| restriction mediated by pav2 affects the transfer of plasmids in acinetobacter calcoaceticus. | the naturally occurring plasmid pav2 restricts the entry of the p class plasmid rp4 and the w class plasmids r388 and s-a into acinetobacter calcoaceticus strain ebf65/65 from escherichia coli. the w class plasmids only transfer from e. coli into pav2-strains. plasmid rp4 is modified in the presence of pav2 such that it is no longer restricted on entry into pav2 recipients of strain ebf65/65. | 1980 | 7021765 |
| behaviour of bacteriophage mu in acinetobacter calcoaceticus ebf65/65. | transfer of rp4::mu plasmids from escherichia coli k12 to acinetobacter calcoaceticus ebf65/65 was very inefficient compared with rp4 and was only detectable to strains of ebf65/65 lacking pav2, a cryptic plasmid thought to code for a restriction/modification system. rp4::mu-derived plasmids transferred from pav2-strains of ebf65/65 back to e. coli k12 were found to carry defective prophages which had lost the ability to produce detectable phage particles. re-transfer of these defective plasmids ... | 1980 | 7021766 |
| a common source outbreak of acinetobacter pulmonary infections traced to wright respirometers. | over a 30-day period, acinetobacter calcoaceticus var. antiratus was the responsible pathogen for hospital-acquired pneumonia in 10 patients, and resulted in the colonization of the upper respiratory tract in an additional 9 patients. wright respirometers contaminated by this organism were shown to be the common source for the outbreak as indicated by the recovery of a single serotype (8j), the inability to recover acinetobacter from any other environmental source, and the demonstration that moi ... | 1980 | 6930637 |
| purification and characterization of rhodanese from acinetobacter calcoaceticus. | rhodanese (thiosulfate : cyanide sulfur transferase, ec 2,8,1,1) was found to be contitutively present as an intracellular enzyme in acinetobacter calcoaceticus. the soluble enzyme was purified 40.9-fold by a procedure which included ultracentrifugation, ethanol precipitation, cm-sephadex batchwise separation, qae-50 ion exchange chromatography, and socrose density gradient ultracentrifugation. the enxyme had a molecular weight of approximately 35000 with a ph optimum of 8-8.5. activity was subs ... | 1980 | 6931629 |

| naturally occurring plasmids in acinetobacter calcoaceticus: a p class r factor of restricted host range. | a naturally occurring transmissible plasmid, designated pav1, has been isolated in acinetobacter calcoaceticus. it specifies resistance to sulphonamides and is capable of mobilizing two non-transmissible resistance determinants for tetracycline and neomycin, respectively, within strains of a. calcoaceticus. it is incompatible with the p class r factors rp4 and r751 in a. calcoaceticus. on this basis we conclude that pav1 is a member of the p incompatibility group. however, unlike most other p gr ... | 1980 | 7365457 |
| repetitions in the nh2-terminal amino acid sequence of beta-ketoadipate enol-lactone hydrolase from pseudomonas putida. | muconolactone delta-isomerase (ec 5.3.3.4) and beta-ketoadipate enol-lactone hydrolase (ec 3.1.1.24) mediate consecutive reactions in the beta-ketoadipate pathway of bacteria. an earlier investigation (yeh, w.k., davis, g., fletcher, p., and ornston, l.n. (1978) j. biol. chem. 253, 4920-4923) revealed that the respective nh2-terminal amino acid sequences of pseudomonas putida muconolactone isomerase and acinetobacter calcoaceticus beta-ketoadipate enol-lactone hydrolase ii are evolutionarily hom ... | 1980 | 7391022 |
| evolutionary divergence of co-selected beta-ketoadipate enol-lactone hydrolases in acinetobacter calcoaceticus. | muconolactone isomerase (ec 5.3.3.4) and beta-ketoadipate enol-lactone hydrolase (ec 3.1.1.24) mediate consecutive catabolic steps in bacteria. separately inducible beta-ketoadipate enol-lactone hydrolases i and ii are formed in representatives of acinetobacter calcoaceticus. when subjected to deae-cellulose chromatography, acinetobacter enol-lactone hydrolase i displays heterogeneous behavior which, in whole or in part, appears to be due to modifications of sulfhydryl groups in the protein; the ... | 1980 | 7391023 |
| homologies in the nh2-terminal amino acid sequences of gamma-carboxymuconolactone decarboxylases and muconolactone isomerases. | gamma-carboxymuconolactone decarobxylase (ec 4.1.1.44) and muconolactone isomerase (ec 5.3.3.4) mediate chemically analogous reactions in bacteria. the enzymes are inducible, and different metabolites trigger the respective syntheses of the decarboxylases in acinetobacter calcoaceticus and pseudomonas putida. the decarobxylases share similar oligomeric structures in which identical subunits of about 13,300 daltons appear to be self-associated into hexamers. identical residues are found in 18 of ... | 1980 | 7391024 |
