PURPOSE To determine the effects of exoproducts from the corneal pathogen Pseudomonas aeruginosa on corneal proteinases and proteins. METHODS Whole rabbit corneas were cultured in the presence or absence of broths conditioned with Pseudomonas aeruginosa, elastase, alkaline protease, and exotoxin A. Protein synthesis was assayed by adding 35S-methionine during the last 6 hours of culture. Case...

background: cutaneous reactions like pruritus and erythema are common in warm months of the year in bushehr port, persian gulf, iran due to jellyfish envenomation. this study reports isolation of the chrysaora hysoscella nematocysts and evaluating its pharmacological activities during a bloom in 2013. methods: the venom of c. hysoscella captured in jofre area in bushehr port was analyzed. the e...

Thirty-two clinical isolates of Enterococcus faecalis were screened for virulence factors. Twenty-four (75%) isolates produced hemolysin on Mueller-Hinton blood agar plates with sheep erythrocytes. However, the cell free heat-stable hemolysin was detected in all isolates (100%) of E. faecalis when grown in BHI-GA (BHI medium supplemented with 1% glucose and 0.03% L-arginine), but not in BHI bro...

Halophiles are salt loving organisms requiring about 3M5M NaCl concentration in their growth. Eleven halophilic archaea and nine bacteria were isolated from various samples from extremely high salt concentrated ecosystem from western parts of Maharashtra, India. The isolates were studied using morphological and biochemical studies. Most of the isolates were gram negative in nature. These organi...

Entomopathogenic fungi are important controllers of pest-insects populations in agricultural production systems and in natural environment. These fungi have enzymatic machinery which involve since the recognition and adherence of spores in their hosts culminating with infection and death of these insects. The main objective of this study was to analyzed extracellular enzyme production of the fu...
