The present paper reviews the health problems of rural agricultural workers in Malaysia. As is common with most developing countries, the agricultural sector forms the pillar of the national economy in Malaysia, the major products being rubber, palm oil, rice and timber. Most of the agricultural workers, who form the largest occupational group in the country, live in the rural areas under poor socioeconomic and environmental conditions. Their general health problems include large families, substandard housing, overcrowding, lack of piped water supply and sanitary excreta disposal, malnutrition and prevalent diseases such as cholera, typhoid, dysentery and parasitic infections. The specific occupational health problems include infectious diseases, agricultural accidents, pesticide poisonings, physical hazards, keratitis nummularis and snake-bites. The organization of agricultural health services in developing countries is also discussed.

The epithelium represents the first and most extensive line of defence against pathogens, toxins and pollutant agents in humans. In general, pathogens have developed strategies to overcome this barrier and use it as an entrance to the organism. Entamoeba histolytica, Naegleria fowleri and Acanthamoeba spp. are amoebae mainly responsible for intestinal dysentery, meningoencephalitis and keratitis, respectively. These amoebae cause significant morbidity and mortality rates. Thus, the identification, characterization and validation of molecules participating in host-parasite interactions can provide attractive targets to timely intervene disease progress. In this work, we present a compendium of the parasite adhesins, lectins, proteases, hydrolases, kinases, and others, that participate in key pathogenic events. Special focus is made for the analysis of assorted molecules and mechanisms involved in the interaction of the parasites with epithelial surface receptors, changes in epithelial junctional markers, implications on the barrier function, among others. This review allows the assessment of initial host-pathogen interaction, to correlate it to the potential of parasite invasion.
