Features of the occurrence of bacteria of Caulobacter genus in Lake Baikal in various econiches and in different seasons are investigated. The number of microorganisms was observed to vary from the absence in the majority of samples from the lake pelagialy to 700 000 p./ml in the mouth of the Barguzin river. For the first time, identification of Caulobacter from Lake Baikal was carried out by means of hybridization with the fluorescent oligonucleotide probe. Different morphological species of the bacteria of Caulobacter genus were determined with the help of investigations using the light, epifluorescent, transmission and scanning electron microscopes.
