ABSTRACT A multidrug efflux pump designated LmrS (lincomycin resistance protein of Staphylococcus aureus ), belonging to the major facilitator superfamily (MFS) transporters, was cloned, and role in antimicrobial evaluated. The highest relative increase MIC, 16-fold, observed for linezolid tetraphenylphosphonium chloride (TPCL), followed by an 8-fold sodium dodecyl sulfate (SDS), trimethoprim, chloramphenicol. has 14 predicted membrane-spanning domains is homologous putative lincomycin...
Bacterial infections pose a serious public health concern, especially when an infectious disease has multidrug resistant causative agent. Such bacteria can compromise the clinical utility of major chemotherapeutic antimicrobial agents. Drug and harbor several distinct molecular mechanisms for resistance. agent efflux pumps represent mechanism The facilitator superfamily (MFS) is one largest groups solute transporters to date includes significant number bacterial drug pumps. We review recent...
The community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has become increasingly prevalent in both community and hospital settings. aim of this study was to determine the prevalence, molecular characteristics antibiotic resistance profiles CA-MRSA from community- hospital-associated infections a tertiary care Mangalore, India. Of 520 S. isolates, 362 were inpatients (IP) 158 outpatients (OP). One-hundred thirty-two MRSA isolates obtained 94 38 with complete clinical...
Members of the family Enterobacteriaceae include several human pathogens that can be acquired through contaminated food and water. In this study, incidence extended spectrum β-lactamase (ESBL)-producing enterobacteria was investigated in fresh seafood sold retail markets. The ESBL-positive phenotype detected 169 (78.60%) isolates, with Escherichia coli being predominant species (53), followed by Klebsiella oxytoca (27), K. pneumoniae (23). More than 90% isolates were resistant to third...
We cloned a gene, sugE, from the chromosome of Enterobacter cloacae ATCC 13047. Analysis susceptibilities sugE-containing strain (Escherichia coli KAM32/pSUGE28) and sugE-deficient E. (EcΔsugE) showed that SugE confers resistance to cetyltrimethylammonium bromide, cetylpyridinium chloride, tetraphenylphosphonium, benzalkonium ethidium sodium dodecyl sulfate. also investigated expression sugE. confirm here is an SMR family transporter as determined by observing its energy-dependent drug...
Diarrheal diseases are a major cause of morbidity and mortality in resource-limited countries. Among the bacterial pathogens, diarrheagenic E. coli (DEC) most frequently implicated cases epidemic endemic diarrhea worldwide. The objective this study was to determine prevalence DEC stool specimens from patients with acute using polymerase chain reaction (PCR).Escherichia samples were collected 115 hospitalized children adults Mangalore, coastal city, southern India. PCR amplification eae, bfp,...
All serotypes of Salmonella enterica are considered potentially pathogenic. However, the non-typhoidal (NTS) vary considerably in terms pathogenicity and severity infections. Although diverse NTS have been reported from tropical seafood, their sources, physiological characteristics, virulence potentials not well understood. This study aimed to compare characteristics selected serovars seafood investigate possible variations distribution known genes within islands.A series biochemical tests,...
The major facilitator superfamily (MFS) of proteins constitutes a large group related solute transporters found across all known living taxa organisms. the MFS contain an extremely diverse array substrates, including ions, molecules intermediary metabolism, and structurally different antimicrobial agents. First discovered over 30 years ago, represents important collection integral membrane transporters. Bacterial microorganisms expressing multidrug efflux pumps belonging to are considered...
Contamination of coastal-marine environment with multidrug-resistant Escherichia coli has resulted in such bacteria increasingly being detected the seafood chain. This study aimed to determine quinolone and colistin resistance genes extended spectrum-β-lactamase (ESBL)-producing E. from seafood. ESBL-producing isolates (n = 269) were tested for quinolones phenotypes by disk diffusion broth microdilution methods, respectively. The further PCR screened plasmid-mediated (PMQR) qnrA, qnrB, qnrS,...
