    The usefulness of mec-associated dru typing in the epidemiological analysis of methicillin-resistant Staphylococcus aureus (MRSA) isolated in Malaysia was investigated and compared with pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), and spa and SCCmec typing. The isolates studied included all MRSA types in Malaysia. Multilocus sequence type ST188 and ST1 isolates were highly clonal by all typing methods. However, the dru typing of ST239 isolates produced the clearest discrimination between SCCmec IIIa and III isolates, yielding more subtypes than any other method. Evaluation of the discriminatory power for each method identified dru typing and PFGE as the most discriminatory, with Simpson's index of diversity (SID) values over 89%, including an isolate which was non-typeable by spa, but dru-typed as dt13j. The discriminatory ability of dru typing, especially with closely related MRSA ST239 strains (e.g., Brazilian and Hungarian), underscores its utility as a tool for the epidemiological investigation of MRSA.

    Helicobacter pylori infection of a distinct subtype of cagA may lead to different pathological manifestation. The aim of this study is to determine the presence of cagA gene and its variants in H. pylori infection among different ethnic groups and its effect on gastroduodenal diseases. Overall detection of cagA among the 205 clinical isolates of H. pylori was 94%. Variations in size of the 3' region of cagA gene were examined among 192 Malaysian H. pylori cagA-positive strains. Results showed that three cagA variants differing in fragment length of PCR products were detected and designated as type A (621-651bp), type B (732-735bp) and type C (525 bp). Although there was no association between any of the cagA subtypes with peptic ulcer disease (p>0.05), an association between cagA subtypes with a specific ethnic group was observed. Specific-cagA subtype A strains were predominantly isolated from Chinese compared to Malays and Indians (p<0.0005), and cagA subtype B strains were predominantly isolated from Malays and Indians compared to Chinese (p<0.05). The cagA type A strains of H. pylori is commonly found in the Chinese patients who have a higher risk of peptic ulcer disease, thus indicating that it could be used as an important clinical biomarker for a more severe infection.

    Turkey is the last country in the temperate zone on the edge of the European continent in which malaria is prevalent at endemic and occasionally epidemic proportions. Malaria was the most significant vector borne disease constituting a serious healthy problem until it was suppressed in 1965. Following the establishment of malaria eradication program in 1957 which began operation in 1960 after many years of malaria control, the incidence of malaria decreased annually and the stricken areas became more and more restricted. Unfortunately, an agricultural development program initiated in mid 70's in the Cukurova Plain caused a substantial migration of workers from the eastern areas where malaria at that time was more prevalent. This population movement together with the industrial expansion that took place resulted in a serious epidemic of vivax malaria in 1977 in the provinces of Adana, Icel and Hatay, where 101,867 cases were reported. The following years, Turkey targeted to reduce the number of malaria cases to less than 800 by 1984. After 1985, the number of malaria cases in the country has continued to increase and in the past five and six years a serious malaria epidemics has been building up in the southeastern provinces. The gravitational center of the disease has now moved from the Cukurova to the GAP area in South East Anatolia and beyond. The indicator of this movement is that 89% of total cases in 1998 is concerning to the GAP region. By the year 1998 the number of reported cases were 36,842. The common parasite type is P. vivax in the country. The other types are generally imported from other countries. These are Syria, S. Arabia, Pakistan, Afghanistan, Yemen, Nigeria, India, Malaysia, Ghana, Indonesia, Sudan etc. Malaria cases are registered in bordering areas of the country constantly. The suggested solutions for Malaria control in bordering areas are: 1. To establish control laboratories in customs in order to take blood from persons who come from risky areas for malaria. When positive cases are found these laboratories will also provide free treatment. 2. East country should give information about the malaria situation in their country to the other countries.

    "A tentative approximation of the expectation of life at 60-65 years, for populations with defective demographic statistics, is explored and expounded on the basis of a recent Horiuchi and [Coale] paper." The method is applied to data for El Salvador, Mexico, Puerto Rico, and Peninsular Malaysia, and it is shown that the method can be used on actual data, although it requires some drastic rounding off.

