Acaricidal Efficacy of Thirty-Five Egyptian Plants Against the Camel Tick, Hyalomma Dromedarii.

Purpose: Alternative and affordable tick control strategies are crucial to control and prevent tick bites and tick-borne diseases.

Methods: In this study, we evaluated the acaricidal efficacy of 35 aqueous plant extracts (17%) against the camel tick, Hyalomma dromedarii.

Results: The phytochemical profile indicated the presence of various secondary substances.

First report of metacercariae and resulting histopathological changes in from Lake Nasser, Egypt.

Parasitological studies of 100 fish were collected from Lake Nasser, Aswan, Egypt. Out of them 75 were infected with metacercariae in two forms; encysted in most visceral organs and free only in air bladder. These were identified morphologically as minimum metacercariae (Strigeidida: Diplostomidae).

Anthelmintic activity of ginger, curcumin, and praziquentel against Raillietina cesticillus (in vitro and in vivo).

This work evaluates the anthelminitic activity of ginger and curcumin on the cestode Raillietina cesticillus. Live parasites were collected from intestine of naturally infected chickens in PBS 0.9 % and then incubated at 37 °C in media containing ginger extract at three different concentrations (125, 250, and 500 mg); every concentration was dissolved in 10 ml media.

In vitro and in vivo screening of anthelmintic activity of ginger and curcumin on Ascaridia galli.

Intestinal helmintic infection, continue to be a cause of major concern in several parts of the world, particularly in the developing nations. The use of plant extracts to control poultry helminths is increasing in different rearing systems. The anthelmintic activity of ginger and curcumin was studied on the nematode Ascaridia galli.

Molecular identification and phylogenetic analysis of Heterakis gallinae from native chickens in Egypt.

The genomic DNA was extracted from nematode parasites, Heterakis gallinae from specific host, native chickens. The polymerase chain reaction (PCR) was applied to make amplification of the DNA content that aids in the further studies. The primer was used in the PCR reactions that have the following sequences: forward (5'-GTTTCCGTAGGTGAACCTGC-3') and reverse (5'-ATATGCTTAAGTTCAGCGGGT-3').

Molecular characterization of Ascaridia galli infecting native chickens in Egypt.

Family: Ascaridae as a whole is distributed among Africa and adjacent regions and in many areas of the world. The nematode Ascaridia galli is one of the most pathogenic and economically important parasites of poultry. The adult affect the small intestine of the hosts feeding on digested food materials.
