| the epidemiology of tropical theileriosis (theileria annulata infection in cattle) in an endemic area of morocco. | a longitudinal study of tropical theileriosis was performed on 12 farms in the doukkala region of morocco during 1990. adult hyalomma detritum detritum were collected between march and early october and a peak in numbers was observed at the end of june. nineteen percent (24/127) were infected with theileria species and, amongst these, over 50% had five or more sporoblasts in their salivary glands (range 1-151). hyalomma d detritum larvae and nymphs were found on cattle between september and earl ... | 1992 | 1441192 |
| prevalence of theileria in the tick hyalomma detritum detritum in the doukkala region, morocco. | the overall prevalence of theileria species, mainly, if not exclusively, t.annulata, in 901 hyalomma detritum detritum collected from cattle in the doukkala region of morocco over a period of 2 years was 21.5%. the quantity of infection (number of sporoblasts per infected tick) followed the negative binomial distribution with between one and 250 sporoblasts per infected tick. infected ticks were found in eight of fourteen areas examined whilst t.annulata was present in all fourteen. there were s ... | 1993 | 8268489 |
| distribution and ecology of ticks (acari: ixodidae) infesting livestock in tunisia: an overview of eighth years field collections. | ticks (ixodidae) play a significant role as vectors of pathogens of domestic animals in tunisia. the major losses caused by ticks are related to transmission of protozoan parasites. these include agents of tropical theileriosis and babesiosis in ruminants. since 1991, we conducted research studies on tick population of livestock in tunisia. this overview reports a synthesis on tick distribution, their biology and their role as vectors of pathogens in domestic animals, particularly cattle. during ... | 1999 | 11071534 |
| ticks status in central asia with a special emphasis on uzbekistan. | uzbekistan is located between the greatest rivers of central asia and shares borders with kazakhstan to the west and to the north, kyrgyzstan and tajikistan to the east, and afghanistan and turkmenistan to the south. the climate is severely continental and arid, with hot summers and cold winters. these climatic particularities of uzbekistan determine the distribution of tick fauna. the ixodidae family of ticks is represented by 23 species in uzbekistan. these ticks, as ectoparasites, cause signi ... | 2007 | 17823825 |
