The AutoMicrobic system (AMS) is capable of identifying most Enterobacteriaceae within 8 h and many glucose-nonfermenting, gram-negative bacilli after 13 h of incubation. Early preliminary results can be readily obtained from the computer as the tests incubate. Data with 1,023 bacterial isolates were reviewed to determine the relative accuracy of 4-, 6-, 8-, 10-, and 13-h identifications. All A...

Phytase-producing Klebsiella and Shigella sp. were isolated from environmental samples based on their ability to degrade phytate and the enzymes were purified and characterized. The enzymes from both sources were intracellular monomeric proteins with the molecular mass of about 40kDa. The enzymes were active in the pH range of 2.0 to 7.5 with pH optima at 5.5. The optimum in vitro temperatures ...

Aztreonam is a new monobactam antibiotic which is highly active against aerobic Gram negative bacilli. The purpose of this study is to establish the in-vitro activity of aztreonam against recent clinical isolates of aerobic Gram negative bacilli obtained from patients at the Kuala Lumpur General Hospital. Minimum inhibitory concentrations of the antibiotic against the isolates were determined u...

Biosurfactants are surface-active biomolecules produced by microorganisms that have different applications in solving many environmental problems. This study was carried out to screen biosurfactant-producing bacteria isolated from hydrocarbon-contaminated soil of Kano Metropolis, State- Nigeria. Soil samples were collected and processed. Biosurfactant-producing enumerated, characterized using c...

The main aim of the present work was to evaluate the antibacterial activity of selenium and silver biogenic nanoparticles and further characterize them. The bacterial colony isolated from coal mine sample was found to reduce selenium and silver ions to their elemental forms respectively. Under experimental conditions, the isolated bacterium was capable of synthesising these nanoparticles which ...

An investigative study was carried out to determine the bacteriological and physicochemical qualities of borehole and well water samples in Ijebu-Ode, Southwestern Nigeria. Ten water samples each of borehole and well water sources were collected within the geographical location. Physicochemical parameters were determined using standard methods. The total bacterial count was determined by pour p...

OBJECTIVE To determine the prevalent bacterial agents of neonatal meningitis and their antibiotic susceptibility in a referral intensive care unit in Assir Central Hospital, Saudi Arabia, during the years 1993-1998. METHODS Records of newborn infants with positive cerebrospinal fluid culture during the period were retrospectively studied. RESULTS There were 1473 nursery admissions, of which...

Air dried flowers of Nerium oleander and Tecoma stans have been investigated for their polyphenolics. The pigments have been found to myricetin and rutin respectively which were characterized by chromatography and spectral studies. These pigments were screened for their antibacterial and antifungal activity against different organisms. It was ascertained that the ethyl acetate fractions of flow...

No microbial data are available for rural tropical areas. Yet most people in Africa live in rural areas where the burdens of infectious diseases remain the primary cause for morbidity and mortality. A pilot study was done by culturing midstream urine from patient with dysuria (100 with Gram-negative fermentative rods), blood from patients with FUO (55/307 positive) and swabs from patients with ...
