Inducible oxacillin-hydrolyzing penicillinase in Aeromonas hydrophila isolated from fish.
An inducible penicillinase was shown to be present in a strain of Aeromonas hydrophila subsp. hydrophila isolated from freshwater fish. Enzyme induction was observed with benzylpenicillin or 6-aminopenicillanic acid, and the enzyme was cell bound. The penicillinase was purified 50-fold from a crude cell extract. The molecular weight was estimated to be 23,000 by gel filtration. The pH and tempe...
متن کاملSkin infection with Mycobacterium marinum from a tropical fish tank.
Opportunist acid-fast bacilli sometimes cause progressive indolent infections of the skin, producing nodules, granulomatous lesions, abscesses, or ulcers. Some of these mycobacteria prefer temperatures lower than 370C for growth, and minor trauma or devitalized tissue probably aid their entry and establishment. One such organism, Mycobacterium marinum (balnei), was identified as the cause of ep...
متن کاملNosocomial Infections with Aeromonas hydrophila from Leeches.
The manner in which leeches are maintained before they are used for therapy has not been studied as a factor contributing to nosocomial infections. A 5-year retrospective survey of Aeromonas hydrophila nosocomial infections at a hospital in Marseille, France, revealed infections in 5 (4.1%) of an estimated 122 patients treated with leeches in the Hand Surgery Unit and 2 (2.4%) of an estimated 8...
متن کاملPhloroglucinol derivatives from Aeromonas hydrophila.
greenhouse-grown red pine seedling, Pinus resinosa, when cultured on malt agar or potato dextrose agar (PDA) showed inhibitory activity against selected test fungi. Sensitive fungi included Ceratocystis ulmi (BUISM.) C. MOREAU, Pythium spp., Rhizoctonia solani KUHN, Cylindrocarpon sp., Fusarium oxysporum SCHLECT., and Sirococcus strobilinus PREUSS. When grown on PDA, a colorless crystalline sol...

background cystic fibrosis (cf) is a genetic disease with an autosomal recessive pattern of inheritance. cf caused by a mutation in the cystic fibrosis transmembrane conductance regulator (cftr) gene and characterized by impaired transport of chloride ions across the cell membrane. staphylococcus aureus, pseudomonas aeruginosa, and burkholderia cepacia have been identified in the cultures of re...
