Southeast Asian J. Trop. Med. Public Health, 1980 Dec;11(4):566-71.

Comparative studies of vector efficiency were done with the Liverpool and Malaysian strains of Aedes (Finlaya) togoi for subperiodic Brugia malayi and Brugia pahangi. The Malaysian strain of A. togoi was found to take in fewer microfilariae under the same experimental conditions than the Liverpool strain. Also, for various microfilarial densities in the host's peripheral blood, the Malaysian strain had less mean infective larvae per fed mosquito than the Liverpool strain. The microfilarial intake of A. togoi was not affected by the site of feeding on the host affected by the site of feeding on the host. Most of the mosquitoes took in fewer microfilariae than expected. It is concluded from these studies that the Malaysian strain of A. togoi is a susceptible and reasonably good vector for subperiodic B. malayi and B. pahangi. Further field studies should be carried out to determine its importance as a natural vector of Brugian filariasis.

Fulltext Review of toxoplasmosis in Malaysia

PMID: 1822863

Various studies on toxoplasmosis in Malaysia have shown that specific antibodies to Toxoplasma gondii are common among Malaysians. Among the ethnic groups, the Malays have the highest prevalence rate followed by Indians, Orang Aslis (aborigines) and Chinese. Antibody is acquired early in life and increases with age. There is no significant difference in the prevalence rate between males and females. The disease is apparently more prevalent among rural dwellers and those in the lower socioeconomic group. It appears that the prevalence rate is also influenced by environmental conditions, occupation, diet and cultural habits. Studies with animals have shown the presence of antibody to T. gondii, but this does not seem to be the source of infection since Malaysians normally cook their meat well.

The recovery of six adult Gnathostoma spinigerum Owen, 1936 from a civet cat, Prionodon linsang Hardwick, constitutes the second reported record of this parasite and the first authenticated case of adult worms found in a wild animal from Malaysia. The food habits of the infected P. linsang as an important link in the transmission of G. spinigerum in the intermediate and definitive hosts together with the probable distribution of this parasite are discussed.

Experimental infection of Rattus sabanus and Rattus muelleri with subperiodic Brugia malayi

Sivanandam S, Mak JW, Lai PF

Southeast Asian J. Trop. Med. Public Health, 1975 Mar;6(1):68-73.

PMID: 1145240

R. sabanus and R. muelleri are very common in the lowland forests of Malaysia. In nature they are infected with Breinlia sp. and D. ramachandrani. In an attempt to determine whether they are also susceptible to subperiodic B. malayi and thereby being potential reservoirs of infection of the disease, 24 R. muelleri and 17 R. sabanus were experimentally infected with the parasite. Results show that although they can support the full development of the parasite, they are poor hosts. This confirms the observation that in Malaysia natural infection of Rattus spp. with the parasite has not been seen. These rats therefore are probably not important in the zoonotic transmission of subperiodic B. malayi in Malaysia.

Sarcocystis booliati n.sp. and a parasite of undetermined taxonomic position, Octoplasma garnhami n. gen. n. sp., from the moonrat, Echinosorex gymnurus

Dissanaike AS, Poopalachelvam M

Southeast Asian J. Trop. Med. Public Health, 1975 Jun;6(2):175-85.

PMID: 809845

Sarcocystis booliati n.sp. is described from the moonrat Echinosorex gymnurus (Mammalia, Insectivora) from West Malaysia. The cysts are very thin-walled, not visible to the naked eye, and have no trabeculae or cytophaneres. They are found in skeletal but not heart muscle. The zoites are small, 5-8 by 2-3 mum with a mean of 6.5 by 2.2 mum, in dry fixed smears. Octoplasma garnhami n.gen. n.sp., a parasite of undetermined taxonomic status but belonging to the Coccidiasina, Apicomplexa, is also described from the same host. Only schizononts and pseudocysts with typically 8 zoites, have so far been seen in monocytes of the spleen and liver. The zoites are large, 15 by 3 mum and have a distinct nucleolus even in dry-fixed smears.

Fulltext Cat scratch disease: a diagnostic dilemma

Lina LC, Rosalind S, Chong AW, Toha A, Shaffie B

Med J Malaysia, 2010 Jun;65(2):155-6.

PMID: 23756805 MyJurnal

Cat scratch disease (CSD) caused by Bartonella henselae is the most common Bartonella infection worldwide. CSD usually presents as self-limiting lymphadenitis characterized by lymphadenopathy that occurs after contact with a cat and the symptoms resolve within 2 to 4 months. Serology testing is the cornerstone of diagnosis. However, it may require the use of clinical specimens for microbiologic evaluation for diagnosis. A number of antimicrobial agents have been advocated for the treatment of cat-scratch disease and treatment with azithromycin has been shown to be beneficial.

PMID: 6544939

Toxoplasmosis is a parasitic infection of worldwide distribution. It is caused by an obligate intracellular parasite, Toxoplasma gondii. The commonest form of this disease is the acquired simple lymphadenopathy. Such a case is described and the clinicopathological significance of the disease is discussed.

Fulltext Experiments with banana trunk juice as a neuromuscular blocker

Lee SK, Ng LL, Lee SI

Med J Malaysia, 1980 Jun;34(4):423-5.

PMID: 7219276

The juice of the banana trunk produces a nondepolarising neuromuscular block. Oxygenation of
the extract enhances its potency. Reversal with anticholinesterase is transient. Partial reversals in isolated preparations indicate there could be both specific and non-specific binding which could account for blockade after washing. It could be specifically bound to ACh receptors in an irreversible way. Its action appears similar to that of alpha-BuTX from the venom of the banded krait. Purification of the extract and subsequent investigations will support present findings and present the characteristics fully.

The association of allergy and chronic suppurative otitis media: A study in a tropical country

Mohd Khairi MD, Shahrjerdi B, Ramiza RR, Normastura R

Med J Malaysia, 2019 Jun;74(3):205-208.

PMID: 31256174

OBJECTIVE: Chronic suppurative otitis media (CSOM) usually begins as a spontaneous perforation of tympanic membrane due to an acute infection of the middle ear. This study was aimed to evaluate the association between allergy and CSOM.

METHODS: A case-control study was carried out among patients with CSOM (cases) and controls were those with no ear pathology. The presence of CSOM was made through a medical history and otoscopic examination. Allergen testing was done by the skin prick test.

RESULTS: In all 124 subjects were recruited in this study with equal number of the cases and controls. The commonest positive reaction in the skin prick test in both groups was to house dust mites. Among CSOM cases, half (50%) of them had an allergy to Blomia tropicalis and 48.4% to Dermatophagoides while in the control group, 27.4% to Dermatophagoides and 25.8% to B. tropicalis. There were significant associations between CSOM and allergy to B. tropicalis (p=0.005), Dermatophagoides (p=0.016) and Felis domesticus (p=0.040). The prevalence of allergy at 95% confidence interval (95%CI) in CSOM and control groups were demonstrated as 59.7% (95%CI: 47.5, 71.9) and 30.6 % (95%CI: 19.1, 42.1) respectively. There was a significant association between allergy and CSOM (p=0.001).

CONCLUSION: Indoor allergens are the most prevalent in our environment and therefore good control may difficult to achieve. The hypersensitivity states of the subject are likely to have a role in the pathogenesis of CSOM especially in the tropical countries where allergy occurs perennially.
