Cytological and cytogenic effects induced by thiabendazole on Allium cepa root meristem JBAG
Andrioli,Nancy B; Mudry,Marta D.
The toxicity and genotoxicity of thiabendazole (TBZ) in its commercial formulation Foldan® was studied in Allium cepa meristematic cells at concentrations ranging between 10 and 250 µg / ml. Our results show that exposure to TBZ induces a significant increase in the frequency of anaphase telophase chromosomal aberrations, micronuclei and binucleated cells at all the concentrations of TBZ assayed. The frequency of anaphase telophase aberrations was observed to reach a plateau at the concentration of 50 µg / ml of TBZ, which could be probably due to TBZ mitotic toxicity manifested at concentrations of 100 and 250 µg / ml. An increase was also observed in the rate of metaphase and anaphase, which was, in turn, indicative of alterations in chromatid...

Intestinal parasites of Alouatta caraya (Primates, Ceboidea): preliminary study in semi-captivity and in the wild in Argentina Mastozool. neotrop.
Milozzi,Carola; Bruno,Gabriela; Cundom,Elisa; Mudry,Marta D; Navone,Graciela T.
Endoparasitic infections are common in nonhuman primates and important factors in regulating their natural populations. Primates are particularly vulnerable to the infections of directly transmitted parasites because they often live in close social groups that facilitate their transmission. The main objective of this study was to provide baseline data on gastrointestinal parasites of semi captive and wild howler monkeys Alouatta caraya troops from Argentina. We collected 110 fecal samples from 38 howler monkeys from four troops, two of them kept in semi-captivity at the CRMAN, Córdoba, and two wild troops from Las Lomas, Corrientes. We identified six species of parasites: four Protozoa, Giardia lamblia, Blastocystis hominis, Eimeria sp. and Entamoeba coli;...
