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.

Isospora corvi Ray, Shivnani, Oommen and Bhaskaran, 1952 from the common house crow (Corvus splendens Vieillot) of Selangor, peninsular Malaysia

Poon SK, Chew WK

Folia Parasitol., 1991;38(3):201-7.

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.

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.

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.

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.

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.

Gastrointestinal parasites of zoonotic importance observed in the wild, urban, and captive populations of non-human primates in Malaysia

Adrus M, Zainudin R, Ahamad M, Jayasilan MA, Abdullah MT

J Med Primatol, 2019 02;48(1):22-31.

PMID: 30370934 DOI: 10.1111/jmp.12389

BACKGROUND: A study was undertaken to determine gastrointestinal (GI) parasites commonly found in Malaysia's non-human primates (NHP) living in three different types of populations (wild, urban, and captive) and the basis of major GI parasites of zoonotic importance.

METHODS: A total of 308 samples was collected and microscopically screened from the NHP in the wild (n = 163), urban (n = 76), and captive (n = 69) populations. The samples were taken from 12 species of local NHPs.

RESULTS: At least, 44 species of GI parasites comprising of protozoans (seven species), nematodes (26 species), cestodes (five species), trematodes (five species), and pentastomida (one species) were detected. There were no significant differences for the overall prevalence and no great differences in GI parasite species among the wild, urban, and captive NHP populations.

CONCLUSION: The most common GI parasite was Ascaris spp. (49.7%), followed by Oesophagostomum spp. (26.9%), and 31 species discovered in this study are of known public health importance.

Evaluation of the detection method by a flotation method using a wire loop for gastrointestinal parasites

Takano A, Morinaga D, Teramoto I, Hatabu T, Kido Y, Kaneko A, et al.

Vet Med Sci, 2024 Sep;10(5):e70007.

PMID: 39207196 DOI: 10.1002/vms3.70007

Infections by gastrointestinal parasites are found in a variety of animals worldwide. For the diagnosis of such infections, the flotation method is commonly used to detect parasitic microorganisms, such as oocysts or eggs, in feces. Instead of adding a flotation solution after the final centrifugation step and using a cover slip to collect the parasites, the method using a wire loop for the recovery of the organisms has been reported as one of alternative methods. However, the recovery rates of microorganisms from the flotation method have not been analysed. In the present study, the utility of a flotation method with the use of a wire loop of 8 mm in diameter (the loop method) was evaluated using different numbers of E. tenella oocysts and Heterakis gallinarum eggs, and chicken fecal samples collected at the farms. Consequently, we found that the oocysts and eggs in tubes could be collected at a ratio of 2.00 to 3.08. Thus, our results indicate that the loop method is a simple and time saving method, implicating the application for the estimated OPG/ EPG (Oocysts/Eggs per gram) of the samples.

Hesham MS, Edariah AB, Norhayati M

Med J Malaysia, 2004 Jun;59(2):284-93.

PMID: 15559182

Malnutrition including vitamin A and iron deficiency and parasitic diseases have a strikingly similar geographical distribution with the same people experiencing both insults together for much of their lives. Parasitic infections are thought to contribute to child malnutrition and micronutrient deficiency through subtle reduction in digestion and absorption, chronic inflammation and loss of nutrients. Parasites may affect the intake of food; it's subsequent digestion and absorption, metabolism and the maintenance of nutrient pools. The most important parasites related to nutritional status are intestinal parasites especially soil transmitted helminthes, Giardia duodenalis, Entamoeba histolytica, followed by other parasites such as the coccidia, Schistosoma sp. and malarial parasites.

Sagin DD, Ismail G, Mohamad M, Pang EK, Sya OT

Southeast Asian J. Trop. Med. Public Health, 2002 Jun;33(2):373-7.

PMID: 12236440

A cross-sectional survey of 365 individuals, (51.9% males, 48.1% females; ages 5-85 years), from five remote interior communities in upper Rejang River basin Sarawak, Malaysia, found 24.4% were anemic. The range and mean of Hb concentration in male and female were: 7.2-17.0 mg/ml and 13.7 mg/ml and 7.9-15.7 mg/ml and 12.9 mg/ml respectively. Amongst the five tribes surveyed, the prevalence of anemia (range: 10.6-46.7%), was higher among the Penans (46.7%), Kenyahs (31.1%), Kajangs (27.8%) and Kayans (19.3%), than amongst the Ukits (10.6%). Anemia is more common among males >40 years and among adolescents and young reproductive females, as well as elderly females > 61 years old. Of the 83 anemic individuals, 6.0% and 3.6% had Trichuris trichiura or hookworm respectively; however there is no clear association with intestinal worm infection.

Southeast Asian J. Trop. Med. Public Health, 1992 Dec;23(4):578-86.

PMID: 1298065

Intestinal protozoa are found in all communities in Malaysia and among all ethnic groups. Prevalence of intestinal protozoa is not affected by ethnicity but by living conditions. Communities with both basic amenities of safe water supply and proper toilets have lower prevalence than those with one or none of the amenity. Cryptosporidium is an important intestinal protozoon in Malaysia and should be included in future field and laboratory studies and also in laboratory diagnosis for pathogens. Much interest will be centered on Blastocystis hominis in future studies in view that it may be a cause of diarrhea.

Trop Gastroenterol, 1991 Jan-Mar;12(1):21-4.

PMID: 2058006

In a study to test the association between soil transmitted intestinal helminthiasis and abdominal symptoms in a non-paediatric age group, 242 randomly selected patients (137 males, 105 females, median age 45 years) were asked specific questions pertaining to abdominal symptoms at the time of admission to the adult medical wards. Stool examination on all patients revealed a round worm prevalence rate of 21%. A larger proportion of stool positive female patients were symptomatic than stool negative females (68% vs 30%, p = 0.04). There was no significant difference in symptoms between stool positive and stool negative male patients (34.6% vs 31%, p = 0.91). The results suggested an association between intestinal nematode infection and abdominal symptoms in females but not in males.
