Hаematologic indices in clinically healthy outdoor dogs exposed to vector-borne pathogens

Antigenic variation in vector-borne pathogens.

Several pathogens of humans and domestic animals depend on hematophagous arthropods to transmit them from one vertebrate reservoir host to another and maintain them in an environment. These pathogens use antigenic variation to prolong their circulation in the blood and thus increase the likelihood of transmission. By convergent evolution, bacterial and protozoal vector-borne pathogens have acqu...

Study on coinfecting vector-borne pathogens in dogs and ticks in Rio Grande do Norte, Brazil.

Since dogs presenting several vector borne diseases can show none or nonspecific clinical signs depending on the phase of infection, the assessment of the particular agents involved is mandatory. The present study aimed to investigate the presence of Babesia spp., Ehrlichia spp., Anaplasma spp., Hepatozoon spp. and Leishmania spp. in blood samples and ticks, collected from two dogs from Rio Gra...

PCR-based survey of vector-borne pathogens in dogs in Dhaka, Bangladesh

To identify tick-borne pathogens in blood samples from 68 dogs were examined for Babesia, Anaplasma/Ehrichia, Mycoplasma, and Hepatozoon spp. by using a molecular tool. The detection of DNA was performed using specific primers for partial 16S rRNA or 18S rRNA sequence, and amplicon sequences were analyzed. Our investigation detected Babesia gibsoni (26 dogs) and Anaplasma sp. AnHl446 (2 dogs), ...

Prevalence of mastitis pathogens in milk from clinically healthy cows

A total of 669 individual cow milk samples originating from asymptomatic cows from 16 dairy farms were examined for the presence of microorganisms with the potential to cause mastitis. Coagulase-negative staphylococci clearly predominated (53.5% positive samples) followed by streptococci and enterococci (both occurring in 16.1% samples). Among streptococci, so-called mastitis streptococci (S. u...
