a hand infection from a. calcoaceticus (m. polymorpha).acinetobacter calcoaceticus (mima polymorpha) is not a well known organism, and its identification can be confusing due to its variable morphology and sensitivity pattern. in a joint infection, delay in identification or appropriate treatment can result in added morbidity. an a. calcoaceticus (mima) infection in the hand seems not to have been previously reported. the present case involving a finger joint infection illustrates the pathogenicity of a. calcoaceticus (mima) and problems of treatmen ...1979477074
community-acquired acinetobacter pneumonia.acinetobacter calcoaceticus var anitratus, a nonfermentative grampnegative bacillus, has been infrequently reported as a cause of community-acquired pneumonia. in this paper we describe the course of six recent patients with community-acquired, bacteremic pneumonia due to this organism and review the six previously reported cases. our experience suggests this organism is a more common cause of community-acquired pneumonia than previously thought. acinetobacter pneumonia occurs in older persons w ...1979463916

aminoglycoside-modifying enzymes among clinical isolates of acinetobacter calcoaceticus subsp. anitratus (herellea vaginicola): explanation for high-level aminoglycoside resistance.acinetobacter calcoaceticus subsp. anitratus (herellea vaginicola) is an important cause of nosocomial infection in our hospital where a. calcoaceticus subsp. anitratus is the most frequently isolated gram-negative species resistant to one or more of the aminoglycoside antibiotics. of 167 strains tested for susceptibility to aminoglycosides, only 6 strains were found that were resistant to >/=128 mug of kanamycin per ml; all others were susceptible to </=32 mug/ml. five of these six strains were ...1979426512
acinetobacter calcoaceticus variety anitratus: an increasing nosocomial problem.acinetobacter calcoaceticus var anitratus is an increasing nosocomial problem in some institutions. duirng a recent 16-month period, we observed 15 patients with blood isolates of this organism. thirteen of these patients acquired the organism from the hospital environment. eleven of these represented real disease and concurrent growth of the organism from another site was predictive of infection (p less than 0.03). a review of laboratory records showed that there was a three-fold increase in no ...1979426000
identification of gram-negative non-fermenters and oxidase-positive fermenters by the oxi/ferm tube.since the recent introduction of the roche oxi/ferm tube to the uk two identification schemes have been developed by the manufacturer for use with the kit. we evaluated the success of these two schemes in identifying 222 predominantly culture collection strains belonging to 45 taxa of non-fermenters and nine taxa of oxidase-positive fermenters. the strains were chosen to represent all the taxa included in the two identification schemes developed by the manufacturer and we have therefore been abl ...1979372251
nosocomial respiratory tract infection and colonization with acinetobacter calcoaceticus. epidemiologic characteristics.nosocomial respiratory tract infection with acinetobacter calcoaceticus occurs frequently in many hospitals. an outbreak of respiratory tract infections in an intensive care unit provided an opportunity to study clinical and epidemiologic characteristics of such infections. retrospective studies demonstrated that a. calcoaceticus in sputum was significantly associated with endotracheal intubation (p = 0.03) and continuous positive pressure ventilation (p less than 0.02). after control measures h ...1978362918
evaluation of the api 20e system for identification of nonfermentative gram-negative bacteria.the api 20e system for enterobacteriaceae, recently broadened to include identification of nonfermentative gram-negative bacteria, was evaluated and compared with the conventional method for complete identification of 221 nonfermenters, which were well distributed into 48 species or biotypes and included organisms not listed in the api 20e data base. the results of 16 tests common to both systems were in close agreement. the api 20e system correctly identified 71 (43%) of the 165 organisms inclu ...1978353067
