pediococcus pentosaceus bacteremia

Isolates for which the MIC was greater than or equal to 8 were considered resistant to vancomycin. This suspension was mixed with an equal portion of 2.0% low-melting-temperature agarose (NuSieve GTG Agarose; FMC BioProducts, Rockland, Maine) and then distributed into plug molds (Bio-Rad). Novobiocin could therefore be helpful for differentiation of these A case of septicaemia caused by Pediococcus pentosaceus is described. Analysis of WCPP identified all isolates since each species had a unique WCPP. endobj Pediococci are lactic acid bacteria commonly found in fermented vegetables, in dairy products, and in meat (17, 18). 25 0 obj Pediococcus spp. The ranges of MICs of vancomycin were 8 to 32 micrograms/ml for all enterococcal isolates and greater than 128 micrograms/ml for Lactobacillus and Pediococcus isolates. Intrinsically vancomycin-resistant gram-positives are usually opportunistic pathogens. Previous reports of human pediococcal infection are also reviewed. In an attempt to improve the reliability ofP. The patient was initially treated with debridement and fasciotomy of the anterior abdominal wall. Infection due to VRGPC developed in three patients: a urinary tract infection in two and peritonitis in one. Monitoring their resistance phenotypes before use of MLS antibiotics can help in successful treatment of Pediococcal infections in humans. isolates and 50% of Lactobacillus plantarum. All strains of P. acidilactici were susceptible to novobiocin, Bacteremia was considered to have been nosocomially acquired if the sample in the positive blood culture was obtained >48 h after admission and if there was no evidence of infection at the time of admission; otherwise, bacteremia was considered to be community acquired. The intent is to familiarize the reader with the various lactic species, their habitat or source, associated food, physiological characteristics, colonial morphology, biochemical characteristics, culture media (enrichment, nonselective, and selective), classic description, and taxonomy. (B) Dendrogram resulting from computer-assisted analysis of the PFGE profiles shown in panel A. P. acidilactici HM3020 was inducibly resistant to macrolide, lincosamide, and streptogramin B-type Using a plasmid preparation from strain P. acidilactici 6990, a previously erythromycin-sensitive Lactococcus lactis strain was made resistant. 1752 N St. NW Pediococci ap-pear on Gram’s stains to be arranged in tetrads (1, 2, 5, 7) and BACTEC culture of PD fluid isolated growth of Gram-positive cocci, which was confirmed as Pediococcus pentosaceus . Genomic sequence analysis of P. pentosaceus genome will help These results will help in selection of the best Pediococcus strains for use as starter cultures. GAR-936 inhibited all strains, including those resistant to other tetracyclines, at concentrations Only a few rare strains are resistant to vancomycin and they are generally not regarded as pathogens. (25 P. acidilactici, 9 P. The characteristics and antimicrobial susceptibilities of this organism are described. 1985;Gonzalez and Kunka, 1986). The rarity with which this organism causes infections and the novel treatment approach make this case an important contribution to infectious diseases literature. The scale represents the average percentage of similarity. (A) PFGE profiles of chromosomal DNA of P. pentosaceus strains after digestion with SmaI. The scale represents the average percentage of similarity. LAB not only influences the large intestine by affecting the intestinal flora but also by affecting other organs via the modulation of immunological parameters and intestinal permeability or via the production of bioactive or regulatory metabolites. strains. One maltose-positive strain (1259-87), identified as P. acidilactici by WCPP and confirmed by DNA-DNA hybridization experiments (data not shown), had typical negative reactions in all chromogenic substrates. These differences are statistically significant (P < 0.05) and indicate that P. acidilactici is more likely to be associated with bacteremia than P. pentosaceus. <>/Font<>/ProcSet[/PDF/Text]>>/Type/Page>> Phone: (202) 737-3600, Copyright © 2020 American Society for Microbiology | Privacy Policy | Website feedback, Print ISSN: 0095-1137; Online ISSN: 1098-660X, Instituto de Microbiologia, Universidade Federal do Rio de Janeiro, Rio de Janeiro 21941, Brazil, and, Division of Bacterial and Mycotic Diseases, Centers for Disease Control and Prevention, Atlanta, Georgia 30333, Phenotypic and Genotypic Characterization of, Sign In to Email Alerts with your Email Address.
