Theileria parasites infect a wide range of domestic and wild ruminants worldwide, causing diseases with varying degrees of severity. A broad classification, based on the parasite's ability to transform the leukocytes of host animals, divides Theileria into two groups, consisting of transforming and non-transforming species. The evolution of transforming(More)
Equine piroplasmosis represents a serious problem in horse industry. Although, researchers suggested the possible use of sub-unit vaccines to control equine piroplasmosis, the genetic diversity of vaccine candidate antigens was not properly investigated. In the present study, we screened 250 horses reared in three different districts of Tov province,(More)
Here we report on an epidemiological study regarding the molecular prevalence of different genotypes of Theileria orientalis present among domestic cattle and water buffalo populations bred in Thailand. A phylogenetic analysis based on the parasitic gene encoding a major piroplasm surface protein revealed the presence of 5 genotypes (Types 1, 3, 5, 7, and(More)
The apicoplast housekeeping machinery, specifically apicoplast DNA replication, transcription, and translation, was targeted by ciprofloxacin, thiostrepton, and rifampin, respectively, in the in vitro cultures of four Babesia species. Furthermore, the in vivo effect of thiostrepton on the growth cycle of Babesia microti in BALB/c mice was evaluated. The(More)
Nerolidol is a sesquiterpene present in the essential oils of many plants, approved by the U.S. FDA as a food flavoring agent. Nerolidol interferes with the isoprenoid biosynthetic pathway in the apicoplast of P. falciparum. In the present study, the in vitro growth of four Babesia species was significantly (P<0.05) inhibited in the presence of nerolidol(More)
Anaplasma marginale has been detected in the Philippines only by peripheral blood smear examination and serological methods. This study generally aimed to molecularly detect and characterize A. marginale in cattle and ticks in Cebu, Philippines. A total of 12 bovine blood samples and 60 Rhipicephalus (Boophilus) microplus ticks were collected on the Cebu(More)
In vitro evaluation of chemotherapeutic agents against Babesia and Theileria parasites has become routine, and the effectiveness of these chemicals is usually determined by comparing the parasitemia dynamics of untreated and treated parasites. Although microscopy is widely used to calculate parasitemia, several disadvantages are associated with this(More)
Vector-borne diseases (VBDs) continue to threaten the worldwide livestock industry, but comprehensive epidemiological surveys on such diseases have not been conducted in the Philippines. In the present study, we screened 408 bovine blood samples from 9 areas in Cebu, Philippines, for various VBD pathogens using specific PCR assays. The results revealed(More)
Bovine babesiosis is an economically significant disease that affects dairy farming operations in Thailand. In the present study, 1824 blood-DNA samples prepared from cattle bred in 4 different regions of the country (North, Northeast, Central, and South) were screened using a nested PCR for the specific detection of Babesia bovis. While the overall(More)
A truncated fragment of the gene encoding the 200-kDa protein (P200) of Babesia bigemina was cloned into a plasmid vector, pGEX-4 T-1 and expressed in Escherichia coli as a glutathione-S-transferase fused protein. An indirect enzyme-linked immunosorbent assay (ELISA) using the rp200/CT detected specific antibodies in cattle experimentally infected with B.(More)
