background and objectives: staphylococcal food poisoning is a gastrointestinal disease, which is caused by consumption of contaminated food with enterotoxins produced by staphylococcus aureus (ses). milk and its products are known sources of food borne diseases. this study was carried out to evaluate the prevalence of enterotoxigenic s. aureus strains in organic milk and cheese in tabriz - iran...

Aflatoxins are toxins which are usually produced by a kind of Aspergillus fungus named Flavus, Parasiticus, and Numius. There are 18 kinds of Aflatoxins have been discovered by scientists and Aflatoxin B1 is the most toxic and carcinogenic. Taking aflatoxins present in food causes lots of diseases like liver diseases, alcoholic liver, mutagenesis, and malformation in animals. It also has some o...

Several lines of evidence are presented for the involvement of spermidine in milk protein synthesis during hormone-dependent differentiation of mouse mammary epithelium in vitro. (a) When mammary explants from midpregnant mice are cultured in the presence of insulin, hydrocortisone, and prolactin, synthesis of casein and cr-lactalbumin increases markedly during the initial 48 hours. The require...

The objective of the present study was to evaluate the occurrence of Staphylococcus aureus in milk produced in 37 farms located in the regions of Ribeirão Preto and São Carlos, state of São Paulo, Brazil. Two-hundred and eight samples of milk from individual cows showing subclinical mastitis, and 37 samples of bulk tank milk were analyzed. S. aureus strains were detected in 18 (7.3%) milk sampl...

Frequency or completeness of milk removal from the lactating mammary gland regulates the rate of milk secretion by a mechanism which is local, chemical and inhibitory in nature. Screening of goat's milk proteins in rabbit mammary explant cultures identified a single whey protein of M(r) 7600 able to inhibit synthesis of milk constituents. The active whey protein, which we term FIL (Feedback inh...

The use of transgenic livestock is providing new methods for obtaining pharmaceutically useful proteins. However, the protein expression profiles of the transgenic animals, including expression of milk fat globule membrane (MFGM) proteins, have not been well characterized. In this study, we compared the MFGM protein expression profile of the colostrum and mature milk from three lines of transge...
