Detection of Coxiella burnetii by Real-Time PCR in Raw Milk and Traditional Cheese Distributed in Tehran Province
Coxiella burnetii is common causative agent of Q fever in humans and animals. Although the main route of human infection is through inhalation of contaminated aerosols (dust), but oral transmission through contaminated raw milk and dairy products are also possible routes of infection. The aim of this study was to identify and determine the extent of contamination and prevalence of Coxiella burn...
متن کاملDetection of Coxeilla brunetii in bulk tank milk samples from dairy bovine farms using nested-PCR in Qom, Iran, 2011
BACKGROUND: Q fever is a zoonotic disease caused byCoxiella burnetii, a species of bacteria that is distributedworldwide. In cattle, Coxiella burnetii infections are generallyasymptomatic but can also be associated with reproductivedisorders. OBJECTIVES: The aim of this study was to achievemolecular detection of Coxiella burnetii in dairy bovine milkfarms using Nested PCR in Qom province, Iran....
متن کاملAssociation between Coxiella burnetii shedding in milk and subclinical mastitis in dairy cattle.
The objective of this research was to explore the potential association between Coxiella burnetii shedding in milk and chronic subclinical mastitis in dairy cattle. In two separate studies, we identified an association between PCR-based detection of C. burnetii in milk and chronic subclinical mastitis in lactating dairy cows. These studies were conducted in a commercial dairy herd where there w...
متن کاملPrevalence of Coxiella burnetii in Bulk Tank Milk Samples from Dairy Cattle in West and Northwest of Iran
ABSTRACT Background and Objectives: Q fever is a zoonotic disease caused by an obligate gram-negative intracellular pathogen called Coxiella burnetii. The aim of this study was to determine the seroprevalence of anti-C. burnetii antibodies in bulk tank milk (BTM) samples of dairy cattle in west and northwest of Iran. Me...
متن کاملDynamics of relationship between the presence of Coxiella burnetii DNA, antibodies, and intrinsic variables in cow milk and bulk tank milk from Danish dairy cattle.
Milk samples of 12 Danish dairy herds were collected 3 times during an 11-mo period and tested for Coxiella burnetii DNA by real-time PCR, detecting the IS1111 element, and for the presence of antibodies against the bacterium by ELISA. On average, 25% of 1,514 samples were seropositive and 32% were positive for C. burnetii DNA. Among the 485 DNA-positive samples, quantification cycle values ran...
