Endophytic microbia are known as natural sources for producing valuable enzymes. In this study, four endophytic fungi were isolated from roots of local Catharanthus roseus (L.) G. Don var. (purple flower) and C. ocellatus (red stamens white widely grown in Nha Trang. They identified Fusarium solani RN1, Chaetomium funicola RN3, Penicillium rugulosum RN4 homopilatum WN1 based on morphologies col...

Although fish in natural populations may carry high body burdens of both organic and inorganic mercury, the effects of this divalent metal on such lower vertebrates is poorly understood. In this report, inorganic mercury in the form of mercuric chloride (HgCl2) is shown to produce both high-dose inhibition and low-dose activation of leukocytes in a marine teleost fish, Sciaenops ocellatus. Conc...

A total of 107 leptodactylid frogs representing 6 species, Leptodactylus fuscus (n 5 15), Leptodactylus leptodactyloides (n 5 9), Leptodactylus mystaceus (n 5 2), Leptodactylus ocellatus (n 5 31), Leptodactylus petersii (n 5 31), and Leptodactylus pustulatus (n 5 19), collected in the Brazilian state of Tocantins, were examined for helminths. One species of Digenea (Catadiscus marinholutzi), 6 ...
