Cryptosporidium parvum is an emerging waterborne zoonotic disease prevalent

C.parvum.It is intestinal protozoon belongs to coccidian family that causes damage to intestinal

specific it can equally infect humans, calves and foals. It is cross transmissible among mammals.
In horses, cryptosporidiosis is most commonly seen in foals (most frequently 1–4 weeks of age)

Compared to non-diarrheic foals. A significantly higher infection rate was observed in those
foals having contact with other animals like rodents, ruminants and dogs. Infection rate (15%)
was observed in those foals having contact with other animals and infection rate (6.5%) observed
in foals having no contact with other animals. Purpose seems to very important in this study.
Game horses have more infection rate which was (15.45%) as compared to draught horses
(4.4%). Game horses have three times more infection as compared to draught horses because
game horses remain in close confinement and foals have more prone to infection. Management is
an important factor infection rate was more in those stud farms having poor management as
compared to those have good management. Infection rate is poorly manage farms was (20.97%)
and (5.5%) in properly manage farms. The results of the comparative efficacy of nitazoxanide,
furazolidone and garlic showed that the Nitazoxanide was the most effective of the three in
treating cryptosporidium infection under field conditions. Efficacy of Nitazoxanide in treating
C.parvum in foals was (88%) during the study followed by furazolidone which have comparative
efficacy of (77%) than garlic with the efficacy of (70%).
In conclusion from above discussion reveals that C. parvum is prevalent in stud
farms in and around Lahore. Associated risk for C. parvum in foals are age less than 6 months,
immune-deficiency, contact with other animals like ruminants and poor management. Infection
rate is more in game horses as compared to draught horses because game horses are manage in
close confinement so the chances of infection are more. Treatment of C.parvum has long course
and effective drug for the treatment of cryptosporidiosis in foals is Nitaoxanide than
furazolidone.
