    Surveys were conducted in the southern Malay peninsula to assess intestinal parasitism in the aboriginal ethnic minority groups. Faecal specimens from 1 273 persons were examined by the thiomersal-iodine-formol direct-smear technique. Prevalences are reported and, for helminth infections, data on worm burdens. The state of sanitation in each of 9 cultural-ecological groups was assessed by means of a simplified system of scoring for variables. Particular attention was paid to relationships between cultural and ecological factors, sanitation, and observed patterns of intestinal parasitism. The author also discusses the fact that the number of parasitic species diminishes in habitats simplified by man, whereas an increase occurs in the prevalence and intensity of the more adaptable species that persist in ecosystems of low complexity.

    BACKGROUND: Intestinal parasitic infections (IPIs) are still major health problems in many developing countries including Malaysia, particularly in the poor and socioeconomically deprived rural and remote communities in Peninsular Malaysia. This study was conducted to determine the prevalence of IPIs and to identify the key factors associated with intestinal polyparasitism as well as to evaluate the knowledge, attitude and practices (KAP) on IPIs among rural Orang Asli and Malay communities in Terengganu, Malaysia.

    METHODS: A cross-sectional study was conducted among 340 participants (165 Orang Asli and 175 Malay) aged ≤ 15 years from the Hulu Terengganu and Kemaman districts of Terengganu. Faecal samples were examined for the presence of intestinal parasites by using direct smear, formalin-ether sedimentation, trichrome stain, modified Ziehl Neelsen stain, in vitro cultivation in Jones' medium, Kato Katz and Harada Mori techniques. Demographic, socioeconomic, environmental and behavioural information of the participants and their KAP for IPIs were collected by using a pre-tested questionnaire.

    RESULTS: Overall, 149 (90.3 %) Orang Asli and 43 (24.6 %) Malay children were infected by at least one parasite species. The overall prevalences of intestinal polyparasitism among the Orang Asli and Malay were 68.5 % (113/165) and 14.3 % (25/175), respectively. Multiple logistic regression analysis showed that using unsafe water supply as a source for drinking water, the presence of domestic animals, not wearing shoes when outside, not washing vegetables before consumption, not washing hands after playing with soil, indiscriminate defecation and the low level of mother's education were the key risk factors for intestinal polyparasitism among the Orang Asli, while working mothers and the presence of domestic animals were the risk factors among the Malay children. Almost all the Malays were well aware about the IPIs while Orang Asli respondents had a poor level of related awareness.

    CONCLUSIONS: This study demonstrates that IPIs are highly prevalent in rural Terengganu, Malaysia. Community awareness about IPIs was found to be imperative in protecting Malay children from these infections. An integrated control programme for the prevention and control of IPIs is highly recommended for these communities, with a special emphasis on the Orang Asli population.

  6. Parasitic infections among Southeast Asian labourers in Taiwan: a long-term study
    Wang LC
    Epidemiol Infect, 1998 Feb;120(1):81-6.
    PMID: 9528821
    Parasitic infections have been reported to be relatively common among the Southeast Asian labourers in Taiwan. This study, conducted in 1992-6, was designed to determine the temporal changes of the prevalence. Faecal specimens were examined by the formalin-ethyl acetate sedimentation technique and blood samples screened using the quantitative buffy coat technique and confirmed by Giemsa stained blood smear. The overall prevalence of intestinal parasitic infections was 10.3%. The annual prevalence decreased from 33.3% in 1992-3 to 4.6% in 1995-6. The Thai (12.0%) and Indonesian (11.1%) had a higher prevalence than the Malaysian (6.7%) and Filipinos (5.9%). Opisthorchis viverrini was the most important parasite in the Thai and Trichuris trichiura in the remaining groups. Moreover, no blood parasites were found in the labourers. The dramatic temporal decline in the intestinal parasitic infections suggests that limiting the entry of infected persons, periodic follow-ups, and immediate treatment of sporadic cases are necessary in preventing transmission of non-indigenous parasites through large population change.

