There are 16 recognized species of avian-infecting Babesia spp. (Piroplasmida: Babesiidae). While the classification of piroplasmids has been historically based on morphological differences, geographic isolation and presumed host and/or vector specificities, recent studies employing gene sequence analysis have provided insight into their phylogenetic relationships and host distribution and spec...

The genera Babesia and Theileria (phylum Apicomplexa, order Piroplasmida) are mainly transmitted by Ixodid ticks in which the sexual part of their life cycle followed by sporogony takes place. They include protozoan parasites that infect erythrocytes of a variety of vertebrate hosts, including domestic and wild animals, with some Babesia spp. also infecting humans. Babesia sporozoites transmitt...

OBJECTIVES The aim of this clinical assessment was to ascertain whether a 70-year-old Canadian patient, who had no history of out-of-country travel, had contracted a Babesia infection. METHODS The adult human male developed constitutional symptoms, which included sweats, chills, and immobilizing fatigue, and was screened for human babesiosis. Subsequent testing included a complete Babesia pan...

Background. Canine babesiosis is a clinically important hemoprotozoan parasite affecting dogs. The goal of this present study was to determine the clinical symptoms and to establish its hematological and microscopic detection and compare it with the PCR findings attained from dogs infected with Babesia canis vogeli. Methodology/Principal Findings. 13-PCR confirmed Babesia-infected dogs were exa...

The prevalence of Babesia spp. infection was studied in sheep of the Mashhad area in Iran from 1998 to 2000. A total of 677 sheep originating from 115 flocks were clinically examined and investigated for the presence of Babesia spp. in appropriate blood smears and any tick species on the body of the animals. The study revealed that the infection rate for Babesia ovis and Babesia motasi were 167...

Tick-borne diseases are considered as emerging infectious diseases in humans and animals in China. In this study, Ixodes persulcatus (n = 1699), Haemaphysalis concinna (n = 412), Haemaphysalis longicornis (n = 390), Dermacentor nuttalli (n = 253), and Dermacentor silvarum (n = 204) ticks were collected by flagging from northeastern China, and detected for infection with Anaplasma, Ehrlichia, Ba...

background: equine piroplasmosis (ep) is the cause of persistent tick-borne infection with no symptoms, but the most important problem of ep is due to the persistent carrier state. carrier animals to babesia ( theileria ) equi (laveran 1901) and b. caballi (nuttall, 1910) infestation could be identified by extremely sensitive pcr-based method. the purpose of this study was to identify the causa...

Infection with Babesia microti has not been well-described in eastern Pennsylvania, USA, despite the vector of this organism being prevalent. We report 3 cases of babesiosis in eastern Pennsylvania in persons without recent travel outside the region or history of blood transfusions, suggesting emergence of this infection.

canine babesiosis is an important worldwide, tick-born disease caused by apicomplexan hemoparasitic from genus babesia. the aim of the present survey was to identify the current state of babesia infection in urban and rural dogs in ahvaz district, southwest of iran. for this reason, 200 rural dogs from 5 village around ahvaz and 200 urban dogs (stratified random sampling) referred to the vet...

Four chemotherapeutic trials in Iran with the babesicide 3,3-bis(2-imidazoline-2-yl) carbanilide dihydrochloride (Imidocarb dihydrochloride) are reported. Subcutaneous administration at a dose of l mg/kg proved highly effective in controlling experimental infection with a local virulent strain of Babesia bigemina in calves. While treated calves were apparently sterilized of the infection, they ...
