Abstract

Roundup degrading bacteria were isolated from the soil and gut of fungus cultivating termites Macrotermes michaelseni using MM7 media supplemented with the pesticide as the sole source of carbon and energy. The isolates were gram Continue reading Isolation, characterization and identification of roundup degrading bacteria from the soil and gut of Macrotermes michaelseni – IJMM

Keywords: Antifungal metabolites, Trichoderma, Biological control, Anthracnose of chili, Colletotrichum capsici.

Abstract

Antagonist activities of different Trichoderma strains were evaluated in vitro against Colletotrichum capsici, a causal agent of anthracnose fruit rot of chili. Dual culture test showed that Trichoderma strains effectively inhibited mycelia growth of the pathogen.

Keywords: Blood glucose, Garcinia kola, liver enzymes and life expectancy.

Abstract

This study evaluated the effects of acute administration of aqueous extract of Garcinia kola on daily blood glucose level and selected biochemical indices in wistar albino Rats in connection with human health. The serum liver enzymes ALT and ALP increased significantly (p<0.05) in the test animals in groups two and three, Continue reading Acute administration of aqueous extract of Garcinia kola on daily blood glucose level and selected biochemical indices in longevity wistar albino rats

Abstract
The prevalence of extended spectrum β-lactamases among 246 clinical isolates from Abia State University teaching Hospital patients was investigated. The isolates were made up of 134 Escherichia coli and 112 Klebsiella species. Antimicrobial susceptibility of the isolates was determined by the disc diffusion method. ESBL phenotypes were determined by the double disc synergy method using ceftazidime, cefotaxime, ceftriaxone and co-amoxiclav. Out of the 246 isolates, 125 (50.8%) were ESBL producers, made up of 62(50.8%) E. coli and 63 (50.4%) Klebsiella isolates. Seventeen (54.8%) of the ESBL producing E. coli isolates were from in-patients while 45 (47.9%) were from out-patients. For the ESBL positive Klebsiella spp., 14 (45.2%) and 49 (52.1%) were from in-patients and outpatients respectively. ESBL producing isolates were also found to be more prevalent among the female patients (72.8%) than among the male patients (27.2%). The isolates also expressed high rates of resistance to other classes of antibiotics tested. However, Amikacin was found to have excellent performance against the urinary isolates tested and therefore is recommended for the treatment of infections caused by Escherichia coli and Klebsiella species. This study shows high prevalence of ESBL producing E. coli and Klebsiella isolates clinical samples of patients attending the Abia State University Teaching Hospital Aba, Abia State Nigeria.

Keywords: PVY, biological control, potato.

Abstract

The study was conducted to test the activity of Pseudomonas fluorescens, Rhodotorula sp and fermented neem extract to protect potato plants against potato virusY disease development under field conditions. Infected potato tubers were soaked in P. fluorescens, Rhodotorula sp suspensions and in fermented neem extracts separately and sown in the field in completely randomized block design.
