Development of Thelastoma bulhoesi (Oxyurata: Thelastomatida) and the Effect of Thiabendazole on the Unembryonated Egg.

Effect 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 ...

The Effect of Thelastoma bulhoesi and Hammerschmidtiella diesingi (Nematoda: Oxyurata) on Host Size and Physiology in Periplaneta americana (Arthropoda: Blattidae)

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. T...

Observations on the efficiency of thiabendazole, albendazole and brotianide against natural dicrocoeliasis in sheep and goats in Iran

Efficiency of the Injection of Trimethoprim/Sulfamethoxazole Solution on Game Bird Embryonated-Egg During the Late Stage of Development

Infectious agents cause disease in virtually any susceptible hosts. In the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antibiotics into hatching eggs. There is little information available describing the safety of the folate antimetabolite/sulfonamide class of antibiotics on the game birds embryonated eggs. The objective of this study was ...

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...
