Abstract:

Broad relationships among bacteria can be identified by ribosomal RNA analysis, but the resulting groups may not be easily definable by phenotypic characteristics. This is exemplified by the genus <i>Campylobacter</i>, which consists of at least three separate groups that cannot be differentiated readily by phenotypic characteristics. Examination of the type strains of all Campylobacter species (except <i>Campylobacter pylori), Wolinella recta, Wolinella curva, Bacteroides ureolyticus</i>, and <i>Bacteroides gracilis</i> revealed that sheathed flagella occur only in species of rRNA group II (

Abstract:

Pseudomonas fluorescens, Yersinia enterocolitica, and Listeria monocytogenes readily attach to both rubber and teflon surfaces. Once attached, a glycocalyx covering forms effectively protecting them from any sanitizer that passes over the surface. Therefore, sanitizers efficacy testing done in the laboratory with pure glycocalyx-free cultures could lead to false assumptions as to the sanitizer's true effectiveness under actual use conditions. Our objectives in this study were: (1) evaluate sanitizer efficacy of in use concentrations toward bacteria attached to gasket materials, (2) examine att

Abstract:

The production of acid mine drainage (AMD) is catalyzed by iron-oxidizing bacteria primarily of the species Thiobacillus ferrooxidans. By inhibiting these bacteria, the production of AMD can be greatly reduced. One compound found to be effective in the inhibition of T. ferrooxidans is nitrapyrine. N-Serve, a product of Dow Chemical, Inc., is the commercially available form of nitrapyrine. This compound has been widely used in agriculture for nitrification inhibition. The purpose of this study was to determine the effectiveness of N-Serve in reducing the production of AMD under simulated field

Surface analysis of buna-N-rubber and teflon was performed. Scanning electron microscopy was used to analyze the topography of both materials and x-ray microanalysis identified the elemental chemical composition of the polymers. Teflon was primarily a smooth surface with random irregular spots, while buna-N-rubber had a very rough topography with "caverns" and crevices spread over the surface. The x-ray microanalysis showed that there are no impurities on the surface of teflon; however, calcium, silicone and sulfur were present on the surface of buna-N-rubber.

Abstract:

The development of bio-resorbable implant materials is rapidly going on. Sterilization of those materials is inevitable to assure the hygienic requirements for critical medical devices according to the medical device directive (MDD, 93/42/EG). Biopolymer-containing biomaterials are often highly sensitive towards classical sterilization procedures like steam, ethylene oxide treatment or gamma irradiation. Supercritical CO2 (scCO2) treatment is a promising strategy for the terminal sterilization of sensitive biomaterials at low temperature. In combination with low amounts of additives scCO2 trea

Mannheimia haemolytica is an opportunistic pathogen in cattle and the main bacterial agent in bovine respiratory disease. Despite its economic importance, few studies have characterized the genetic diversity of M. haemolytica, particularly from feedlots. Three genotyping techniques (BOX-PCR, (GTG)5-PCR and PFGE) were compared to discriminate M. haemolytica and strains from the family Pasteurellaceae. PFGE was the most discriminating and repeatable, although BOX-PCR was most accurate in clustering isolates together according to species. Mannheimia haemolytica was isolated from nasal swab sample

Most bacterial infections can be correlated to contamination of consumables such as food and water.

We hypothesize that exposure to components of heat-killed Escherichia coli O157:H7 will induce genomic instability within animal cells directly and indirectly exposed to these determinants.

Recent genome sequencing of P. fluorescens SBW25 revealed the presence of hutD in the hut locus, which encodes a highly conserved hypothetical protein.

Tesis - Maestría en Salud Pública - Universidad Nacional de Córdoba. Facultad de Ciencias Médicas. Escuela de Salud Pública, 2018<br>Due to the potential danger to the public health posed by staphylococcal thermostable enterotoxins in dairy products, the need arose to investigate the potential ability to produce these toxins by different coagulase negative Staphylococcus species (CNS) isolated in bovine milk. These bacteria, which are becoming increasingly involved in herd infections, produce several virulence factors, including enterotoxins, and biofilm forming, which contributes to their per

Abstract:

Sulfate removal from sulfomucin is believed to be a rate-limiting step in sulfomucin degradation by bacteria from the digestive tract. A novel sulfomucin-desulfating enzyme has been discovered in the anaerobic bacterium, Prevotella strain RS2, which can grow on colonic mucin as its sole energy source. The enzyme, located in the periplasm, was assayed by measuring p-nitrophenol removal from the model substrate sulfate-6-N-acetylglucosamine-1-p-nitrophenol, sulfate-6-N-acetylglucosamine being the other product. This activity differs from that of sulfatases which remove the sulfate ester group fr

Abstract:

Chlamydia trachomatis is the most common sexually transmitted bacterial disease agent worldwide, and, though frequently asymptomatic, can cause extreme pathology including infertility. Chlamydial species exhibit a unique biphasic developmental cycle. Once attached to a cell surface, infectious elementary bodies (EB) are internalized within an inclusion, the membrane-bound structure in which EB transform to noninfectious, replicable reticulate bodies (RB). After multiple rounds of division, RB condense to form EB, which are released and can infect new host cells. In culture, exposure to stresso
