The objective of this study was to evaluate the occurrence of aflatoxin M1 (AFM1) in raw milk samples from 18 dairy farms in the Yangtze River Delta region during four different seasons. A total of 72 tank milk samples was collected with 18 samples for each season. Milk AFM1 was detected using LC-MS/MS. The AFM1 was detected in 43 milk samples (59.7%) ranging in concentration from 10 to 420 ng/...
A simple, rapid and sensitive immunogold chromatographic strip test based on a monoclonal antibody was developed for the detection of melamine (MEL) residues in raw milk, milk products and animal feed. The limit of detection was estimated to be 0.05 μg/mL in raw milk, since the detection test line on the strip test completely disappeared at this concentration. The limit of detection was 2 μg/mL...
BACKGROUND Consumption of raw milk and unpasteurized dairy products is common in Tunisia where bovine tuberculosis remains enzootic. We herein investigated the frequency of M. bovis isolation from raw milk. METHODS Three hundred and six milk samples collected from 102 infected cows in different Tunisian regions were analysed. M. bovis isolates were further characterized by spoligotyping and v...
This study investigated the influence of alpine grazing on vitamin D (vitD) and bone metabolism in sheep and goats. Two groups of five adult lactating East Friesian milk sheep and Saanen dairy goats were kept on pastures at 2,000 to 2,600 m a.s.l. (SA: sheep alpine; GA: goats alpine) and 400 m a.s.l. (SL: sheep lowland; GL: goats lowland). The animals were milked twice daily and the milk yield ...
Contagious agalactia (CA) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. Mycoplasma (M.) agalactiae is the main cause of the disease in sheep and goats. The aim of the present study was to detect M. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or witho...
the suitability of milk preserved by refrigeration and co2 addition for the manufacture of plain yoghurt using two commercial strains of lactobacillus delbrueckii ssp. bulgaricus and streptoccocus thermophilus and probiotic yoghurt by lactobacillus acidophilus was evaluated. yoghurts (plain and probiotic) manufactured after milk pasteurization, from fresh and refrigerated co2 treated samples (p...
Mastitis is an inflammatory reaction of the mammary tissue in response to the introduction and multiplication of pathogens and is characterized by increasing somatic cell count (SCC) in milk. The main objective of present study is to assess the probable associations between somatic cell (SC) levels and calcium and phosphorus and ratio of Ca/P in raw milk. Milk samples were collected from indivi...
This study investigated the influence of alpine grazing on vitamin D (vitD) and bone metabolism in sheep and goats. Two groups of five adult lactating East Friesian milk sheep and Saanen dairy goats were kept on pastures at 2,000 to 2,600 m a.s.l. (SA: sheep alpine; GA: goats alpine) and 400 m a.s.l. (SL: sheep lowland; GL: goats lowland). The animals were milked twice daily and the milk yield ...
Consumption of raw cow's milk instead of industrially processed milk has been reported to protect children from developing asthma, allergies, and respiratory infections. Several heat-sensitive milk serum proteins have been implied in this effect though unbiased assessment of milk proteins in general is missing. The aim of this study was to compare the native milk serum proteome between raw cow'...
A method based on amino-modified silica-coated magnetic nanoparticles (ASMNPs) and polymerase chain reaction (PCR) was developed to rapidly and sensitively detect foodborne pathogens in raw milk. After optimizing parameters such as pH, temperature, and time, a trace amount of genomic DNA of pathogens could be extracted directly from complex matrices such as raw milk using ASMNPs. The magnetical...
