Abstract Migratory organisms can be vectors of parasitic host that then transported along seasonal migratory journeys and spread across continents. Ornithophilic nidicolous ticks (e.g. soft ticks) include species responsible for the transmission pathogens bacteria, thus representing a health problem not only wild are directly parasitized, but also those share same environments or reproductive s...
BACKGROUND As obligate blood-feeding arthropods, ticks transmit pathogens to humans and domestic animals more often than other arthropod vectors. Livestock farming plays a vital role in the rural economy of Pakistan, and tick infestation causes serious problems with it. However, research on tick species diversity and tick-borne pathogens has rarely been conducted in Pakistan. In this study, a s...
The epidemiology of vector-borne zoonoses depends on the movement of both hosts and vectors, which can differ greatly in intensity across spatial scales. Because of their life history traits and small size, vector dispersal may be frequent, but limited in distance. However, little information is available on vector movement patterns at local spatial scales, and particularly for ticks, transmitt...
Nuttalliella namaqua is the only species of the enigmatic third tick family. Females possess features of hard and soft ticks and have been designated as the "missing link" between the main tick families. Its position at the base of the tick tree suggests that some of the features unique to hard and soft ticks were present in the ancestral tick lineage. Larvae, nymphae and males have not been de...
Hard ticks (Acari: Ixodidae) are important obligatory blood feeding external parasites of human and animals. There have been a lot of studies on taxonomy of Iranian ixodidae. On the basis of morphological features found basically in adult male. There are problems in tick identification due to their intraspecific variations and morphological changes of the surface body of ticks after blood feedi...
Tick-borne rickettsioses are emerging and re-emerging diseases of public health concern caused by over 30 species Rickettsia . Ticks obligate hematophagous arthropods with 700 Ixodid ticks known worldwide. The escalating geographical dispersal tick vectors concomitant increase in the incidences tick-borne have fueled interest ecology pathogens. This review focuses on aspects pathogen, including...
Anaplasma marginale is a Gram-negative, obligate intraerythrocytic bacterium that causes bovine anaplasmosis. While hard ticks of the genera Dermacentor and Rhipicephalus can be biological vectors, transmitting this pathogen via saliva during blood meals, blood-sucking insects, fomites play role as mechanical vectors. Little known about interaction between Argasidae ticks. Among soft ticks, Orn...
