Opis:
Infections caused by extra-intestinal pathogenic Escherichia coli (ExPEC) are a serious public health problem worldwide. The most troublesome are urinary tract infections, severe neonatal meningitis, serious intraabdominal infections, and more rarely, pneumonia, intravascular-device infections, osteomyelitis, soft-tissue infections or sometimes bacteraemia. These strains are also able cause significant economic losses in animal husbandry. A thorough understanding of ExPEC ecology, reservoirs, chains and dynamics of transmission can greatly contribute to a reduction in the burden of ExPEC-associated disease. The ability of E. coli (including ExPEC) to exist and survive in various ecological niches impedes the precise recognition and indication of transmission routes most important for individual infections cases. Among many identified ExPEC reservoirs, animal companion and animals providing food seem to be important sources of infection for human; however, the real level of risk connected with potential transmission of these bacteria remains unclear. Food is indicated as one of potential ways of transmission. Despite a quite high number of reports, many of the uncertainties are expected to be reliably elucidated. This review presents most important data on the current state of knowledge concerning the potential role of food in ExPEC transmission. The possible consequences of ExPEC infections in human and animals are briefly described.

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:
Botrytis cinerea is the cause of the most common disease in the Galician and Portuguese vineyards. Knowledge of the spore levels in the atmosphere of vineyards is a tool for forecasting models of the concentration of spores in order to adjust the phytosanitary treatments to real risk infection periods. The presented study was conducted in two vineyards, one located in Cenlle (Spain) and other in Amares (Portugal), from 2005-2007. A volumetric trap, model Lanzoni VPPS-2000, was used for the aerobiological study. Phenological observations were conducted on 20 vines of three grape varieties in Cenlle (Treixadura, Godello and Loureira) and in Amares (Trajadura, Loureiro and Pedernã), by using the BBCH scale. The highest total spore concentrations during the grapevine cycle were recorded in 2007 in both locations (Cenlle:16,145 spores; Amares:1,858 spores), and the lowest, in 2005 in Cenlle (1,700 spores) and in Amares (800 spores) in 2006. In Cenlle, the best adjusted model was an ARIMA (0,2,2), including the relative humidity four days earlier, while in Amares there was an ARIMA (1,2,3), considering the relative humidity three days earlier and rainfall two days earlier. The t-test showed no significant difference between observed and predicted data by the model.

Opis:
Sera of 39 farmers, 119 foresters and 32 blood donors were investigated for the presence of antibodies against B. burgdorferi, A. phagocytophilum, B. microti and Bartonella spp. Semi-quantitative indirect immunofluorescence test was used to measure titers of anti-A. phagocytophilum, B. microti and Bartonella spp. IgG. ELISA test was used to measure titers of anti-B. burgdorferi IgM and IgG. B. burgdorferi was the most frequently observed among all the examined pathogens. 27.7% of farmers, 23.1% of forestry workers and 37.5% of control group were infected with Bartonella spp. Anti-A. phagocytophilum and anti-B. microti reactions were observed rarely. Sera of persons with single infection dominated in farmers and forestry workers. Co-infection with 2 pathogens was observed more frequently in forestry workers and farmers than in the control group. Co-infections with 3-4 pathogens were observed only in forestry workers. Among the observed co-infections, the most frequent were: B. burgdorferi with Bartonella spp. and B. burgdorferi with A. phagocytophilum. Moreover, in forestry workers, triple coinfections with B. burgdorferi, Bartonella spp. and A. phagocytophilum and one quadruple coinfection were observed. Persons with occupational risk of tick bites, especially forestry workers, more often have anti-B. burgdorferi antibodies and are more often co-infected with various tick-borne pathogens than the persons from the control group. It seems that more often coinfections in persons with occupational risk of tick bites are a consequence of the higher incidence of infection with B. burgdorferi, as anti-B. microti, A. phagocytophilum and Bartonella spp. antibodies are not more commonly prevalent in persons with occupational risk of tick bites than in healthy volunteers.

