AIM The virulence-associated protein-A of Staphylococcus aureus, encoded by spa gene shows a variation in length in different strains. In this study, the spa gene variation in S. aureus strains was studied which were isolated from subclinical cases of bovine mastitis. MATERIALS AND METHODS About 38 isolatesof S. aureus were recovered from Holstein-Friesian (HF) crossbred (n=16) and Rathi catt...

Subclinical mastitis is an important udder disease that negatively affects both the animal health and reduces profitability in dairy farms. The increasing performance of thermal cameras over time their usability different areas increase use livestocks. Infrared thermography (IRT) technology a noninvasive method can estimate surface temperature objects. objective this study was to evaluate early...

Subclinical mastitis is one of the most significant diseases that cause economic losses in dairy cattle farming. This investigation was conducted on 112 head Holstein Friesian cows order to reveal relationship between subclinical and electrical conductivity milk composition quality. In study, CMT (California Mastitis Test) CSCC (Classified Somatic Cell Count) used diagnosis were as a binary res...

A variety of diagnostic tests are routinely used to evaluate milk quality on dairy farms. Tests such as bulk milk bacterial counts, bulk tank somatic cell count and tests for adulterants such as water, sediment or antibiotics are routinely used by regulatory agencies. Other tests such as individual cow somatic cell count values, Staphylococcus aureus milk antibody tests, the California Mastitis...

The main aim was to assess the impact of mastitis on technical and economic results of a dairy herd under current Swedish farming conditions. The second aim was to investigate the effects obtained by withdrawing milk with high somatic cell count (SCC). A dynamic and stochastic simulation model, SimHerd, was used to study the effects of mastitis in a herd with 150 cows. Results given the initial...

Infections with Chlamydophila abortus and C. pecorum are highly prevalent in cattle and have been associated with bovine mastitis. A prospective cohort study was conducted with a herd of 140 Holstein dairy cows to investigate the influence of Chlamydophila infection on subclinical inflammation of the bovine mammary gland as characterized by somatic cell numbers in milk. PCR detection of C. abor...

A total of 108 heifers were included in a placebo-controlled multicenter study on the use of an experimental Staphylococcus aureus mastitis vaccine containing whole, inactivated bacteria with pseudocapsule, alpha and beta toxoids, and a mineral oil as adjuvant. The heifers were injected in the area of the supramammary lymph nodes twice before calving and were observed and sampled throughout the...

Subclinical mastitis is a common and easily disseminated disease in dairy herds. Its routine diagnosis via bacterial culture and biochemical identification is a difficult and time-consuming process. In this work, we show that matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) allows bacterial identification with high confidence and speed (1 d for bacteri...

Subclinical mastitis is one of the main problems in development dairy farming Indonesia. Several screening test tools have been developed to support control program for this problem. This study aimed assess suitability Draminski detector as a tool subclinical cows. Quaternary milk samples from 27 cows during normal lactation Pondok Ranggon area, East Jakarta were collected be evaluated possibil...

INTRODUCTION Risk factors for breast milk transmission of HIV-1 from mother to child include high plasma and breast milk viral load, low maternal CD4 count and breast pathology such as mastitis. OBJECTIVE To determine the impact of nevirapine and subclinical mastitis on HIV-1 RNA in maternal plasma and breast milk after intrapartum single-dose nevirapine combined with either 1-week tail of Co...
