Control of ctenocephalides felis on dogs and cats using the insect growth regulator [or chitin synthesis inhibitor] lufenuron program, in Egypt

Lufenuron, the chitin synthesis inhibitor [Program, Novartis, Switzerland] was given orally at doses of 10 mg/kg b. wt. to dogs and 30 mg/kg b. wt. to cats every four weeks [monthly] for the treatment of experimental flea infestations. Three-four weeks after the last infestation, lufenuron had effectively controlled the Ct. Felis infestation of dogs and cats as the drug prevented the development of the offspring of adult female fleas feeding on animals. Flea populations remained absent or very low until the end of the study, 91 days after the first treatment

Cryptosporidium nasorum among mugil cephalus and tilapia zillii from three different localities in Egypt

In order to add data on fish cryptosporidiosis in Egypt, the present work was conducted on 213 fish [Mugil cephalus and Tilapia zillii] collected from Mediterranean Sea [Port Said], Suez Canal [Ismailia] and Fayoum [Lake Quarun] during the period from June to November 1996. Cryptosporidium nasorum was recorded from 27.23% of them. Crosstransmission of this pathogen to chicken host failed. Furthermore, the present work confirmed the impossible transmission of C. parvum to the lower vertebrates [fish]

Application of a new formulation of ivermectin [ivomec pour-on] to control external papasiyes of farm animals in Egypt

Testing the efficacy of Ivomec pour-on [1 ml/10 kg b.wt.] against buffalo mites [Psoroptes natalensis], buffalo lice [Hematopinus eurysternus] showed 100%, 100% and 99.98% curicity rate, respectively. It is worthy to mention that this new formulation of Ivomec pour-on has a wide spectrum ectoparasiticidal effect on farm animals under the Egyptian environment

Scanning electron microscopy on the 3rd larval stage of cephalopina titillator fly diptera: Oestridae

Light as well as scanning electron microscopic studies on the 3rd larval stage of Cephalopina titillator fly were performed. The SEM studies of the different structures were done to enable the relation of the micromorphology of such structures with their functions. The mouth parts with the oral ridges and the minute spinules were adapted for semi-liquid nutrients. Each body segment was provided with eight bilobed fleshy processes and creeping welts which carry 3-4 rows of spinules. Posteriorly, the post-abdominal spiracles were consisted of several irregularly scattered zigzag tracheal gills

Epimastigote stage in the larvae of cephalopina titillator [Diptera: Oestridae] infesting camels [Camelus dromedarius] infected with trypanosoma evansi

The present study revealed that all the 3 larval stages of C. titillator collected from T. Evansi infected camels were heavily infected with epimastigote stage. This epimastigote stage was found always in a dividing stage. Experimental infection of mice and guinea pigs with this epimastigote revealed negative results. Further studies are needed to clarify the role of C. titillator in the epidemiology of T. evansi

Kaillietina aegyptiacus: a new species from Egyptian domestic pigeons

The present investigation revealed a rate of 19.49% among Egyptian pigeons infested with three Raillietina species, R. echinobothrida [Megnin, 1881]; Southwell and Lake [1939], R. georgiensis, Reid and Nugara [1961] and R. aegyptiacus n. sp. The third species was quite different from all previously known Raillietina species in the position of common genital pores, the heavily armed suckers, the double rows of the rosttellar hooks as well as other morphological differences. Such variation were enough for recording R. aegyptiacus as a new species