    PMID: 15906644
    A total of 246 stool samples were collected from the public who participated in a Medical Fair held at the University Malaya Medical Center. The stools were examined for intestinal parasites using the formalin-ether concentration technique. The overall infection rate was 6.9% (17 out of 246), with Trichuris trichiura being the most common parasite (4.5%), followed by Ascaris lumbricoides (0.8%), Clonorchis sinensis (0.8%), hookworm (0.4%), and Entamoeba histolytica (0.4%). None of these participants showed any clinical symptoms. The highest infection rate was among the Chinese 7.7% (13 out of 169), followed by the Malays 7.0% (3 out of 43) and Indians 3.3% (1 out of 30). The highest infection rate was in the age group 16-30 years, which was 9% (6 out of 67). The two cases of clonorchiasis were from two Chinese women aged 28 and 66 years. The 28-year-old Chinese woman was born in Malaysia and had never left the country, while the older woman was also born in Malaysia but had visited Hong Kong as a tourist on two occasions. Both enjoyed eating raw fresh water fish with porridge.

    PMID: 7777914
    The infection rate and relationship of enterobiasis with socio-economic status were determined in children aged 1-8 years, living in a rural area in Malaysia. Of the 178 subjects 40.4% were infected with Enterobius vermicularis. The distribution of enterobiasis among these children were analyzed in relation to age groups and sex. The rate of infection was significantly higher in older children (5-7 years). The association of enterobiasis with other factors studied such as number of persons per house, household income per months and mother's employment status were not significant. The sensitivity of three successive days anal swabs compared to a single swab was found to be statistically significant.

    Southeast Asian J Trop Med Public Health, 1994 Sep;25(3):490-3.
    PMID: 7777913
    Blastocystis hominis has long been described as a non pathogenic protozoan parasite until recently when claims have been made that it can result in pathogenic conditions. Of the 729 stool samples (614 from survey and 115 from pediatric wards) examined, 18.1% of them were found to be positive for one or more intestinal protozoan cyst. The commonest was Giardia intestinalis (8.4%) Followed by Entamoeba coli (7.1%) and Entamoeba histolytica (5.1%) in the normal children without symptoms of diarrhea. When diarrheic stools were examined, the commonest parasite encountered was Giardia (20.4%), followed by E. coli (15.9%) and E. histolytica (9.7%). Blastocystis was observed in 4.4% of the children who had diarrhea and 1.1% among the children taken from the normal population in the rural areas.

  11. Fulltext Review of sarcocystosis in Malaysia
    Kan SP, Pathmanathan R
    Southeast Asian J Trop Med Public Health, 1991 Dec;22 Suppl:129-34.
    PMID: 1822870
    Sarcocystis is a tissue coccidian with an obligatory two-host life cycle. The sexual generations of gametogony and sporogony occur in the lamina propria of the small intestine of definitive hosts which shed infective sporocysts in their stools and present with intestinal sarcocystosis. Asexual multiplication occurs in the skeletal and cardiac muscles of intermediate hosts which harbor Sarcocystis cysts in their muscles and present with muscular sarcocystosis. In Malaysia, Sarcocystis cysts have been reported from many domestic and wild animals, including domestic and field rats, moonrats, bandicoots, slow loris, buffalo, and monkey, and man. The known definitive hosts for some species of Sarcocystis are the domestic cat, dog and the reticulated python. Human muscular sarcocystosis in Malaysia is a zoonotic infection acquired by contamination of food or drink with sporocysts shed by definitive hosts. The cysts reported in human muscle resembled those seen in the moonrat, Echinosorex gymnurus, and the long-tailed monkey, Macaca fascicularis. While human intestinal sarcocystosis has not been reported in Malaysia so far, it can be assumed that such cases may not be infrequent in view of the occurrence of Sarcocystis cysts in meat animals, such as buffalo. The overall seroprevalence of 19.8% reported among the main racial groups in Malaysia indicates that sarcocystosis (both the intestinal and muscular forms) may be emerging as a significant food-borne zoonotic infection in the country.

