BACKGROUND To better understand the epidemiology of tick-borne disease in Mongolia, a comprehensive seroprevalence study was conducted investigating exposure to Anaplasma spp. and spotted fever group (SFG) Rickettsia spp. in nomadic herders and their livestock across three provinces from 2014 to 2015. METHODS Blood was collected from 397 herders and 2370 livestock, including sheep, goats, cat...

OBJECTIVE We report a rare case of a 51-year-old woman with ocular and nasal infestation by Oestrus ovis. METHOD Clinical case report and review of current literature regarding nasal and ophthalmomyiasis. RESULTS Myiasis is infestation of the tissues and organs of vertebrates by certain dipteran fly larvae. Oestrus ovis myiasis is endemic in the region from North Africa to South Asia, but f...

this study was conducted to determine the electrophoretic pattern of serum protein in goats infected withbabesia ovis. serum total protein was calculated and serum electrophoresis from 15 goats naturally infectedwith b. ovis as well as same number of healthy goats was performed. microscopic examination of giemsastained peripheral blood smears revealed b. ovis infection. the parasitological diag...

Blood samples collected from wild deer in Missouri in November of 2000 and 2001 were positive by PCR assays for Ehrlichia chaffeensis (50 of 217; 23%), Ehrlichia ewingii (44 of 217; 20%), and Anaplasma species (214 of 217; 99%). Nucleotide sequences of selected amplicons from the assay for anaplasma matched sequences of the white-tailed deer agent. Serologic analysis of 112 deer sampled in 2000...

Myiasis is the infestation by dipterous larvae. The larvae can infect intact or decaying tissue including the skin or epithelial surfaces of the orbits, nose, and genitourinary and gastrointestinal tracts. We report a case of primary obligatory nasal myiasis by Oestrus ovis in a 56-year-old man from Cusco in Peru. He presented with nasal pruritus, congestion, and sneezing white "cottony" materi...

Multiple determinants have been hypothesized to cause or favor disease outbreaks among free-ranging bighorn sheep (Ovis canadensis) populations. This paper considered direct and indirect causes of mortality, as well as potential interactions among proposed environmental, host, and agent determinants of disease. A clear, invariant relationship between a single agent and field outbreaks has not y...

Anaplasma marginale and A. phagocytophilum are intracellular rickettsial pathogens causing bovine anaplasmosis and human granulocytic anaplasmosis, respectively. Effective vaccines for the control of anaplasmosis are not available despite attempts using different approaches, such as attenuated strains, infected erythrocyte and tick cell-derived purified antigens. Recent reports demonstrated tha...

Anaplasma and Ehrlichia species are important tick-borne pathogens that cause disease in cattle, dogs, horses and humans; with little information available about these agents in Colombia. The aim of this study was to provide molecular evidence for the presence of Anaplasma sp. and Ehrlichia sp. species in ticks collected from horses, dogs and cattle in Cordoba, Colombia. In this study, 1.105 ti...
