Resistance status of ticks (Acari; Ixodidae) to amitraz and cypermethrin acaricides in Isoka District, Zambia
TLDR
Modified larval packet test (LPT) bioassay experiments were used to determine the resistance status of the common tick species against amitraz and cypermethrin acaricides and indicated that resistance toAmitraz was developing in R. (Bo.) microplus. Expand
First report of heartwater (cowdriosis) in Kafue lechwe (Kobus leche kafuensis) in Zambia
TLDR
La cowdriose a été diagnostiquée chez des antilopes de Kafue (Kobus leche kufuensis) transférées dans leur région, sur la base des symptômes cliniques, d’autopsie and d‘examens de laboratoire, en Zambie. Expand
Monitoring of naturally acquired and artificially induced immunity toAmblyomma variegatum andRhipicephalus appendiculatus ticks under field and laboratory conditions
TLDR
The ability of rabbits, goats and cattle to acquire immunity to the ixodid ticksAmblyomma variegatum andRhipicephalus appendiculatus was studied under laboratory and field conditions and strong skin reactions were noticed when adults ticks fed on immunized goats. Expand
Mapping the Geographical Distribution of Lymphatic Filariasis in Zambia
TLDR
LF was found to be surprisingly widespread in Zambia, although in most places with low prevalence, and areas associated with human modification of the landscape appeared to play an important role for the general presence of LF, whereas temperature seemed to be an important determinant of medium-high prevalence levels. Expand
Biology of Rhipicephalus appendiculatus and R. zambeziensis and production of a fertile hybrid under laboratory conditions.
TLDR
The adults of both species showed preference for the bovine host and performed better at the end of the rainy season, and detailed field studies will have to be performed in order to gain knowledge on population dynamics, interbreeding and the vector role of the two species and their hybrids under field conditions. Expand
Ehrlichia ruminantium, Sudan
TLDR
Ehrlichia ruminantium, the causative agent of heartwater, is transmitted by Amblyomma variegatum ticks, which are found in the Caribbean and sub-Saharan Africa, except in certain areas of southern Africa, and its distribution and epidemiologic data exist on infection rates. Expand
Morphogenetic diapause in Amblyomma variegatum (Acari: Ixodidae)
TLDR
Females exposed in a natural environment in September‐October (short day) had significantly longer pre‐oviposition periods than females exposed from November to March, and artificial changes in photoperiod during and after female engorgement had no significant effects on pre-ovipposition periods. Expand
Delayed-type hypersensitivity test for assessing tick-immune status of cattle in Zambia
TLDR
There was a significant negative correlation between the intensity of the reactions and the total number of ticks on the animals and a homogenate of unfed nymphal Rhipicephalus appendiculatus which had been shown to give protective immunity in guinea pigs to adult female R appendicULatus was used. Expand
Biology ofRhipicephalus appendiculatus andR. zambeziensis and production of a fertile hybrid under laboratory conditions
TLDR
Detailed field studies will have to be performed in order to gain knowledge on population dynamics, interbreeding and the vector role of the two species and their hybrids under field conditions, as well as to clarify the taxonomic status of the intermediate forms. Expand
