| new approaches to detection and identification of rickettsia africae and ehrlichia ruminantium in amblyomma variegatum (acari: ixodidae) ticks from the caribbean. | imported from africa in the 1700s and despite frequent modern eradication efforts, amblyomma variegatum (f.) spread through the caribbean by cattle transport, small ruminants, and migrating birds. a. variegatum is a vector for rickettsia africae, the causative agent of african tick bite fever, and ehrlichia ruminantium, the causative agent of heartwater. we examined 95 a. variegatum and six rhipicephalus (boophilus) microplus (canestrini) collected from cattle at an abattoir in antigua. engorged ... | 2009 | 19645301 |
| investigation of tick-borne bacteria (rickettsia spp., anaplasma spp., ehrlichia spp. and borrelia spp.) in ticks collected from andean tapirs, cattle and vegetation from a protected area in ecuador. | ixodid ticks play an important role in the transmission and ecology of infectious diseases. information about the circulation of tick-borne bacteria in ticks is lacking in ecuador. our aims were to investigate the tick species that parasitize andean tapirs and cattle, and those present in the vegetation from the buffer zone of the antisana ecological reserve and cayambe-coca national park (ecuador), and to investigate the presence of tick-borne bacteria. | 2015 | 25616567 |
| anaplasma phagocytophilum infection in domestic animals in ten provinces/cities of china. | a nationwide epidemiologic investigation of domestic animal infections has been conducted in nine provinces and one city during 2007-2010. serum samples from a total of 707 goats, 433 cattle, and 219 dogs were collected for detecting anaplasma phagocytophilum igg antibody by immunofluorescence assays and the average seroprevalences were 10.05% for dogs, 3.82% for goats, and 0.69% for cattle, respectively. a total of 472 goats, 201 cattle, 102 dog blood clots, and 1,580 ticks were collected for p ... | 0 | 22764312 |
| molecular detection of anaplasma spp. in pangolins (manis javanica) and wild boars (sus scrofa) in peninsular malaysia. | anaplasma spp. infects a wide variety of wildlife and domestic animals. this study describes the identification of a novel species of anaplasma (candidatus anaplasma pangolinii) from pangolins (manis javanica) and anaplasma bovis from wild boars (sus scrofa) in malaysia. based on 16s rrna gene sequences, candidatus anaplasma pangolinii is identified in a distinct branch within the family anaplasmataceae, exhibiting the closest sequence similarity with the type strains of anaplasma bovis (97.7%) ... | 2016 | 27523941 |
| molecular survey and sequence analysis of anaplasma spp. in cattle and ticks in a malaysian farm. | this study was conducted to determine the occurrence of anaplasma spp. in the blood samples of cattle, goats, deer and ticks in a malaysian farm. using polymerase chain reaction (pcr) and sequencing approach, anaplasma spp. was detected from 81(84.4%) of 96 cattle blood samples. all blood samples from 23 goats and 22 deer tested were negative. based on the analysis of the anaplasma partial 16s ribosomal rna gene, four sequence types (genotypes 1 to 4) were identified in this study. genotypes 1-3 ... | 2014 | 25776603 |
