Abstract
Intestinal parasites have become one of the most important health problems for public health experts and decision-makers in many countries. In Zella city, the prevalence of intestinal parasites was not studied before, therefore, the current study was conducted to identify the intestinal parasites in Zella city. The data in this study was collected from the records of the central laboratory in Zella city over the period of time, from the beginning of 2015, till the end of 2019. A 839 samples were examined, and 728 samples were infected with parasites, which represent 87%. The results of the study revealed the presence of four types of intestinal parasites with different proportions as follows: Entamoeba histolytica by 65%, Ascaris lumbricoides by 24%, and Entamoeba coli by 10%, and Giardia lamblia by 0.7%. The results of the study also indicate that the infection rate of males and females were very close, 86% and 87%, respectively. The results of the current study also indicate that the single type infection pattern was the most common compared to the mixed parasite infection, 95%, and 5%, respectively. The study also shows that the percentage of intestinal parasites infection was higher during the autumn and spring seasons. Despite the increase in cultural and social awareness and the improvement of the living conditions of many families, the rate of intestinal parasites infection is still high, which requires more investigations.
Highlights
Intestinal parasites are one of the most important pathogens spread globally, especially in tropical and subtropical regions, as the number of infected people with Protozoa or Helminthes is estimated annually about 3.5 billion people, most of them children [1]
The results of the current study indicated that the percentage of infection varied in the study period
While the number of people infected with E. coli reached 71 patient, and the percentage of infection did not exceed 10%, and the results showed that the highest infection rate was in 2015 (14%), while the lowest infection rate was in 2016 (06%)
Summary
Intestinal parasites are one of the most important pathogens spread globally, especially in tropical and subtropical regions, as the number of infected people with Protozoa or Helminthes is estimated annually about 3.5 billion people, most of them children [1]. The diarrhea is one of the main causes of death in children, especially in some countries that lack the necessary conditions for personal hygiene and health care [2] Environmental, social, cultural conditions, and the level of family income in different societies are among the most important factors associated with the spread of intestinal parasites infection. Due to the overlap of clinical symptoms of parasite infection with the clinical symptoms of other causes of diarrhea such as bacteria and viruses, the mechanism of pathogen induced by intestinal parasites infection has not been sufficiently studied. Most of the diarrhea cases in developing countries, is related to intestinal parasites, in particular with in communities in rural areas, where poor health conditions, and the use of untreated sewage water in irrigation operations, [4]
