Abstract

The seasonal dynamic of ixodid ticks and infection rate with Borreiia Sp. in
ixodid ticks, human, domestic animals (camels, goats 8 sheep, dogs, cattle, and
buffaloes), and pet animals (dogs) were investigated in El- Tal El:- kebeer, Esmaieliya
governorate for 2 successive years from Mar. 2000 to Feb. 2002. The borrelial
infection rate occurred in the tick population throughout the year. Spirochetes were
detected in 3?.28% of the 1870 ticks examined. The highest percentage (p < 0.001),
of infection with Borreiia Sp. in ticks were recorded in H. dromedarii (47.92%), followed
by R. sanguineus (38.37%), B. annuiatus (32.5%), and H. excavatum (30.42%). The
prevalence of infection rate with Borreiia Sp. in the females of each species was
higher than males. The highest levels of infection with Borreiia in adult ticks were
recorded in summer. Boneiia spirochete was detected in 35.79% of the blood
samples (1900 samples) which were collected from man in Esmaieliya. governorate.
Where, the maximum infection rates were recorded in July. The highest infection rate
in blood smears which were collected from animals in Esmaieliya was recorded in
camels (23.45%), followed by dogs (13.27%), goats 8. sheep (12.15%), cattle and
buffaloes (10%). The changes in prevalence of Borrelia infection rate in the tick
population were positively correlated with changes in antibody prevalence in man and
animal hosts and with changes in the tick population density. Generally, the all studied
events were low in winter and early spring and gradually increased to reach the
highest levels in summer (maximum level in Aug.) and autumn.
