Esculin hydrolysis in the enterobacteriaceae
… in differentiating the genera and species of Enterobacteriaceae has not been widely accepted, partly because of the conflicting reports in the literature and partly because of the availability of more reliable tests. Some commercial kits (MS-2, Abbott Laboratories, Dallas, Texas; Micro-Id …

Biochemical and antibiogram characteristics of certain enterobacteriaceae
This study is a continuation of the investigations of Hall (1976), Storey (1977), and Berkowitz (1978) on antimicrobial susceptibility patterns of bacteria isolated from local hospitals in Stockton, California. It extends the work of Hall (1976) on the K-E-S group to include three species of …

Using prophylactics to improve resistance against Enterobacteriaceae in chickens
… chickens serve as major reservoirs for bacterial Enterobacteriaceae pathogens like Salmonella and Escherichia coli, which can cause disease in poultry and/or humans via contamination of poultry food products. Furthermore, these Enterobacteriaceae are major reservoirs for antimicrobial resistance …

The characterisation of nickel resistance in sewage-borne enterobacteriaceae
This thesis is a continuation of experimental work conducted by Pickup el al. (1997) analysing nickel resistant bacteria isolated from effluent discharged from a sewage outfall in the Lake District, Cumbria. Its aim is to further characterise the nickel resistance determinant ftom Enterobacter …

Virulence potential of enterobacteriaceae isolated from neonatal enternal feeding tubes
… in the incidence of neonatal infections due to Enterobacteriaceae including Escherichia coli, Enterobacter, Klebsiella and Serratia spp. These are major causative agents in neonatal intensive care unit (NICU) infections. Neonates, especially those born with low birth weight (< 2000g), are fed …

Colonocyte-Derived Lactate Promotes Enterobacteriaceae Fitness During Non-Infectious Colitis
… the contribution of metabolism by members of the Enterobacteriaceae family of bacteria, a group known to commonly outgrow during intestinal inflammation. In the example of non-infectious colitis, we further explore metabolic interactions between host and microbe by manipulating host factors that …

Threat of Carbapenem Resistant Enterobacteriaceae and the Rise of Antibiotic Resistance
… resistant microbes, Carbapenem Resistant Enterobacteriaceae (CRE) are of particular concern. CRE infections have a relative mortality rate of 50% (Guh et al., 2013). While containing Carbapenem inactivating enzymes, horizontal gene transfer is a powerful force influencing virulence of CRE. …

Stress And Survival Of Enterobacteriaceae: Studies Of Dehydration Tolerance And Polymyxin Resistance
… bacteria in the environment. Here we address how Enterobacteriaceae adapt to dehydration and polymyxins. Dehydration is an environmental stress that many bacteria encounter in their ecological niches. However, the mechanisms involved in surviving dehydration are not well understood, particularly …

Extended-Spectrum Beta-Lactamase-Producing Enterobacteriaceae: Epidemiology, Risk Factors, and Duration of Carriage
… the most important family of bacteria is Enterobacteriaceae, which includes genera and species that cause well-defined diseases and also nosocomial infections. These bacteria can give rise to numerous infections such as septicaemia and urinary tract infections. It is important to combat …

Neonatal enteral feeding tube as loci for Enterobacteriaceae colonisation and risk to neonatal health
The incidence of neonatal infections caused by Enterobacteriaceae has been increasing in recent years, and they are now recognised as the predominant causative agents in neonatal intensive care unit (NICU) outbreaks. Klebsiella spp. and Serratia spp. are the most common causative pathogens, and E. …

Soft rot Enterobacteriaceae-molecular detection and biocontrol under in vitro and in vivo conditions
Destructive soft rot Pectobacteriaceae are pathogenic to a number of vegetables, fruits and ornamentals crops and cause high economic losses in the field and during storage. An increasing number of reports in recent years illustrate the losses caused by Pectobacterium and Dickeya in Europe, and a …

Molecular methods for the detection of TEM- and SHV-related beta lactamase genes in members of the Enterobacteriaceae
… plasmid mediated beta lactamases in the Enterobacteriaceae are those related to either TEM-1 or SHY-1. Although TEM-1, TEM-2 and SHY-1 do not have activity against extended spectrum beta lactams, their derivatives (TEM-3 and SHY-2 onwards) are able to confer resistance to one or more of …

Occurrence of extended –spectrum beta-lactamase-producing enterobacteriaceae and bacterial loads in dust from poultry farms in Lusaka-Zambia.
… bacterial counts was 2.599 x108 cfu/g. For Enterobacteriaceae was 2.296x108 cfu/g. 62 Positive ESBL samples occurred in 16 farms (n=29) where ESBL samples was 4.842x104cfu/g. E.Coli showed highest resistant rate amongst other isolates. All ESBL- E isolates showed 100% resistance rate to …

The Influence of ampC Expression and Penicillin Binding Protein Binding on the Variation of ß-lactam Induction Potential in Three Genera of Enterobacteriaceae
… and Serratia marcescens are members of the Enterobacteriaceae family and are significant nosocomial pathogens. These organisms encode inducible, chromosomal AmpC ß-lactamases which can cause, if overproduced, resistance to all ß-lactams except the fourth generation cephalosporins and the …
