Bartonella spp. Infection in Edible Dormice and Their Fleas
Klimešová, Běla ; Votýpka, Jan (advisor) ; Balážová, Alena (referee)
Bartonellosis is a group of emerging infectious diseases caused by facultatively intraerythrocytic bacteria transmitted between vertebrate hosts by arthropod vectors. Although only some Bartonella spp. are traditionally associated with human diseases, it was proposed that virtually any species can have zoonotic potential. The highest diversity of species was described from rodents acting as reservoirs with variable prevalence reaching up to 90%. Fleas associated with mammalian hosts play an important role in the Bartonella sp. lifecycle and are described to act not only as competent vectors but also as reservoirs for several species. The role of edible dormice (Glis glis), which often interacts with humans, and their fleas in the bartonellae transmission and lifecycle has so far been unknown; therefore, the prevalence and diversity of Bartonella spp. in edible dormice in the Czech Republic were studied. Complementary PCR analysis of four loci (gltA, rpoB, ftsZ, ITS), MALDI- TOF, and cultivation was performed to identify Bartonella sp. infections. The prevalence reaching 90% was found in dormice and their fleas. Altogether, four species were found and several genotypes of B. grahamii-like and yet undescribed Bartonella sp. were cultivated, and their morphology and growth requirements were...

Bats of the genus Plecotus in the fossil record of central and SE Europe.
Balážová, Alena ; Horáček, Ivan (advisor) ; Hanák, Vladimír (referee)
In this thesis a review and detailed morphometric analysis of fossil material of genus Plecotus Geoffroy, 1818 (Microchiroptera) from central Europe from miocene till recent was done. Both metric and phenetic features of skull ant teeth were compared with recent european species of this genus. The most detailed attention was focused on fossil species Plecotus abeli Wettstein-Westersheim 1923, which is most likely only an extreme phenotypic variety of Plecotus auritus group. Fossil record from Karlukovo (Bulgaria) was studied too. The first record of Plecotus macrobullaris Kuzjakin, 1965 was found there.
