The Effect of Thelastoma bulhoesi and Hammerschmidtiella diesingi (Nematoda: Oxyurata) on Host Size and Physiology in Periplaneta americana (Arthropoda: Blattidae)
نویسنده
چکیده
Three thousand Periplaneta americana were sacrificed and the following data collected: number parasitized by oxyurid nematodes, age, sex, weight, length, specific gravity of hemolymph, differential cell counts of hemocytes, and the number of each nematode species present. The mean number of nematodes per host for adults and nymphs, and males and females were compared using the Student's Mest. The mean number of nematodes is significantly greater in adults and females. Therefore parasitized hosts are generally longer and heavier. The presence of oxyurid parasites did not appear to affect differential hemocyte counts or hemolymph specific gravity.

Use of random amplified polymorphic DNA (RAPD) for generating specific DNA probes for oxyuroid species (Nematoda).
Random amplified DNA markers (RAPD; Williams et al., 1990) were used to obtained specific RAPD fragments characterising different species of oxyuroids. We tested six species of worms parasitizing vertebrates or invertebrates: Passalurus ambiguus Rudolphi, 1819, parasite of Leporids; Syphacia obvelata (Rudolphi, 1802) Seurat, 1916, a parasite of rodents; Blatticola blattae (Graeffe, 1860) Chitwo...
متن کاملComposition of the Cockroach Gut Microbiome in the Presence of Parasitic Nematodes
Cockroaches are parasitized by thelastomatid nematodes, which live in an obligate manner in their hindgut and interact with the resident microbial community. In the present study, a composition analysis was performed on the gut microbiome of Periplaneta fuliginosa and P. americana to investigate natural and artificial infection by thelastomatid nematodes. Nine libraries of the 16S rRNA gene V3-...
متن کاملDevelopment of Thelastoma bulhoesi (Oxyurata: Thelastomatida) and the Effect of Thiabendazole on the Unembryonated Egg.
The embryological and postembryological development of Thelastoma bulhoesi was determined. Initial cleavage was into unequal cells and occurred within 1-2 hours at 25 C. Cell division was holoblastic but no true morula is formed. Gastrulation occurred at approximately 48 hours by epibolic synectic mechanisms. First-stage larvae were fully developed at 96 hours. The molt to second-stage larvae w...

Protozoan and nematode infections of Periplaneta americana in Bulgaria were investigated. Five protozoan and 2 nematode parasites of P. americana were recorded: Endamoeba blattae, Amoeba sp., Lophomonas striata, Nyctotherus ovalis, Balantidium blattarum, Hammerschmidtiella diesingi and Leidynema appendiculatum. Parasite prevalence varied from 1,6% for Amoeba sp. to 32,8% for nematodes. Biometri...
متن کاملEffect of Temperature on the Development of Thelastoma bulhoesi (Oxyurata, Thelastomatida) and Other Nematodes.
Embryonation of Thelastoma bulhoesi was monitored at eight temperatures between 0 and 35 C. Cell division did not occur below 15 C or at 35 C. Development was most rapid at 25 and 36 C. The effect of temperature on the rate of embryological development of T. bulhoesi at different stages was measured using the temperature coefficient, Q. The developmental temperature response curve obtained for ...
