    Opis:
    Introduction and objective. It is easier and non-invasive to obtain faecal samples compared with blood samples. Molecular techniques may enable detection of parasites even in tiny amounts of blood-containing faeces. We aimed to compare the sensitivity of detection of three Babesia species and Hepatozoon canis in blood and faecal samples, including samples derived from naturally infected hosts. Materials and method. Three groups were involved: 1) Nine BALB/c mice infected with Babesia microti sampled during acute (n=3), post-acute (n=3) and chronic phases of infection (n=3); 2) Eight dogs with symptoms of babesiosis; 3) Six red foxes infected with B. vulpes, one fox infected with B. canis, four foxes infected with H. canis. Genomic DNA was extracted from blood and faeces by use of commercial kits and amplified with genus-specific primers in one-step or nested PCR reactions. Selected PCR products were sequenced. Results. No positive results for faecal samples were obtained from H. canis-positive foxes in contrast to Babesia spp. infections. Positive results from PCRs were obtained for all BALB/c mice (100%), five dogs (62.5%) and four of seven foxes (57.1%). Successful sequencing was obtained for six selected murine samples (B. microti), four canine samples (B. canis) and for one fox sample (B. vulpes). The success of B. microti detection in murine faecal samples from acute, post-acute and chronic phases was identical (100%). Conclusions. Detectability of Babesia spp. infections was lower in naturally infected dogs and foxes, compared to experimentally infected mice. Detection of DNA in faecal samples can be useful in the detection of Babesia infection in populations from which blood samples are hard to obtain, but due regard must be given to the possibility that prevalence of infection may be severely underestimated.

    transovarial transmission
    Opis:
    The Dermacentor reticulatus tick is a main vector of Babesia canis in Europe. The risk of canine babesiosis is unpredictable, due to significant differences in the prevalence of B. canis between ticks originating from closely situated regions. This phenomenon may be explained by vertical transmission of the pathogen in a vector population. Thus, molecular techniques were applied to investigate the occurrence of transovarial transmission in D. reticulatus ticks. DNA of B. canis was detected in 20.7% (6/29) of engorged female ticks collected from dogs, in every pool of eggs laid by positive females (100%, 6/6) and in larvae hatched from these eggs. In the pools of eggs collected from two positive females (2/6; 33.3%), no larvae hatched and no embryos were observed inside the eggs. Conclusions. Transovarial transmission of B. canis can be an important mechanism supporting maintenance of the pathogen in the environment without the presence of a reservoir vertebrate host. However, the efficiency of transovarial transmission in the maintenance of B. canis in natural conditions requires further field research.

    Opis:
    Wprowadzenie i cel pracy. Kleszcze są zaliczane do obligatoryjnych ektopasożytów kręgowców lądowych, w tym również i człowieka. Stanowią rezerwuar, niekiedy wektor wielu drobnoustrojów chorobotwórczych (bakterii, wirusów i pierwotniaków) zagrażających zdrowiu zwierząt i ludzi. Głównym celem pracy była próba oceny, czy powszechnie występujące w Polsce kleszcze z gatunku Ixodes ricinus i Dermacentor reticulatus mogą stanowić potencjalny wektor i rezerwuar dla pierwotniaków: Babesia i Theileria, oraz Toxoplasma gondii, a tym samym odgrywać rolę w krążeniu tych patogenów w przyrodzie. Skrócony opis stanu wiedzy. Do grupy pierwotniaków występujących w kleszczach należą rodzaje Theileria spp., Babesia spp., i jak stwierdzono w ostatnich badaniach – Toxoplasma gondii. Rodzaje Theileria i Babesia stanowią duże zagrożenie głównie dla zwierząt, powodując m.in. gorączkę wschodniego wybrzeża, tropikalną tejleriozę, babeszjozę. Z kolei Toxoplasma gondii to pierwotniak szczególnie niebezpieczny dla kobiet w ciąży, który może wywoływać trwałe i nieodwracalne wady płodu. Dotychczasowe badania potwierdzają obecność tych pierwotniaków u niektórych gatunków kleszczy, jak również możliwość współwystępowania niektórych z nich w jednym osobniku. Podsumowanie. Z punktu widzenia zdrowia publicznego, badania dotyczące potencjalnej roli kleszczy w transmisji pasożytniczych pierwotniaków mogą przyczynić się do oceny realnego zagrożenia nabycia infekcji w przypadku pokłucia przez kleszcze. Szczególne znaczenie dla kobiet ciężarnych miałyby wyniki dotyczące roli kleszczy jako alternatywnej drogi w transmisji Toxoplasma gondii – czynnika etiologicznego toksoplazmozy.
    Introduction and objective. Ticks are classified into obligatory eco-parasites of terrestrial vertebrates, including humans. They constitute a reservoir, sometimes a vector of many pathological microorganisms (bacteria, viruses and protozoa) threatening the health of humans and animals. The primary objective of the study was an attempt to evaluate whether ticks of the species Ixodes ricinus and Dermacentor reticulatus, commonly occurring in Poland, may constitute a potential vector and reservoir for the protozoa: Babesia, Theileria, and Toxoplasma gondii, and at the same time, play a role in the circulation of these pathogens in nature. Brief description of the state of knowledge. The genera Theileria spp., Babesia spp, and as has been found in recent years, Toxoplasma gondii belong to the group of protozoa occurring in ticks. The genera Theileria and Babesia create a great risk, mainly for animals, causing, among others, east coast fever, tropical theileriosis and babesiosis. In the case of Toxoplasma gondii, this protozoan is especially dangerous for pregnant women, and may cause permanent and irreversible foetal defects. Studies to-date confirm the presence of these protozoa in some species of ticks, as well as the possibility of co-occurrence of some of them in one individual tick. Summing up. From the aspect of public health, studies concerning the potential role of ticks in the transmission of parasitic protozoa may contribute to the assessment of the actual risk of infection in the case of tick bites. The results concerning the role of ticks as an alternative route of transmission of T. gondii – the etiologic factor of toxoplasmosis, would be of a special importance for pregnant women.

