13. The life history of Pygidiopsis macrostomum Travassos, 1928 (Digenea: Heterophyidae)
The life history of the trematode Pygidiopsis macrostomum Travassos, 1928 is described for the first time. Rediae and cercariae were obtained from naturally infected snails Heleobia australis (d´Orbigny), a new first intermediate host. Metacercariae were found encysted in the mesenteries of three naturally infected guppies, Phalloptychus januarius (Hensel),

14. Study of crab-eating fox (Cerdocyon thous) as a definitive host for organisms belonging to sub-family Toxoplasmatinae / Estudo sobre a participação do cahorro-do-mato (Cerdocyon thous) como hospedeiro definitivo de organismos da sub-família toxoplasmatinae
Neospora caninum e Hammondia heydorni são coccídeos formadores de cistos proximamente relacionados com outros organismos heteroxenos pertencentes ao filo Apicomplexa, como Toxoplasma gondii e Hammondia hammondi. Para saber se o cachorro-do-mato (Cerdocyon thous), um canídeo silvestre comumente encontrado do nordeste da Argentina ao nordeste da América do

15. Evaluation of the viability of sporulated oocysts of Neospora caninum under different temperature and disinfectants treatments / Avaliação da viabilidade de oocistos esporulados de Neospora caninum a diferentes condições de temperatura e ação de desinfetantes
Neospora caninum is an Apicomplexan parasite that causes neuromuscular disorders in dogs and abortion in cattle. Dogs and coyotes are the only species identified as definitive hosts. The sexual phase of the N. caninum life cycle occurs within the host, and results in the shedding of oocysts in the feces that will sporulate in the environment and become infec

16. Aspectos clínicos, diagnósticos e tratamentos da estefanofilariose em vacas leiteiras
Stephanofilariasis is a worldwide disease caused by the nematode Stephanofilaria spp that determines skin lesions in several definitive hosts. The prevalence is higher in summer due to the increase in fly population, the intermediate host. In cattle, the chronic dermatitis is characteristic begining with papules that progress to nodules, alopecia and ulcers

17. Avaliação da resistência à Leifsonia xyli subsp. xyli, agente causal do raquitismoda- soqueira (RSD), em variedades comerciais de cana-de-açúcar / Resistance of sugarcane commercial cultivars to Leifsonia xyli subsp. xyli; the causal agent of the ratoon stunting disease (RSD)
Sugarcane (Saccharum ssp.) is one of the most important cultures in the history of the humanity. The center of origin is probably New Guinea, where people had the first contact with the plant in wild state. Presently, Brazil leads the list of the 80 sugarcane producing countries. Brazil is also the first in exporting sugarcane by-products, followed by Austra

18. Intermediate and definitive hosts of Schistosoma mansoni in Corrientes province, Argentina
Corrientes province is located in the humid subtropical region of Argentina northeast on the left riverbank of Paraná River in the border with the South of Brazil. This is a region without schistosomiasis but planorbid and rodents that would serve as host of the life cycle of Schistosoma mansoni inhabit here. The objective of this work is to know the role o

Lagochilascariasis is an infection caused by a parasite from the genus Lagochilascaris and the species is Lagochilascaris minor Leiper 1909 Campos et al (1992) described its experimental evolutive cycle using a model constituted by mice as intermediate hosts and by domestic cats as definitive hosts The availability of murine strains with different genetic ch

21. Experimental evidence and ecological perspectives for the adaptation of Schistosoma mansoni Sambon, 1907 (Digenea: Schistosomatidae) to a wild host, the water-rat, Nectomys squamipes Brants, 1827 (Rodentia: Sigmodontinae)
Due to the semi aquatic habits and the overlap of the geographical distribution of the water-rat, Nectomys spp., with schistosomiasis endemic areas, these wild rodents are very likely to acquire Schistosoma mansoni infection in their daily activities. The role of the water-rat in the S. mansoni cycle would be substantiated if one could prove that these roden

22. Desenvolvimento biológico de Angiostrongylus vasorum (Baillet) Kamensnky (Nematoda, Angiostrongylidae) em Subulina octona Bruguière (Molusca, Subulinidae) em condições de laboratório
With the purpose of investigating the biological aspects of Angiostrongylus vasorum (Baillet, 1866) Kamensky, 1905 in Subulina octona Bruguiere, 1789 experimental infections were carried out with the exposure of 90 adult molluscs to 155 L1 of the parasite/mollusc during 24 hours. The intramollus-can larval development was checked out daily through the chemic

23. Sarcocystis spp. in Human Infections
Sarcocystis species are intracellular protozoan parasites with an intermediate-definitive host life cycle based on a prey-predator relationship. Asexual stages develop in intermediate hosts after they ingest the oocyst stage from definitive-host feces and terminate with the formation of intramuscular cysts (sarcocysts). Sarcocysts in meat eaten by a definiti

24. Evidence for the recent horizontal transfer of long terminal repeat retrotransposon
The evolutionary dynamics existing between transposable elements (TEs) and their host genomes have been likened to an “arms race.” The selfish drive of TEs to replicate, in turn, elicits the evolution of host-mediated regulatory mechanisms aimed at repressing transpositional activity. It has been postulated that horizontal (cross-species) transfer may be
