In the animal feed industry, an ever growing increase in quality has been observed, but the main feature of a food is related to its security because the contamination poses a risk to animal health. The problems caused by fungal colonization is the significant loss of food quality, because even those who do not produce mycotoxins cause losses in the nutritional quality. Researches show that the most important Fumonisins... Read more.

Meat products are clearly associated with foodborne pathogens including, antibiotic-resistant strains. Population growth and growing consumer demand facilitate the transmission of foodborne pathogens, particularly in developing countries. To determine the prevalence of antibiotic-resistant Salmonella in goat meat, a study was done in Tanzania (June to July, 2015). Overall 120 goat meat samples were collected from... Read more.

One of the factors that make the treatment of Enterococcus faecalis infections difficult is their ability to form biofilm, as well as their natural and acquired resistance to antibiotics which does not have specific drugs for their inhibition. This fact makes essential the search for alternative treatments, as the use of probiotics strains of Lactobacillus rhamnosus has been effective in the treatment of some diseases.... Read more.

Inoculation of promiscuous soybean with rhizobia has been proven to improve yield. Screenhouse pot experiments were conducted to assess the response of promiscuous soybean, TGx1448-2E to rhizobia inoculation and to determine the relative efficiency of indigenous rhizobia from soils collected from the Northern and Southern Guinea and Sudan Savanna agro-ecological zones of Nigeria. Soils were collected at 0 to 20 cm depth... Read more.
