A new method for screening microbial colonies endowed with antiviral activity is described. It is based on close contact between microbial agar cultures and agar-covered virus-infected-cell monolayers and allows the screening of large numbers of colonies in just a few months.

AIM The aim of this study was to characterize the microbial community involved in anaerobic degradation of petroleum hydrocarbon under low- and moderate-temperature conditions. METHODS AND RESULTS Sulfate-reducing enrichment cultures growing on crude oil and p-xylene were established at low and moderate temperatures. Bacterial community structures of the cultures were characterized by 16S rRN...

Background Intra-abdominal abscesses are localized collections of pus, which generally arise from a breach in the normal mucosal defense barrier that allows bacteria from gastrointestinal tract, and less commonly from the gynecologic or urinary tract, to induce inflammation, resulting in an infection. The microbiology of these abscesses is usually polymicrobial, associated with the primary dise...

The purpose of this study was to determine the prevalence of anti-microbial resistance in intubated patients in intensive care unit (ICU) of Bahonar hospital in Kerman province, Iran during the year 2008. Tracheal samples were obtained from 111 intubated patients in the ICU by broncoalveolar lavage method. Amikacin, Ceftazidim and Imipenem were used to evaluate antibiotic susceptibility. For ...

Introduction: Infective endocarditis is a rare, fatal ,with high morbidity in children, Since infective endocarditis in children was not assessed in our conditions so our study was attempted.   Material and Methods: This cross-sectional  study  include 19 patients less than 18 years old  with endocarditis   were hospitalized in the Department of Pediatric Cardiology( University of Mashhad...

Background: Cutaneous leishmaniasis is a common parasitic disease in Isfahan province. A common complication of cutaneous leishmaniasis is bacterial superinfection, which may intensify the disease and produce scarring. Objective: The aim of this study was to determine the bacterial species isolated from infected lesions of cutaneous leishmaniasis. Patients and Methods: Two hundred out of ...

Seventy-two samples from jet aircraft fuel systems were examined for microbial contamination. Ten contaminated samples yielded 43 microorganisms which were classified into nine genera of bacteria and three genera of fungi. The predominant types, comprising about 37% of the isolated cultures, were identified as Bacillus spp. The remaining cultures were distributed among 11 genera, each of which ...

Radioactive sodium sulfide was used to label the sulfide pool of rumen contents in vitro. Microbial protein synthesis was calculated from the size and rate of dilution of label in the sulfide pool, and from the radioactivity incorporated into protein together with a conversion factor specifying the nitrogen-sulfur ratio determined for microbial protein. The microbial cell yield, calculated on t...

Microbial fuel cells often produce more electrical power with mixed cultures than with pure cultures. Here, we show that a coculture of a nonexoelectrogen (Escherichia coli) and Geobacter sulfurreducens improved system performance relative to that of a pure culture of the exoelectrogen due to the consumption of oxygen leaking into the reactor.
