  Journal of Dairy & Veterinary Sciences - Juniper Publishers Introduction Mastitis caused by Coagulase-negative Staphylococci (CNS) usually remains subclinical or mildly clinical [1], however it was reported that CNS mastitis could be aggravated to severe clinical cases [2], but most CNS mastitis cases are chronic [3] based on their intramammary persistence for lactation milk exceeding periods, even extended to the upcoming ones [4]. CNS mastitis is a hidden but serious threat to dairy herd including further horizontal transmission to lactating cows and vertical to suckling calves because of environmental origin of most CNS and hidden subclinical nature [5]. CNS mastitis hazards aren’t exclusive to the dairy herds, but also extended to public health due to possible horizontal transmission of resistance genes (Soares et al., 2012) to other human pathogens or direct transmission to humans because of shared zoonotic virulent CNS species between animal and humans [6]. Pathogenicit...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract In the present study we analyzed 55 Pura Raza Chilena horses, from them, 37 males and 18 females clinically healthy, ranging between 5 and 15 years of age, in training for the competition. The objective of this study was to describe the hoof region by means of a morphometric analysis of the angle of the hoof, length of heels and shafts of the frog, obtaining reference parameters that can be used in this particular breed. For the measurement of the angle of the hoof, we used a podogoniometer and for measurement of the length of heels and shafts of the frog a caliper was used. As outcome, it was observed that the angle of the hoof presented an average of 55.88° in the thoracic limbs and 55.46° in the pelvic limbs, without statistically significant differences. The females presented an angle of 54.15° and the males 56.40°, observing significant differences. The results indicate that the heels of the pelvic limb...

  Journal of Dairy & Veterinary Sciences - Juniper publishers Abstract This study was carried out to investigate the effect of microwave radiation on the viability of Brucella melitensis in contaminated cattle milk through establishing a correlation between milk volumes, microwave exposure time, measured Celsius temperature and viable counts of B. melitensis in inoculated milk. Microwave appliances were used in houses and many food stores in Egyptand worldwide, for warming milk that processed for human consumption. Microwave heating was performed using a household electronic microwave oven (Kenwood MW 579, a frequency of 2,450 MHz, and power of 900W). Brucella-free milk is inoculated with B. melitensis in a dose of (1.3 X 108 CFU / ml) and samples are divided into 100 ml and 200 ml volumes and maintained at room temperature (22 °C ± 3°C) or refrigeration temperature (5 ºC ± 2 ºC) prior to microwave exposure. Microwave radiations with full power (P = 100) eliminate B. melitensis...
