| properties of human anti-lipopolysaccharide gamma globulin: specificity and protective effects. | blood donated to the natal blood transfusion service was screened by an enzyme-linked immunosorbent assay (elisa) for anti-lipopolysaccharide (anti-lps) antibodies. plasma units with high concentrations (greater than 40 micrograms/ml) of anti-lps igg were pooled and fractionated to obtain a gamma globulin (lot lg-1). the binding of lg-1 antibodies to lps prepared from 14 bacterial species and strains was found to be the highest to lps from shigella flexneri, salmonella abortus equi and salmonell ... | 1985 | 3922117 |
| [occurrence of enteritis-causing agents in private households--a pilot study]. | the increasing occurrence of infectious enteritis caused us to perform a prospective, epidemiological pilotstudy in households, in order to receive informations about the practicability of such a project and the bacteriology of food prepared at home as well. 10 families were asked to gather samples of all foodstuffs consumed during the day in separate containers and to keep them frozen at - 20 degrees c until collected by us once a week. thus we received 4.683 samples within a 6-months-period. i ... | 1985 | 3922161 |
| bactericidal properties of a new water disinfectant. | the n-chloramine compound 3-chloro-4,4-dimethyl-2-oxazolidinone (agent i) has been compared with calcium hypochlorite as to its efficacy as a bactericide for the treatment of water. the study included concentration, contact time, ph, temperature, and water quality as controlled variables. the species of bacteria tested were staphylococcus aureus, pseudomonas aeruginosa, and shigella boydii. in general, for highly pure, demand-free water, calcium hypochlorite was the more rapid disinfectant at a ... | 1985 | 3922300 |

| infections in british clinical laboratories, 1982-3. | during 1982-3, 31 specific and 12 uncharacterized infections were reported from 30 of 240 laboratories, representing 29 223 person-years of experience. thirteen cases of hepatitis included 10 of type b or non-a, non-b hepatitis of probable occupational origin (attributable incidence 34.2 per 100 000 person years) affecting haematology, biochemistry, and postmortem workers. of nine cases of tuberculosis, three were probably acquired in the laboratory (attributable incidence 10.3 per 100 000 perso ... | 1985 | 3926828 |
| evaluation of a new screening system for enteric pathogens. | the two-hour rapid sst strip (dms laboratories, inc.) was compared with our standard screening system (triple sugar iron agar, lysine iron agar, and urea) for enteric pathogens. we tested 50 stock cultures of enteric pathogens and 213 stool cultures received in the barnes hospital clinical microbiology laboratory over a two-month period. all enteric pathogens from the stock cultures and clinical specimens were identified correctly with the rapid sst system. more false-positive reactions were obs ... | 1985 | 3928238 |
| in vitro pyocin activity of pseudomonas aeruginosa strains pretreated with antibiotics. | fifty-six selected strains of pseudomonas aeruginosa belonging to 8 different pyocin types (h, i, 15, 6, pti-1, pti-2, pti-3, pti-4) were treated with subinhibitory concentrations (mic/2) of either gentamicin or carbenicillin. both treatments induced changes in pyocin patterns for all types but at different levels. the percentage of strains that retained their pyocin pattern were more or less equal in both treatments. in treated and untreated producers, the growth inhibition ability for 5 differ ... | 1985 | 3928466 |
| the in vitro activity and beta-lactamase stability of cefpirome (hr 810), a pyridine cephalosporin agent active against staphylococci, enterobacteriaceae and pseudomonas aeruginosa. | the in vitro activity of cefpirome, a new cyclopyridinium cephalosporin, was evaluated against 947 aerobic and anaerobic bacteria. cefpirome inhibited 90% of escherichia coli, klebsiella spp., citrobacter diversus, morganella morganii, proteus vulgaris, proteus mirabilis, aeromonas spp., salmonella spp., shigella spp. and haemophilus and neisseria species at less than or equal to 0.4 mg/l. it had activity comparable to that of cefotaxime, ceftizoxime, ceftazidime, aztreonam, and moxalactam again ... | 1985 | 3928497 |

| colicin e2 production and release by escherichia coli k12 and other enterobacteriaceae. | previous work has shown that escherichia coli k12 cole2+ cells undergo a form of partial lysis and exhibit increases in lysophosphatidylethanolamine (lysope) and free fatty acid content due to activation of phospholipase a when induced to produce and release colicin e2. the increase in lysope content was assumed to be essential for efficient colicin release. these same characteristics are also presented by some natural cole2+ isolates, and by other representatives of the enterobacteriaceae after ... | 1985 | 3934329 |