evaluation of the oxi/ferm tube system for identification of nonfermentative gram-negative bacilli.the oxi/ferm tube system designed for identification of oxidative-fermentative gram-negative bacteria was evaluated for identification of nonfermentative gram-negative bacilli by comparing it with the conventional system. the nine biochemical reactions used as the initial tests in the oxi/ferm tube system showed a close agreement with the same conventional reactions. however, the system was only 41% accurate to species or biotype for complete identification of 239 isolates which were well distri ...1978353066

host factor for coliphage q beta rna replication: presence in procaryotes and association with the 30s ribosomal subunit in escherichia coli.the host factor required for in vitro coliphage q beta rna replication, a heat-stable rna binding protein present in uninfected escherichia coli, has been detected by both immunological and functional tests in acinetobacter calcoaceticus, klebsiella pneumoniae, pseudomonas aeruginosa and pseudomonas putida. it was not detectable by these criteria in bacillus stearothermophilus, bacillus subtilis, caulobacter crescentus, micrococcus lysodeikticus, rhodopseudomonas capsulata or saccharomyces cerev ...1977329101
prosthetic valve endocarditis by opportunistic pathogens.the incidence of endocarditis produced by the so-called "opportunists" as a complication of prosthetic valve surgery is progressively increasing in frequency and gradually transforming the clinical picture habitually associated with this disease. we report six cases of endocarditis produced by opportunistic microorganisms (two cases by candida, and the remaining by serratia, actinobacillus, acinetobacter calcoaceticus, and bacteroides fragilis, and by corynebacterium diphtheriae) in four male an ...1977319774
origins of metabolic diversity: evolutionary divergence by sequence repetition.recurring patterns of primary structure have been observed in enzymes that mediate sequential metabolic reactions in bacteria. the enzymes, muconolactone delta-isomerase [(+)-4-hydroxy-4-carboxymethylisocrotonolactone delta(2)-delta(3)-isomerase, ec 5.3.3.4] and beta-ketoadipate enol-lactone hydrolase [4-carboxymethylbut-3-enolide(1,4)enol-lactone-hydrolase, ec 3.1.1.24], have been coselected in bacterial populations because the isomerase can confer no nutritional advantage in the absence of the ...1979291059
ecological effects of a deodorant and a plain soap upon human skin bacteria.the effects of a commercial trichlorocarbanilide-containing deodorant soap and a commercial plain soap upon the cutaneous flora of individuals were compared. using a cross-over design, 21 volunteers (10 women and 11 men) washed their forearms at least once a day with one soap for 3 weeks and then switched soaps for another 4 weeks use. by analysis of variance no significant difference in total colony counts was noted among individuals in their use of the two soaps. with the exception of individu ...1977264493
outbreak of a multiply resistant acinetobacter in a surgical intensive care unit: epidemiology and control.during january, 1976 seven patients in an sicu became colonized or infected with acinetobacter calcoaceticus (variation, anitratum) at an attack rate of 12.5 per cent. the organism showed a marked reduction in antimicrobial sensitivity from previous experience. comparison with 34 uninfected control patients indicated that intubation and continuous ventilatory assistance were significantly associated with acquiring the organism (p = 0.0154). acinetobacter was cultured from nurses' hands, ambu ada ...1978248372
the influence of changes in the environment on twitching motility.by examining medium composition and cultural conditions quantitatively it was possible to define conditions suitable to bring twitching motility about. such conditions include the use of freshly poured, relatively thick and only slightly dried plates of a dilute medium in which the agar concentration is not too high. incubation should take place in a humid atmosphere. in fact, everything points to the humidity as a factor of the utmost importance. using strains of acinetobacter calcoaceticus, it ...1975239520
nadh and nadph-viologen reductases from acinetobacter calcoaceticus.three pyridine nucleotide-dependent diaphorases have been isolated from acinetobacter calcoaceticus cells and partially characterized. two of them, with molecular weights of 165,000 and 57,000, utilize nadph as electron donor whereas the third one (mw = 57,000) is specific for nadh. oxidized viologen dyes, flavin nucleotides, dichlorophenol indophenol and ferricyanide can act with efficiency as acceptors in the reaction mediated by these diaphorases. the diaphorase activities have been character ...1979223203
