Sero-prevalence of camel brucellosis (Camelus dromedarius) and phenotypic characteristics of Brucella melitensis biovar 3 in Shalateen City, Red Sea Governorate, Egypt
The objective of this study was to estimate the sero-prevalence of brucellosis in camels in Shalateen city, Red sea Governorate. A total of 801 Sera were collected from apparently healthy dromedary camels from 2014 to 2015 spring. Sera were consequently serologically tested and confirmed using Rose Bengal plate test (RBPT), buffer acidified plate antigen test (BAPAT) and complement fixation test (CFT). 103 (12.90%), 93...

Effect of crude toxins of Ustilaginoidea virens on rice seed germination
The plant pathogen Ustilaginoidea virens is known to generate secondary metabolite ustiloxins, which are poisonous to humans and domestic animals and to affect plant cells during the growth process. In this study, rice false smut was collected from different locations in Sichuan province and the strains isolated. The crude toxins of U. virens were extracted from the liquid culture medium of isolated strains to determine...

Lipolytic activity of fungi isolated from Jatropha curcas L. (physic nut) fruit rot
Isolation, identification and screening of lipid-degrading fungal organisms causing rot of unripe, ripe and dry fruits of Jatropha curcas L. were carried out, and determination of the fungus showing highest lipolytic activity on the substrate analysed from three different locations within Edo State, Nigeria was done using standard methods. Five fungal isolates (Curvularia geniculata, Lasiodiplodia theobromae,...

Variables associated to anti-HIV, anti-rubella antibodies, syphilis reagins and enteroparasitosis in pregnant women
The aim of this paper is to determine the prevalence of anti-HIV, anti-rubella antibodies, syphilis reagins and enteroparasitosis in pregnant women during their pre-natal monitoring at the Basic Health Units in the city of Umuarama (PR) and checking possible social-economic and behavioral associations. A cross-section study was performed in 690 pregnant women who went to have pre-natal checkup in the period from June...

Shelf life extension study of ogi and fufu using bacteriocin isolated from Lactobacillus acidophilus of fermented dairy products
Bacteriocins are antimicrobial peptides produced majorly by lactic acid bacteria (LAB), which act against food spoilage and pathogenic bacteria, thereby, extending the shelf life of food products. Bacteriocin produced by Lactobacillus acidophilus (isolated from yoghurt and nono) was extracted and incorporated in samples of ogi and fufu to evaluate its bio-preservative potential. Microbiological analysis was done at the...

Interaction between bacterial biocontrol-agents and strains of Xanthomonas axonopodis pv. phaseoli effects on biocontrol efficacy of common blight in beans
The bacterial biocontrol agents (BCAs) treatments were used for seed microbiolization; the bacterial biocontrol agents (BCAs) used selected from previous study on the control of Xanthomonas-axonopodis pv. phaseoli Xap) includes: Bacillus (DFs093, DFs348 and DFs769), Pseudomonas (DFs513, DFs831 and DFs842), Rhodococcus (DFs843 and DFs912), and the combinations C01 (DFs093+DFs769+DFs831), C02 (DFs093+DFs769+DFs842) and...

Isolation and characterization of extremely halotolerant Bacillus species from Dead Sea black mud and determination of their antimicrobial and hydrolytic activities
This is the first study that investigated the isolation of extremely halotolerant Bacillus species from Dead Sea black mud. Nine isolates obtained from black mud were considered to be extremely halotolerant Bacillus based on morphological, physiological, and biochemical properties. Most of their colonies were white to light yellow and circular to irregular. All isolates were Gram-positive rod-shaped endospore-forming...
