Background  Campylobacteriosis is a zoonotic disease, and animals such as poultry, pigs and cattle may act as reservoirs for  Campylobacter  spp. Cattle shed  Campylobacter  spp. into the environment and they can act as a reservoir for human infection directly via contact with cattle or their faeces or indirectly by consumption of contaminated food. The aim of this study was to determine the prevalence, the quantitative load and the genetic strain diversity of  Campylobacter  spp. in dairy cattle of different age groups.    Results  Faecal samples of 200 dairy cattle from three farms in the central part of Lithuania were collected and examined for  Campylobacter . Cattle herds of all three farms were  Campylobacter  spp. positive, with a prevalence ranging from 75% (farm I), 77.5% (farm II) to 83.3% (farm III). Overall, the highest prevalence was detected in calves (86.5%) and heifers (86.2%). In contrast, the lowest  Campylobacter  prevalence was detectable in dairy cows (60.6%).  C. jejuni ,  C. coli ,  C. lari  and  C. fetus  subsp.  fetus  were identified in faecal samples of dairy cattle.  C. upsaliensis  was not detectable in any sample. The high counts of  Campylobacter  spp. were observed in faecal material of dairy cattle (average 4.5 log 10  cfu/g). The highest numbers of  Campylobacter  spp. were found in faecal samples from calves (average 5.3 log 10  cfu/g), whereas, faecal samples from cows harboured the lowest number of  Campylobacter  spp. (average 3.7 log 10  cfu/g). Genotyping by  fla A PCR-RFLP analysis of selected  C. jejuni  isolates showed that some genotypes were present in all farms and all age groups. However, farm or age specific genotypes were also identified.    Conclusions  Future studies are needed to investigate risk factors related to the degree of colonisation in cattle. Based on that, possible measures to reduce the colonisation and subsequent shedding of  Campylobacter  in cattle could be established. It is important to further investigate the epidemiology of  Campylobacter  in the cattle population in order to assess associated risks to public health.