    The influenza epidemic of 2006/'07 began late in the season, like the two previous influenza epidemics. In week 8 a peak of modest height was reached. As usual, the causal strains were mainly A/H3N2 viruses and to a lesser extent A/H1N1 and B viruses. A new A/H1N1 virus variant has emerged, an event that on average takes place only every 10 years. However, almost all A/H1N1 virus isolates belonged to the old variant and were similar to the vaccine virus. The A/H3N2 virus isolates appeared to deviate from the vaccine strain, but after antigenic cartographic analysis and correction for low avidity they proved also closely related to the vaccine strain. The few type B virus isolates belonged to the B/Yamagata/16/88 lineage, whereas the used B vaccine virus had been chosen from the B/Victoria/2/87 lineage. The vaccine therefore will have provided almost optimal protection against the circulating influenza A/H1N1 and A/H3N2 viruses but not against the influenza B viruses. For the 2007/'08 influenza season the World Health Organization has recommended the following vaccine composition: A/Solomon Islands/3/06 (H1N1) (new), A/Wisconsin/67/05 (H3N2), and B/Malaysia/2506/04.

    Four species have been known to bring on human malaria, the most severe disease being caused by Plasmodium falciparum. In 2007, after returning from Malaysia, a Finnish tourist was found to be infected with a fifth Plasmodium species, P. knowlesi which usually infects macaques. Over the past few years, hundreds of human cases have been found in Malaysia. The clinical disease caused by P. knowlesi appears less severe than P. falciparum infection, but more severe than infection with other malaria-causing species. Diagnosis is based both on PCR and microscopy. P. knowlesi is currently. considered as the fifth species causing malaria in humans.

    Nipah virus (NiV), emerged in Peninsular Malaysia, caused an outbreak of severe febrile encephalitis in humans and respiratory diseases in pigs between 1998 and 1999. By May of 1999, the death of 105 humans and the culling of about 1.1 million pigs were reported. Fruitbats of Pteropid species were identified as the natural reservoir hosts. The epidemiological studies suggested that NiV was introduced into pig farms by fruitbats, and was than transmitted to humans (mainly pig farmers) and other animals such as dogs, cats and horses. In 2004, NiV reappeared in Bangladesh with greater lethality. In contrast to the Malaysia case, epidemiologic characteristics of this outbreak suggested the possibility of fruitbats-to-person, or person-to-person transmission. In this article, the epidemiological comparison between two outbreaks in Malaysia and Bangladesh, and the new-trends of virological studies of NiV will be discussed.

    Nipah encephalitis is a particular dangerous disease that affects animals and man. Fatal cases of the disease have been identified in the persons looking after pigs in the villages of Malaysia. The causative agent is presumably referred to as morbilliviruses of the Paramixoviridae family. Two hundred persons died among the ill patients with the signs of encephalitis. The principal hosts of the virus were fox-bats (Megaschiroptera) inhabiting in the surrounding forests. The present paper descries the epidemiological features of the disease, its clinical manifestations, abnormal anatomic changes, diagnosis, and implemented controlling measures.

    Melioidosis, an important diagnosis in the severely ill traveler Melioidosis is a common tropical infection in Southeast Asia and is caused by the highly pathogenic soil bacterium Burkholderia pseudomallei. Diagnosis and treatment is often challenging due to variations in clinical presentation, limited antibiotic susceptibility and high risk of recurring infection. In this report, three cases with different clinical presentations are described.

    In the past year, stool specimens of 1,732 alien laborers were examined for intestinal parasites. There was no significant difference in the positive rate between males and females. All alien laborers were examined in 3 hospitals and the positive rates were 24.8% (191/769), 13.6% (109/804) and 12.6% (20/159). Broken down by nationality, the positive rates in laborers from Thailand, Indonesia, the Philippines and Malaysia were 23.9% (192/803), 20.3% (62/305), 12.1% (60/498) and 4.8% (6/126) respectively. Of all alien laborers, 17.2% (297/1,732) had single infections of parasites and 1.3% (23/1,732) had multiple infections. Opisthorchis viverrinii was the most prevalent parasite found in infected alien laborers. 91.5% of alien laborers were aged from 21 to 40-years-old and had positive rates of parasites reaching 91.0%. The time of arrival in Taiwan had an effect in all alien laborers examined for parasites. The positive rate in laborers arriving during April to June was 22.7% which was significantly higher than the 16.3% for laborers arriving in other months.
