In this study, we propose a possible way of obtaining reproductive and respiratory syndrome virus (PRRSV) free offspring from genetically valuable lines of Přeštice black-pied boars com- ming from PRRSV-positive pig breeding herds with the use of artificial insemination (AI). The ejaculates were collected from 4 different lines of boars. Samples of fresh semen were not detected with the virus and 12 sows were inseminated. Blood samples of sows and their offspring were repeatedly tested for the virus but the results were negative. We managed in this way to maintain the endangered population of this breed and obtain PRRSV-free offspring.

Anaplasma platys, the aetiological agent of infectious canine cyclic thrombocytopaenia, infects platelets of dogs, usually causing mild or asymptomatic disease. Although A. platys is transmitted by ticks, as for other Anaplasma species, alternative modes of transmission may be involved. The aim of the present study was to evaluate the occurrence of A. platys infection in litters of puppies, which could suggest possible vertical transmission. Twelve litters, together with the respective bitches, were included in the study for the detection of A. platys DNA by PCR, followed by sequencing. Five puppies, from 2/4 litters <28 days of age, tested positive for A. platys DNA. No puppies from eight litters 1-3 months of age tested positive for A. platys DNA. The identical sequences (16S rRNA and gltA partial gene), the absence of ticks on puppies at the time of collection and the young age of the five infected puppies suggest vertical transmission of A. platys. This mode of transmission might contribute to the maintenance and spread of the pathogen in canine populations.

Transmission of canine leishmaniosis (CanL) is described in three consecutive generations of female Boxers living in a non-endemic environment in the Czech Republic. Infection of the first generation female likely occurred during a breeding visit to Italy and the dog died with typical clinical signs of the disease but without definitive laboratory diagnosis. The second and third generation offsprings never left the Czech Republic, suffered from clinical CanL confirmed by polymerase chain reaction and serology, and were apparently infected by transplacental transmission. Persistence of CanL in the Czech Republic over 7 years with a suspected origin in an endemic region and progression of infection through subsequent generations in a non-endemic country exemplifies that this disease may establish itself also in areas where no obvious vectors are present.
