Molecular Characterization and Biochemical and Histopathological Aspects of the Parasitism of Haemoproteus spp. in Southern Caracaras (Caracara plancus).

Haemoproteid species have a wide global distribution, and they have been described in falcon species in several parts of the world. However, few studies in South America have focused on these birds. Haemoproteus spp.

Hepatic profile of Gallus gallus Linnaeus, 1758 experimentally infected by Plasmodium juxtanucleare Versiani & Gomes, 1941.

One of the species that causes avian malaria is Plasmodium juxtanucleare. It is commonly found in poultry, especially when the birds receive food free of coccidiostats. Since industrial and organic poultry breeding is increasing in the world and few studies have been conducted examining the clinical parameters of both healthy and infected birds, this work evaluated whether the infection caused by P.

The influence of the fasting period on the number of nymphal instars and on the sex ratio of Argas (Persicargas) miniatus (Acari: Argasidae).

The current study investigated the biology of nymphs of the first and second instars of Argas (Persicargas) miniatus. Nymphs were deprived of food for 15, 30 or 60 days and held at 27 ± 1 °C and 80 ± 10% relative humidity (controlled conditions) or at room conditions of temperature and relative humidity. Nymphs of first instar deprived of food for 15 or 30 days molted to second and third instars in both controlled and room conditions.

Antimalarial activity of the novel quinoline/6-thiopurine conjugate in Gallus gallus Linnaeus, infected experimentally by Plasmodium (Novyella) juxtanucleare.

This study aimed to evaluate the 4-(6'-thiopurine)-7-chloroquinoline, a novel quinoline/6-thiopurine conjugate, for the treatment of Gallus gallus experimentally infected with Plasmodium juxtanucleare, an avian malaria agent. The avian group treated with 4-(6'-thiopurine)-7-chloroquinoline showed a significative parasite clearance and maintained a low level of parasitaemia, when compared with the untreated control group and to the chloroquine treated avian group.

[Malaricide activity of the quercetin in Gallus gallus L., 1758 immunocompromised infected by Plasmodium (Bennettinia) juxtanucleare Versiani and Gomes, 1941].

The aim of this study was comparatively to evaluate the malaricide activity of the quercetin to the action of the chloroquine in Gallus gallus experimentally infected for Plasmodium juxtanucleare and immunocompromised. Thirty- four hens had been used, previously infected for P. juxtanucleare and immunocompromised by the administration of 26 mg/kg of metilprednisolon 40mg/ml in the pectoral muscle.
