Background Cryptosporidiosis is a disease caused by infection with an intestinal coccidian parasite Cryptosporidium. Cryptosporidium species are the second leading cause of diarrheal disease and death in children in developing countries. Until now, no data have been available or published on its prevalence among children with diarrhea in Sudan. Therefore, this paper was designed to determine the prevalence rate of Cryptosporidium among children with diarrhea under 5 years who were admitted to Kosti Teaching Hospital. Methods A hospital-based cross-sectional study including children under 5 years old admitted to the pediatric section of the hospital between September 2020 and December 2020. A total of one-hundred and fifty stool samples were collected. All stool samples were examined using the modified Ziehl Neelsen (mZN) staining technique and then examined microscopically for Cryptosporidium infection. Results A total of 150 children were examined out of which 70 presented with diarrhea. A greater prevalence of 19/70 (27.1%) of Cryptosporidium was observed in children with diarrhea than children without diarrhea 7/80 (8.8%). There was a significant relationship between the prevalence of Cryptosporidium and the presence of diarrhea in children under 5 years in the Kosti Teaching Hospital(P < 0.05). It was found that a higher prevalence was registered among children using piped-water sources for drinking. Conclusions The overall prevalence of parasite detected was 17.3% among children admitted to Kosti Teaching Hospital. The prevalence rate of the infection among Children with diarrhoea was 27.1%. Studying the prevalence rate of cryptosporidiosis among diarrheic children may predict their health status, leading to a better diagnosis, treatment, and, therefore, patients’ status improvement.

Background: Cryptosporidiosis is a disease caused by infection with an intestinal coccidian parasite Cryptosporidium. Cryptosporidium species are the second leading cause of diarrheal disease and death in children in developing countries. Until now, no data have been available or published on its prevalence rate among children with diarrhoea in Sudan. This paper was therefore, designed to determine the prevalence rate of Cryptosporidium among diarrhoeic children under 5 years admitted to Kosti Teaching Hospital. Methods: A hospital-based cross-sectional study including children with ages under 5 years old admitted to the paediatric section of the hospital between September 2020 and December 2020. A total of one-hundred and fifty stool samples were collected. All stool samples were examined using the modified Ziehl Neelsen (ZN) staining technique, and examined microscopically for Cryptosporidium infection. Results: A total of 150 children were examined out of which 70 presented with diarrhoea. A greater prevalence of 19/70 (27.1%) of Cryptosporidium was observed in children with diarrhoea than children without diarrhoea 7/80 (8.8%). There was a significant relationship between the prevalence of Cryptosporidium and the presence of diarrhoea in children under 5 years in Kosti Teaching Hospital(P<0.05). It was found that a higher prevalence was registered among children using pipe water for drinking.Conclusions: The overall prevalence of parasite detected was 17.3% among children admitted to Kosti Teaching Hospital. The prevalence rate of the infection among Children with diarrhoea was 27.1%. Studying the prevalence rate of cryptosporidiosis among diarrheic children may predict their health status, leading to a better diagnosis, treatment, and therefore, patients' status improvement.

Background: Malaria infection remains the most serious and widespread protozoan infection of humans and has been associated with different changes in hematological parameters. This study aimed to detect the effects of malaria infection on hematological parameters in Sudanese patients. Methods: This was a case–control study including 100 patients and 50 controls required from Kosti Teaching Hospital (Kosti City) from October 2, to November 11, 2020. All patients and controls were investigated for blood film for malaria, complete blood counts, and peripheral blood picture. The data were analyzed using SPSS version 16. Results: Hemoglobin (Hb) was decreased in 75% of our patients and in 10% of controls, P < 0.000. Hematocrit (HCT) was decreased in 55% of patients and in 8% of controls, P < 0.000. MCH was decreased in 33% of patients and in 12% of controls, P = 0.013. The mean corpuscular hemoglobin concentration (MCHC) was decreased in 30% of study patients and in 10% of controls, P = 0.002. The mean corpuscular volume was decreased in 34% of patients and in 8% of controls, P = 0.056. Platelet (PLTs) count was decreased in 46% of patients and 0% of controls, P < 0.000. Platelet crit (PCT) was decreased in 75% of patients and in 16% of controls, P < 0.000. Furthermore, there were differences in white blood cell (WBC) counts between malaria parasite patients and controls, P = 0.058. No significant difference in red blood cell counts was seen between malaria parasite patients and controls, P = 0.797. Conclusions: Malaria parasite infection linked to many changes in hematological parameter characterized by reduction in WBC counts, PLT counts, PCT, Hb level, HCT, MCH, and MCHC.