| pyrogenic reactions after inadvertent infusion of endotoxin during cardiac catheterizations. | in april 1976 the attack rate of chills and fever with or without falls in blood pressure increased in association with cardiac catheterizations. fevers were associated with coronary angiography and right and left heart catheterizations. blood cultures were negative, and reactions did not correlate with amounts of contrast materials infused or with procedures done by a single operator. significant numbers of acinetobacter calcoaceticus (var. anitratus) and a pseudomonas species were cultured fro ... | 1980 | 7396310 |
| gene transfer in acinetobacter calcoaceticus: fertility variants of the sex factor pav1. | the naturally occurring transmissible plasmid pav1 mediates chromosome transfer and can exhibit two distinct levels of transmissibility in acinetobacter calcoaceticus strain ebf65/65. the two states of pav1 have been arbitrarily designated pav1a (low frequency variant) and pav1b (high frequency variant). both variants have the same incompatibility and host range properties and each mobilizes two non-transmissible resistance determinants for tetracycline and neomycin. sex factor activity has been ... | 1980 | 7411116 |
| symptomatic acinetobacter calcoaceticus peritonitis. "a complication of peritoneal dialysis". | acinetobacter calcoaceticus peritonitis was seen during the course of peritoneal dialysis in two patients with end-stage kidney disease within a 3-month period. in one patient, the isolate was a. calcoaceticus varient anitratus (formerly herellea vaginicola) and in the other it was a. calcoaceticus lwoffi (formerly mima polymorpha). both were successfully treated with continuous peritoneal antibiotic lavage. | 1980 | 7440841 |
| an outbreak of acinetobacter infection associated with the use of a ventilator spirometer. | although respiratory therapy equipment is a well-known source of nosocomial infection, ventilator spirometers have not been previously implicated. we report 17 acinetobacter calcoaceticus variety anitratus infections traced to contaminated spirometers. isolates from infected patients were recovered from urine, sputum, wounds, and blood. a review of attack rates for acinetobacter was prompted by a dramatic increase in blood culture isolates. prospective surveillance of intensive care environment, ... | 1980 | 10315086 |
| naturally occurring plasmids in acinetobacter calcoaceticus: pav2, a plasmid which influences the fertility of the sex factor pav1. | acinetobacter calcoaceticus strain ebf65/65 harbours a cryptic plasmid, pav2, which has been shown by electrophoretic separation on agarose gels to have a molecular mass of approximately 13.5 megadaltons (md). transfer of the previously described sex factor pav1 (hinchliffe & vivian, 1980 a,b) from the hospital strainjc17 into strains possessing pav2 occurs only at a low frequency, whereas transfer to similar strains lacking pav2 occurs at a much higher frequency. in ebf65/65, pav1 may be presen ... | 1980 | 7264602 |
| cell surface measurements in hydrocarbon and carbohydrate fermentations. | acinetobacter calcoaceticus was grown in 11-liter batch fermentations with hexadecane or sodium citrate as the sole source of carbon. surface and interfacial tension measurements of the microbial broth indicated that surface-active compounds were being produced only during growth on the hydrocarbon substrate. contact angle measurements of an aqueous drop on a smooth lawn of cells in a hexadecane bath indicated a highly hydrophobic surface of the cells in the initial stages of the hydrocarbon fer ... | 1980 | 16345526 |
| microbial flora of in-use, display eye shadow testers and bacterial challenges of unused eye shadows. | we surveyed 15 different brands of eye shadow on display for customer use in different retail stores for microbial contamination. this was the first reported microbial surveillance of in-use eye shadow display testers in retail establishments. cultures were obtained at each retail store. sterile dacron swabs were rolled and rubbed over the entire used surface of each shadow, and each inoculum was streaked onto the surfaces of blood agar plates. of the 1,345 individual samples obtained, 67% were ... | 1981 | 7283427 |
| role of adherence in growth of acinetobacter calcoaceticus rag-1 on hexadecane. | the high affinity of acinetobacter calcoaceticus rag-1 for liquid hydrocarbons permitted the isolation of a spontaneous nonadherent mutant, mr-481. strain mr-481 exhibited no significant affinity for three test hydrocarbons, yet resembled the wild type in many properties, including production of the extracellular emulsifying agent emulsan. to study the role of adherence in growth on hydrocarbons, rag-1 and mr-481 were compared for growth on hexadecane under conditions of limited agitation and at ... | 1981 | 7287631 |
| a cluster of acinetobacter pneumonia in foundry workers. | in a 3-month period, three men who had worked for 5 to 19 years as welders or grinders of steel castings in a foundry acquired pneumonia caused by acinetobacter calcoaceticus variety anitratus serotype 7j. two of the men died, and postmortem examination showed mixed-dust pneumoconiosis with iron particles in the lungs. a calcoaceticus variety anitratus serotype 7j was isolated from the air in the foundry but the source was not found. the prevalence of antibody titers of 64 or greater to the 7j s ... | 1981 | 7305146 |

