| [a successful treatment of progressive necrotizing myositis caused by aeromonas veronii biotype sobria]. | we report a 52 year-old patient with malignant lymphoma who developed necrotizing soft tissue infection in the left lower extremity by aeromonas veronii biotype sobria during a neutropenic period after intensive chemotherapy. we decided to amputate the involved leg when signs and symptoms of necrotizing myositis were progressing despite administration of sensitive antibiotics. he survived with subsequent intensive supportive care. it is to note that even though the patient's neutrophil count is ... | 2003 | 14672014 |
| purification of antimicrobial factor from granules of channel catfish peripheral blood leucocytes. | the channel catfish (ictalurus punctatus) is extensively used in aquaculture in the southeast us and is susceptible to many bacterial infections acquired from its pond environment. research is needed to better understand the defensive response and innate immunity of channel catfish against fish pathogens like edwardsiella ictaluri and aeromonas hydrophila. the main objectives were purification and characterization of an innate antimicrobial factor isolated from catfish leucocytes that has both b ... | 2004 | 14672693 |
| the immunosuppressive effect of alpha-permethrin on indian major carp, rohu (labeo rohita ham.). | the immunosuppressive effects of bath exposure to a sub lethal concentration of the synthetic pyrethroid alpha-permethrin (3.05 x 10(-4) mg l(-1)) in the indian major carp, labeo rohita was studied after 45 days' exposure. in some groups, the effects of alpha-permethrin on non-specific defences and serum enzymes of carp were investigated after challenge with aeromonas hydrophila. several nonspecific immune responses and serum enzymes were reduced after exposure of alpha-permethrin. bactericidal ... | 2004 | 14675832 |

| in vitro inhibition of microbial flora of fish by nisin and lactoperoxidase system. | to test the antimicrobial effects of nisin and lactoperoxidase system (lp system) against sardines flora. this study is part of a programme designed to investigate the preservability of fish using these inhibitors as potential biopreservatives. | 2004 | 14687217 |
| temperature and growth-phase effects on aeromonas hydrophila survival in natural seawater microcosms: role of protein synthesis and nucleic acid content on viable but temporarily nonculturable response. | the behaviour of aeromonas hydrophila in nutrient-poor filter-sterilized seawater was investigated at 23 and 5 degrees c with respect to its growth phase. at both temperatures, the culturable a. hydrophila population declined below the detection level (0.1 c.f.u. ml(-1)) after 3-5 weeks, depending on the initial physiological state of the cells. during the first week, starved a. hydrophila cells appeared more resistant to the seawater stress at 5 degrees c than cells initially in the exponential ... | 2004 | 14702411 |
| aeromonas hydrophila and aspiration pneumonia: a diverse presentation. | although there are ever increasing reports of extraintestinal human infections caused by aeromonads, in both immunocompromised and immunocompetent patients, respiratory tract infections remain uncommon. we describe a case of aspiration pneumonia in an immunocompetent patient with multiple sclerosis, caused by a community acquired, multidrug resistant strain of aeromonas hydrophila sensitive only to meropenem. the case highlights the clinical significance of aeromonas hydrophila as a respiratory ... | 2003 | 14703621 |
| laribacter hongkongensis: a potential cause of infectious diarrhea. | in this study, we describe the isolation of laribacter hongkongensis, a recently described genus and species of bacterium, in pure culture on charcoal cefoperazone deoxycholate agar from the stool of six patients with diarrhea. three patients were residents of hong kong, and three of switzerland. in none of the stool samples obtained from these six patients was salmonella, shigella, enterohemorrhagic escherichia coli, vibrio, aeromonas, plesiomonas, or campylobacter recovered. rotavirus antigen ... | 2003 | 14711474 |
| sequence analysis of amplified dna fragments containing the region encoding the putative lipase substrate-binding domain and genotyping of aeromonas hydrophila. | dna fragments were amplified by pcr from all tested strains of aeromonas hydrophila, a. caviae, and a. sobria with primers designed based on sequence alignment of all lipase, phospholipase c, and phospholipase a1 genes and the cytotonic enterotoxin gene, all of which have been reported to have the consensus region of the putative lipase substrate-binding domain. all strains showed lipase activity, and all amplified dna fragments contained a nucleotide sequence corresponding to the substrate-bind ... | 2004 | 14711636 |
| the antimicrobial activity of extracts of the lichen cetraria aculeata and its protolichesterinic acid constituent. | in this study, the antimicrobial activity of the acetone, diethyl ether and ethanol extracts of the lichen cetraria aculeata has been investigated. the extracts were tested against twelve bacteria and eight fungi and found active against escherichia coli, staphylococcus aureus, aeromonas hydrophila, proteus vulgaris, streptococcus faecalis, bacillus cereus, bacillus subtilis, pseudomonas aeruginosa, listeria monocytogenes. no antimicrobial activity against the fungi was detected. it was determin ... | 2003 | 14713164 |
| [biochemical characterization of aeromonad strains differing in pathogenicity]. | a virulent strain of motile aeromonad (77-18) and an avirulent strain (78-16) differed in the contents of lipids and phospholipids, odd fatty acids, activity of hydrolytic enzymes, and amount of proteins with molecular weights of 47-56 kda. it is assumed that proteins with molecular weights of 47-56 kda, proteolytic enzymes active within a wide ph range, and odd fatty acids may act as pathogenicity factors. each of these compounds or their combination determines certain stage of infection. | 2003 | 14714482 |
