Abstract:
Objective To investigate the status of Cryptosporidium infection in the population in the local area of Anhui Prov?ince,and discuss the risk factors of the infection,so as to provide the evidence for the prevention and treatment of cryptosporidi?osis. Methods Qianshan County and Lingbi County of Anhui Province were selected as investigation spots,and the oocysts of Cryptosporidium in the feces of the investigation objects and the specific IgG antibody against Cryptosporidium in the serum were checked by using the pathogenic modified acid fast staining method and ELISA,respectively,so as to determine the status of Cryptosporidium infection in these investigation objects. At the same time,the questionnaire surveys were conducted in the inves?tigation objects so as to know about the risk factors of Cryptosporidium infection. Results A total of 668 people were investigat?ed in the two counties,635 people received etiological examinations,and 15 people were positive with the positive rate of 2.36%;642 people received serological examinations,and 140 people were positive with the positive rate of 21.81%;628 peo?ple received pathogenic and serological examinations at the same time,and the examination results of the both methods showed that 12 people were positive(there were 4 people in Qianshan County and 8 people in Lingbi County),and the positive rate was 1.94%. The rates of Cryptosporidium infection in the population of Qianshan County and Lingbi County were 1.24%(4/322)and 2.71%(8/295)respectively,and the difference had no statistical significance(P>0.05). The single factor analysis found that the rate of Cryptosporidium infection was higher in the children and diarrhea patients;the multivariate logistics regression analy?sis indicated that the rate of Cryptosporidium infection was higher in the people who bred poultry and the diarrhea patients. Con?clusions The positive rate of serum antibody of Cryptosporidium in the population of the local area of Anhui Province is higher, which indicates that the previous infection is serious,and the rate of Cryptosporidium infection in human is relative to the age, diarrhea and whether there are poultries to be bred in the family,which is worthy of attention in the future prevention and treat?ment.
