Opis:
The Yucatan Peninsula of Mexico is endemic with Chagas disease. The main vector responsible for Trypanosoma cruzi transmission is Triatoma dimidiata which is abundant in domestic, peridomestic and sylvan cycles. The abundance of vectors favours T. cruzi transmission and is a high risk for developing chronic chagasic cardiomyopathy (CCC). In the past 10 years, little information was available on parasite seroprevalence and the prevalence of CCC in the Yucatan Peninsula. In the present work, we studied two Mayan communities with a high abundance of T. dimidiata and a random serial sample of 233 patients with an altered electrocardiogram or cardiac failure admitted to the Regional Hospital. A homemade enzyme-linked immunosorbent assay and indirect immunofluorescence standardized techniques were used to detect anti-T. cruzi IgG. In addition, Mayan volunteers were monitored by electrocardiography. In the Mayan communities, 4.8% (3/63) subjects were positive for T. cruzi antibodies none of them presented electrocardiographic alterations, however in seronegative subjects were detected right or left ventricle hypertrophy in 25% (16/63). A remarkable finding was that 90% of the Mayan population recognized the vector and 65% of them had experienced contact with triatomines bites. At the Regional Hospital 0.42% (1/233) were positive for T. cruzi antibodies showing compatible diagnosis with CCC; the most frequent pathology in this population was hypertension in 65% (151/233) and the less frequent was dilated myocardiopathy 6% (14/233). In conclusion, the prevalence of T. cruzi infection and CCC can be considered low in Yucatan, Mexico.

Opis:
In man, as well as in many species of vertebrates there exist several populations of Giardia duodenalis group which, though morphologically indistinguishable, show different level of heterogenicity in several characteristics, a. o. in surface antigens, isoenzyme make-up, RFLP, invasiveness for different hosts or pattern of experimental infection. Also the clinical observations in man distinctly suggested that G. intestinalis comprises several different populations. In the course of giardiosis apparent variability in clinical manifestations can be observed. In many patients the infection is symptomless and resolves spontaneously and in some others – variable intensity of symptoms is observed. Most likely both the parasit's characteristics and the host's feature will determine the clinical character of infection. It is well known that in some cases it is the host that responsible for the symptoms of the infection. Thus, for instance, clinical giardiosis links with immunodeficiency, malnutrition or young age. There are also evidences that some Giardia isolates have enhanced potency to provoke the disease of the host. It is considered that the variable pattern of the infection may be related to three different factors in host-parasite relationship: extra- and intrapopulation variability of Giardia isolates, the microenvironmental factors of the host's intestine, and the variable immune response of the host. The author describes data on the two first factors.

Opis:
In spite of the enormous achievements of medical and biological sciences, parasites still constitute important medical and veterinary problem. One of the main obstacles in the treatment and eradication of human and animals parasitic diseases is drug resistance of parasites. This phenomenon has more and more frequently been described both in medical and veterinary practice. The application of numerous molecular biology techniques in modern parasitological laboratories have enabled the investigations of parasites at the DNA level. The results of these studies have revolutionised our knowledge and made possible the recognition of not only the reasons and extent of genetic differentiation of parasites but also the recognition of genetic and molecular mechamisms of drug resistance. The results of many studies showed interspecific, interpopulational, and even intrapopulational heterogeneity of parasites in their sensitivity to antiparasitic drugs. Moreover, it has been found that in various parasites there often exist different molecular bases of the drug resistance. The review concerns different molecular mechanisms of drug resistance in selected parasite taxa (Schistosoma spp., Haemonchus contortus, Leishmania spp., Plasmodium falciparum, Entamoeba histolytica).
