SEROPREVALENCE OF TOXOPLASMA GONDII AMONG COMMENSAL RODENTS FROM GIZA GOVERNORATE, EGYPT.

Toxoplasma gondii is an obligate intracellular zoonotic parasite that infects a large spectrum of warm-blood animals, including humans. Congenital toxoplasmosis is a worldwide problem. Rodents are intermediate hosts and serve as food for felids, the definitive hosts.

RESPONSE OF DOMINANT RODENTS TO COUMATETRALYL AND BROMADIOLONE IN GREATER CAIRO, EGYPT.

Since the 1950s, anticoagulant rodenticides are used to control rodents in public health and agriculture sectors. The extensive use of these compounds has acted as selective force to rodents, leading to resistance. Resistance mechanisms have been iden- tified in rats and mice, including the modification of the enzyme that activates vitamin K, vitamin K epoxide reductase (VKOR).

EFFICACY OF THREE INSECTICIDES ON RAT FLEA (XENOPSYLLA CHEOPIS) INFESTING RODENTS IN GIZA GOVERNORATE, EGYPT.

The extensive use of insecticides in public health and agriculture sectors is the main reason for development of resistance in fleas associated in domestic rodents. The present work was planned to investigate the insecticidal efficacy of Lambda-cyhalothrin, Chlorpyrifos and Fenitrothion against rat flea (Xenopsylla cheopis) infesting rodent species in Giza Governorate, Egypt. The lethal concentration Lc₅₀ and Lc₉₀ of population percent were obtained from the established regression log concentrate-response lines.

Efficacy of certain insecticides against rat flea (Xenopsylla cheopis) among rodent species in Cairo Governorate, Egypt.

The efficacy of malathion, chlorpyrifos and deltamethrine to oriental rat flea, Xenopsylla cheopis associated different rodent species was carried out in Cairo Governorates. The results indicated that the LC50 values were 1.972, 1.

Field studies on dominant rodents and the efficacy of certain insecticides to their fleas in Dakahlia Governorate, Egypt.

A preliminary survey of domestic rodent and the efficacy of bendiocarb, diazinon and pirimiphos-methyl insecticides to their fleas were carried out in Dakahlia Governorates (Aga, Meet-Ghamr, El-Senbellawen, Temi El-Amded, Beni-Abed, Dekernes, Nabarow, Talkha, Menia El-Nasr and El-Kordy). Rodent index (number of rodent/trap) and percentage frequency of drodent species were recorded from October 2010 to May 2011. The main rodent species found were the Norway rat, Rattus norvegicus, the grey-bellied rat, R.
