Babesia hylomysci and B. divergens were studied for superoxide dismutase (SOD) activity by enzyme assay and isoelectric focusing (IEF). In the two Babesia species, parasite-associated SOD is cyanide-insensitive and inhibited by H2O2, indicating that iron is the cofactor metal. Measurements of SOD activity from purified parasites show that the SOD activity detected in Babesia is, for the main pa...

BACKGROUND Human babesiosis is a rare tick-borne infectious disease. The clinical presentation ranges from an asymptomatic form to a life threatening infection with severe hemolysis. Human babesiosis due to Babesia microti is the most common and is endemic in North America. CASE PRESENTATION We report a European patient with severe pancytopenia and reactive hemophagocytosis related to a Babes...

Developmental forms of Babesia spp. were studied in isolated salivary glands of Ixodes ricinus, subjected to the Feulgen reaction. The same ticks were also hosts to Babesia microti, which was determined by PCR amplification with primers specific to the fragment of a gene encoding the nuclear small sub-unit ribosomal RNA (SS-rDNA). Presence of Babesia spp. was recorded in the salivary glands of ...

Ticks are potent vectors of many deadly human and animal pathogens. Tick-borne babesiosis is a well-recognized malaria-like disease that occurs worldwide and recently has attracted increased attention as an emerging zoonosis. Although the proliferation of Babesia organisms is essential in the vectors, their detailed lifecycle with time information for migration in ticks remains unknown. A novel...

Babesiosis is an emerging zoonosis with important public health implications, as the incidence of the disease has risen dramatically over the past decade. Because the current gold standard for detection of Babesia is microscopic examination of blood smears, accurate identification requires trained personnel. Species in the genus cannot be distinguished microscopically, and Babesia can also be c...

We report the first molecular evidence of the presence of Babesia sp. EU1 and Babesia microti in Ixodes ricinus ticks in Belgium. A 1-year national survey collected 1005 ticks from cats and dogs. A polymerase chain reaction technique amplifying a part of the 18S rRNA gene detected Babesia spp. in 11 out of 841 selected and validated tick extracts. Subsequent sequencing identified Ba. microti (n...

The partial DNA sequences of the 18S rRNA gene of Babesia canis and the 16S rRNA gene of Ehrlichia canis detected in dogs from Ribeirão Preto, Brazil, were compared to sequences from other strains deposited in GenBank. The E. canis strain circulating in Ribeirão Preto is identical to other strains previously detected in the region, whereas the subspecies Babesia canis vogeli is the main Babesia...

background: ovine babesiosis is the most important haemoparasitic tick-borne disease of small ruminants in iran caused by babesia ovis, b. motasi, and b. crassa . the aim of this study was to characterize the species of ovine babesia species isolated from different geographical region of iran. methods: one hundred fifty four blood samples collected from animals, which demonstrated the pale muco...

Equine piroplasmosis is a tropical parasitic disease caused by several intraerythrocytic members of the genera Babesia and Theileria. These pathogens are transmitted multiple tick species considered as important exotic microorganisms in countries. causes significant economic losses due to abortions, decreased activity even death equines, making surveillance these infectious essential. In northe...

altogether, 132 rodents of 4 species of meriones persicus , cricetulus migratorius, mus muscri~ius and allactaga dater were collected with live traps from different parts of meshkin - shahr district from summer 1373 to autumn 1374. the purpose of this survey was to identify the parasitic fauna of rodents. before dissection, the mammals were measured for biometric purposes. babesia microti , see...
