Rift Valley Fever in Egypt and other African countries: Historical review, recent outbreaks and possibility of disease occurrence in Egypt.

This article reviews and discusses the historical and recent status of Rift Valley Fever (RVF) in Egypt and the other African countries based on the available and scattered reports. The recent outbreaks in African countries were reviewed and mapped out. Four major epidemics have been recorded in Egypt (1977, 1978, 1993 and 2003).

Insects associated with hospital environment in Egypt with special reference to the medically important species.

A study was planned to examine the insect fauna associated with two hospitals: urban (A) in Cairo and rural (B) in Banha, Egypt with varying hygienic levels and their adjacent residential areas (AC) and (BC), respectively and to investigate the effect of hygienic level on species composition and relative abundance. A total of 22 species belonging to 7 orders and 15 families were reported in the four study areas of which, Dipterous flies were the most common (8/22, 36.36% species).

Population ecology of mosquitoes and the status of bancroftian filariasis in El Dakahlia Governorate, the Nile delta, Egypt.

Mosquitoes were surveyed (Oct. 2010 & Apr. - Oct.

Life table characteristics of the female sandfly, Phlebotomus papatasi (Scopoli) (Diptera: Psychodidae) under three food regimes.

Background & Objectives: In Egypt, Phlebotomus papatasi is the main vector of cutaneous leishmaniasis. In nature, P. papatasi feeds on blood from different hosts and sucrose (other sugars) mainly from fig fruits.

Mosquitoes (Diptera: Culicidae) in relation to the risk of disease transmission in El Ismailia Governorate, Egypt.

Mosquito were surveyed (Nov. 2009 - March 2010) in El Ismailia Governorate. Nine species were reported: Culex pipiens, Cx.

Geographical distribution and relative abundance of culicine mosquitoes in relation to transmission of lymphatic filariasis in El Menoufia Governorate, Egypt.

Culicine mosquito were surveyed in El Menoufia Governorate (October to November 2008 and April to May 2009) in villages representing eight districts. Six species were reported: Culex (Culex) pipiens Linnaeus, Cx. (Cx) perexiguus Theobald, Cx.

Hematological changes in mice exposed to biting of the bedbug: Cimex lectularius L. (Hemiptera: Cimicidae).

The studies on hematologic changes in humans or animals as a result of bedbug bites are lacking. This study was undertaken to examine changes in the blood picture of mice (Mus musculus) exposed to Cimex lectularius biting. As compared to the check animals, mice exposed to bedbug bites either once or twice within 7 days showed insignificantly higher WBC's (1.

Susceptibility of bromadiolone anticoagulant rodenticide in two rodent species and its haematologic effect.

Susceptibility levels of the Norway rat, Rattus norvegicus and the roof rat, Rattus rattus to bromadiolone anticoagulant rodenticide by bioassay and biochemical methods were studied. Animals were trapped from Giza and Qualyobia Governorates in which the anticoagulant rodenticides were used to control rodents for long periods. Complete mortality was obtained for both species and sexes within standard no-choice feeding test period (4 days) indicating bromadiolone susceptibility.

Effect of warfarin anticoagulant rodenticide on the blood cell counts of Rattus norvegicus and Rattus rattus.

The effect of the warfarin LD50 on the counts of the blood cells of Norway rat, Rattus norvegicus and roof rat, Rattus rattus from Giza and Qualyobia Governorates was investigated in the laboratory. Warfarin toxication caused significantly different blood cell counts in treated rats compared to control ones. Warfarin significantly decreased the total erythrocytic count and increased the total leucocytic count of treated rats.

Detection of haematologic effects of mosquito biting using an animal model.

The studies on haematologic changes in humans or animals as a result of mosquito bites are few. This study was undertaken to examines changes in the blood picture of mice (Mus musculus) exposed to Culex pipiens biting. Mice exposed to mosquito bites either once or twice (with 7 days between the two bites) showed insignificantly higher (P >0.

Immunomodulatory properties of sand fly saliva and its role on vertebrate host.

The salivary glands of Phlebotomus papatasi and P. langeroni were investigated for their immunomodulatory properties on vertebrate hosts. Laboratory reared sand fly, were used for feeding on hamsters and for extraction of salivary gland.
