“…A. persicus sensu stricto is a Palaearctic species which parasitises a variety of economically important poultry species with which it has spread to many parts of the world (Hoogstraal 1985). Heavy infestations can lead to irritation, restlessness, reduced productivity due to blood loss and can be lethal through exsanguination, (Roberts 1952;Hoogstraal 1985;El Kammah et al 2002). Tick paralysis in fowl can be caused by the larvae (Rosenstein 1976; Gothe et al 1981b).…”

Argas persicus sensu stricto does occur in Australia

The status of Argas persicus in Australia has been a matter of controversy for over 25 years. Although early records of A. persicus sensu stricto are common, a major revision of the genus indicated that these records refer to A. robertsi, first described in 1968 from northern Australia, and to an "undescribed" member of the complex occurring in the south. Here, we show that A. persicus sensu stricto does occur in southern Australia and is the only species of Argas in the area recorded from poultry. Another undescribed species belonging to the A. persicus complex, from crows' nests near Lake Eyre in South Australia, was also discovered. This information is of considerable epidemiological significance, as A. persicus sensu stricto is a major vector for a number of highly pathogenic diseases of poultry, not all of which have yet been recorded from Australia.

In this investigation on endoparasites (helminths) and ectoparasites of the Nile rat (Arvicanthis niloticus Desmarest, 1822), a total of 220 Nile rats were trapped from different regions of Sudan during the period January 2003-January 2006. Examination of different tissues, identification of parasites, effect of these parasites on the organs, the prevalence and intensity of infestation of the parasites and their relation to the habitat of the host, and sex-related infestations were considered. Results showed that the variation among helminth species was wide, especially in those that are transferred by arthropods. No protozoan parasites or distortion in the infected tissues were observed. No examination for Toxoplasma gondii was carried out. Two species of cestodes (Hymenolepis nana, Hymenolepis diminuta), two genera (Raillietina sp. I, Raillietina sp. II) and one unidentified Hymenolepididae were reported. The most prevalent species of cestodes was Raillietina sp. And for nematodes only one species and one genus were recovered (Monanema nilotica and Streptopharagus sp.). Investigation of skin revealed that 83.8% of rats were infested with one or more of ectoparasites; namely, insects and arachnids. This survey also revealed that fleas and lice were the most common ectoparasites that infested the Nile rat. Synanthropic rodents, particularly those living in close association with man, play a significant role in human health, welfare and economy. It has to be stressed that their arthropod ectoparasites are important vectors of pathogenic microorganisms and they can also be important reservoirs for parasitic zoonoses, like trichinellosis and capillariosis. No doubt, the increase in rodent populations could be followed by an increase in zoonotic diseases (Stojcevic et al. 2004, Durden et al. 2000. Rats and mice (commensal and wild) play an important role in public health, being carriers or reservoirs for infectious diseases that can be transmitted to humans (zoonoses). Xenopsylla cheopis is the most important vector of plague and the rickettsial infection murine typhus (Gratz 1999). Man can also acquire the infection through direct contact with infected animals' tissues (WHO 1987). Arvicanthis niloticus, Mastomys natalensis and Rattus rattus are probably the most important and widespread reservoirs of plague in Kenya: 10 percent of all Rattus rattus tested were found to be positive as compared to 12% of the Arvicanthis niloticus (Gratz 1999).

Studies were conducted into the development of anti-tick vaccines against two tick species, namely Boophilus annulatus Say, 1821 and Argas persicus (Oken) 1818, which, respectively, are responsible for high economic losses in the cattle and chicken industries in Egypt. Repeated infestation of spring chicken with Argas persicus females stimulated 35.9 % resistance to tick feeding compared to 20.4 % in controls. This resistance was associated with the presence of antibody activity to tick salivary gland antigens. There was increase of both the chicken serum total protein and the number of protein bands separated by SDS-PAGE, which suggested an increase in immunoglobulins. Chicken resistance to tick feeding was also induced by repeated injection (vaccination) with crude Argas persicus salivary gland antigens, with intramascular injection being more efficient at inducing immunity than subcutaneous injection.Prolonged infestation with Boophilus annulatus ticks induced immunity in cattle. Salivary gland and gut crude extracts of cattle exposed to the ticks contained antigenic proteins, with dominant 66 and 150 KDa glycoproteins. Antibodies against the two extracts or PAGE-separated antigens were detected in cattle that resisted tick feeding. Cell-mediated immunity (CMI) was also detected. The immune response was strong in non-infested Bos indicus and Bos indicus x Bos taunts Linneaeus, 1766 crossbreeds with low infestation, and weak in heavily infested Bos taurus.Resume-Des etudes ont ete menees pour la mise au point de vaccins anti-tiques contre deux especes de tiques, Boophilus annulatus Say, 1821 et Argas persicus (Oken) 1818, qui sont responsables respectivement de pertes economiques importantes dans la production de bovins et de poulets en Egypte. Des infestations repetees de poussins avec des femelles d'Argas persicus stimulent la resistance aux repas des tiques (35,9%) compart aux temoins (20,4%). Cette resistance est associee a la presence d'anticorps contre les antigenes des glandes salivaires de tiques. On observe a la fois une augmentation des proteines totales du serum des poussins et du nombre de bandes proteiniques separees par SDS-PAGE, ce qui suggerent une augmentation des immunoglobulines. La resistance des poussins aux repas des tiques est egalement induite par des injections repetees (vaccination) d'extraits bruts d'antigenes de glandes salivaires d'Argas persicus. Les injections intramusculaires induisent plus efficacement l'immunite que les injections souscutanees.Des infestations prolonge'es avec des tiques de l'espece Boophilus annulatus induisent une immunity du betail. Les extraits bruts de glande salivaire et d'estomac de bovins exposes aux tiques contiennent
