Detection of virulence genes and antibiogram of Shiga toxin-producing Escherichia coli O157:H7 from slaughtered cattle and abattoir effluent in Zaria, Nigeria

Shiga toxin-producing Escherichia coli (STEC) O157:H7 is a formidable human pathogen causing food-borne diseases worldwide. The present study investigates virulence genes and determines the antimicrobial characteristics of STEC O157:H7 isolates from faecal and effluent samples at Zaria abattoir in Zaria. PCR assays were used to detect the virulence genes of STEC O157:H7 isolates. The isolates that produced stx genes...

Systematic studies on tetra SL hybrid hen technology and rearing for chicken welfare

In Serbia, there are 4 to 6 genotypes of hens used for producing eggs for consumption, including hybrid Tetra SL. The proper rearing of commercial flocks is critical for timely laying, intensity of laying capacity, number of laid eggs, and period of hen usage. The aim of this paper is to analyze the results of rearing the offspring of hybrid Tetra SL, from one-day-old chickens to eighteen-week-olds, with a review of the...

Effects of seed coat pigmentation on germination characteristics and antioxidant properties of Argyrolobium uniflorum ((Decne.) Jaub. & Spach) in southern Tunisia

Seeds of Argyrolobium uniflorum (Fabaceae), a spontaneous plant in arid and semi-arid regions of Tunisia, showed a color variability in their seed coats (green, orange, yellow and brown). The influence of the color of seed coat on germination and phytochemical seed composition was evaluated. Germination tests were carried out and the results obtained show that the applied chemical treatment (sulfuric acid) improved...

Screening of tuberculosis in highly exposed children in the population of Cameroon central region

Although the treatment for tuberculosis (TB) is available nowadays, it remains a real concern, especially since cases in children are often detected late and underreported. Studies have shown that elevated serum levels of C-reactive protein (CRP) are associated with TB in adults. This study aims to assess the CRP levels among the pediatric cases at Jamot Hospital (Yaoundé) and Meguemessi community in Cameroon....

Genetic diversity of Fusarium isolates infecting potato (Solanum tuberosum) and tobacco (Nicotiana tabacum) crops in Zimbabwe

Potato (Solanum tuberosum) and tobacco (Nicotiana tabacum) are important crops that contribute significantly to Zimbabwe’s economic development. However, they are attacked by Fusarium species leading to reduced yields, quality and profitability for farmers. A study was conducted to investigate the diversity of Fusarium spp. causing wilt and rots in both crops in Zimbabwe. Plants displaying symptoms of wilting,...
