Avian ochratoxicosis: A review
Ochratoxicosis is one of the most common mycotoxicoses in poultry, specially commercial poultry. It is caused by most dangerous mycotoxin because it causes oncogenic effects in embryos, that is, ochratoxin A. The presence of ochratoxin-A in poultry feed contributes significantly to health disorders and decreases production. This is one of the causes of economic losses in poultry industry due to increased mortality,...

Dental plaque of children as probable Helicobacter pylori reservoir
Helicobacter pylori is a spiral gram negative bacterium that normally grows in the stomach, and is the main causal agent of gastritis and peptic ulcers. In 1994, The International Agency for Research on Cancer recognized H. pylori as a carcinogenic factor for stomach cancer. The oral cavity has been proposed as a reservoir for H. pylori and several authors have demonstrated the presence in adult patients of the organism...

Evaluation of fungicide application on late blight in popular potato cultivars of the north eastern Himalayan hills of India
Potato late blight is one of the major constraints to potato cultivation in the north eastern hill region of India. Eight popular potato cultivars (Kufri Girdhari, Kufri Megha, Kufri Himsona, Kufri Himalini, Kufri Giriraj, Kufri Jyoti, Kufri Kanchan and Kufri Shailja) were evaluated for late blight disease progress and yield potential with or without the application of fungicide in the field. Blight appeared 103 days...

Microbiological and parasitic quality of suya (roasted beef) sold in Makurdi, Benue State, Nigeria
This work is an investigation of the contaminants (microbial and parasitic) of suya (n=240) sold within Makurdi metropolis. The followings were detected in the roasted beef: bacteria: Escherichia. coli, Staphylococcus aureus, Salmonella sp., Klebsiella sp., Shigella sp., Enterococcus sp., Streptococcus sp., Bacillus sp., and Pseudomonas sp.; fungi: Aspergillus sp., Penicillum sp., Rhizopus sp. and yeasts; protozoa:...

Occurrence and antimicrobial susceptibility of Escherichia coli and Salmonella spp. isolated from “zoom-koom†beverage and ice in Ouagadougou, Burkina Faso
Pathogenic bacteria contaminate beverages and make consumers to have diarrhoeal diseases. This study was carried out to assess the occurrence and antimicrobial susceptibility of Escherichia coli and Salmonella spp. isolated from “zoom-koom” beverages and ice from open markets of Ouagadougou. One hundred samples of both “zoom-koom” and ice were analyzed using standard microbiological methods....

Exploration of Serratia entomophila AB2 for lepidopteran pest control and productivity of groundnut
The bacterial isolate Serratia entomophila AB2 having multidimensional attributes like larvacidal activity and nutrient-solubilizing capability was used to test its effect on productivity of groundnut. Two different inorganic carriers (talcum powder and vermiculite) based formulations of the bacterial isolate were also tested along with the unformulated product and 100% recommended dose of NPK (60:60:50) for comparative...

Isolation and characterization of Chromobacterium violaceum from a disused tin-mining lake in Malaysia
During a survey of microorganisms from a disused tin-mining lake in Kampar, Perak, Malaysia, a distinct bacterium producing a purple pigment was isolated. The isolate was characterized by morphological observation, followed by a series of conventional biochemical tests, physiological tests, as well as antibacterial tests, and identified as Chromobactertium violaceum. It was a facultatively anaerobic, motile,...

Influence of bacterial species on adhesion to stainless steel
To assess the adherence of bacteria in stainless steel used in food processing, we developed an experimental model of a milk circulation line equipped with coupons T, 90° (elbow) and cylindrical-shaped constructed AISI 304 stainless steel. We evaluated the adherence of Enterococcus faecium, Pseudomonas aeruginosa ATCC 15442 and Bacillus cereus NCTC 11145 in vegetative and spore forms, before and after milk...

Antibiotic resistance trend of Staphylococcus aureus isolated between 2010 and 2012 from mastitis cases in Azawak zebu in Niger
The present study was conducted at the Sahelian Experimental Station in Toukounous Niger, on three herds of Azawak zebu breed in order to evaluate antimicrobial susceptibility of a total of 43 Staphylococcus aureus isolated from 164 milk samples of cows with subclinical mastitis from 2010 to 2012. The highest frequency of resistance was observed for the β-lactam family: penicillin (46%) followed by oxacillin (12%)....

Non-invasive detection of Helicobacter pylori virulence genotypes ureA, vacA, cagA and babA2 among asymptomatic Egyptian infants
Helicobacter pylori is a microaerophilic spiral-shaped Gram-negative bacterium that infects approximately 50% of the world’s population, particularly in developing countries. Infections early in childhood are postulated to induce a low-grade chronic inflammatory condition. This study aimed to determine the prevalence of H. pylori virulence genotypes ureA, vacA, cagA and babA2 among asymptomatic Egyptian infants...
