Linda’s comment:  It is nice to see more Vets are getting involved with Lyme and pets….

Excerpt:

The present study describes the only deer
piroplasm detected so far that shows complete identity with B. divergens, in
just over half of the 18S rRNA gene. The entire gene of this deer parasite
should be analysed and transmission experiments undertaken before the
infectivity of B. divergens for red deer can be confirmed.

Linda’s comment:   Single ticks were investigated by polymerase chain reaction and restriction
fragment length polymorphism or sequencing for Borrelia spp. (ospA gene) and Babesia spp. (18S rRNA gene). Overall, 27.0% (270/1000) were infected with Borrelia species. Out of these, Borrelia garinii was detected most frequently.  Now what is it going to take to get more doctors educated on this?  Lyme disease has become a world-wide epidemic, which the CDC and IDSA refuse to recognize….<sigh>

Excerpt:

Babesia
spp.-specific DNA was detected in 5.0% of ticks. Babesia microti
was slightly more prevalent
(28/50) than Babesia divergens (20/50). Moreover, 5.9% (16/270)
of Borrelia spp.-infected ticks were coinfected with Babesia spp.
Knowledge on the degree of heterogeneity of Borrelia species and
OspA types is prerequisite not only for local risk assessment,
but also for diagnostic test and vaccine development.

Tick-borne pathogens such as Lyme borreliosis spirochaetes,
Anaplasma phagocytophilum, Rickettsia spp. and Babesia spp. cause
a great variety of diseases in animals and humans. Although their
importance with respect to emerging human diseases is increasing,
many issues about their ecology are still unclear. In spring
2007, 191 Ixodes ricinus (Acari: Ixodidae) ticks were collected
from 99 birds of 11 species on a bird conservation island in the
Baltic Sea in order to test them for Borrelia spp., A.
phagocytophilum, Rickettsia spp. and Babesia spp. infections.
Identification of the pathogens was performed by polymerase chain
reaction (PCR), restriction fragment length polymorphism and
sequence analysis. The majority of birds with ticks testing
positive were European robins and thrushes. Borrelia DNA was
detected in 14.1%, A. phagocytophilum in 2.6%, rickettsiae in
7.3% and Babesia spp. in 4.7% of the ticks. Co-infections with
different pathogens occurred in six ticks (3.1%). The fact that
11 ticks (five larvae, six nymphs) were infected with Borrelia
afzelii suggests that birds may, contrary to current opinion,
serve as reservoir hosts for this species. Among rickettsial
infections, we identified Rickettsia monacensis and Rickettsia
helvetica. As we detected five Rickettsia spp.
positive larvae and two birds carried more than one infected
tick, transmission of those pathogens from birds to ticks appears
possible.

Excerpt:

We report an unusual case of human babesiosis in Finland in a
53-year-old man with no history of splenectomy. He had a
rudimentary spleen, coexisting Lyme borreliosis, exceptional dark
streaks on his extremities, and subsequent disseminated
aspergillosis. He was infected with Babesia divergens, which
usually causes bovine babesiosis in Finland.
