Aim: To determine the effects subjecting Bacillus subtilis to different cultural conditions will have on crude Bacitracin produced in inhibiting growth of known susceptible organisms. Method: be a bacitracin producer was isolated from soil and identified. The isolate used produce under various culture with peptone water serving as basal fermentation medium. resultant checked for its antimicrobi...

The inhibition of sporulation septation (stage II) in Bacillus megaterium was shown with penicillin, d-cycloserine, bacitracin, vancomycin, novobiocin, chloromycetin, streptomycin, mitomycin C, and nalidixic acid.

In the study of upper respiratory infections, nose and throat cultures for beta hemolytic streptococci3 are essential. Since group A streptococci are implicated in human respiratory infections more than other groups, it is important that streptococci recovered on culture be identified as belonging to group A or not. The finding of streptococci which belong to groups other than A in the nose or ...

Overvoltage distribution along the transformer winding must be uniform to certify the safety of the operation of the power transformer. Influence of the parameters variation on the impulse voltage distribution (IVD) in disk winding transformer is going to be analyzed which hasn’t been analyzed on this type of winding in the previous papers. In this research, a transformer with disk winding and ...

Clostridium perfringens is an opportunistic pathogen that can cause food poisoning in humans and various enterotoxemia in animal species. Very little is known on the biofilm of C. perfringens and its exposure to subminimal inhibitory concentrations of antimicrobials. This study was undertaken to address these issues. Most of the C. perfringens human and animal isolates tested in this study were...

antibacterial effects of honeybee propolis tested on the paenibacillus larvae larvae, cause of honeybee american foulbrood disease. after cultivation of bacterium in special medium we used of two antibacterial susceptibility tests: broth dilution susceptibility test and paper disk susceptibility test. in the b.d.s.t 0.32 milligrams/ml and higher concentrations of propolis inhibited growth of th...
