    Opis:
    Mycologic investigations were carried out in subjects suffering from upper respiratory tract ailments. The material for assessment was collected from various ontocenoses. Species of fungal strains were determined by means of the morphological and biochemical analyses. Special attention was paid to the frequency of fungi occurring in multiple foci of the same system. In patients presented with ailments of the upper respiratory tract the presence of fungi, predominantly species of Candida genus was detected in different ontocenoses. In 1/4 of cases the fungi were found in 2 or 3 foci, which can induce systemic transmission, interfere with treatment and result in recurrent infections.

    Ehrlichia
    Opis:
    Ehrlichias occur in ticks in the cells of their haemolymph-hematocytes. They enter the vertebrate host organism with the saliva of the tick, during a blood meal. Humans can also be the hosts for this pathogen. Two pathogens cause a humane disease-monocytic ehrlichiasis (E. chaffensis) or granulocytic ehrlichiasis (HGE factor). The above disease units are difficult to diagnose because of their non-specific symptoms. A preliminary study has been conducted on the prevalence of the HGE factor in the ticks, Ixodes ricinus in the recreational areas of the West-Pomeranian Province. All forms of I. ricinus were collected from 3 sites. All the sites are known to be frequented by hikers and gatherers of forest mushrooms and berries. The site selection involved also careful consideration of the tree- and underbrush type. The ticks were collected twice a year in spring (May/June) and in autumn (August\September), which was associated with the biological activity of the collected acarines. A total of 1159 Ixodes ricinus ticks were collected, in this number 172 females, 167 males, 597 nymphs, and 223 larvae. Using the PCR technique, the 16SrRNA-gene fragment was amplified using primers specific for the HGE factor: EHR 790 and EHR 521. The studied population contained 3.7% infected females in spring and 2.7% in autumn, 0.68% infected males in spring, no infected in autumn. The nymphs were infected in spring (2.17%) and in autumn too (0.73%), but the larvae were not infected in both seasons. Analysing the above-mentioned results it can be concluded that the decisive majority of the individuals transmitting the HGE factor are the adult forms.The present study was only a preliminary one. In the future much more sites will be monitored, in the recreational areas of both the city of Szczecin and the entire province.

    Opis:
    Babesia and Theileria are the tick-borne parasites belonging to the order Piroplasmida. Both of them cause a severe disease with symptoms of hemolytic anemia. The main etiological factors of canine piroplasmosis are protozoa Babesia. There are two species of this pathogen infective for dogs: Babesia canis and Babesia gibsoni. Based on the results of molecular biology techniques it is possible to distinguish them as well as many subspecies or strains. It is known since quite some time that there are substantial differences in vector specificity, cross-immunity and pathogenicity between isolates of this species. Also the results of molecular analysis of these protozoa indicate that their genetic structure is diversified. On the basis of analysis of Babesia DNA sequences, the new variants of protozoa in dogs were detected. It is possible that, these new variants of Babesia are characterized by high virulence for dogs and resistance to drugs used in babesiosis therapy.

    Opis:
    This article presents the current state of our knowledge on babesiosis (piroplasmosis), one of the dangerous, invasive disease of humans and animals, transmitted by ticks. It is included among emerging diseases because its spread and significance have increased in recent years. This sickness is caused by intraerythrocytic parasites belonging to the Babesia species and it is a well−known zoonosis occurring in animals; as a human disease it was unknown almost till the first half of the last century. The intensified migration of human population and human interference in a forest biotope caused that number of recognized cases has grown considerably in recent years. Piroplasmosis in dogs is widely spread all over the world and it is caused by several Babesia species. The principal etiological factor of babesiosis in dogs is B. canis, which turned out to be a collective species represented by three subspecies for which the vectors are three different species of ticks. Their geographical extent indicates the endemic areas for this often fatal disease. A technique, the most often applied in the detection of Babesia is a full blood smear stained with Giemsa or Wright method. However, the estimation of the specimen depends to a large extent on the experience of the diagnostician. The immunological and serological methods are characterized with a high specificity and sensitivity but there are patients in which the false negative results have been obtained. Therefore, the traditional methods have been complemented or even ousted by the molecular methods, in which polymerase chain reaction (PCR) brings the biggest profits. However, the standardization of this technique still remains under elaboration. The usefulness of the PCR protocol has been tested with different molecular destinations from which sequences of genes encoding rRNA for small ribosomal subunit are taken into consideration. Within ribosome, the evolutionally conservative areas can be distinguished, i.e. having the nucleotide sequences similar to the majority or all Babesia species and to others closely related to them. Such construction of gene enables designing of starters complementary to conservative sites to PCR, detecting a large group of related organisms. Another molecular marker allowing on the accurate identification of Babesia is gene encoding the ß-tubuline protein. There are two introns within this gene, from which the first one shows a big variability with regard to the length as well as to the nucleotide sequence, therefore, the PCR products show a diverse length depending on the Babesia species. But these differences are too small for some species and, confirming methods that extend time of diagnostics are essential. The other genes which sequences can be used as molecular aim to the detection of DNA and Babesia species diversification are genes encoding the Heat Shock Proteins HSP 70. However, the gene hsp 70 shows a big conservatism of the nucleotide sequence even between the non related organisms; therefore, this method, based on the amplification of whole genome or its fragments, applies mainly in analysis of molecular phylogenetic.
