SummaryThe proportion of blood meals taken on humans which are infectious to mosquitoes in the Madang area, Papua New Guinea was estimated by two methods. In the first, laboratory rearedAnopheles farautiwere fed on individuals of all ages at village surveys. The results showed that 3·8% of people were infectious and that the mean percentage of mosquitoes which became infected by feeding on these people was 37·9%. From the average proportion of mosquitoes infected, the probability that a mosquito feeding on a human would pick up infection was 0·013±0·005. In the second approach mosquitoes were

Introduction. Global climate changes affect the habitats of insects, including mosquitoes, which are carriers of dangerous natural focal infections. When mosquitos develop new territories, they create a potential threat to people who find themselves in these areas. In the Krasnodar Region, a stable population of Ae. albopictus mosquitoes was formed in the 21st century. These mosquitoes are carriers of many viral pyrrhoid-focal infections, such as Dengue, Chikungunya, Zika fever and Yellow fever. Estimations of biological, epidemiological and cultural data can help to answer the question of the

SUMMARYThe vector competences of 6 geographic strains of Aedes polynesiensis for Wuchereria bancrofti were studied using two types of experimental infections. Experimental infection of laboratory-bred mosquitoes fed on the carriers' forearms with different levels of microfilaraemia showed that microfilariae (mf) uptake was directly proportional to the carrier's mf density and, as mf densities decreased, concentration capacity of Ae. polynesiensis increased. It was also shown that infection has an important effect on mosquito mortality, and that the mortality rate differed among mosquito strain

Summary. Introduction. Warming in Ukraine leads to the displacement of warm zones to colder ones, and at the same time, to the removal of colonization zones of many insectivores, which are carriers of rare diseases in Ukraine. Materials and methods. Clinical observation of Dirophilaria immitis of the pleural cavity is given. The patient was treated for «pneumonia» by a family doctor and a district therapist for two months. Only after consultation with a thoracic phthisiosurgeon was diagnosed with chronic pleural empyema and performed pleurectomy. A living string-like body was found in th

Malaria is caused by the Plasmodium parasite, which is transmitted by female Anopheles mosquitoes. There are five Plasmodium species that cause disease in humans; however, the most important species in terms of disease burden are Plasmodium falciparum, which is prevalent in sub-Saharan Africa, and Plasmodium vivax, which is more common in Asia and South America. There were an estimated 219 million malaria cases and 435,000 deaths worldwide due to malaria in 2017; Sub-Saharan Africa carries a disproportionately high share of the malaria burden, with 92% of cases and 93% of malaria deaths in 201

Most blood parasitoses are transmitted by means of carriers - ticks or insects, which bodies undergo certain development stages or transmission is carried out mechanically. Dirofilariasis is a zoonotic disease of animals and humans carried by mosquitoes. The reasons for dirofilariasis spread are the unrestricted movement of animals from one region to another. To diagnose dirofilariasis, a microscopy method of a fresh blood drop was used. Diagnosis for babesiosis in animals was made based on clinical traits and results of microscopic examination of peripheral blood smears stained according to R

SUMMARYThe effects of sex, age of the human host, patency of asexual and sexual stages and seasonality on infectiousness of Plasmodium falciparum to mosquitoes were investigated in a rural village in southern Tanzania between 1992 and 1994. Villagers from randomized subgroups of households were surveyed for malaria parasites. Gametocyte and trophozoite prevalences were age dependent and fluctuated without any clear pattern of seasonality. A sample of 107 participants, selected to include an excess of gametocyte carriers, slept under bednets with holes cut into the sides for 3 weeks. A total of

The article presents the current state of the problem of dirofilariasis. Helminth infection caused by nematodes of the genus Dirofilaria is mainly a disease of carnivores from the canine and feline families. Humans are considered occasional hosts in which Dirofilaria spp., more commonly D. repens, rarely reach sexual maturity. The climatic conditions of the territory are one of the determining factors for the spread of vector-borne diseases. Due to the fact that in recent years there has been a tendency to increase average temperatures everywhere, these changes lead to a shift and expansion of
