| natural infection rates and transmission of theileria annulata by hyalomma anatolicum anatolicum ticks in the sudan. | hyalomma anatolicum anatolicum nymphs were collected from two localities in the sudan: eddamer in northern sudan and wad-medani in central sudan. they were allowed to moult to adult ticks, which were assessed for theileria infection in their salivary glands using feulgen stain. at eddamer, 49.6% of 123 ticks examined were infected with theileria and the mean intensity of infection was 1.3 (i.e. the number of infected acini/number of infected ticks). at wad-medani, 8.6% of 162 ticks were infected ... | 2005 | 16562733 |
