Opis:
Ticks are known as vectors of a wide range of pathogens of medical and veterinary importance; some of them of zoonotic concern constitute a hazard for the emergence of tick-borne diseases shared between humans and domestic animals and becoming a part of the ‘One Health’ concept. Canine and feline tick-borne diseases have emerged in recent years, performing an extensive geographic distribution and enlarged global prevalence. The present review focuses on the recent epidemiological studies on the emergence of tick-borne bacterial pathogens in dogs and cats, and the discussion whether pet ownership increases the risk of tick-borne diseases. A lot of data provide confirmation that dogs and cats themselves may substantially contribute to the circulation of the ticks and tick-borne bacterial pathogens in the environment. Molecular diagnostics of tick-borne pathogens infections generates a lot of problems like the choice of molecular methods and molecular markers for the detection of bacterial genomic DNA, but play an important role in the diagnosis of infections. The study provides some insight into molecular diagnostic techniques and new potentially recognized bacterial pathogens of this group. Protecting human and companion animal health from vector-borne infections requires controlling vector populations, containing development of novel, practicable strategies that will limit vectors and transmission of vectorborne disease pathogens.

Opis:
Toxoplasmosis is globally distributed, water- and food borne zoonosis caused by the single protozoan Toxoplasma gondii and probably one-third of the world’s human population is infected with this pathogen. Domestic and wild felids are definitive hosts of this pathogen and intermediate hosts for great variety of other homoeothermic animals. Human as other of the intermediate hosts may become infected in the main route of infection; it is the ingestion of parasite oocysts in contaminated water or soil and undercooked meat. However, the mechanism which this parasite uses to so large spread is not fully understood, because oral transmission does not explain the common event of this parasite in a variety of hosts, such as herbivorous animals or rodents and birds, as well as routes of spread to domestic hosts. Such a wide circle of hosts suggests a possibility of other paths of transmission and a role of ticks, the bloodseeking arthropods was considered in the transmission of T. gondii.

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.

Opis:
Attempts were made to identify the causative orgamsm of Lyme disease in Szczecin from tick Ixodes ricinus as a vector. Ticks were collected in 1997 year in forest areas of Szczecin, from localites associated with numerous attendance of people. The method used in this study was the polymerase chain reaction (PCR) on the flagellin structural gene fla of Borrelia burgdorferi sensu stricto. The flagellin PCR primer set reaction was conservative for B. burgdorferi sensu stricto, B. afzelii and B. garinii. The overall prevalence of B. burgdorferi sensu lato, in tick population studied was 8.8%. The female, nymphs and larves of Ixodes ricinus were infected almost just the some - about 10%, when the male 2.5% only.

Opis:
Borrelia burgdorferi sensu lato (s. I.), the etiological agent of Lyme diesease, is transmitted by the bite of Ixodes ricinus. During May and September 1999, field surveys on Lyme disease spirochetes were conducted in three locations of a region of north-west Poland, known as recreational districts visited by many people. The ticks Ixodes ricinus were collected in natural habitats by dragging a flanel cloth over the vegetation. Sex and developmental stage of each tick were determined. Based on a polymerase chain reaction test with primers that recognize a chromosomal gene of all strains, out of the total 1414 specimens collected, 126 (8.9%) were found to be infected. the species B. burgdorferi s. 1. comprises at least three pathogenic genomospecies, B. burgdorferi sensu stricto (s. s.), Borrelia garinii, and Borerelia afzelii, witch could be distinguished in nested-PCR tests with species-specific primers. B. burgdorferi s. s. was most prevalent (96% of infected ticks), followed by B. garinii (1.3%), and B. afzelii. was not found. Of the infected ticks, over the 99% were infected with a single species; one specimens was infected with two species. For 4 ticks, the infecting species could not be identied. The difference in rates of prevalence was observed among the tree locations (17%-5.3%-3.2%).

Opis:
The occurrence of Ixodes ricinus in the selected recreative areas in the province of Szczecin. Part III. Within the last years, the incidences of diseascs transmitted by Ixodes ricinus tick have rapidly increased. We estimated the occurrence of Ixodes ricinus in the popuJlr recreation urban areas in Szczecin and in the Province of Szczecin. The study was carried out in 1999, with two samples at each site, and were compared with data of 1998. The temperature and humidity of air were measured. The most ticks were found in the range of 70-80% relative humidity of air. Among 3.198 specimens collected 59.5% were nymphs, 19.0% larvae, 11.1 % females and 10.4% males. The nymphs were the most frequent in spring and in autumn, while the larvae were most frequent in autumn (26.2%) then in spring (11.9%).

Opis:
Human babesiosis is caused predominantly by B. microti and B. divergens, a protozooan parasites of red blood cells. Both are transmitted by Ixodes ricinus ticks, also the primary vector of Lyme disease. Clinical manifestation varied widety from asymptomatic infection to a serve rapidly fatal disease. The diagnosis of babesiosis include examination of stained blood smers, serological evaluation indirect antibody tests and PCR. With the evolution PCR - based techniques, the diagnosis and monitoring of babesial infections became more sensitive and reliable.

Opis:
Trophozoites of Balantidium coli were isolated from the pig's caecum and cultivated in vitro. Pigs were divided into two groups: one with the acute balantidiosis and the second - with the asymptomatic balantidiosis. In the first case the biotic potential of protozoans turned out to be higher (the most intensive divisions occurred 24 hours after the second passage). Protozoans isolated from pigs with the asymptomatic balantidiosis had lower biotic potential (the most intensive divisions occurred 24 hours after the third passage). This fact indicates the differentiation of the investigated populations of B. coli.

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.
