“…The results and discussion of the present study show that the appearance, persistence, IR and no. of the spirochete varied in the different organs examined which conform with other previous investigations (Varma, 1962;Balashov, 1972;Zaher et al, 1977, andGaber et al, 1984). It was suggested (Burgdorfer, 1951), and experimentally demonstrated (Sarsian, 1959, andGrun &Blatter, 1960) that chemotropic factors induce microorganisms to migrate and to localize in tick tissues.…”

“…Furthermore, localization of the spirochete in the ovaries may help in recognizing the specificity of the tick species as a vector of a certain B. species particularly in ornithodorine and some argasid ticks (Balashov, 1972& Hoogstraal, 1985. Experimental infection of some argasid Zaher et al, 1977) and of some ornithodorine (Gaber et al, 1984 andShanbaky &Helmy, 2000) tick species with borreliae species isolated from other tick vectors resulted in failure of localization of the spirochetes in the gonads and transovarial transmission in the unnatural recipients.…”

“…Based on a morphological approach of immature and mature stages, taxonomic summaries of this genus have proposed to divide most of its specific diversity in six defined subgenera, namely Argas, Carios, Chiropterargas, Microargas, Persicargas, Secretargas and an undefined subgenus referring to Argas bureschi Dryenski 1957 (Hoogstraal, 1985). Particularly, the Argas (Persicargas) group is composed by 16 ornithophilous species phenotypically similar to each other (Hoogstraal, 1985;Estrada-Peña et al, 2003), and well adapted to parasitize domestic birds (Hoogstraal, 1956;Kohls et al, 1970), to which they can transmit pathogenic eubacteria (Burroughs, 1947;Zaher et al, 1977;Lisbôa et al, 2009) and viruses (Hoogstraal, 1985).…”

High similarity of morphological traits has historically overshadowed the identities and distributions of poultry-associated soft ticks Argas (Persicargas) miniatus and Argas (Persicargas) persicus in America. In order to model the occurrence of both parasites in the continent, in the current study we performed morphological and molecular analyses to identify ticks collected in hen houses from Brazil and northern Chile. Combining these results with literature data, and the examination of Argas allotments deposited in the tick collections "Coleção Nacional de Carrapatos Danilo Gonçalves Saraiva" (Brazil), the "Coleção Acarológica do Instituto Butantan São Paulo" (Brazil), and the "Colección Zoológica de la Academia de Ciencia de Cuba" (Cuba), we present a critical list with the localities where A. (P.) miniatus and A. (P.) persicus have been reported in the American continent. Our results confirmed the presence of A. (P.) miniatus in Brazil and Cuba, and A. (P.) persicus in Chile, which in particular, constitutes the first molecularly confirmed report of the later species for South America. Although A. (P.) miniatus and A. (P.) persicus have been documented in 21 American countries, the identity of some reports must still be considered as uncertain until detailed morphological and/or molecular studies are performed. When contrasted to a Köppen-Geiger climate classification, A. (P.) miniatus predominantly occurs in equatorial and A. (P.) persicus in arid climates. However, until undetermined reports of both species are correctly identified, any conclusion on their geo-climatological occurrence throughout the American continent would be rather speculative.

“…A. persicus is the main vector of two organisms causing severe or fatal diseases in fowls: Borrelia anserina (Zaher et al 1977) and Aegyptianella pullorum (Gothe and Kreier 1977). A. persicus has been reported to cause fowl paralysis (Gothe and Englert 1978) and has been suggested to play a role in transmitting Mycobacterium avium (fowl tuberculosis) (Blagodarnyy et al 1971).…”

This scanning electron microscopy study revealed that the egg of Argas persicus was covered with chorion which appeared as a wrinkled layer containing regions of three textures. The first had elevated parts of slightly rough surface. The second had irregular smooth elevations; each carried numerous parallel horizontal foldings with vertical ridges. The last region had rough surface with irregularly shaped projections. Following the removal of the chorion, shell was observed to have one polar micropyle and numerous slit like openings. Length (L), width (W) and L/W ratio of the egg were measured. Investigation of larvae revealed extensively folded integument of idiosoma and spherical or elongated tubercles on dorsal plate. Mouth enclosed between ventral hypostome and two dorsal chelicerae. Hypostome carried four longitudinal rows of conical denticles. Each chelicera was made up of two segments; the basal one appeared as a pocket for the distal one. Haller's organ consisted of an anterior pit containing seven sensilla and a posterior capsule with four apertures. Distribution of chemo- and mechano-sensilla on the body was examined. Measurements of whole body, idiosoma, dorsal plate, capitulum, hypostome, palp and different types of sensilla both on the body and Haller's organ are also presented.
