“…S. Khokhlova and others McTier et al (1981) showed that in guinea pigs, cross-immunity occurred between two ticks of Dermacentor genus but not between ticks belonging to Dermacentor and Amblyomma genera. Rabbits demonstrated cross-resistance between two ticks of Hyalomma genus (Kumar and Kumar, 1996), but not between Rhipicephalus and Ixodes genera (Rechav et al, 1989). Furthermore, cross-immunity between two Rhipicephalus species was reported for rabbits (Njau and Nyindo, 1987), whereas no cross-immunity between these two ticks was found in guinea pigs (Rechav et al, 1989).…”

SUMMARY We studied immune responses of the jird Meriones crassus to different flea species belonging to the same family. We used jirds maintained in an outdoor enclosure (enclosure; N=18) and parasitized by fleas Xenopsylla conformis mycerini and Xenopsylla ramesis, and also jirds born in the laboratory to previously parasitized mothers(laboratory animals; N=23). We asked (i) whether cross-immunity to different fleas occurs, (ii) whether there is a sex difference in immune responses to flea parasitism and (iii) whether the severity of the immune responses depends on parasite load. In the enclosure animals, immune response to antigen from the unfamiliar flea Synosternus cleopatrae pyramidisdid not differ from those to antigens from the familiar fleas. In contrast,laboratory rodents demonstrated no difference in the immune response between S. c. pyramidis antigen and either the phytohemagglutinin treatment or controls, although their responses to antigens of fleas familiar to their mothers (X. c. mycerini and X. ramesis) were significantly higher than those to antigen of S. c. pyramidis and phytohemagglutinin. The results clearly demonstrated that (i) cross-reactivity in rodent responses to different flea species occurred for enclosure but not for laboratory jirds and (ii) immune-naïve animals whose mothers were parasitized by fleas had some degree of immunity against fleas. The only sex difference in immunological parameters was the higher level of circulating immune complexes in females than in males. Only phagocytic activity was affected by flea burden, decreasing with an increase in flea numbers.

“…During repeated infestation with other tick species, lowered efficiency of some physiological processes, first of all of feeding, maturation and oviposition processes [34,[37][38][39][40][41], embryonic development, as well as larval hatching and molting of the subsequent developmental stages [42][43][44] were observed. Moreover, lethality of the active tick stages was increased (unpublished data).…”

It was proved that transmission of some pathogens may occur between infected and uninfected ticks co-feeding on a host in the absence of systemic infection. The effect was studied of co-feeding of two different tick species Ixodes ricinus and Dermacentor reticulatus on the course of the non-parasitic stage. Species chosen for the experiment may share their habitats and co-infest animals in nature. In the course of the study the process of egg maturation, oviposition and larval hatching were investigated. In order to estimate if co-feeding influence can counteract host immunity, three subsequent infestations of rabbits were analyzed. Mono-specific groups values of such a parameters as egg amount, number of eggs per 1 mg of female engorgement weight, female oviposition weight loss, hatching success were higher in inter-specific groups were compared. The results indicate that co-feeding with other tick species may partially reduce the influence of host resistance in subsequent infestation.

Does acquired resistance of rodent hosts affect metabolic rate of fleas?

We studied whether (a) previous infestation of a rodent host with fleas and (b) the reproductive effort of fleas affect the rate of CO(2) emission in two flea species, host-specific Parapulex chephrenis and host-opportunistic Xenopsylla ramesis when feeding on their typical and atypical rodent hosts. We measured the rate of CO(2) emission in preovipositing and ovipositing female fleas fed on either pristine or previously infested Acomys cahirinus (typical host of P. chephrenis) and Dipodillus dasyurus (typical host of X. ramesis). When P. chephrenis fed on a typical host, its mass-specific rate of CO(2) emission was not affected by previous infestation of a host, whereas when this flea fed on the atypical host, its rate of CO(2) emission was higher when a host was previously infested. This was manifested, however, mainly during the oviposition period. The rate of CO(2) emission by X. ramesis feeding on pristine hosts was significantly lower than in conspecifics feeding on previously infested hosts, independent of host species. Both flea species feeding on their typical hosts emitted CO(2) at similar mass-specific rates during preoviposition and oviposition, except for P. chephrenis feeding on D. dasyurus, which increased its rate during oviposition. There was no effect of the number of eggs produced per female on the rate of CO(2) emission during oviposition.
