Haemogregarines were recorded in caimans Caiman crocodilus yacare from Pantanal. This study was carried out in seasonal ponds at the Miranda- Abobral subregion of Pantanal, State of Mato Grosso do Sul, western Brazil, from 1998 to 1999. Smears from 28 caimans were examined and 20 (71.4%) presented infection by a haemogregarine. Infections were observed in 11 males and 9 females. Morphological a...

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...

Life cycles and molecular data for terrestrial haemogregarines are reviewed in this article. Collection material was re-examined: Hepatozoon argantis Garnham, 1954 in Argas brumpti was reassigned to Hemolivia as Hemolivia argantis (Garnham, 1954) n. comb.; parasite DNA was extracted from a tick crush on smear of an archived slide of Hemolivia stellata in Amblyomma rotondatum, then the 18S ssrRN...

This study aimed to detect Hepatozoon spp. in ticks infesting asymptomatic domestic animals and provide insight into their potential spillover from wild animals. In total, 537 tick specimens were collected Khyber Pakhtunkhwa, Pakistan, morphologically identified. The most prevalent species was Haemaphysalis cornupunctata (69; 12.8%), followed by kashmirensis (62; 11.5%), Rhipicephalus microplus...

Blood samples were collected from 99 domestic dogs from the urban and rural areas of the Lábrea municipality, state of Amazonas, Brazil. Canine serum samples were tested by immunofluorescence assay against Rickettsia spp., which revealed that only 3.0% (1/33) and 7.6% (5/66) of the dogs from urban and rural areas, respectively, reacted positively to at least one Rickettsia species. DNA was extr...

Limited information on the presence of bacterial and hematozoan infections in parasitic arthropods from Spain is available. In an attempt to address this issue, the prevalence of Theileria, Babesia, Hepatozoon, and Rickettsia species was investigated by polymerase chain reaction plus sequencing. In a survey for zoonotic pathogens in ectoparasites, 42 wild animals (which included rodents, carniv...