| meningitis caused by acinetobacter calcoaceticus var anitratus. a specific hazard in neurosurgical patients. | acinetobacter calcoaceticus var anitratus caused meningitis in five patients between 1968 and 1978 at two hospitals affiliated with boston university school of medicine. all patients had had head trauma or neurosurgical procedures prior to the development of meningitis. the course of the disease was relatively indolent in that fulminant disease did not occur even when initial therapy was inappropriate and bacteria persisted in csf. all five patients survived. on gram's stain of csf, a calcoaceti ... | 1981 | 7469844 |
| a comparison of the in vitro activity of cefoxitin and cephalothin against 7,312 clinical isolates. | the antibacterial activity of cefoxitin and cephalothin was tested against 7,312 clinical isolates of aerobic pathogens. cefoxitin was found to have a broad spectrum of activity. among the gram-positive cocci, 99.1% of staphylococcus aureus, 94.4% of staphylococcus epidermidis and 98.1% of streptococci group b had a minimal inhibitory concentration of 16 microgram/ml or less, while only 4.6% of enterococci were sensitive to this concentration of cefoxitin. among the gram-negative rods 94.4% of e ... | 1981 | 7249786 |
| adherence of acinetobacter calcoaceticus rag-1 to human epithelial cells and to hexadecane. | the ability of acinetobacter calcoaceticus rag-1 to adhere to human epithelial cells was investigated and compared with its ability to adhere to a test hydrocarbon (hexadecane). rag-1, a microorganism originally isolated for growth on hydrocarbon, adhered to epithelial cells when grown under conditions which promote its adherence to hexadecane; similarly, rag-1 cells adhered poorly to epithelial cells when grown under conditions which cause the cells to possess low affinity towards hexadecane. a ... | 1981 | 7263064 |
| aerobic bacterial oral flora of garter snakes: development of normal flora and pathogenic potential for snakes and humans. | garter snakes that are used for scientific laboratory studies or kept as exotic pets often become ill and die early in captivity. they may also act as reservoirs of potential human pathogens or transmit infection to man. a total of 126 strains of aerobic and facultative bacteria, most potential human and snake pathogens, were isolated from 82 garter snake oropharyngeal cultures. coagulase-negative staphylococcus species were the most common species isolated. acinetobacter calcoaceticus var. anit ... | 1981 | 7240404 |
| trimethoprim-sulfamethoxazole therapy for infective endocarditis. | a man with stenosis of the aortic valve acquired endocarditis after abdominal surgery. klebsiella pneumoniae and acinetobacter calcoaceticus were cultured from his blood. the blood cultures remained positive despite intravenous gentamicin and cephalothin to which the organisms were sensitive in vitro. ultimately, the blood was sterilized by a combination of gentamicin and trimethoprim-sulfamethoxazole taken orally. the course of the patient was complicated by cardiac arrest and pericardial tampo ... | 1981 | 7029718 |
| quinoprotein alcohol dehydrogenase from a non-methylotroph, acinetobacter calcoaceticus. | acinetobacter calcoaceticus grown on ethanol contains an nad(p)+-independent alcohol dehydrogenase which resembles methanol dehydrogenase from methylotrophic bacteria in many respects. likewise, the prosthetic group of this enzyme appears to be identical to that of methanol dehydrogenase, namely, pyrrolo quinoline quinone. the organism is unable to grow on methanol, which means that quinoprotein alcohol dehydrogenases are not restricted to methylotrophs. arguments are presented for the idea that ... | 1981 | 7033448 |
| microbial colonization of prosthetic devices. ii. scanning electron microscopy of naturally infected intravenous catheters. | forty two nonselected naturally infected intravenous catheters were investigated by scanning electron microscopy (sem) and usual bacteriological methods. in many catheter samples an amorphous deposited substance could be detected by sem investigation, mostly associated with the isolation of staphylococci, acinetobacter calcoaceticus and pseudomonas aeruginosa. the thickest layers of such a substance were found in catheters infected by coagulase-negative staphylococci. the bacteria seemed to be c ... | 1981 | 6792814 |
| bb-k 122: in vitro and in vivo activity against ocular pathogens. | bb-k 122 is a new aminoglycoside antibiotic and an analogue of amikacin. this study evaluated the in vitro and in vivo activity of bb-k 122 and gentamicin against important ocular pathogens. bb-k 122 and gentamicin demonstrated generally equivalent in vitro antibacterial activity, except that gentamicin was more active against streptococcus sp. bb-k 122 showed significant in vitro activity against important ophthalmic pathogens, including pseudomonas aeruginosa, staphylococcus aureus, acinetobac ... | 1981 | 6797791 |