    Intestinal parasitic infections are important public health problems among underprivileged communities. This study was carried out to evaluate the infection rate of intestinal parasites among aborigine children at Pos Sungai Rual, Kelantan, Malaysia. A total of 111 faecal samples from aborigine children aged 4-12 years were screened for intestinal parasites by direct smear technique. Harada-Mori culture was also performed to identify hookworm and Strongyloides stercoralis larvae. The results showed that 87.4% of the children examined were positive for one or more parasites. Intestinal parasites were significantly lower in boys (78.7%) as compared to girls (93.8%). The infection occurred in very young children aged 4-6 years (80.0%) and the percentage of parasite-positive cases appeared to be significantly higher (92.9%) among the children aged 7-9 years. Trichuris trichiura was the most common parasite found in aborigine children (65.8%). Low socioeconomic status, poor environmental sanitation and poor personal hygiene are possible contributing factors that increase the rate of intestinal parasitic infections among the children. Thus, the parasitic diseases will continue to threaten the people's health especially among communities from rural areas if no appropriate actions are taken to diminish the transmission of the parasites.

  14. Seasonal variations in the numbers of trichostrongylid nematode eggs and their larvae in the faeces of farmed goats in Malaysia
    Rahman WA
    Vet Parasitol, 1992 Apr;42(1-2):163-6.
    PMID: 1615628
    Faecal worm egg counts of goats from two farms in Penang Island, West Malaysia, were monitored over a period of 14 months. The faecal egg count pattern followed that of total rainfall. The humid tropical environment was favourable for the development of various species of trichostrongylid nematodes, namely Haemonchus contortus, Trichostrongylus spp., Oesophagostomum spp. and Cooperia spp. Generally, H. contortus was observed to be the predominant species, more so in the monsoon months of the year.

    PMID: 1469913
    This paper describes the first Malaysian case of oesophagostomiasis. The patient was an 8-year-old Malay boy who presented to Ipoh General Hospital, Perak with abdominal pain and weight loss. Examination revealed multiple cavitated pseudotumours of the colon. A hemicolectomy was performed. Examination of the lesions revealed Oesophagostomum worms in the necrotic centres. The differential diagnoses and the pathology caused by Oesophagostomum are discussed. A brief review of the available literature is presented.

  16. Isospora corvi Ray, Shivnani, Oommen and Bhaskaran, 1952 from the common house crow (Corvus splendens Vieillot) of Selangor, peninsular Malaysia
    Poon SK, Chew WK

    PMID: 1808029
    Faecal samples of 56 common house crows (Corvus splendens Vieillot) were collected from the Petaling Jaya and Kelang districts of Selangor, peninsular Malaysia, and examined for coccidia. Intestinal tracts of 8 of the above crows wee histologically examined under light microscopy to determine the site of coccidial infection and the endogenous stages present. Fifty three (94.6%) crows had coccidial oocysts morphologically conforming to only one species of Isospora in their faeces at the time they were examined. The sporulated oocysts were found to be Isospora corviae (Ray et al. 1952) which has been emended to I. corvi. These oocysts are redescribed in greater detail. Corvus splendens is a new host record for I. corvi. Coccidial infection was observed in all the intestinal tracts and generally confined to the anterior two thirds of the intestine. The parasites occurred within intestinal epithelial cells, located usually above the host cell nucleus. Developmental stages of both the asexual and sexual phases were found in the epithelium, and are deemed to be the endogenous stages of I. corvi on the basis of the oocysts recovered from the same crows used for histological study. These stages are described here for the first time. The prevalence of I. corvi, its relationship with the host C. splendens, and its probable transmission from C. macrorhynchus are discussed.

  17. A new species of Paracapillaria (Nematoda: Capillariidae) from the intestine of the toad Duttaphrynus melanostictus (Anura) from the Malayan Peninsula
    Moravec F, Modrý D, Jirků M
    J Parasitol, 2007 Aug;93(4):907-9.
    PMID: 17918374
    A new species of parasitic nematode, Paracapillaria malayensis n. sp. (Capillariidae), is described from the small intestine of the toad Duttaphrynus melanostictus imported from the Malayan Peninsula to the Czech Republic. The new species differs from the only other congeneric species, Paracapillaria spratti, mainly in the shape and structure of the spicular proximal end (with a lobular rim), smaller eggs (45-51 x 21-24 microm), longer spicule (336 microm), and the number (37-38) of stichocytes in gravid females; whereas P. spratti parasitizes frogs of the Microhylidae in Papua New Guinea, P. malayensis is a parasite of Bufonidae in the Malayan Peninsula. Other Paracapillaria spp. are parasites of fishes, birds, or mammals and they mostly differ from P. malayensis in the structure of eggs and some other morphological features.

