Ticks infesting cattle represent a serious problem for improvement of cattle productivity in South Sudan. There has been limited information on ticks and tick-borne diseases in southern Sudan. This study was initiated to update the current distribution of ticks infesting cattle in the Central Equatoria region of South Sudan. The surveys for the present study were conducted at various cattle...

Ixodid ticks were collected at weekly intervals from February 1999 to April 2000 from domestic dogs belonging to people in rural communities in north-eastern KwaZulu-Natal. Seven ticks were identified to species level and adult Haemaphysalis leachi followed by immature Amblyomma hebraeum and adult Rhipicephalus simus were the most prevalent. Infestation with adult H. leachi was most intense dur...

Objective. Using the data obtained in Perm Region as an example, to identify effectiveness of polymerase chain reaction (PCR) for diagnosis Human Monocytic Ehrlichiosis (HME) at different periods from onset disease, and determine role HME structure infections transmitted by ixodic ticks using PCR enzyme-linked immunosorbent assay (ELISA)
 Materials methods. A thorough clinical epidemiologi...

Ticks are blood feeding arthropod parasites transmitting a wide variety of pathogens to their vertebrate hosts. The vector capability of ticks is tightly linked to their immune system. Ticks can defend themselves against microbial infection with a variety of antimicrobial peptides comprising lysozymes, defensins, and unique molecules not found in other arthropods. Lysozymes are hydrolytic enzym...

Sixteen experimental burn plot replicates, in groups of four, in four landscape zones of the Kruger National Park, South Africa, and from which wildlife are not excluded, have been subjected to fixed, regular burning regimens since 1954. In 1999, a study to determine the effect of burning on ixodid ticks questing for hosts from the vegetation of the plots was initiated, and six sub-plots, with ...

The purpose of this study was to determine the species spectrum of ticks infesting goats owned by resource-limited farmers in the state-owned communal land areas of Zimbabwe. Ticks were collected from goats at a single locality within each of 5 communal land areas, and a total of 14 ixodid tick species was recovered. The most numerous tick was Rhipicephalus evertsi evertsi, which was present in...
