“…On the one hand, educating local residents about the vastly greater risk of encountering an infected nymphal tick in forest compared to field or forest-field edge might stimulate the use of self-protective behaviors, including avoidance of forest, use of protective clothing, application of repellent, and conduct of ''tick checks,'' particularly when forests are visited. On the other hand, these landscapes would seem to be ideal venues for the application of either biological or judicious chemical control measures aimed at ticks (Ostfeld et al, 2006). Biological and chemical control agents will likely be considerably more effective if applied to forest interiors than to fields or forest-field edges, where ticks are relatively scarce.…”

More than 19,000 human cases of Lyme disease (LD) are reported each year in the United States.Lyme disease cases occur when humans are exposed to the bacterium Borrelia burgdorferi through the bite of an infected ixodid tick. The probability of human exposure to infected ticks results from a combination of human behaviors and entomological risk. Human behaviors include use of tick habitats, use of protective clothing, and grooming for tick removal. Entomological risks include the density of ticks in a habitat and the proportion of these that are infected with B. burgdorferi. Recent studies have suggested that humans are at higher risk of exposure to B. burgdorferi near edges between forests and herbaceous communities, including lawns and old fields, but whether this increased risk is a function of human behaviors, entomological risk, or both, is unknown. We assessed entomological risk across forest-old field edges in Dutchess County, NY. Densities of ticks and of infected ticks were considerably higher within forests than at forest-field edges, and were lowest within fields. Thus, edges between forests and fields do not pose a higher entomological risk than do the forests themselves, although risk at the edge is higher than in herbaceous habitat. Landscapes with abundant edges between forested and herbaceous habitat, and roughly even proportions of both, might attract both heavy human use and pose moderately high entomological risk, and thus could be targeted for mitigation. We suggest that determining appropriate methods for reducing human exposure to LD requires differentiating entomological risk from human behaviors.

“…Safety risks for humans and domestic animals to this strategy include environmental contamination (Pell et al 2001), impacts on non-target organisms (Schulze et al 2001), human health problems due to chemical residues in food products (Ostfeld et al 2006), and the development of resistance in ticks (Graf et al 2004). More environmental-friendly alternatives such as biological control based on the use entomopathogenic fungi are being developed (Feng et al 2004;Faria and Wraight 2007;Maniania et al 2007;Nchu et al 2010).…”

Compatibility between Calpurnia aurea leaf extract, attraction aggregation, and attachment pheromone and entomopathogenic fungus Metarhizium anisopliae on viability, growth, and virulence of the pathogen

et al. 2011

Metarhizium anisopliae sensu stricto (ss) (Metsch.) Sorok. isolate ICIPE 07 is being developed as biopesticide for the control of ticks. In addition, leaf extracts of Calpurnia aurea Benth, and the attraction aggregation and attachment pheromone (AAAP) are being used as ticks' attractant. The three agents are being considered for use in combination in an autodissemination approach, whereby ticks that are attracted to semiochemicals are infected with the inoculum. Experiments were therefore conducted to evaluate in vitro the compatibility between C. aurea, AAAP, and the M. anisopliae on vegetative growth, conidial production, and spore viability. Calpurnia aurea leaf extract was compatible with the fungus at all the concentrations tested, whereas AAAP inhibited all the fungal growth parameters. The virulence of M. anisopliae formulated in emulsifiable extracts of C. aurea was also tested against different developmental stages of Rhipicephalus appendiculatus in laboratory bioassays. No significant differences in virulence were observed between M. anisopliae applied alone and M. anisopliae formulated in different concentrations of C. aurea leaf extracts. These results suggest that C. aurea leaf extracts is compatible with M. anisopliae and could be mixed together for "spot-spray" treatments as lowcost and environmental-friendly technology to control ticks in grazing field, while AAAP should be used separately.

“…Również stwierdzenie przez pacjenta, że został ukąszony przez kleszcza, może być trudne. Wynika to głównie z obecności w ślinie kleszcza substancji o działaniu przeciwbólowym, wskutek czego moment ugryzienia może pozostać niezauważo-ny [20]. Należy jednak pamiętać, że do rozpoznania boreliozy z Lyme nie jest bezwzględnie wymagane podanie przez pacjenta podczas wywiadu lekarskiego informacji o ukąszeniu.…”

StreszczenieW artykule przedstawiono zagadnienia dotyczące diagnostyki chorób odkleszczowych w Polsce, które stanowią obecnie jedną z grup chorób zawodowych o najszerszym zasięgu na terenie naszego kraju. Problem ten jest aktualny z uwagi na stale rosną-cą liczbę przypadków zachorowań na choroby odkleszczowe (m.in. boreliozę z Lyme, odkleszczowe zapalenie mózgu, tularemię, gorączkę Q, ludzką anaplazmozę granulocytarną, babeszjozę). Odzwierciedlają ten stan zwłaszcza ostatnie meldunki epidemiologiczne Narodowego Instytutu Zdrowia Publicznego -Państwowego Zakładu Higieny (NIZP -PZH) w Warszawie. W niniejszym artykule zawarto również informacje dotyczące taksonomii wektorów poszczególnych czynników etiologicznych chorób tej grupy i ich rezerwuarów oraz możliwości transmisji przedstawionych drobnoustrojów. Ryzyko zakażenia nimi dotyczy szczególnie osób przebywających na terenach leśno-łąkowych w celach zarówno rekreacyjnych, jak i zawodowych (pracowników terenów leśnych, rolników, osób związanych z łowiectwem). Artykuł zawiera najnowsze dane z zakresu epidemiologii, etiopatogenezy, symptomatologii, diagnostyki laboratoryjnej i wpływających na nią czynników, opracowane z uwzględnieniem obowiązują-cych na terenie Polski zaleceń Polskiego Towarzystwa Epidemiologów i Lekarzy Chorób Zakaźnych oraz rekomendacji Krajowej Izby Diagnostów Laboratoryjnych. Szczególny nacisk położono na problematykę współczesnych metod laboratoryjnych wykorzystywanych w trudnej diagnostyce chorób odkleszczowych z uwzględnieniem algorytmów diagnostycznych oraz fazy przedanalitycznej (rodzaj materiału biologicznego) i analitycznej tych badań (metody referencyjne, skuteczność poszczególnych technik, czynniki interferujące, prawidłowość postępowania diagnostycznego). Med. Pr. 2016;67(1):73-87 Słowa kluczowe: epidemiologia, boreliozy, zoonozy, kleszcze, przenosiciele chorób, kliniczne techniki laboratoryjne AbstractThe article presents an overview of diagnostics of tick-borne diseases in Poland, which form one of the most prevalent group of occupational illnesses in the Polish area. This is a current issue due to a constantly growing number of tick-borne infections, i.e., Lyme borreliosis, tick-borne encephalitis, tularemia, Q fever, human granulocytic anaplasmosis and babesiosis. The scale of the problem is well illustrated by the latest reports of the Polish National Institute of Public Health -National Institute of Hygiene (NIPH -NIH). The article also covers the taxonomy of vectors of etiological factors, as well as their reservoirs and possible transmission to humans. The highest risk of tick-borne infection is particularly connected with people either resting or working in the forest or meadow surroundings (i.e., foresters, farmers, hunters). The article contains up-to-date data on epidemiology, etiopathogenesis, symptomatology, laboratory medicine and factors affecting the credibility of results according to current recommendations of the Polish Society of Epidemiology and Physicians of Infectious Diseases and the Polish National Chamber of ...
