In order to investigate the prevalence of Mannheimia haemolytica infection in cattle, nasal andnasopharyngeal swabs and blood samples were obtained from 250 cattle after slaughter at Ahvaz(southwestern Iran) abattoir. Nasal and nasopharyngeal swabs were cultured on blood agar and incubated at37°C for 24-48 h. The suspected bacterial cultures were processed for isolation of M. haemolytica follow...

Exploring the microbial biosphere has grown exponentially in recent years, although we are far from understanding its entirety. We present the "diversity census" problem of exploring all bacterial species in a large cohort of specimens, and detecting a specimen that contains each species (see Figure 1). The naive approach to this problem is to sequence each specimen, thus requiring costly sampl...

A total of 100 environmental samples were investigated for their ability to degrade 1 g/L surfactin as a substrate. Among them, two enrichment cultures, which exhibited microbial growth well degradation, selected and further investigated. After several successive cultivations, nanopore sequencing full-length 16S rRNA genes with MinIONTM was used analyze the bacterial species in cultures. Variov...

BACKGROUND Postoperative spinal wound infections are relatively common and are often associated with increased morbidity and poor long-term patient outcomes. The purposes of this study were to identify the common bacterial flora on the skin overlying the lumbar spine and evaluate the efficacy of readily available skin-preparation solutions in the elimination of bacterial pathogens from the surg...

For this study pneumonic lung tissue and tracheal swabs were collected from sheep, goat and cattle slaughtered at Elphora abattoir. From the total of 170 bacterial isolates from sheep lung tissue, 10.6% Bacillus species, 14.7% Mannheimia haemolytica and 42.4% Staphylococcus species were isolated aerobically. The tracheal cultures also indicated that 5.8% were Enterobacter species, 13% were Bibe...

background considering the high prevalence of bacterial vaginosis and its association with urinary tract infection in women and treatment of gynecologic problems occur when a high recurrence of bacterial vaginosis is often treated with antibiotics. objectives the purpose of this study was to investigate the inhibitory effect of lactobacillus reuteri on pathogenic bacteria isolated from women wi...

  Background : An accurate and prompt diagnosis of bacterial arthritis is essential for earlier treatment and a good outcome. Superantigens produced by Staph. Aureus are among the most lethal toxins. The paper objective was Identification of common bacterial antigens and S.aureus superantigens in synovial fluid (SF) of children with negative culture and direct smear for other bacteria except fo...

BACKGROUND Infectious complications are observed in 40-70% of all patients with severe acute pancreatitis. Infections are associated with a significant increase in mortality rates. METHODS We evaluated the prevalence and characteristics of pancreatic and systemic infections in 46 patients with necrotizing pancreatitis submitted to surgical procedures during their hospital stay as well as the ...

Most dinoflagellates in culture are bacterized, complicating the quantification of protein synthesis, as well as the analysis of its regulation. In bacterized cultures of Amphidinium carterae Hulbert, up to 80% of protein synthetic activity appears to be predominantly bacterial based on responses to inhibitors of protein synthesis. To circumvent this, axenic cultures of A. carterae were obtaine...
