milk is often described as a complete food because it contains protein, sugar, fat, vitamins, and minerals. this study was performed to investigate risk factors affecting chemical and bacteriological quality of bulk tank milk. according to the following conducted experiments, the milk was divided into two standard and non-standard groups. then, effect of risk factors on making the samples non-s...
background:mastitis is the most economically importantdisease in dairy industry worldwide. bulk tank milk (btm)analysis has been suggested for monitoring the udder healthstatus at herd level. objectives: a cross-sectional study wasconducted to evaluate udder health status in 15 holstein dairyfarms located in qom province. methods: bulk tank somaticcell count (btmscc) was analyzed using opto-flu...
the purpose of this preliminary study was to determine the prevalence of raw milk contamination with listeria monocytogenes. in this study, 100 bulk tank milk samples were collected randomly and delivered to pegah pasteurization factory in mashhad.for isolation and identification of l. monocytogenes, the samples were first enriched using cold enrichment method in listeriaenrichment broth, follo...
the potential of bulk starter fermentation strategy for production of a cost-effective and safe source of β-galactosidase was investigated. three different bulk starter media with different compositions were selected, and an industrial yogurt starter culture strain, l. bulgaricus dsm 20081 was cultivated in these media under ph-controlled conditions (ph=5.6) at 43°c. the media consisted of 1) b...
Background and Objectives: According to the available evidence, consumption of milk and other dairy products among Iranians is far less than recommendations. The share of different milks (i.e., traditionally vs. industrially processed) and its associated variables are, however, neither consistent nor fully known in different Provinces.Materials and Methods: This cross-sectional study was conduc...
background: q fever is a zoonosis disease caused by an obligate intracellular organism coxiella burnetii. raw milk or dairy products that are produced by unpasteurized milk may contain virulent coxiella burnetii. the objective of this study was to determine the prevalence rate of c. burnetii in bulk milk samples from dairy sheep herds in fars, ghom, kerman, khuzestan and yazd provinces, iran. m...
this study was conducted to detect the common bacteria implicated in bovine mastitis in bulk tank milk by polymerase chain reaction (pcr). forty-four milk samples from bulk tank milk were obtained and submitted to our laboratory. to detect staphylococcus aureus, streptococcus agalactiae, streptococcus dysgalactiae, escherichia coli, streptococcus uberis, and streptococcus parauberis, two sets o...
Background: Q fever is a widespread zoonotic disease that is caused by obligate intracellular bacteria, Coxiella burnetii. Raw milk or dairy products that are produced from unpasteurized milk may contain virulent Coxiella burnetii. The objective of this study was to determine the prevalence rate of C. burnetii in raw and unpasteurized cow bulk tank milk samples of traditional domestic dairy pro...

Bovine viral diarrhoea virus (BVDV) is an important pathogen of dairy cattle. In this study, bulk milk samples representing a total of 4105 milking cows, from 18 dairy cattle herds in the suburb of Mashhad- Iran, were tested for presence of BVDV by the use of a nested reverse transcription polymerase chain reaction (Nested RT- PCR) assay. Non of the cows in the herds had been vaccinated against...
