..5 kg per day higher than the non-vaccinated control cows. These results suggest that the new vaccine elicits a non-specific health improvement of the udder in addition to specific protection against S. aureus...

..The Yc was significantly lower in the infected halves, and clotting time was significantly longer. The mechanisms of the effects of SM on milk yield and Yc in goats and sheep are discussed and compared...

..Moreover, all quarters challenged in the vaccinated cows, regardless of whether they were successfully infected or not with S. aureus, exhibited very mild inflammatory reactions, identified by their low SCCs (<100,000)...

..4 times as high in the infected glands than in the uninfected ones. Curd yield was significantly lower in the infected glands than in the uninfected ones...

..aureus strains. The results obtained showed that this vaccine exhibits a broad spectrum of antigenic and immunogenic properties that protects mice from homologues and hetrologous S. aureus challenge...

..An association was found between the combinations of expressed bands and the cow responses: the majority of the cases could be linked to the expression of bands B and C...

..Immunization with a vaccine prepared from either of the subgroups protected mice only from the homologues but not from the heterologues, whereas the bivalent vaccine protected mice from both subgroups...

..Our findings demonstrate that pre-exposure of mice to a low dose of certain S. aureus strains could provide protection and that the antibodies produced could have an important protective role...

..Mo numbers were high in most of those infected quarters, and were localized around the connective tissue and within the AL...

....

..This finding could be attributed to lateral virus transmission from seropositive to seronegative kids because of lack of segregation within the flock...

..It is suggested that application of a wider range of measures that reflect the immune status would enable the identification of most cows prone to new IMI...

..coli population; they seem better able to multiply in the udder medium and to evade the host cellular innate immune response, and are genetically distinct from most environmental strains...

..58. Persistency in the Israeli Holstein population was analyzed by the multitrait animal model. The genetic trend since 1985 for the multiparity index was 0.22% persistency/yr, even though there was no direct selection on persistency...

..The ability of the AfiLab to perform this task was validated online and statistically by calibration against laboratory testing procedures...

..A few but not all of the exosecretions that activated the CD25 receptor on T-cells also activated the ACT3 receptor on CD4+ cells...

..Taken together, our in vitro and in vivo results show that apramycin is effective against E. coli by preventing colonization of the gut by the bacteria, which could lead to a reduction of colibacillosis in poultry...

..Thus, development of an improved quality control methodology may be important for the production of high-quality milk...

..The results suggest that LukM/ LukF' induce inflammation into the udder by a mechanism similar to that of LPS or by a unique mechanism(s) which requires further investigation...

..The specific response of XO to bacteria species and the resulting bacteria-dependent nitrosative stress further demonstrates that it is part of the gland immune system...

..A preventive treatment during the dry period should, therefore, be considered as an effective means of reducing the current rate of bacterial infections in goats...

..Milk composition (fat, protein and lactose) varied among flocks, with lower mean total protein in uninfected halves than in infected ones and higher lactose in uninfected than infected halves...

..Recommendations for minimizing the deterioration in milk quality during commercial storage are presented...

..The outbreak caused by an atypical CNS underlines the need for accurate biochemical and genetic methods for ultimate identification of CNS to the species level...

..The present study revealed that a large variety of Ps. aeruginosa strains may cause mastitis outbreaks in sheep, goat and cattle in Israel...

..The innate immune system play a major role in preventing intramammary infection during milk stasis and its activation may increase its effectiveness...

..Thus, we suggest its adoption by microbiology diagnostic laboratories for the provision of accurate antimicrobial susceptibility results when using the disk diffusion test...

..Ruthless culling of all infected and carrier animals was an essential part of the control program against Pseudomonas aeruginosa mastitis...

..We propose MDV has evolved to increase specific gene transcription and genome copies per cell to compensate for ICS. We speculate that the bi-directional shared pp38/origin of replication promoter, is central to this mechanism...
