A study was conducted in Jakarta on 903 women workers before going abroad through stool examination by Ritchie's technical method. Of the women workers studied, 640 subjects (70.87%) were found to be infected with intestinal parasites either helminthes, protozoa or combination. Out of those infected, 451 (70.47%) subjects were infected with intestinal helminthes, namely Ascaris lumbricoides (38.13%), Trichuris trichiura (28.13%), a combination of Necator americanus and Ancylostoma duodenale (13.59%) and Enterobius vermicularis (4.84%). In addition 319 (49.84%) subjects were infected with intestinal protozoa namely Giardia lamblia (22.03%), Entamoeba histolytica (14.53%), Blastocystis hominis (6.56%) and Entamoeba coli (6.72%). The youngest age to be affected was 14 years old (14.19% of the subjects studied). Majority (72.09%) of the study subjects received junior high school level of education. Home yard (46.51%) and ground under the trees (22.09%) were places favourable for the habits of defaecation, whereas garbage disposal took place in 52.33% home yards and 25.58% creeks. This study revealed that various life style habits and indiscriminate defaecation were the causes of the continuous transmission of intestinal parasitic infections. The different parasites that were found in women workers before going abroad relate to the various epidemiological aspects of intestinal parasites in women workers in Indonesia who came from different islands in the country and possessed different life style patterns, socioeconomic status, geographical condition and cultures.

The CNS Infection Censuses for 2011 and 2012 from 9 neurology training programs in 7 institutions in the Philippines were collated to determine the types of CNS infections seen in the country and their relative frequencies. A comparison with a similar survey done in 1999 was made. A total of 1629 cases of CNS infections were recorded. There were 23 categories. Bacterial meningitis (34.3%) and TB meningitis (30.7%) were the top two infections, constituting more than half of all CNS infections seen. When the adult and pediatric census were separated, TB meningitis came up to be the most common infection in adults (43%) with bacterial meningitis a poor second at 19.4%. The reverse is seen in the pediatric population – bacterial meningitis (41.7%) vs. TB meningitis (24.6%). Cryptococcal meningitis was more frequent in the adult census (8.1%) compared with the pediatric census (0.1%). These patterns were seen in a similar census done in 1999. A significant increase in relative frequency in cryptococcal cases was seen in the later census (2.8% vs. 2.0%), the increase being due to the marked increase in the adult group (8.1% vs. 4.3%), probably due to the upward trend in the incidence of HIV cases in the country. No increase in this category was seen in the pediatric population. The benefits of collaboration among institutions in coming up with a large number of cases of CNS infections and a greater variety to study was highlighted. The study was conducted by the CNS Infection Council of the Philippine Neurological Association.

The objective was to estimate the prevalence of intestinal protozoa among the aborigines and to determine the problems regarding the infection. The study was carried out in January 2006 in Pos Senderut, Pahang, Malaysia. Samples of faeces were collected from children and adults and these were fixed in PVA and trichrome staining was carried out. From the 130 individuals studied, 94 (72.3%) were positive with at least one intestinal protozoa. Nine intestinal protozoa namely Blastocystis hominis, Giardia lamblia, Entamoeba histolytica, Entamoeba coli, Endolimax nana, Entamoeba hartmani, Entamoeba polecki, Iodamoeba butschlii and Chilomastix mesnili were detected. The prevalent species were B. hominis (52.3%), followed by G. lamblia (29.2%), E. coli (26.2%) and E. histolytica (18.5%). The other species ranged from 1.5 to 10.8%. Among the positive samples, mixed infection with E. histolytica and G. lamblia was 3.8%, E. histolytica and B. hominis was 15.4%, G. lamblia and B. hominis was 17.7%. Triple infection of E. histolytica, G. lamblia and B. hominis was 3.1%. The infection was more prevalent in children below 10 years age group (45.4%) and lowest in the age above 60 years (3.8%). The high prevalence was attributable to poor environmental management, poor personal hygiene and lack of health education.

Amoebiasis is an infectious diseased caused by parasitic one-celled protozoan called Entamoeba histolytica. Numerous protozoa also can inhabit the gastro-intestinal tract of human. Majority of these protozoa are non-pathogenic commensals or only causes disease under certain circumstances. Morphologically, E. histolytica, the invasive form, share the same characteristic with the nonpathogenic form, E. dispar. Both strains can be distinguished by using DNA identification. Many previous researches in Malaysia only reported infection with E. histolytica infection. Therefore in this study we tried to classify infection among the aborigines in Cameron Highland as true E. histolytica or E. dispar by Nested Polymerase Chain Reaction (Nested PCR) and Restriction enzyme (RE) digestion. Results showed that 31 samples were positive by microscopic examination, however of these 28 (13.2%) samples were positive for E. histolytica and 12 (5.6%) samples were positive for E. dispar by molecular tools.

Among various genera of free-living amoebae prevalent in nature, some members are identified as causative agents of human encephalitis, in which Naegleria fowleri followed by Acanthamoeba spp. and Balamuthia mandrillaris have been successively discovered. As the three dominant genera responsible for infections, Acanthamoeba and Balamuthia work as opportunistic pathogens of granulomatous amoebic encephalitis in immunocompetent and immunocompromised individuals, whereas Naegleria induces primary amoebic meningoencephalitis mostly in healthy children and young adults as a more violent and deadly disease. Due to the lack of typical symptoms and laboratory findings, all these amoebic encephalitic diseases are difficult to diagnose. Considering that subsequent therapies are also affected, all these brain infections cause significant mortality worldwide, with more than 90% of the cases being fatal. Along with global warming and population explosion, expanding areas of human and amoebae activity in some regions lead to increased contact, resulting in more serious infections and drawing increased public attention. In this review, we summarize the present information of these pathogenic free-living amoebae, including their phylogeny, classification, biology, and ecology. The mechanisms of pathogenesis, immunology, pathophysiology, clinical manifestations, epidemiology, diagnosis, and therapies are also discussed.

After bathing at a hot spring resort, a 75-year-old man presented to the emergency department because of seizure-like attack with loss of conscious. This is the first case of primary amebic meningoencephalitis (PAM) caused by Naegleria fowleri in Taiwan. PAM was diagnosed based on detection of actively motile trophozoites in cerebrospinal fluid using a wet-mount smear and the Liu's stain. The amoebae were further confirmed by PCR and gene sequencing. In spite of administering amphotericin B treatment, the patient died 25 days later.

Primary amebic encephalitis (PAM) is a devastating central nervous system infection caused by Naegleria fowleri, a free-living amoeba, which can survive in soil and warm fresh water. Here, a 43-year-old healthy male was exposed to warm freshwater 5 days before the symptom onset. He rapidly developed severe cerebral edema before the diagnosis of PAM and was treated with intravenous conventional amphotericin B while died of terminal cerebral hernia finally. Comparing the patients with PAM who has similar clinical symptoms to those with other common types of meningoencephalitis, this infection is probably curable if treated early and aggressively. PAM should be considered in the differential diagnosis of purulent meningoencephalitis, especially in patients with recent freshwater-related activities during the hot season.