  18. A new species of Spauligodon (Nematoda: Oxyuroidea: Pharyngodonidae) in Cyrtodactylus bintangrendah (Sauria: Gekkonidae) from Peninsular Malaysia
    Bursey CR, Goldberg SR, Grismer LL
    J Parasitol, 2014 Jun;100(3):317-22.
    PMID: 24450328 DOI: 10.1645/13-410.1
    Spauligodon bintangensis n. sp. from the intestines of Cyrtodactylus bintangrendah (Gekkonidae) from Peninsular Malaysia is described and illustrated. Spauligodon bintangensis n. sp. represents the 51st species assigned to the genus and the first species from the Oriental Region. The new species is most similar to Spauligodon atlanticus, Spauligodon eremiasi, and Spauligodon occidentalis, but is easily separated by position of vulva, prebulbar in S. atlanticus and S. occidentalis , postbulbar in the new species, and location of lateral alae; in S. eremiasi, the lateral alae occur only in the fourth quarter of the body, whereas in the new species the lateral alae begin just posterior to lips.

  19. Prevalence of parasites in working pig-tailed Macaques (Macaca nemestrina) in Kelantan, Malaysia
    Choong SS, Mimi Armiladiana M, Ruhil HH, Peng TL
    J Med Primatol, 2019 08;48(4):207-210.
    PMID: 31025372 DOI: 10.1111/jmp.12416
    BACKGROUND: Coconut is an important commodity in Kelantan, and pig-tailed macaques (Macaca nemestrina) have been traditionally used for coconut-plucking for over a century. Most of these animals were sourced from the wild population, and the parasitic status of these macaques is unknown, plus the impacts caused by these parasites are usually underestimated by the owners.

    METHODS: A total of 30 macaques were sampled for blood, faeces and hair plucks to detect parasite.

    RESULTS: Out of 21 faecal samples examined, 11 (52%) were determined positive for one or more gastrointestinal parasites, namely Trichostrongylus spp., Strongyloides spp., Anatrichosoma spp., Capillaria spp., Trichuris spp. and Paramphisotomum spp. Filaria was detected in one (3%) of the blood samples. For ectoparasites, only lice, Pedicinus sp., were found in 9 (30%) macaques.

    CONCLUSIONS: It is imperative that the parasitic status of these animals be determined so that necessary actions and preventive measures can be implemented to prevent zoonotic transmissions.

  20. Human intestinal parasitic infection: a narrative review on global prevalence and epidemiological insights on preventive, therapeutic and diagnostic strategies for future perspectives
    Wong LW, Ong KS, Khoo JR, Goh CBS, Hor JW, Lee SM
    Expert Rev Gastroenterol Hepatol, 2020 Nov;14(11):1093-1105.
    PMID: 32755242 DOI: 10.1080/17474124.2020.1806711
    INTRODUCTION: Intestinal parasitic infection (IPI) is a global health concern among socioeconomically deprived communities in many developing countries. Many preventative strategies have been deployed to control IPI, however, there is a lack in standards on the techniques used to diagnose and monitor the prevalence of IPI.

    AREAS COVERED: The present article will review the diseases associated with IPI and discuss the current IPI control strategies such as the water, sanitation, and hygiene (WASH) interventions, community-led total sanitation (CLTS) approach, and regular anthelminthic treatments. For the first time, this review will also evaluate all currently practised diagnostic techniques for the detection of intestinal parasites and provide insights on future IPI control strategies.

    EXPERT OPINION: Advanced and improved diagnostic methods such as qPCR coupled with a high-resolution melting curve, aptamers, biosensors, and detection of extracellular vesicles can be used for detection of IPI. Vaccination against intestinal parasites can be made available to increase antibodies to interfere with the blood-feeding process by the parasites, which subsequently reduces the reproductive rates of the parasites. These methods collectively can serve as future management strategies for intestinal parasitic infections.
