This study is the first report of an infestation amoeba in gills asymptomatic Oreochromis sp. from Manir River, Terengganu, Malaysia. The results confirmed presence two species amoeba, Vermamoeba vermiformis and Tetratmitus sp., based on 18 ribosomal RNA gene sequences with 99% sequence similarity. Morphological observations using light scanning electron microscopy supported findings, demonstra...

Members of the genus Acanthamoeba are usually free-living amebae and are found in a variety of ecological niches including soil, fresh and brackish water, dust in air, filters of heating, ventilating, and air conditioning units, swimming pools and hot tubs, etc. Occasionally, they are also known to cause central nervous system infections in humans and other animals. We isolated into culture an ...

Legionella pneumophila is a bacterial pathogen present in aquatic environments that can cause a severe pneumonia called Legionnaires' disease. Soon after its recognition, it was shown that Legionella replicates inside amoeba, suggesting that bacteria replicating in environmental protozoa are able to exploit conserved signaling pathways in human phagocytic cells. Comparative, evolutionary, and f...

The application of electron microscope autoradiography to Amoeba proteus cells labeled with tritiated thymidine has permitted the identification of morphologically distinct particles in the cytoplasm as the sites of incorporated DNA precursor. The particles correspond to those previously described from light microscope studies, with respect to both H(3)Tdr incorporation and distribution in cent...

Hopkins Hospital Reports. Vol.11. Nos. 7,8,9. Report in Pathology, I. Amoebic Dysentery. By William T. Councilman, M.D., and Henri A. Lafleur, M.D. Pp. 156. Baltimore: The Johns Hopkins Press. 1891. The amoeba hitherto has been a useful ally of the physiologist in elucidating the properties of protoplasm and in demonstrating the simplest phenomena of life; but only recently has it been shown to...
