Trypanosomosis is a disease caused by a flagellate protozoan known as Trypanosoma evansi, transmitted by hematophagous insects. It parasites showed a large diversity of mammalian hosts. Dogs may show clinical changes such as weight loss, progressive weakness, anorexia, anemia, intermittent fever, conjunctivitis, swelling of limbs and increased of superficial lymph nodes. Treatment of trypanosom...

During the past years, species specific PCR's for identifying the different taxa within the Trypanozoon subgenus have been developed by our laboratory. For the detection of the two human pathogenic trypanosomes, PCR-SRA for T. b. rhodesiense (Radwanska et al., 2002) and PCR-TgsGP gene for T. b. gambiense (Radwanska et al., 2002) exist now. For animal trypanosomiasis, a T. evansi specific PCR ba...

Antifilarial activity of 5/6/7/8-mono- or disubstituted 1 H/1-phenyl-9H-pyrido[3,4-b]indoles (I) has been described. The 1,6- and 8-substituted 9H-pyrido[3,4-b]indoles (I) elicited interesting filaricidal activity against Litomosoides carinii and Acanthocheilonema viteae in rodent hosts.

The sandfly Lutzomyia evansi from a focus of visceral leishmaniasis in northern Columbia was reared and maintained under laboratory conditions for five generations. The average time for total development was 41.9 days (range = 35.1-49.6) at 25 degrees C and 89-95% of relative humidity. The mean number of eggs laid was lower in laboratory bred females either in pots (13.2 eggs/female) or vials (...

Existen hemoparásitos (protozoarios y bacterianos) intracelulares que parasitan diversas células sanguíneas. También, en forma extracelular, como el protozoario Trypanosoma evansi, cual ocasiona enfermedades animales humanos. En zonas tropicales, Costa Rica, la transmisión de se favorece por abundancia artrópodos hematófagos actúan vectores biológicos (por ejemplo, las garrapatas son los protoz...

Definition of the disease: Trypanosoma evansi causes a disease known as Trypanosomosis1 5 (‘surra’). It affects a number of domesticated animals species in Asia, Africa and Central and South 6 America. The principal host species affected varies geographically, but buffalo, cattle, camels and 7 horses are particularly affected, although other animals, including wildlife, are also susceptible. It...

Background: Trypanosoma evansi is a fl agellate which belongs to the salivate section, commonly observed parasitizing blood of equines, ruminants, pigs, dogs and wild animals in different regions of the world. It causes many losses to farmers due to death of animals and drug spending in endemic areas. The treatment of this disease in Brazil is only performed with diminazene aceturate; however i...

Genetic variation of microsatellite loci is a widely used method for the analysis of population genetic structure of microorganisms. We have investigated genetic variation at 15 microsatellite loci of T. evansi isolated from camels in Sudan and Kenya to evaluate the genetic information partitioned within and between individuals and between sites. We detected a strong signal of isolation by dist...
