Screening is important in investigating antimicrobial activities of bacteria in a quest to discover new antimicrobials. Various protocols are readily available and employed by researchers worldwide studying microbiostatic and microbicidal activities of bacterial. This research therefore aims at evaluating available protocols and suggesting a standardized model. For the purpose of these research...

The antibacterial activities of five antibiotics, three brands of Ofloxacins (Obenasin, Floxavid and Drovid) and two brands of Ciprofloxacins (Uroxin and Siprosan), and five commonly used disinfectants (Lysol, Dettol, Purit, Roberts and Wex-cide) against Staphylococcus aureus, Escherichia coli, Proteus spp., Pseudomonas aeruginosa, Streptococcus spp. and Bacillus spp. were investigated. The gro...

BACKGROUND AND OBJECTIVES Staphylococcus aureus is one of the main causatives of bovine mastitis. Resistance of some strains to methicillin, can complicate the treatment of its infections. On the other hand, enterotoxin production is also important. Therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in S. aureus isolates caused bovine mastit...

Human melanoma xenografts in immune-deprived mice have been used to assess the value of the agar diffusion chamber for chemosensitivity testing. Tumor cells were treated with melphalan, Adriamycin, or methyl frans-1-(2-chloroethyl)-3-(4methylcyclohexyl)-1 -nitrosourea either as solid tumors growing in mice or as suspensions in agar in i.p. diffusion chambers. Survival of clonogenic human tumor ...

Serological relationships among human mycoplasmas as shown by complement-fixation and gel diffusion. J. Bacteriol. 85:1261-1273. 1963.-Antigenic relationships among human mycoplasmas were studied by complement-fixation and agar gel diffusion techniques. Four recogn...

A method was developed for identification of Bacillus anthracis based on elaboration of protective antigen by individual colonies and its detection by double-diffusion precipitation in agar plates.

The agar dilution method has been standardized by the CLSI for the susceptibility testing of Campylobacter species, and according to these standards, the disk diffusion method should be used only in screening for macrolide and ciprofloxacin resistance. Nevertheless, the disk diffusion test is currently widely used, since it is easy to perform in clinical microbiology laboratories. In this study...
