ABSTRACT

 

Rasheed Alharby HY, Salih Alalusi TA, Prevalence of Cryptosporidium parvum, hematology and immune markers in hospitalized children and pathogenicity in Swiss mice, Onl J Vet Res., 23 (1):66-74, 2019. Cryptosporidium parvum, was isolated from feces of male and female children <10 years age. To assess pathology, the C parvum oocytes were gavaged in groups of Swiss mice. Of 300 feces of children tested, we detected C parvum in ~7%-13% feces by various methods with highest incidence by ELISA (40 children). We found higher prevalence in males (15.6%) than females (10.7%), aged 0-1y, ~29% and 6 to 9y 3.9%, from rural areas ~15% and cities ~9%. Compared with non-infected controls, red blood cells were ~ 2% lower, white cells 21% and platelets 17% higher, cholesterol 15%, triglyceride 21% and low and very low density lipoprotein 23-29% higher and protein 6%, albumin 12% and globulin 4% lower. In infected children values for complement 4 were +36% higher, C3 27%, IgA 43% and interleukin L2, 33% higher. Significance for differences between infected and non-infected data ranged P < 0.05 to <0.0001. In mice gavaged C parvum, we confirmed pathogenicity by observing infiltration by neutrophils, vacoulation, hemorrhage, and autolysis of structures with various stage of C parvum inside intestinal tissues. Our results suggest that in young children, C parvum mainly affected blood antibody immune markers and lipids.
