The incidence of pertussis infection can be estimated in the population by defining a single high titre of anti pertussis toxin (PT) immunoglobulin G (IgG) antibody predictive of recent infection. Sera samples collected in 1986, 1996 or annually between 1987 and 1998 were tested for anti-PT IgG antibody. In 1996, the age-adjusted prevalence of pertussis infection was 1.2% and was higher in chil...
Canine visceral leishmaniasis is a major public health problem that is endemic in tropical and sub tropical countries and is fatal in humans and dogs. In addition to symptomatic dogs, asymptomatic ones seem as source of Leishmania infantum infection. Thus surveillance and control programs of reservoir hosts are essential. This study aimed to evaluate the sero-prevalence of visceral leishmaniasi...

The purpose of this survey was to determine the prevalence of Leptospira infection in shorthair cats in different location of Mashhad, Iran. Totally, 147 blood samples were taken from 42 (28.57%), 52 (35.37%) and 53 (36.05%) households...
