Blood parasites in some birds from eastern plains of Colombia.

Prevalence of blood parasites in Tyrannidae (flycatchers) in the Eastern plains of Colombia.

Blood samples from 159 birds of the New-world family Tyrannidae (the flycatchers) from the eastern plains of Colombia, were examined for haematozoa parasites, in 1999-2000. Haematozoa were detected in six of 20 species. The overall prevalence was 10.1%. The most common parasites detected were microfilariae, followed by Trypanosoma and Plasmodium. The highest prevalence (9.6%) was found in the O...

RESISTANCE OF PLASMODIUM FALCIPARUM TO CHLOROQUINE IN SOUTH EASTERN IRAN

In vivo and in vitro assessments of the response of P. falciparum to chloroquine using WHO standard kits and techniques were carried out in I ran Shahr, Sistan and Baluchestan province of Iran in 1985. In the in vivo assessment, 24 malaria patients treated with chloroquine (25mg/kg over three days) were followed up for one to four weeks. The mean parasite clearance time was 4.3 days and in...

Ectoparasitism shortens the breeding season in a colonial bird

When blood-feeding parasites increase seasonally, their deleterious effects may prevent some host species, especially those living in large groups where parasites are numerous, from reproducing later in the summer. Yet the role of parasites in regulating the length of a host's breeding season-and thus the host's opportunity for multiple brooding-has not been systematically investigated. The hig...

Zoonotic helminthic parasites in abdominal cavity of pike- perch, Sander lucioperca, from southeastern part of the Caspian Sea

Some parasites can be transferred from fish to human via eating of contaminated meat and make serious problems in consumers. In the present study zoonotic parasites of abdominal cavity in pike-perch, Sander lucioperca, in south eastern part of the Caspian Sea have been surveyed. In this regard, 30 fish were caught by purse seine net and abdominal cavity, digestive tract and other organs (kidney...
