Klebsiella oxytoca is a gram-negative bacterium that can be found throughout the environment as well as on mucosal membranes of mammals including humans. This bacterium is responsible for a variety of infections in humans including nosocomial infections resulting in hospital outbreaks. Reptiles including snakes, tuataras, and turtles have been shown to harbor this bacterium, and previous studies have shown that pet reptiles are a potential source for dissemination of pathogenic bacteria. Green anoles (Anolis carolensis) are a common lizard found in the southeastern part of the United States...

OBJECTIVE: To examine influences on health care workers' (HCWs') capacity to deliver health care for multi- and/or extensively drug-resistant tuberculosis (MDR/XDR-TB) and human immunodeficiency virus (HIV) infection in South Africa. DESIGN: Qualitative data were collected via group and individual interviews with a purposive sample of 17 HCWs at a centralised, tertiary TB facility and analysed using grounded theory. RESULTS: Four themes were identified: 1) personal infection control practices among HCWs may be weakened by a workplace culture comprising low motivation, disparate risk perceptions and practices across workforce hierarchies, physical discomfort, and problems managing patients with treatment-induced hearing loss...

Recent studies have highlighted the fact that the enteric microbiome, the trillions of microbes that inhabit the human digestive tract, has a significant effect on health and disease. Methods for manipulating the enteric microbiome, particularly through probiotics and microbial ecosystem transplantation, have undergone some study in clinical trials. We review some of the evidence for microbiome alteration in relation to childhood disease and discuss the clinical trials that have examined the manipulation of the microbiome in an effort to prevent or treat childhood disease with a primary focus on probiotics, prebiotics, and/or synbiotics (ie, probiotics + prebiotics)...

Research describing the epidemiology of antibiotic resistant microbes is vital to the proactive development of new antimicrobial agents. In the last years, CTX-M extended-spectrum β-lactamases (ESBLs) have emerged worldwide and have replaced classical TEM and SHV-type ESBLs in many countries. CTX-M-15 is currently the most frequent, with a pandemic distribution, and its rapid spread is facilitated by incorporation of resistance genes in mobile genetic elements. The ESBL is efficacious in Gram-negative bacteria and thus closely associated with nosocomial environments, often colonizing the intestines, particularly in older and dependent patients...

Six Klebsiella pneumoniae clinical isolates resistant to various cephalosporins and cephamycins were identified in a Japanese general hospital, a tertiary care hospital, between November 2009 and April 2010. All K. pneumoniae isolates carried blaGES-4 and blaSHV-1, while 2 K. pneumoniae isolates also harbored blaCTX-M-15. The pulsed-field gel electrophoresis patterns revealed that these 6 K. pneumoniae isolates were almost identical, suggesting their clonal relatedness. Plasmid profiles and conjugation assays revealed that these blaGES-4 genes were located on similar conjugative plasmids...

BACKGROUND: Quinupristin/dalfopristin (Q/D) is a valuable alternative antibiotic to vancomycin for the treatment of multi-drug resistant Enterococcus faecium infections. However, resistance to Q/D in E. faecium clinical isolates and nosocomial dissemination of Q/D-resistant E. faecium have been reported in several countries and should be of concern. RESULTS: From January 2012 to December 2015, 911 E. faecium clinical isolates were isolated from various specimens of inpatients at the first Affiliated Hospital of Wenzhou Medical University located in Wenzhou, east China...

Carbapenem-resistant Enterobacteriaceae (CRE) are a pressing public health issue due to limited therapeutic options to treat such infections. CREs have been predominantly isolated from humans and environmental samples and they are rarely reported among companion animals. In this study we report on the isolation and plasmid characterization of carbapenemase (IMP-4) producing Salmonella enterica Typhimurium from a companion animal. Carbapenemase-producing S. enterica Typhimurium carrying blaIMP-4 was identified from a systemically unwell (index) cat and three additional cats at an animal shelter...

Elizabethkingia meningoseptica, formerly Chryseobacterium meningosepticum usually causes neonatal meningitis and is a rare cause of nosocomial meningitis in adults. E. meningoseptica is resistant to most antibiotics, and the use of inactive drugs as empirical therapy may contribute to poor outcome in many patients. Vancomycin, alone or in combination with rifampicin, has been successful in the treatment of meningitis in infants1. We present a case of E. meningoseptica meningitis in an adult who was treated initially with intravenous vancomycin and oral rifampicin, but did not respond to the treatment...

Ampicillin resistance has greatly contributed to the recent dramatic increase of a cluster of human adapted Enterococcus faecium lineages (ST17, ST18, and ST78) in hospital-based infections. Changes in the chromosomal pbp5 gene have been associated with different levels of ampicillin susceptibility, leading to protein variants (designated as PBP5 C-types to keep the nomenclature used in previous works) with diverse degrees of reduction in penicillin affinity. Our goal was to use a comparative genomics approach to evaluate the relationship between the diversity of PBP5 among E...

Infections (including sepsis, meningitis, pneumonia and tetanus) stand as a major contributor to neonatal mortality in Haiti (22%). Infants acquire bacteria that cause neonatal sepsis directly from the mother's blood, skin or vaginal tract either before or during delivery. Nosocomial and environmental pathogens introduce further risk after delivery. The absence of cohesive medical systems and methods for collecting information limits the available data in countries such as Haiti. This study seeks to add more information on the burden of severe bacterial infections and their etiology in neonates of Haiti...

Acinetobacter baumannii are gram-negative bacilli that pose a constant threat to susceptible patients because of increased resistance to multiple antibiotics and persistence in the hospital environment. After genome analysis, we discovered that A. baumannii harbor genes that share homology to an enzymatic pathway that elongates long chain fatty acids (LCFA) in fungi. Previously, 1,2,4-Triazolidine-3-thiones (T-3-Ts) were shown to inhibit hyphae production in fungi, and this same LCFA elongation pathway was implicated as the possible target...

BACKGROUND: Methicillin resistance is a serious health concern since it has spread among Staphylococcus aureus and coagulase-negative Staphylococci (CoNS) that are frequent community and nosocomial pathogens worldwide. Methicillin-resistant strains are often resistant to other classes of antibiotics, making their treatment difficult. Nigella sativa oil is known to be active against Gram-positive cocci, yet its in vitro cytotoxicity is rarely investigated, is a proper and powerful candidate for treatment of methicillin-resistant isolates...

Pseudomonas aeruginosa is the most common Gram-negative bacterium associated with nosocomial and life-threatening chronic infections in cystic fibrosis patients. This pathogen is well-known for its ability to attach to surfaces of indwelling medical devices to form biofilms, which consist of a regular array of extracellular polymers. Tenaciously bound to the surface of devices and inherently resilient to antibiotic treatment, P. aeruginosa poses a serious threat in clinical medicine and contributes to the persistence of chronic infections...

Staphylococcus aureus and Staphylococcus epidermidis are two of the most significant opportunistic human pathogens, causing medical implant and nosocomial infections worldwide. These bacteria contain surface proteins that play crucial roles in multiple biological processes. It has become apparent that they have evolved a number of unique mechanisms by which they can immobilise proteins on their surface. Notably, a conserved cell membrane-anchored enzyme, sortase A (SrtA), can catalyse the covalent attachment of precursor bacterial cell wall-attached proteins to peptidoglycan...
