pasteurella multocida (p. multocida), a gram-negative facultative anaerobic bacterium, is a causative animal pathogen in porcine atrophic rhinitis and avian fowl cholera. the outer membrane of gram-negative bacteria contains of many different protein in very high copy numbers. one of the major outer membrane, the h proteins have functional as high immunogenicity and antigenicity. in this study...

PE_PGRS 33, one of about 60 PE_PGRS genes in the Mycobacterium tuberculosis genome, encodes a surface-expressed protein that may be involved in the antigenic variation of M. tuberculosis strains and evasion of the host immune system. While genetic differences between the PE_PGRS 33 genes of H37Rv and CDC 1551 have been noted, genetic variation in this gene among clinical isolates has not been e...

abstract: in order to determine genetic variability among 33 isolates of fusarium semitectum, morpho- logical and molecular studies were carried out. isolates from different paddy fields in the north of iran were separated from each other in four morphotype groups. the isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextro...

Milk samples of 100 clinically mastitic bovines (50 each from buffaloes and cows) were processed for bacterial isolation. A total of 90 bacterial isolates, including 33 of staphylococci and 57 of other bacterial species were recovered. Of the 33 staphylococcal isolates, 23 were identified as Staphylococcus aureus and 10 as Staphylococcus epidermidis. All Staphylococcus aureus isolates were posi...

background biosurfactants are surface-active compounds produced by some microorganisms. objectives in this study, we collected surface skin samples from breast of poultry (chicken, turkey, and, quail) and screened for biosurfactant-producing bacteria. we also determined the genera of cultured strains. materials and methods 33 hemolytic bacterial strains (15, 11, and 7 isolates from chicken, tur...

Invasive infections caused by filamentous fungi are a major threat for immunocompromised patients. Innate/acquired resistance to antifungal drugs might necessitate combination therapies. We assessed the potential combination of voriconazole with miltefosine, an original drug with antifungal activity against 33 clinically relevant mold isolates, including both azole-susceptible and -resistant As...

In northwestern Iran, magmatic activity occurred during three main intervals: The Cretaceous, Eocene, and Miocene-Quaternary. first two phases of are more consistent with arc-type magmatism on an active continental margin; whereas the last phase, which has calc-alkaline alkaline affinities, shows similarity to postcollisional magmatism. Magmatic belts mostly situated in northern eastern parts O...

PURPOSE The increasing prevalence of antimicrobial resistant bacteria has become a serious worldwide problem. The aim of this study was to analyze antimicrobial resistance data generated in 2009 by hospitals and commercial laboratories participating in the Korean Nationwide Surveillance of Antimicrobial Resistance program. MATERIALS AND METHODS Susceptibility data were collected from 24 hospi...

The genetic diversity of 33 Nigerian Helicobacter pylori isolates were studied using RAPD, PCR-RFLP and Southern blot analysis of ureA or ureCD gene probes. RAPD was able to distinguish the following number of isolates using the primers 3880: 5'-AAGAGCCCGT-3' (28), 3881 :5'-AACGCGCAAC-3' (33) and OPH8 :5'-GAAACACCCC-3' (25). Southern blot analysis using the ureCD probe was also able to distingu...
