The cows were randomly divided into four groups: control group A (92 cows), group B treated with placebo (base ointment of Benestermycin (Leo) without antibiotics) (105 cows), one intramammary dose per infected quarter, group C treated with Benestermycin (Leo), one intramammary dose being infused in each infected quarter (196 cows); and group D treated with Leocillin with dihydrostreptomycin (Leo); one intramammary dose being used every second day, on four occasions per infected quarter (215 cows). The study included infected cows. If less than three of the quarters of the udder were diagnosed as having mastitis at first sampling, only infected quarters were treated. Otherwise, all quarters were treated. Multivariable analysis showed no significant effect of therapy on culling rate. The control groups (A + B) had a greater increase of cows having at least one case of clinical mastitis compared to the therapy groups (C + D), (from 0.26 to 0.57 in controls comparing to 0.38 to 0.43 in therapy groups). The difference between control and therapy groups during lactation was close to significant both before and after in the lactation after therapy (P < 0.10). The multivariable analysis showed a significant benefit of dry-cow therapy of 0.409 In unit in geometric mean CMSCC (corresponding to 125,000/ml), 200,000/ml in weighted CMSCC and 189 kg milk yield per lactation. According to these results selective dry-cow therapy for cows included in this study is recommended.","PeriodicalId":23829,"journal":{"name":"Zentralblatt fur Veterinarmedizin. Reihe B.

Most of the group G streptococci grew in fluid media as granular sediment with clear supernatant and formed compact colonies in soft agar. The majority of the group G streptococci from dogs and bovines displayed CAMP-like synergistic haemolytic activities on sheep blood agar, fermented lactose and salicin and produced the enzyme alpha-D-galactosidase. The group G streptococci from humans mainly fermented trehalose and produced the enzyme beta-D-glucuronidase. In addition, some of the group G streptococci reacted with type antigen X and R and two cultures with M6 specific antiserum. A positive opacity factor reaction could be observed with few group G streptococci isolated from dogs and bovines, but not with those from humans. In binding studies with 125I-labelled plasma proteins most of the cultures interacted with 125I-immunoglobulin G and 125I-albumin. Binding of 125I-IgG was more pronounced among group G streptococci isolated from humans. The determination of antibiotic susceptibility revealed that most of the group G streptococci were susceptible to bacitracin, cefoxitin, clindamycin, erythromycin, gentamicin, penicillin and sulfamethoxazole-trimethoprim. Some of the cultures were resistant to minocycline, neomycin and tetracycline. All this data clearly distinguished group G streptococci isolated from animals and humans and could additionally be used for individual characterization of this microorganism. This might be useful in epidemiological aspects and contribute to understanding infections caused by these bacteria.","PeriodicalId":23829,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

Sera from 23 dairy herds (n = 205) from an island with no occurrence of salmonellosis, four herds (n = 303) with recent outbreaks of S. dublin and four herds (n = 168) with recent outbreaks of S. typhimurium, were tested in a SEF14-ELISA, S. dublin LPS (0:1, 9, 12) ELISA and S. typhimurium LPS (0:1, 4, 5, 12) ELISA. At a cut-off OD of 0.5, only one of the animals tested from the salmonellosis-free island showed significant seroreaction against the SEF14 antigen, which was confirmed in a Western-blot analysis. Three out of the four S. dublin-infected herds had several seroreactors in the SEF14-ELISA, whereas all the four herds were positive in the 0:1, 9, 12-ELISA. All but two samples (both from the same herd) in the four S. typhimurium-infected herds, positive in the 0:1, 4, 5, 12-ELISA, had OD values below 0.5 in the SEF14-ELISA. The results indicate that cattle can produce detectable specific antibodies against fimbrial antigens which may be used for screening of S. dublin-infected herds, particularly in areas with low prevalence of salmonellosis, increasing the predictive value of serology.","PeriodicalId":23829,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

All birds were maintained as a mixed population throughout the experiment of 45 days. The class specific antibody levels were determined at regular intervals by enzyme-linked immunosorbent assays. All birds responded to the vaccination stimulus as shown by a significant increase of antibody levels in both serum and lacrimal fluid. When comparing the IgG response of the chicken lines tested, LL chicks showed higher serum IBV-IgG values at the time of maximal response at days 5 and 9 post-vaccination (pv). This bird group also showed a more homogeneous (lowest coefficient of variation of values) serum IgG response. On day 13 pv and until the last serum sampling day (day 41 pv) all three chicken types showed statistically identical serum IBV-IgG levels. The local IgA response detected in lacrimal fluids showed differences between the chicks at the time of maximal levels (days 5 to 14 pv), the response of LL chicks being the highest. LL chicks maintained higher specific IgA levels than MT and HL chicks almost throughout the experimental period.
