The ixodid Amblyomma aureolatum is suspected to play a role in the epidemiology of wild life-cycle hemoparasites, which frequently infect dogs in rural and hunting areas in Brazil. Little is known about its bionomics. The objective of the present study was to evaluate some bionomic aspects of A. aureolatum ticks in Brazil. One engorged female, collected from a dog (Canis familiaris) in São Seba...

BACKGROUND Babesia spp. are tick-borne protozoan hemoparasites and the second most common blood-borne parasites of mammals, in particular domestic animals. We used the Clustal Multiple Alignment program and 18S rRNA gene sequences of 22 Babesia species from GenBank to develop a PCR that could detect a wide variety of Babesia spp. in a single reaction. The pan-Babesia FRET-qPCR we developed reli...

BACKGROUND The Gila monster (Heloderma suspectum), one of several venomous lizard species in the world, is found within the United States and Mexico and is recognized as an iconic symbol of the American Southwest. Thus, Gila monsters are of growing interest in the captive reptile trade and within zoological and educational institutions. OBJECTIVES The aims of this study were to determine resu...

Babesia bovis and Babesia bigemina are tick-borne hemoparasites causing babesiosis in cattle worldwide. This study was aimed at providing information about the occurrence and geographical distribution of B. bovis and B. bigemina species in cattle from Gauteng province, South Africa. A total of 268 blood samples collected from apparently healthy animals in 14 different peri-urban localities were...

Hemoparasites of the apicomplexan family Plasmodiidae include the etiological agents of malaria, as well as a suite of non-human primate parasites from which the human malaria agents evolved. Despite the significance of these parasites for global health, little information is available about their ecology in multi-host communities. Primates were investigated in Kibale National Park, Uganda, whe...

A rapid and accurate assay for evaluating antibabesial drugs on a large scale is required for the discovery of novel chemotherapeutic agents against Babesia parasites. In the current study, we evaluated the usefulness of a fluorescence-based assay for determining the efficacies of antibabesial compounds against bovine and equine hemoparasites in in vitro cultures. Three different hematocrits (H...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 33-year-old man presented with left hypochondrium pain and high-grade fever for 1 week and generalized convulsions followed by persistent unconsciousness. 2.8 mg/dL. His coagulation profile showed an international normalized ratio of 2.4, along with severe...

Surveys for disease agents were conducted in introduced free-ranging elk (Cervus elaphus nelsoni) in Arkansas and Kentucky. Elk had been captured in Colorado and Nebraska and released in Arkansas during 1981-1985. From 1997 through 2002 elk were captured in Arizona, Kansas, North Dakota, New Mexico, Oregon, and Utah and released in southeastern Kentucky. Specimens were collected from 170 hunter...
