Abstract: Bacteria producing extended-spectrum ?-lactamase (ESBL) among clinical isolates have been reported in many countries. However, data concerning the role of environmental contamination in the dissemination of (ESBL)-producing Enterobactericeae are currently lacking. In this context, the aim of this study was investigate and characterize Enterobacteriacea strains isolated from different places in a hospital and to determine the occurrence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. The bacterial isolates were identified on the basis of standard cultural, morphological and biochemical characteristics. Antibiotic susceptibility of the isolates was tested by disk diffusion method. A total of 637 strains of Enterobacteriaceae were isolated between 2007-2012. Susceptibility study showed that the imipenem was the most active antibiotic against overall enterobacteria with resistance rate of 2.51 %, however the high resistance rates were observed to ampicilin (98.11 %) and cephalixin (78.65%). The prevalence of ESBL was 136 (21.35 %) and ESBL-producing strains were K.pneumoniae 66 (28.45%) E.coli 31 (25.41 %), S.marcescens 18 (19.15 %), K. oxytoca 9 (17.31 %), En.clocae 5 (5.43 %), C.freundii 04 (16 %) and P. mirabilis 03 (15 %). ESBL production was confirmed by double disk screening, combination disk method and E-test ESBL strip. All selected isolates harbored from one to four different plasmids with molecular sizes ranging from 5-170 kb. In general, most transconjugants acquired ceftazidime resistance by an ESBL gene encoded on the largest plasmid (>125 kb) found in the respective isolate. In addition, these transconjugants co-expressd other antibiotic resistance markers such as amikacin and ciprofloxacin.

Abstract: Earthworms are soil dwellers that have profound effects on soil ecosystem. Their feeding and burrowing activities help to incorporate soil particles with organic matter and redistribute them back into the soil through their casts. The casts produced enhance microbial activities in soil that promote nutrient cycling. This study was carried out to compare the population and distribution of aerobic cellulolytic bacteria in earthworm casts against surrounding soils across selected sites within the Imo State University main Campus, Owerri. Four Habitats (A, B, C and D) were selected, composite soil and cast samples were then collected and the level of cast production (gm-2) was determined. After analyzing some physicochemical properties of the samples, the total number of aerobic bacteria (in nutrient agar medium) and aerobic cellulolytic bacteria in (cellulose agar medium) were counted. Our results showed a higher casts production in Habitat A (15.30 ? 3.10 g-2) than in Habitat B(12.50 ? 3.60 g-2), followed by Habitat C (10.80 ? 4.20 g-2) and Habitat D (9.50 ? 2.30 g-2), respectively. Casts recorded higher pH values, moisture, organic matter, total N, P, K and Ca contents in all the study sites. Casts also exhibited higher number of total aerobic bacteria (TAB) and aerobic cellulolytic bacteria (ACB), and bacteria cellulolytic activity compared to the surrounding soils in all the study sites. However, the quality of cast (and soil) decreased across the study sites (from Habitat A to D). The study suggested that earthworm cast could improve the physicochemical as well as microbiological properties of soil.

Abstract: Studies were carried out on the occurrence of superficial fungal infections amongst some occupational groups in Nigeria. The occupational groups investigated included car-washers, dog breeders, local farmers, football players, hair-dressers and urban road-cleaners. The study was also extended to HIV/ AIDS patients. A total number of 13 species of fungi were isolated from both the occupational groups and the HIV/AIDS patients. The isolates included 4 species of Microsporum, 7 species of Trichophyton, 1 (one) species of Epidermophyton and one species of Cladosporium. A total of 10 species of fungi were isolated from the HIV/AIDS patients. It was observed that some of the test individuals abused some antibiotic drugs. Some of the infected individuals were found to share their residential homes with domestic animals. It appeared the dog breeders contracted their fungal infections from either the infected pregnant dogs or the infected male dogs. The fungal isolates from HIV/AIDS patients appeared to be opportunistic organisms that stemmed from immune suppressions. It is known that susceptibility to superficial fungus infection varies but the nature of this immunity still appears to be obscure. The details of the results obtained from study have been discussed.

Abstract: Du to worldwide phenomenon of microbial resistance to commonly used therapeutic agents, antibiotics and antifungals as well, a non-traditional series of perspective ultra-short acting ?-adrenoceptor blockers, labeled as 1-4, has been in vitro evaluated against selected Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacterial strains as well as against yeast (C.albicans) by the minimum inhibitory concentration(MIC) assay. From chemical viewpoint, the presence of polar carboxy group within the structure of tested compounds has not found to be favourable structural feature because of its supposed splitting by the enzymes which have been produced by all concerned microorganisms. On the other hand, within inspected set of the compounds, the increase in the lipophilicity has meant moderate improvement of the effectiveness against S. aureus and C. albicans, reaching the maximum for the most lipophilic substance 4 which has shown MIC=0.78 mg.mL-1 for given bacteria and yeast as well.

Abstract: The Government of India has recently announced its intention to develop 25,000 MW of solar power through 25 Nos. solar parks i.e., @ 1,000 MW in each park, across the country and announced incentives to the states willing to develop the parks. The government aimed to utilize the large tracts of unusable land available in the country while promoting clean energy and giving big boost to the solar industry in the Country. The Gov. intends to extend grant of Rs 20 Lakh/MW from National Clean Energy Fund to meet the part of expenses required for development of infrastructure required for solar park.