Opis:
Objective. This study presents for the first time a case of Hyalomma excavatum hyperparasitism and an analysis of this phenomenon in terms of its potential role in the biology of ticks and epidemiology of tick-borne diseases. Materials and method. Two partially engorged H. excavatum females, one fully engorged female, and 5 males were collected from a naïve rabbit and placed together in a rearing chamber at a temperature of 25 °C and 75% humidity. Results. 3–4 days after tick detachment from the host’s skin, one partially engorged H. excavatum female was observed attached to the idiosoma of the fully engorged conspecific female. Conclusions. This study and observations of other authors confirm that partially engorged ixodid ticks can re-infest the host, and even co-feeding fully engorged ticks in order to collect the blood meal that is indispensable for important physiological processes. However, inefficient feeding of a partially engorged female on another conspecific female may reduce its reproductive performance and disturb the development of eggs and larvae. It seems that parasitism of a tick on another conspecific specimen, when at least one of them is infected by a microorganism, may be a yet poorly explored route of transmission of pathogens or symbionts between the ticks. Initiation of feeding by a hungry or partially engorged tick on a fully engorged specimen is an attempt to obtain food in the drastic conditions of the absence of a target host. Tick hyperparasitism with concurrent pathogen transmission can contribute to the genospecific diversity of pathogens in vectors and hosts.

Opis:
Introduction and objective. Infectious and parasitic diseases transmitted by ticks, such as Lyme diseases, granulocytic anaplasmosis and piroplasmosis, have been frequently reported in Europe, with increasing attention to them as an emerging zoonotic problem. The presented study was performed to assess the distribution and the density of questing ticks in three regional parks of Emilia-Romagna region of Northern Italy, and to seek molecular evidence of potential human pathogens in tick populations. Materials and Methods. In the period April-October 2010, 8,139 questing ticks were collected: 6,734 larvae, 1,344 nymphs and only a few adults – 28 females and 33 males. The abundance of Ixodes ricinus questing ticks was compared among different sampling sites and related to microclimate parameters. 1,544 out of 8,139 ticks were examined for the presence of pathogens: PCR was used to detect piroplasms DNA and Real time Taqman PCR for Anaplasma phagocytophilum and Borrelia burgdorferi s.l. Results. The predominant species was I. ricinus (overall abundance 1,075.9/100 m2); more rarely, Dermacentor marginatus (n = 37 – 0.45%), Scaphixodes frontalis (n = 13 – 0.16%), Hyalomma spp. (n = 6 – 0.07%) and Ixodes acuminatus (n = 3 – 0.04%) were also found. 28 out of 324 (8.6%) samples of ticks were PCR-positive for piroplasm DNA. 11 amplicons of 18S rRNA gene were identical to each other and had 100% identity with Babesia EU1 (Babesia venatorum) using BLAST analysis. Real time Taqman PCR gave positive results for A. phagocytophilum in 23 out of 292 samples (7.9%), and for B. burgdorferi s.l. in 78 out of 292 samples (26.7%). I. ricinus was the only species found positive for pathogens by molecular analysis; 16 tick samples were co-infected with at least 2 pathogens. Discussion. The peak of nymph presence was in May, and the higher prevalence of pathogens occurred in April-June, most often in nymphs; therefore, spring season could represent the higher risk period for the transmission of pathogens. These data could provide guidelines for the preventions of tick-trasmitted diseases in this region.

Opis:
Introduction. The three-host Dermacentor reticulatus tick transmits many pathogens, which are introduced into the host with saliva during feeding. Material and methods. The aim of present study was to analyse the behaviour of males of this species on the host in homogeneous sex groups comprising 15 (group I) and 30 (group II) male specimens and in a mixed group composed of 15 males and 15 females (group III). Results. Although the dynamics of attachment of the males to host skin slightly differed between these three groups, there was no statistically significant difference in the duration of the attachment process. The duration of host attachment of the males in groups I, II, and III at 18 ± 2 °C and 50 ± 2% RH was 2.43 ± 2.46, 7.75 ± 11.85, and 9.07 ± 10.97 days, respectively. After 7–9-day feeding, the male engorgement weight (MEW) was similar, regardless of the size of the group and the presence or absence of females on the host. Tick males ingest a small amount of host blood. The value of MEW in the three groups did not differ statistically from the weight of unengorged specimens. Conclusions. The host feeding behaviour of D. reticulatus males and their effective feeding suggest that they may play a role in transmission of pathogens and non-pathogenic microorganisms with tick saliva during blood meal ingestion. Clinical and laboratory diagnostics of human and animal tick-borne diseases as well as epidemiological studies should consider the possibility of pathogen transmission by males of metastriata ticks, which feed on the host for several days.

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
