Abstract:
Blastocystis sp. is a common enteric parasite of humans and animals associated with inadequate sanitation and poor personal hygiene. Over the years, the Malaysian thriving economy has been facilitated largely by migrant workers from developing countries, and there is concern that diseases endemic to their countries may be imported. Therefore, this study aimed to determine the current status of Blastocystis infection as well as subtypes (STs) from fecal samples among migrant workers in Selangor and Kuala Lumpur, Malaysia. Overall, almost a third of the study cohort (30.9%; n = 68/220) screened were infected with Blastocystis sp. predominantly with ST3 (54.5%; n = 12), followed by ST1 (36.4%; n = 8) and ST2 (9.1%; n = 2). Infection levels was almost similar among the different sectors; manufacturing (32.8%), domestic service (32.3%), and food service (27.3%) with common symptoms for infection included stomach and abdominal pain or discomfort and diarrhea (48.5%; n = 33). None of the socio-demographic risk factors evaluated were significant. Therefore, this study warrants continuous monitoring as well as understanding the impact of transmission among the migrant community with the local population especially those involved in food service sector.
Insights
A study found nearly a third of migrant workers in Malaysia are infected with Blastocystis, a common enteric parasite. Subtype 3 was most prevalent, highlighting the need for ongoing monitoring and understanding transmission dynamics.
Area of Science:
- Medical Parasitology
- Public Health
- Infectious Diseases
Background:
- Blastocystis sp. is a prevalent enteric parasite linked to sanitation and hygiene.
- Migrant workers in Malaysia may introduce endemic diseases.
- Understanding Blastocystis transmission is crucial for public health.
Purpose of the Study:
- To determine the prevalence and subtypes of Blastocystis infection in migrant workers.
- To investigate potential risk factors and symptoms associated with Blastocystis infection.
- To inform public health strategies regarding parasitic infections in migrant populations.
Main Methods:
- Fecal samples were collected from migrant workers in Selangor and Kuala Lumpur.
- Blastocystis sp. infection and subtypes were identified using molecular methods.
- Socio-demographic data and clinical symptoms were recorded and analyzed.
Main Results:
- Overall prevalence of Blastocystis infection was 30.9% (68/220).
- Predominant subtypes were ST3 (54.5%), ST1 (36.4%), and ST2 (9.1%).
- Infection rates were similar across manufacturing, domestic service, and food service sectors; common symptoms included abdominal pain and diarrhea.
Conclusions:
- Blastocystis infection is common among migrant workers in Malaysia, with ST3 being the most frequent subtype.
- Continuous monitoring and research into transmission dynamics within the migrant community and with the local population, particularly in the food service sector, are warranted.
