Evidence of typhus infection in domestic animals in Egypt. 1966

I Z Imam, and L Alfy

Previous work suggested that domestic animals could act as a reservoir of epidemic typhus. To test this hypothesis, sera from buffaloes, camels, donkeys, goats, pigs and sheep in different parts of Egypt were submitted to the complement-fixation test, using the common soluble typhus antigen. The highest percentage of positive results was obtained with camel and donkey sera and the positivity rate was higher towards the end of the year than in June and July. Animals from the Western Desert area were more frequently positive than those from other regions. Attempts to isolate rickettsiae by intraperitoneal injection of guinea-pigs resulted in some febrile reactions, but so far no rickettsiae have been isolated.

UI	MeSH Term	Description	Entries
D003168	Complement Fixation Tests	Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.

D000829	Animals, Domestic	Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including LIVESTOCK (specifically CATTLE; SHEEP; HORSES; etc.), POULTRY; and those raised or kept for pleasure and companionship, e.g., PETS; or specifically DOGS; CATS; etc.	Farm Animals,Domestic Animals,Domesticated Animals,Animal, Domestic,Animal, Domesticated,Animal, Farm,Animals, Domesticated,Animals, Farm,Domestic Animal,Domesticated Animal,Farm Animal
D014438	Typhus, Epidemic Louse-Borne	The classic form of typhus, caused by RICKETTSIA PROWAZEKII, which is transmitted from man to man by the louse Pediculus humanus corporis. This disease is characterized by the sudden onset of intense headache, malaise, and generalized myalgia followed by the formation of a macular skin eruption and vascular and neurologic disturbances.
