  • Characterization Based on the 56-Kda Type-Specific Antigen Gene of Orientia tsutsugamushi Genotypes Isolated from Leptotrombidium Mites and the Rodent Host Post-Infection.

Characterization of the 56-kDa type-specific antigen (TSA) genes of Orientia tsutsugamushi (OT) from three naturally infected, laboratory-reared mite colonies comprising three species (Leptotrombidium deliense [Ld], Leptotrombidium imphalum [Li], and Leptotrombidium chiangraiensis [Lc]) has revealed the presence of single and coexisting OT genotypes found in individual chiggers. The Karp genotype was found in all of the chiggers examined, whereas Gilliam and UT302 genotypes were only observed in combination with the Karp genotype. From analysis of these OT genotypes after transmission from chiggers to mice it was determined that with the Lc and Li mites, the OT genotype composition in the rodent spleens post-infection had not changed and therefore resembled that observed in the feeding chiggers. However, only the Karp genotype was found in rodents after feeding by Ld chiggers carrying Karp and Gilliam genotypes. The current findings reveal a complex association among the host, pathogen, and vector.

  • A new genus and two new species of chigger mites (Acari: Trombiculidae) from the Laotian rock-rat Laonastes aenigmamus Jenkins, Kilpatrick, Robinson & Timmins (Rodentia: Diatomyidae).
  • Stekolnikov AA.Author information Zoological Institute, Universitetskaya Embankment 1, St. Petersburg, 199034, Russia, trombicula@mail.ru.AbstractA new chigger mite genus Laotrombicula n. g. and two new species, Laotrombicula khunboromi n. sp. (type-species) and L. fangumi n. sp., are described from the Laotian rock-rat Laonastes aenigmamus Jenkins, Kilpatrick, Robinson & Timmins (Rodentia: Diatomyidae). The new genus is most similar to Trombiculindus Radford, 1948 and Leptotrombidium Nagayo, Miyagawa, Mitamura & Imamura, 1916 and differs from these genera by having the scutum of subhexagonal or semicircular shape vs widely rectangular; pinnatifid dorsocentral idiosomal setae vs foliaceous in Trombiculindus and unexpanded in Leptotrombidium; and by the presence of serrated longitudinal crests in the middle part of scutum.

  • ECTOPARASITE BURDENS OF THE COMMON MOLE-RAT (CRYPTOMYS HOTTENTOTUS HOTTENTOTUS) FROM THE CAPE PROVINCES OF SOUTH AFRICA.
  • Archer EK, Bennett NC, Ueckermann EA, Lutermann H.Author information University of Pretoria, Mammal Research Institure, Department of Zoology & Entomology, University of Pretoria.AbstractAbstract The members of the African mole-rat family (Bathyergidae) are widely distributed across sub-Saharan Africa. Despite their well-studied biology and reproductive physiology the current knowledge of their ectoparasite fauna is limited and ambiguous due to recent revisions of the bathyergid taxonomy. The common mole-rat (Cryptomys hottentotus hottentotus) is 1 of the most widely distributed species of these subterranean rodents. Ectoparasites were collected from 268 common mole-rats at 2 localities (Western and Northern Cape Province) in South Africa over the course of 18 mo with the aim to document species richness, prevalence and abundance of these ectoparasites. The aggregation of parasite species, sex bias within a species and seasonal variation in ectoparasite burdens were investigated. A total of 4830 individual parasites from 4 mite species (Androlaelaps scapularis, A. capensis, Radfordia ensifera and 1 undetermined chigger (Family Trombiculidae), 1 flea species (Cryptopsylla ingrami) and 1 louse species (Eulinognathus hilli) were collected. With the exception of R. ensifera and the chigger all of these ectoparasites appear to be host specific either for the host species or the Bathyergidae. Aggregation indices indicated that with the exception of E. hilli the distribution of all parasite species was highly aggregated among hosts and sex biased. Seasonal variation in prevalence, abundance and species richness was apparent with greater burdens in the rainy winter season. This is likely related to seasonal variation in abiotic factors but may also be affected by the timing of host reproduction and dispersal behavior.
