The geographic pattern of human risk for infection with Borrelia burgdorferi sensu stricto, the tick-borne pathogen that causes Lyme disease, was mapped eastern United States. map is based on standardized field sampling in 304 sites density Ixodes scapularis host-seeking nymphs infected B. burgdorferi, which closely associated risk. Risk factors presence and were used to model a continuous 8 km×8 km resolution predictive surface risk, including confidence intervals each pixel. Discontinuous...
The distribution and abundance of Ixodes scapularis were studied in Wisconsin, northern Illinois, portions the Upper Peninsula Michigan by inspecting small mammals for ticks collecting questing at 138 locations state parks natural areas. Environmental data gathered a local level (i.e., micro meso levels), geographic information system (GIS) was used with several digitized coverages environmental to create habitat profile each site grid map Wisconsin Illinois. Results showed that presence I....
The risk of Lyme disease for humans in the eastern United States is dependent on density host-seeking Ixodes scapularis Say nymphal stage ticks infected with Borrelia burgdorferi. Although many local and regional studies have estimated using these parameters, this first large-scale study a standardized methodology. Density I. nymphs was measured by drag sampling closed canopy deciduous forest habitats 95 locations spaced among 2 degrees quadrants covering entire east 100th meridian. Sampling...
ABSTRACT Aim Ixodes scapularis is the most important vector of human tick‐borne pathogens in United States, which include agents Lyme disease, babesiosis and anaplasmosis, among others. The density host‐seeking I. nymphs an component risk for acquiring Borrelia burgdorferi , aetiological agent disease. In this study we used climate field sampling data to generate a predictive map that can be by public, physicians public health agencies assist with diagnosis reporting better target disease...
The blacklegged tick, Ixodes scapularis, is of significant public health importance as a vector Borrelia burgdorferi, the agent Lyme borreliosis. timing seasonal activity each immature I. scapularis life stage relative to next critical for maintenance B. burgdorferi because larvae must feed after an infected nymph efficiently acquire infection from reservoir hosts. Recent studies have shown that some strains do not persist in primary host more than few weeks, thereby shortening window...

Vector surveillance is often used to predict tick-borne diseases in endemic regions. Active and passive vector systems offer differing benefits limitations; understanding how the outputs of these differ they correlate human disease essential public health decision-making. Minnesota between 2018 2023 present an opportunity for comparison methods. To (1) analyze, compare, contrast results active with crowd-sourced approaches, (2) explore sources risk Lyme disease. In this ecological...
We detected the DNA of an Anaplasma bovis-like bacterium in blood specimens from 4 patients United States with suspected tickborne illnesses. Initial molecular characterization this novel agent reveals identity to A. bacteria Dermacentor variabilis ticks collected multiple US states.

From 1998 to 2003, 4,935 hunter-killed deer in northern and central Illinois were examined for ticks; 4,066 blacklegged ticks, Ixodes scapularis Say, 6,530 winter Dermacentor albipictus (Packard) (Acari: Ixodidae), collected. I. was the predominant tick species portion of study area, with a decreasing north-to-south prevalence gradient.

The Companion Animal Parasite Council hosted a meeting to identify quantifiable factors that can influence the prevalence of tick-borne disease agents among dogs in North America. This report summarizes approach used and identified for further analysis with mathematical models canine exposure pathogens.

A 100 yr (1911-2011) examination of tick submissions was compiled from the U.S. National Tick Collection and three state databases to determine species occurrence in Nebraska Sixteen were identified including Amblyomma americanum (L.), Dermacentor variabilis (Say), albipictus (Packard), andersoni Stiles, Haemaphysalis leporispalustris Rhipicephalus sanguineus (Latreille), Otobius megrini (Dughs). maculatum Koch Ixodes scapularis Say only two four submissions, respectively, but all...
A novel coccidian parasite from the kidney of big brown bats (Eptesicus fuscus) is described. This (Nephroisospora eptesici nov. gen., n. sp.) was associated with a generally mild, focal or multifocal, well-demarcated cortical renal lesion less than 1 mm in diameter. The represented cystic, dilated tubules hypertrophied tubular epithelial cells and present kidneys 29 590 bats. Numerous parasites various stages development were within cyst lumina. Oocysts collected cystic tubules....

Abstract Reported cases of Lyme disease in Nebraska have been assumed to be imported from other endemic areas. Previous surveillance efforts provided no evidence established populations as only individual specimens Ixodes scapularis (Say) had collected. In the winter 2018, adult I. were found on a dog at Two Rivers State Recreation Area, Douglas County, prompting tick collection site and nearby natural May 2019, all life stages host-seeking collected using dragging flagging techniques sites...
Abstract Hard ticks (Acari: Ixodidae) have been historically identified by morphological methods which require highly specialized expertise and more recently DNA-based molecular assays that involve high costs. Although both approaches provide complementary data for tick identification, each method has limitations restrict their use on large-scale settings such as regional or national surveillance programs. To overcome those obstacles, the matrix-assisted laser desorption/ionization...

Routine serologic testing for Avian metapneumovirus (AMPV) infection of turkey flocks at slaughter is currently being used to monitor changes in the occurrence AMPV endemic areas and can also be detect emergence unaffected areas. Because costs associated with false-positive results, particularly that are free infection, there a need obtain improved estimates flock-level specificity (SP). The objective this study was estimate SP program processing using standard enzyme-linked immunosorbent...
