However, identifying the intermediate host of O. petrowi with traditional techniques would be difficult and time-consuming, especially considering there are more than 80 potential orthopteran hosts just in Texas. To screen a large number of samples quickly and effectively, primers for nested PCR (nPCR) were developed using the internal transcribed spacer 1 (ITS1) region. Then the nPCR was used to identify which of the 35 species collected from the Order Orthoptera were potential intermediate hosts of O. petrowi. With this technique, 18 potential intermediate hosts were identified. Later, we collected live specimens of species that tested positive to confirm the presence of larvae, but larvae were not found in the live specimens, nor in the extra tissue of the species that had tested positive for O. petrowi DNA. Despite this, this study demonstrated that nPCR is more sensitive than traditional techniques and can be a valuable tool in determining the intermediate hosts of parasites.","PeriodicalId":17889,"journal":{"name":"Kisaengch'unghak chapchi.

In addition to 1 nematode ( Trichuris sp.) and 1 symbiotic ciliate (Meistoma georychi), we collected mites of the genera Androlaelaps and Bathyergolichus as well as unidentified trombiculids from these hosts. Host specificity was high at either the species, genus, or family level for Androlaelaps spp. and Bathyergolichus spp. irrespective of geographic proximity, host phylogeny, or ecological conditions. Host sharing was more limited for helminths but observed among sympatric host species. Our results suggest that ecological similarity and geographic proximity may be more important determinants of host sharing than phylogeny within Bathyergidae.","PeriodicalId":17889,"journal":{"name":"Kisaengch'unghak chapchi.

Vossbrinck, Alexander J Diaz","doi":"10.1645/19-116","DOIUrl":"https://doi.org/10.1645/19-116","url":null,"abstract":"Ixodes scapularis is currently known to transmit 7 pathogens responsible for Lyme disease, anaplasmosis, babesiosis, tick-borne relapsing fever, ehrlichiosis, and Powassan encephalitis. Ixodes scapularis can also be colonized by endosymbiotic bacteria including those in the genus of Rickettsia. We screened 459 I. scapularis ticks submitted to the Connecticut Agricultural Experiment Station Tick Testing Laboratory with the objectives to (1) examine differences in infection prevalence of Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, and Borrelia miyamotoi, (2) evaluate whether prevalence of co-infections occur at the same frequency that would be expected based on single infection, and (3) determine the presence of rickettsial endosymbionts in I. scapularis. The prevalence of infection in I. scapularis was highest with Bo. burgdorferi sensu lato (nymph = 45.8%; female = 47.0%), followed by A. phagocytophilum (nymph = 4.0%; female = 6.9%), Ba. microti (nymph = 5.7%; female = 4.7%), and Bo. miyamotoi (nymph = 0%; female = 7.3%). We also identified rickettsial endosymbionts in 93.3% of I. scapularis. Nymphs were significantly more likely to be infected with Bo. burgdorferi if they were infected with Ba. microti, whereas adult females were significantly more likely to be infected with Bo. burgdorferi if they were infected with A. phagocytophilum. Our study suggests that the infection prevalence of Bo. burgdorferi is not independent of other co-circulating pathogens and that there is a substantially higher infection of Bo. miyamotoi in I. scapularis females compared with nymphs in this study. High prevalence of infection and co-infection with multiple pathogens in I. scapularis highlights the public health consequences in Connecticut, a state endemic for Lyme and other tick-borne diseases.","PeriodicalId":17889,"journal":{"name":"Kisaengch'unghak chapchi.

Spotted Ratfish specimens were collected during bottom-trawl surveys in Queen Charlotte Sound (QCS, n = 31) and off the west coast of Vancouver Island (WCVI, n = 242). In all instances, the flukes were found within the abdominal cavity. Most flukes were mature (intrauterine eggs were present) and ranged in length from 9.1 to 61.5 mm, with a mean ± SD length of 28.5 ± 12.1 mm (n = 52). Fluke length was positively correlated with Spotted Ratfish precaudal length (PCL), and no Spotted Ratfish smaller than 247-mm PCL was infected by O. hydrolagi. The overall prevalence (95% confidence interval [CI]) and mean intensity (95% CI) of O. hydrolagi were 27.8% (22.6-33.6) and 1.24 (1.09-1.43), respectively. Neither prevalence nor mean intensity differed between host location or host sex. The majority (86%) of infected hosts harbored a single fluke (range 1-5), but 4 Spotted Ratfish were infected with 3 or more flukes, which accounted for 16% of all observed O. hydrolagi. The fluke population exhibited an aggregated distribution with 80% of individuals found in 21% of the hosts, but among infected hosts there was low variability in the intensity of infection. This is the first ecological study of O. hydrolagi from its Spotted Ratfish host, and the first record of this trematode in Canadian waters, which extends the range of O. hydrolagi to include Canadian coastal Pacific waters.","PeriodicalId":17889,"journal":{"name":"Kisaengch'unghak chapchi.

We are reporting the presence of A. maculatum for the first time in Illinois, including a total of 18 specimens collected at 6 different sites during surveys in 2013 and 2019. Fourteen of these specimens were screened for Rickettsia parkeri, which resulted in the detection of this bacteria in 8 samples from 4 counties. By depositing these specimens in scientific collections, we provide materialistic evidence of their establishment in 2 counties. We urge health officials to rely on and use scientific collections to document the expansion of these and other vectors across the country. Additionally, we recommend that health practitioners become aware of the clinical similarities between Rocky Mountain Spotted Fever (caused by Rickettsia rickettsii) and \"tidewater\" fever (caused by R. parkeri).","PeriodicalId":17889,"journal":{"name":"Kisaengch'unghak chapchi.