    Opis:
    In this study we report the usefulness of nested PCR for screening of the persistent B. microti infections in rodent hosts. Female BALB/c mice were inoculated with 100 μl of donor blood infected with B. microti. Infections were detected using microscopic examination of Giemsa-stained blood smears. To determine whether B. microti DNA was present in blood and/or spleen tissue, nested PCR was performed targeting a specifi c fragment of the gene encoding the 18S rRNA. Blood was sampled every 10 days post-infection (dpi) until day 30, after which mice were sampled every 30 days until the end of experiment at 360 dpi. The most extensive parasitaemia (39% of infected erythrocytes) was observed at 10 dpi. Between 20-60 dpi, less then 1% of infected erythrocytes were detected in blood smears, and from 90 dpi onwards, infected erythrocytes were no longer observed. B. microti DNA was successfully amplifi ed from the blood of mice from 10 dpi until 180 dpi, as well as from spleens of infected mice at 10 and 20 dpi. The presented results show that nested PCR is the method of choice for monitoring infections of B. microti in the blood of rodent hosts, and could therefore be a tool for environmental monitoring of naturally infected rodents which are the predominant source of infection for tick vectors.

    Opis:
    Occurrence of co-infections with various pathogens in ixodid ticks creates a risk of increased severity of tick-borne diseases in humans and animals exposed to bite of the ticks carrying multiple pathogens. Accordingly, co-infections in ticks were subject of numerous analyses, but almost exclusively with regard to Ixodes ricinus complex whereas potential tick vectors belonging to other genera were much less studied. Taking into consideration the role of Dermacentor reticulatus in the transmission of various pathogens, we carried out for the first time the comprehensive statistical analysis of co-infections occurring in this tick species. An attempt was made to determine the significance of the associations between 6 different pathogens occurring in D. reticulatus (Tick-borne encephalitis virus = TBEV, Anaplasma phagocytophilum, Rickettsia raoultii, Borrelia burgdorferi s. l., Babesia spp., Toxoplasma gondii), using 2 statistical methods: determination of Odds Ratios (ORs) and the Fisher’s exact test. 634 questing Dermacentor reticulatus ticks (370 females and 264 males) were collected in 2011–2013 by flagging the lower vegetation in 3 localities in the area of Łęczyńsko-Włodawskie Lakeland, situated in the Lublin region of eastern Poland. The presence of individual pathogens was detected by PCR. Ticks were infected most often with Rickettsia raoultii (43.8%), less with TBEV (8.5%), and much less with Babesia spp., Toxoplasma gondii, Borrelia burgdorferi s.l., and Anaplasma phagocytophilum (2.5%, 2.1%, 1.6% and 1.1%, respectively). The locality-dependent variability proved to be significant for TBEV (c2=11.063; P=0.004) and Toxoplasma gondii (c2=11.298; P=0.0035), but not for other pathogens. Two hundred seventy (42.6%) of the examined ticks were infected only with a single pathogen, and 54 (8.5%) showed the presence of dual co-infections, each with 2 pathogens. The most common were dual infections with participation of Rickettsia raoultii (7.41%); next, those with participation of the TBEV (5.21%), Toxoplasma gondii (1.58%), Borrelia burgdorferi s.l. (1.26%), Anaplasma phagocytophilum (0.95%), and Babesia spp. (0.63%). On the total number of 15 possible associations, in 9 cases co-infections occurred whereas in 6 cases they were not detected. The most noteworthy were positive co-infections with the participation of TBEV, which proved to be weakly significant (0.05

    Opis:
    Introduction. Ticks (Acari: Ixodida) are vectors and/or reservoirs of many pathogens, i.e. Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum and Babesia microti. These pathogens are ethiological agents of such diseases as Lyme borreliosis, human granulocytic anaplasmosis and human babesiosis. Objective. The aim of the study was to evaluate the role of the Ixodes ricinus in the transmission of Borrelia burgdorferi sensu lato, Borrelia afzelii, Borrelia garinii, Borrelia burgdorferi sensu stricto, Anaplasma phagocytophilum and Babesia microti in Opolskie Province in Poland. Materials and method. DNA from 222 ticks was isolated by the ammonia method. The pair of primers specific to the flagelline gene was used to detect of B. burgdorferi s. l. To detect of genospecies of this spirochete, three pairs of internal primers were used. In turn, two pairs of primers specific to the 16S rDNA gene and the 18S rRNA were used, respectively, for the detection of A. phagocytophilum and B. microti. Borrelia burgdorferi s. l., A. phagocytophilum, and B. microti were detected in 4.5%, 2.7% and 5.4% of examined ticks, respectively. Results and conclusions. Of the ten ticks infected with B. burgdorferi s. l., B. afzelii was found in seven, undefinied genospecies in two, and mixed infection with B. afzelii and B. burgdorferi s. s. in one. The study demonstrated the potential risk of exposure of humans and animals to infections of B. burgdorferi s. l., A. phagocytophilum and B. microti in the examined area of Poland.
