The capacity of wide-spectrum antibiotics kefzol and ristomycin to activate the persisting tick-borne encephalitis (TBE) virus and cause an exacerbation of chronic process was investigated in Syrian hamsters in whom a prolonged (77 to 270 days) persistent TBE infection was induced by three TBE strains: Vasilchenko, V-383, and 205. The degree of antibiotic-induced activation was assessed using the criteria characterizing the reproduction and peculiarities of persisting TBE virus, immunodepression, and morphologic changes in the central nervous system. Effects of kefzol and ristomycin were compared with those of 8 antibiotics studied previously. Ristomycin, levomycetin (chloramphycin), penicillin, ampicillin (ampital), and levoridan were referred to drugs devoid of evident provoking effect. Kefzol (cefamezin), florimycin (viomycin), and kanamycin (kanamytrex) were characterized as weak activators and streptomycin and tetracycline as potent activators of the persisting TBE virus. These data may be used when selecting alternative agents for therapy of secondary bacterial infections concomitant with TBE.
