| the distribution of rickettsia in the tissues of insects and arachnids. | in the absence of a satisfactory definition of rickettsia the observations herein recorded were arbitrarily limited to bacterium-like organisms which are intracellular and gram-negative. rickettsia of this type were found in the following species: amblyomma americana, amblyomma hebraeum, boophilus decoloratus, atomus sp., casinaria infesta, chrysopa oculata, ctenocephalus canis, dermacentor variabilis, lepisma saccharina, lucoppia curviseta, margaropus annulatus, margaropus annulatus australis, ... | 1923 | 19868737 |

| 2,6-dichlorophenol, sex pheromone of the lone star tick. | the compound 2,6-dichlorophenol was identified from female lone star ticks, amblyomma americanum, and is believed to be a sex pheromone of this arthropod. the natural occurrence of a chlorinated organic compound in a land animal is new. the presence of similar compounds of exogenous origin is common in animals, but efforts to implicate an outside source for the halogenated phenol have failed. | 1972 | 5054146 |

| a search for the epidemic typhus agent in ethiopian ticks. | the presence of antibodies to rickettsia prowazeki in domestic animals from several parts of africa, and the isolation of this rickettsia from the blood of goats and sheep and from ticks off cattle or camels in ethiopia, led to the hypothesis that r. prowazeki in nature may occur in an extrahuman cycle involving ticks and domestic animals. this study attempted to recover r. prowazeki from 2 624 ticks (4 genera, 10 species) collected in central and southern ethiopia. the ticks were examined by th ... | 1973 | 4204491 |

| development of theileria mutants (aitong) in the tick amblyomma variegatum compared to that of t. parva (muguga) in rhipicephalus appendiculatus. | a comparison was made between the development of theileria mutans (aitong) in adult amblyomma variegatum ticks and the development of t. parva (muguga) in adult rhipicephalus appendiculatus ticks. both batches of ticks dropped as engorged nymphs from cattle whose intraerythrocytic parasitemias were approximately 40%, and it was thus possible to make a direct comparison of the infection rates produced in their tick hosts in this experiment by the 2 species of theileria. ticks of the 2 batches wer ... | 1975 | 809568 |

| studies on theileriidae (sporozoa) in tanzania. i. tick transmission of haematoxenus veliferus. | haematoxenus veliferus was experimentally transmitted in cattle on two occasions by the tick amblyomma variegatum; transmission was transstadial, from nymph to adult. theileria mutans and cowdria ruminatium were transmitted at the same time. h. veliferus infected at least 15% of red cells in a splenectomized steer and 10% in a normal steer. one experiment on transstadial transmission from larva to nymph was unsuccessful. | 1976 | 1258136 |

| studies on theileriidae (sporozoa) in tanzania. v. preliminary experiments on a new method for infecting ticks with theileria parva and theileria mutans. | bovine blood with a high parasitaemia of theileria mutans was injected through the cuticle into fully engorged nymphs of amblyomma variegatum which had recently detached from a rabbit. after moulting, they transmitted this parasite to a susceptible calf. rhipicephalus appendiculatus transmitted theileria parva in the same way, but results were negative with a. variegatum and t. parva. this method of infecting ticks appears promising for the isolation of theileria strains from the field, and migh ... | 1976 | 1006800 |
