[Mycoplasma bovis-free breeding of cattle].

On a cattle farm latently infected by M. bovis, field studies aiming at the formation of a mycoplasma free herd, were carried out with a group of newborn female calves. These calves were strictly separated from their dams and any other cattle immediately after parturition. Intensive investigations for mycoplasmas were made over 30 months (mycoplasma isolation from nasal swabs, antibody detection by means of indirect hemagglutination test and ELISA technique). M. bovis could never be isolated from the samples. Also, there were no antibodies to M. bovis. In some animals antibody titers to M. bovis occurred after having contact with cattle infected with M. bovis. The results demonstrate a practicable way to establish cattle herds free from M. bovis infection.

[Neonatal alloimmune thrombocytopenia--can cryopreserved thrombocytes help? (Case report)].

We present a case report of the transfusion of cryopreserved HPA 1-negative platelets to a newborn suffering from neonatal alloimmune thrombocytopenia (NAT). A boy weighing 3450 g, born of a HPA1-negative mother with a platelet count of 9 Gpt/l after delivery, received two transfusions of cryopreserved HPA1-negative platelet concentrates. The first transfusion resulted in a platelet increment to 32 Gpt/l (CCI 11). A second transfusion was needed after a further drop of the platelet count on day 4 to 18 Gpt/l, resulting in an increment to 64 Gpt/l (CCI 36). Normal development during the first six months was obtained. In our opinion, cryopreserved HPA1-negative platelets could be helpful in the therapeutical strategy of NAT.

Structure of the levan elaborated by Streptococcus salivarius strain 51: an application of chemical-ionisation mass-spectrometry.

The polysaccharide elaborated by Streptococcus salivarius strain 51 contains beta-D-fructofuranose residues linked through positions 2 and 6, as well as 1, 2, and 6. The approximate numbers of terminal, non-reducing D-fructofuranose residues and those linked through positions 2 and 6, and through 1, 2, and 6 in the average repeating-unit are 1, 7, and 1, respectively. The branches through the beta-(2 leads to 1)-linkage contain up to at least four D-fructofuranose residues. Chemical-ionisation mass-spectrometry aids the assignment of structures to O-acetyl-O-methylalditols obtained in methylation analysis.
