Literák I . , I . Rychl ík: Genome Changes in the Toxoplasma gondii Strains During Laboratory Passages in Mice. Acta Vet. Brno 1999, 68: 203–208. Three strains of Toxoplasma gondii isolated from rabbits (K6 and K9) and a cat (K24) in the Czech Republic in 1994-95 were maintained in a tissue cyst form in laboratory mice by injections of brain homogenate every 4 6 months. These strains were passa...

Eighteen isolates of Aspergillus bombycis from samples of dust, insect frass, and soil collected from eight silkworm rearing facilities in Japan, as well as single silkworm rearing facilities in Indonesia and Malaysia, were subjected to DNA fingerprinting. PstI digests of total genomic DNA from each isolate were probed using the pAF 28 repetitive sequence. Among 18 isolates analyzed, 7 distinct...
