Soil-Transmitted Helminthiasis: A Critical But Neglected Factor Influencing School Participation Of Aboriginal Children In Rural Malaysia, Init Ithoi
Init Ithoi
Soil-transmitted helminthiasis (STH), among the most common neglected tropical diseases, is a major public health problem in Malaysia with a possible impact on the nutritional status and school participation of rural children. This study was carried out among Aboriginal schoolchildren, living in an endemic area for STH in Malaysia, to determine the possible relationship between intestinal helminthiasis and school absenteeism. We also evaluated whether successful treatment of the infection will affect school attendance among the subjects. Stool analysis revealed that more than 90% of the subjects were infected with at least 1 helminth species, with Ascaris lumbricoides and Trichuris trichiura …
Seroepidemiology Of Toxoplasmosis In Renal Patients Seroepidemiology Of Toxoplasmosis In Renal Patients, Init Ithoi
Seroepidemiology Of Toxoplasmosis In Renal Patients Seroepidemiology Of Toxoplasmosis In Renal Patients, Init Ithoi

Toxoplasmosis is an important parasitic disease in immunosuppressed patients. This prospective study was conducted to determine the seroprevalence, associated risk factors and the incidence of clinically confirmed toxoplasmosis among renal patients at the University of Malaya Medical Center, Kuala Lumpur, Malaysia. We interviewed 247 renal patients, each of whom answered an epidemiological questionnaire, and collected blood samples for measurement of anti-Toxoplasma IgG and IgM antibodies by ELISA. Overall seroprevalence of latent toxoplasmosis was observed in 126 (51%) renal patients. Race (Malays), marital status (married) and primary level of education, were all factors associated with a greater chance of Toxoplasma infection. …
Cloning And Expression Of Toxoplasma Gondii Dense Granular Protein 4 (Gra4) In Pichia Pastoris, Init Ithoi
Cloning And Expression Of Toxoplasma Gondii Dense Granular Protein 4 (Gra4) In Pichia Pastoris, Init Ithoi
Init Ithoi
GRA4 of Toxoplasma gondii has been shown to prompt IgG, IgM and IgA responses in previous studies and is thus considered one of the major immunogenic proteins from T. gondii that can be used for both diagnostics purposes and vaccine development. This study seeks to clone and express the GRA4 in Pichia pastoris, which has numerous advantages over other systems for expression of eukaryotic proteins. In order to achieve this, the gene was cloned into the pPICZ alpha A expression vector, which was then incorporated into the P. pastoris genome via insertional integration for expression of the recombinant protein, under …
Occurrence Of Giardia And Cryptosporidium (Oo)Cysts In The River Water Of Two Recreational Areas In Selangor, Malaysia, Init Ithoi
Init Ithoi
This study is the first report on the occurrence of Giardia and Cryptosporidium (oo)cysts in recreational rivers water from Malaysia. It was carried out in water samples at two rivers, 'Sungai Congkak' and 'Sungai Batu', located in Selangor State. The occurrence of both Giardia lamblia and Cryptosporidium parvum (oo)cysts was higher in Sungai Congkak (50% or 15/30 and 10% or 3/30 respectively) than Sungai Batu (16% or 5/30 and 3.3% or 1/30 respectively). The mean density of cysts/L was 0.72 in Sungai Congkak and 0.023 in Sungai Batu, and that of oocysts/L was 0.023 in Sungai Congkak and 0.0033 in …
Glycerol With Fetal Calf Serum - A Better Cryoprotectant For Blastocystis Hominis, Init Ithoi
Glycerol With Fetal Calf Serum - A Better Cryoprotectant For Blastocystis Hominis, Init Ithoi
Init Ithoi
In recent years, a growing number of reports have sug- gested that the protozoan parasite, Blastocystis hominis (Brumpt 1912), is a pathogenic cause of diarrhoea. It is imperative, however, that more studies are conducted on the various human isolates of the parasite before in- criminating it is a pathogen. In our laboratory we maintain human and animal isolates of Blastocystis using the monophasic medium Iscove's Modi®ed Dul- becco Medium (IMDM) as established by Ho et al. (1993), but maintaining continuous cultures is tedious, time consuming and expensive, and the parasites may be prone to genetic drift. There is therefore a …
