Doenças de peixes: profilaxia, diagnóstico e tratamento

Fauna parasitária de Leporinus lacustris e Leporinus friderici (Characiformes, Anostomidae) da planície de inundação do alto rio Paraná, Brasil - DOI: 10.4025/actascibiolsci.v28i3.228

The main difference in the parasite fauna was the use rate of the host by some shared parasite species, represented by abundance, which differed in the fish species showing that, although all are appropriate hosts, their exploitation occurs in different ways.

Composição e estrutura das infracomunidades endoparasitárias de Gymnotus spp. (Pisces: Gymnotidae) do rio Baía, Mato Grosso do Sul, Brasil - DOI: 10.4025/actascibiolsci.v26i4.1527

Diversity of the infracommunities of male and female hosts were not different, but influence of hosts' sex in the prevalence and abundance of Tylodelphys sp.

Relação parasito-hospedeiro em peixes de pisciculturas da região de Assis, Estado de São Paulo, Brasil. 2. Piaractus mesopotamicus (Holmberg, 1887)

It is shown that only in the fish farming of Palmital, Sao Paulo State, a positive correlation occurred between the standard length and the abundance of parasitism and the results of the relative condition factor show that despite of the high prevalence of the species, few of them are abundant.

Relação parasito-hospedeiro em peixes de pisciculturas da região de Assis, Estado de São Paulo, Brasil. 1. Oreochromis niloticus (Linnaeus, 1757) - DOI: 10.4025/actascibiolsci.v29i2.594

It was possible to observe that all fish farms presented the same parasite fauna; however, each farm featured its own peculiar community structure.

Carga parasitária de Rondonia rondoni , Travassos, 1920 (Nematoda, Atrictidae) e fator de condição do armado, Pterodoras granulosus , Valenciennes, 1833 (Pisces, Doradidae) - DOI:…

It is concluded that despite of variations in the length, between males and females, the sex does not influence in the intensity and prevalence of infection.

Aspectos ecológicos da fauna endoparasitária de Acestrorhynchus lacustris (Lütken, 1875) (Characiformes, Acestrorhynchidae) da planície de inundação do alto rio Paraná, Brasil - DOI:…

There was significant difference in the prevalence and abudance of infection of Q. torquatus between hosts sexes and there was significant positive correlation between the prevalence of Contracaecum Type 1 and host standard length.

Produção e caracterização de um marcador potencial de linfócitos T em surubim híbrido (Pseudoplatystoma corruscans X P. fasciatum) - DOI: 10.4025/actascibiolsci.v26i2.1636

Seu uso em imunohistoquimica permitiu tambem a localizacao de linfocitos T no timo e baco, demonstrando assim o seu potencial para estudar a ontogenia do sistema imune dos surubins.

It registers new occurrences of this metacercariae infecting the eyes of four new hosts of fish, Serrasalmus maculatus collected in the Rosana reservoir in the Paranapanema river and Hypostomus regani, Schizodon borellii and Auchenipterus osteomystax collection in the the Upper Parana River floodplain.
