Samples of milk from 23 mothers attending the department of obstetrics and gynaecology and 36 who donated milk to the department's milk bank were cultured for cytomegalovirus. Virus was isolated from samples from 12 of the milk donors but none of the mothers attending the department; follow-up studies during lactation in seven of these 12 women showed that five continued to excrete the virus. S...

Introduction: Brucellosis is a zoonotic disease caused by the members of the genus Brucella. This bacterium is transmitted to humans through exposure to infected animals or via consumption of contaminated dairy products. Cultivation of the bacteria or amplification of its DNA using polymerase chain reaction (PCR) are conventional diagnostic approaches for definitive identification of Brucella i...

Experiments were conducted to test whether enhancement of antioxidant status could improve fertility and milk yield in dairy cows and resistance of cultured embryos to heat shock. Three experiments in three herds were performed to evaluate the effect of multiple intramuscular injections of 500 mg of vitamin E and 50 mg of selenium at 8 to 21 d before expected calving and at 30 and 80 d postpart...

Mathematical models were developed and evaluated for growth of psychrotolerant pseudomonads in chilled milk and in cottage cheese with cultured cream dressing. The mathematical models include the effect of temperature, pH, NaCl, lactic acid and sorbic acid. A simplified cardinal parameter growth rate model was developed based on growth in broth. Subsequently, the reference growth rate parameter...

A rare outbreak of anaerobic nitrite burn in fermented sausage afforded the isolation and characterization of the offending microorgansim which was identified as a Staphylococcus sp. Unlike most staphylococci, this organism reduces nitrite as well as nitrate.

Objective: inconclusive evidence exists regarding potential cariogenicity of milk formulas compared to breast milk.The study aimed compare Salivary Streptococcus mutans (S. mutans) and lactobacilli detection counts amongbreastfed (B), plain formula (France Lait 1) (FL) probiotic supplemented (Nan 1 optipro) (N) infantsand assess in-vitro growth these bacteria in samples. Material Methods:saliva...

ABSTRACT: The growth rate of two probiotic strains with documented health effects was studied in ultra-high temperature treated milk separately and beside each other. The probiotic strains were Lactobacillus acidophilus (La-5) and Bifidobacterium lactis (Bb-12). Fermentation was followed for 12 h at 37 ˚C and the samples were analyzed for pH, titratable acidity and viable counts of probiotic ba...

Objectives: An in vitro study to assess the effect of different milk products on hardness enamel surfaces. Materials and Methods: Extracted primary permanent teeth incisors (15 deciduous 15 permanent) were collected cleaned. The extracted then divided randomly into five groups (n=6 per group): G1- distilled water (control); G2- fresh (cow milk); G3- chocolate flavoured milk; G4- orange cultured...

One of the important routes Mycobacterium avium subsp. paratuberculosis (MAP) transmission in dairy calves is milk. The aim present study was to assess efficacy milk treatments prevent MAP infection calves. A one-year longitudinal carried out. Newborn were assigned one four experimental groups: 5 received naturally MAP-contaminated milk, copper treated 4 fed calf replacer, and 3 UHT pasteurized...

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....
