Human papilloma virus and cervical neoplasia in HIV positive women: A non systematic review
Human papilloma-virus (HPV) infection confers 85-90% of the attributable risk for the development of cervical dysplasia. Worldwide and in particular in Nigeria, HPV 16 has been shown as the most prevalent HPV type and it also contributes more to the development of invasive squamous cell carcinoma. Studies have also shown that the prevalence of HPV is higher among HIV-positive women than among HIV-negative women of all...

Chemical control of dry bubble disease induced by Verticillium fungicola [Preuss] Hassebr on white button mushroom, Agaricus bisporous
Dry bubble disease induced by Verticillium fungicola has been observed as an important disease of white button mushroom (Agaricus bisporus) in India. The symptoms produced on well differentiated fruit body are localized light brown depressed spots. The adjacent spots coalesce together to form irregular blotches. If the host pathogen infection is established before differentiation, sclerodermoid fruiting bodies appear on...

Screening for exopolysaccharide-producing strains of thermophilic lactic acid bacteria isolated from Algerian raw camel milk
Exopolysaccharides synthesized by lactic acid bacteria play a major role in the manufacturing of fermented dairy products as thickening agents. Exploration of the biodiversity of wild lactic acid bacteria from natural environments is currently the most suitable approach to search for the desired exopolysaccharide-phenotype. A total of 82 thermophilic lactic acid bacteria strains were isolated from Algerian raw camel...

Properties of Enterococcus faecalis, a new probiotic bacterium isolated from the intestine of snakehead fish (Channa striatus Bloch)
The present study aimed to isolate and characterize the lactic acid bacteria (LAB) from the intestine of snakehead (Channa striatus) fingerling to be used as a new probiotic in aquaculture. The total colony count of bacteria in the fish intestine was 2.1 × 106 cfu/g. Five LAB were isolated from the intestine of twenty fish and one of these isolates, LAB-4 was identified as Enterococcus faecalis by conventional and...

Bacteriological assessment of the quality of Brassica oleracea var. capitata grown in the Accra Metropolis, Ghana
Bacterial and other microbial contamination of fresh vegetables from the farm or garden to the market and to the final consumer remain a problem worldwide. This study was designed to evaluate the various possible bacterial species responsible for the contamination of Brassica oleracea var. capitata (cabbage) in the Korle-Bu vegetable garden and Agbogbloshie market in the Accra Metropolis, Ghana. Sixty (60) cabbage...

Application of bacterial biomass as a potential heavy metal bio-removal agent
Water has been the most important element for saving life; the major global health problem has been water pollution that may be due to the wastewater discharge into the water bodies. Several techniques have been used for water treatment that is, physical, chemical and biological methods. Recently, the third method was the most effective one for the wastewater treatment. In this work twenty bacterial isolates were...

Detection of outbreak caused by multi-drug resistant Acinetobacter baumannii in Assiut University Hospitals
There is mounting evidence that Acinetobacter baumannii has a naturally occurring carbapenemase gene intrinsic in this species. Presence of class 1 integrase gene in Acinetobacter isolates is a useful marker for causing outbreaks in hospitals and for being epidemic strains of A. baumannii. The goal of the present study was to detect the resistance and outbreak marker genes by multiplex polymerase chain reaction (PCR)...

Rapid detection of virulence associated genes in Streptococcal isolates from bovine mastitis
In the present study, 15 S. agalactiae out of 56 streptococcal isolates recovered from 98 milk samples collected from clinical cases, one organized farm and two unorganized sectors in and around Bangalore. All the streptococcal isolates were confirmed at genus level using genus specific primers targeting tuf gene of Streptococcus. Species level identification for S. agalactiae, S. dysgalactiae and S. uberis was done...

Effect of carbon and nitrogen sources on exopolysacharide production by rhizobial isolates from root nodules of Vigna trilobata
Twenty five (25) rhizobial strains were isolated from root nodules of Vigna trilobata cultivars grew in soils collected from all districts of Andhra Pradesh, India. Five out of 25 rhizobial strains which produced copious amount of Exopolysaccharides (EPS) on Yeast Extract Mannitol Agar (YMA) medium with congo red were identified by sequencing of their 16S rDNAs. The amount of EPS produced by these five strains...
