Abstract
Trichinellosis is one of the most widespread zoonotic parasitic diseases of animals and man allover the world. This study aimed to determine the occurrence of Trichinella spiralis among pigs and humans in Assiut and Sohag Governorates in Upper Egypt. Trichinellosis was detected in 4.0% of the examined pigs with a prevalence rate of 5.0% and 2.0% in Assiut and Sohage Governorates, respectively. Male pigs were more susceptible (4.8%) than females (2.2%). There was a reverse relationship between the age of pigs and the occurrence of Trichinellosis. Diagnosis of Trichinella spiralis by digestion technique (4.0%) showed to be more sensitive than trichinoscope (3.33%) examination. Incidence of Trichinellosis in human was 60.8% with a rate of 67.7% % in Assiut Governorate and 46.7% in Sohage Governorate by using ELISA. There was a reverse relationship between the patient's age and the occurrence of Trichinellosis. Higher occurrence of Trichinellosis was detected in female patients (61.8%) than males (56.3%).
Highlights
Trichinellosis is one of the most widespread zoonotic parasitic diseases of animals and man allover the world in most climates except for deserts (Dupouy-Camet, 2000)
Pigs are the main reservoir of human trichinellosis and they acquire the infection through feeding on raw pork scraps from slaughterhouses and garbage
The cannibalistic behavior of pigs plays a role in transmission of trichinellosis (Pozio, 2001)
Summary
Trichinellosis is one of the most widespread zoonotic parasitic diseases of animals and man allover the world in most climates except for deserts (Dupouy-Camet, 2000). It is caused by a nematode parasite belonging to the genus Trichinella, which is an obligate intracellular parasite in both larval and immature adult stage (Capó and Despommier, 1996). Eight Trichinella species containing 11 genotypes have been identified and no morphological differences exist between the species and genotypes They have been differentiated from each other by molecular and biochemical methods (Pozio, 2005). Human acquires trichinellosis by ingesting raw or insufficiently cooked pork meat and other animals (horses and dogs) containing the larvae of Trichinella (Dupouy-Camet, 2000)
