    Production of avermectin A2a and monoglycosides A2a and B2a by a strain ofStreptomyces avermitilis

    A strain ofStreptomyces avermitilis producing almost predominantly avermectin A2a and monoglycosides A2a and B2a was described. Methods of analytical and preparative high performance liquid chromatography were us...

    Neutralization of bacterial viruses by antibodies of young animals

    The development of the avidity of 19S and 7S neutralizing antibodies was studied after the immunization of young rabbits with ΦX 174 bacteriophage. Both 19S and 7S antibodies formed during the entire course of...

    The influence of bursectomy and thymectomy on the primary antibody formation to various antigens

    Neonatal bursectomy and irradiation led to a negative antibody response to bovine serum albumin andSalmonella paratyphi A. In the case of immunization with ΦX 174 phage and sheep erythrocytes a substantial depres...

    Antibody response of young animals to bacteriophages of different immunological behaviour: Φ X 174 and T2

    The antibody response of piglets to the two immunologically unrelated phages Φ X 174 and T2 was studied. Antibodies against both antigens were observed already on the third day after immunization. Some differe...
