The penicillin-binding proteins of Bacilli
… (PBPs) in the membranes of various species of Bacilli by dodecylsulphate/polyacrylamide gel electrophoresis followed by detection of the PBPs by fluorography has shown the presence of 3-5 such proteins depending on the species. Labelling of growing cells of Bacillus megaterium with …

Acquired Carbapenemases in Gram-Negative Bacilli in Singapore
… in carbapenem-resistance in Gram-negative bacilli in Singapore is due to the introduction of global clones of carbapenemase-producing strains with the potential to cause outbreaks. The diversity of acquired carbapenemase genes in Singapore, their distribution among different species, and …

Enumeration and discrimination of thermophilic bacilli in milk powder
… that the same cohorts of strains of thermophilic bacilli are the major contaminants regardless of source. In particular, Anoxybacillus flavithermus strain C emerges as the most commonly encountered contaminant especially in powders with a medium- to high thermophile count. Bacillus licheniformis …

Detection and characterisation of carbapenem-resistant gram-negative bacilli infections in Ghana
In Ghana, little is known about the nature and spread of carbapenemases in carbapenemresistant (CR) pathogens. The aims of the present study were to detect carbapenemase activity by using simple phenotypic tests, molecular typing to characterise the resistance genes and to determine the relatedness …

In vitro activity of cephalosporins against selected gram negative bacilli : [a thesis]
… studied against 146 strains of Gram negative bacilli belonging to the following families: Enterobacteriaceae Proteus vulgarius (2), P. mirabilis (5), Providencia stuartti (6), P. alkalifaciens (5), Morganella morganii (16), Serratia marcescens (14), Enterobacter cloacae (17), E. aerogenes (9), …

Discovery of Natural Product-based Antimycobacterial Agents Effective against Non-replicating Bacilli
<p>New antimycobacterial molecules that kill non-replicating Mycobacterium tuberculosis (Mtb) were identified by screening libraries of synthetic natural products. De novo screening of a 400-membered library of aurachin RE analogs resulted in discovery of UT-317 ((R)-20). UT-317 is a selective …

The biochemical and antibiogram characteristics of aerobic gram negative enteric bacilli, with special reference to Escherichia coli, from macaws
… bacteria, represented by six species of bacilli, isolated from ten macaws of the genus Ara. Bacterial samples were acquired from fecal matter of six different species of macaws, ages one to three years, housed in a variety of locations. Bacteria from these samples were cultured onto …

Autofocusing and image segmentation in microscopy for automatic detection of tuberculosis in sputum smears
… will automatically detect the presence of TB bacilli in Ziehl-Neelsen (ZN) stained sputum smears. The microscope consists of a digital camera, motorised stages, and will have an on-board processor containing the algorithms for autofocusing the microscope and for automatically identifying TB …

Biochemical characterizations of extracellular vesicles shed by vegetative and sporulating Bacillus subtilis
Sporulation of Bacilli is a developmental process that provides long-term viability in unfavorable environments. Recently, biogenesis of extracellular vesicles (EVs) from Bacilli has also been reported to participate in various physiological and pathogenic phenomena. In this study, EVs were …

The design and synthesis of a new lead against tuberculosis
… primarily due to the Mycobacterium tuberculosis bacilli having a complex cell wall structure, intracellular existence in the host and its ability to stay dormant for extended periods. The continual increase in drug resistance and the lack of new chemotherapeutic agents means the search for a new …

Development of a Humanized Mouse Model to Understand M.tb and HIV/M.tb Co-infection
… organized granulomas with cellular cuffing, bacilli localized to the periphery, and caseous necrosis in the center. Other important characteristics of human TB are also observed, including bronchial obstruction, foamy macrophages, lipid deposits, and cholesterol crystal formations. Human T …

Biochemical characteristics and antibiogram patterns of some gram-negative nonfermentors
… a random sample of non fermentative bacilli obtained from local hospitals and determining the prevalence of Ps. aeruginosa among them. A second objective was to compare the antibiogram patterns obtained in this study with those reported by other investigators, and thirdly to establish …

Molecular methods for the detection of TEM- and SHV-related beta lactamase genes in members of the Enterobacteriaceae
… problem. Beta lactam resistance in Gram negative bacilli is mediated predominantly by beta lactamases, enzymes able to hydrolyse the beta lactam ring. The commonest plasmid mediated beta lactamases in the Enterobacteriaceae are those related to either TEM-1 or SHY-1. Although TEM-1, TEM-2 and …
