effect of sea cucumber extract (0.5, 1 and 2%) on the microbial population of rainbow trout fillets during refrigerated storage was examined. fillets were stored for 16 days and every 4 days microbial tests (including total bacterial load, pseudomonas, enterobacteriaceae and h2s producing bacteria) were performed on the samples. results showed that there was no ...

background: p. atrosepticum is a commercially important pathogen. it causes blackleg in the field and soft rot of tubers after the harvest. this effect is due to secretion of depolymerases and other virulence factors by several mechanisms including t3ss objectives: the effect of bacterial t3ss on solanum tuberosum (s. tuberosum) varieties and its relationship with s. tuberosum resistance gene e...

Experimental gastric ulcers are rapidly colonized by various bacteria, resulting in significantly impaired healing. Epidermal growth factor (EGF) is capable of preventing bacterial colonization of the healthy intestinal mucosa. In this study, we examined the possibility that EGF accelerates gastric ulcer healing by reducing bacterial colonization of the ulcer. Gastric ulcers were induced by ser...

A detailed understanding of the influence of temperature on soil microbial activity is critical to predict future atmospheric CO2 concentrations and feedbacks to anthropogenic warming. We investigated soils exposed to 3-4 years of continuous 5 °C-warming in a field experiment in a temperate forest. We found that an index for the temperature adaptation of the microbial community, Tmin for bacter...
