The Camel Tick, Hyalomma (Hyalomma) dromedarii Koch, 1844 (Ixodoidea: Ixodidae): Description of the Egg and Redescription of the Larva by Scanning Electron Microscopy

Catalase from larvae of the camel tick Hyalomma dromedarii

Catalase plays a major role in protecting cells against toxic reactive oxygen species. Here, Catalase was purified from larvae of the camel tick Hyalomma dromedarii and designated TLCAT. It was purified by ammonium sulfate precipitation and chromatography on DEAE-cellulose, Sephacryl S-300 and CM-cellulose columns. Gel filtration and SDS-PAGE of the purified TLCAT indicated that the protein has...

Redescription of the larva of Amblyomma oblongoguttatum Koch, 1844 (Acari: Ixodidae) by light and scanning electron microscopy

The larval stage of Amblyomma oblongoguttatum Koch is redescribed using optical and scanning electron microscopy. Unfed larvae were obtained from a colony of A. oblongoguttatum originated from engorged females collected on domestic pigs from Monte Negro municipally (10°29’S, 63°32’W), State of Rondônia, Western Amazon, Brazil. Several characters are presented including the chaetotaxy of the idi...
