[An immunoglobulin-penicillinase conjugate for detecting the antigen of the causative agent of tularemia].

Immunoglobulin penicillinase conjugate for the detection of Fr. tularensis antigen in enzyme immunoassay has been prepared. Its sensitivity is 0.

[Focal nature of tularemia along the course of the Irtysh-Karaganda Canal].

The results of the epizootological survey of the track of the Irtysh-Karaganda canal for tularemia for the period of 1971-1982 are presented. Out of 928 fecal samples from mouse-hunting birds, 16 contained the specific antigen. From Arctic shrews a strain of Francisella tularensis was isolated.

[Geographical race typing of the causative agent of tularemia using antibiotics].

Reaction of the strains of the tularemia causative agent to erythromycin (100 gamma/ml) or oleandomycin (400 gamma/ml) is one of the taxonomic tests. The study of 82 strains of the holarctic race and 63 strains of the Central Asiatic race according to this test showed that the strains of the holarctic race were divided with respect to these macrolides into sensitive (biotype I) and resistant (biotype II). The strains of the both races were isolated at the territory of the Kazakh SSR.

[Sensitivity to the differential dose of erythromycin and oleandomycin of various holarctic strains of tularemia microbe isolated in the Kazakh SSR].

The presence of strains of holarctic race of tuleremia microbe, both sensitive and resistant to the differential doses of erythromycine and oleandomycine was revealed at the territoryn of Kazakh SSR. The existence of such strains does not permit to differentiate them into geographical races by the sensitivity to erythromycine and oleandomycine.
