This salivary and enzymatic secretions-enriched material is used by bees to cover hive walls to ensure a hospital-clean environment. Propolis extracts have been used both internally and externally for thousands of years as a healing agent in traditional medicine. Its biological properties such as antibacterial, antiviral, antifungal, among other activities, have attracted the researchers interest. In laboratory tests, studies have shown broad spectrum antimicrobial activity...

Methicillin resistant Staphylococcus aureus (MRSA) pose an important problem in hospitals, nursing homes, and other health care settings. Serious infections due to these organisms currently necessitate use of non- -lactam antibacterial therapy. For this reason, accurate detection of methicillin or oxacillin resistance among staphylococci is of great importance, consequently several techniques have been applied to this task, including agar plate screening, and disk diffusion tests. There are many lab methods for detection of methicillin resistance in S.aureus. The gold standard, for...

Microbiological investigation of male partners in infertile couple can be useful to detect the male urogenital tract infection, especially asympto-matic infections. The isolation of microorganisms from seminal fluid especially of infertile men had been widely reported.It is always recommended that microbiological study of semen can be performed in asymptomatic infertile men with leukocytospermia. Aerobic and anaerobic culture of semen can detect a wide range of urogenital pathogens. Little or no attention has been paid to the role of bacterial infection of seminal fluid in asthenospermia and...
