Epidemiological study of Lyme disease in Bulgaria.
CONCLUSIONS: Lyme disease is a serious health risk in Bulgaria especially in its northern part - regions on the north are the most vulnerable to a higher incidence of the disease. PMID: 31580560 [PubMed - in process]
Discussion Dengue is an important arboviral infection that affects about 40% of the world population. It is found mainly in topical and subtropical areas of the world mainly in developing countries but it range is spreading including the United States. A review of common arboviruses can be found here. It is a flaviavirus with 4 distinct serotypes named DENV-1 through DENV-4 and is spread by A. aegypti a day biting mosquito. Infection with one serotype confers immunity to that serotype but not the others. It does offer some protection for cross-infection but this only lasts a few months. Incubation period is 3-14 days with ...
We present the case of an atypical papillitis, probably caused by this bacterium. We suspected this because of the results on the indirect test bloods and the improvement of the symptoms after treatment. This entity should be considered as a possible diagnosis of atypical optical neuropathies, particularly if it occurs in an endemic area. PMID: 31167569 [PubMed - as supplied by publisher]
This study presented examples of base-calling DNA sequencing electropherograms routinely generated in a clinical diagnostic laboratory on DNA extracts of human blood specimens and ticks collected from human skin bites and from the environment. Since some of the tick samples tested were collected in Ireland, borrelial species or strains not known to exist in the United States were also detected by analysis of this 16S rRNA “core genome”. We recommend that hospital laboratories located in Lyme disease endemic areas begin to use a “core genome” sequencing test to routinely diagnose spir...
Abstract The castor bean tick Ixodes ricinus is one of the most abundant tick species in Europe, being able to parasitize a wide number of vertebrate hosts, including mammals, birds, and reptiles. This tick species has an important role as vector of zoonotic pathogens, including the causative agents of Lyme borreliosis (i.e. Borrelia burgdorferi sensu lato). Here, we provide insights on a new tick-host association (i.e. I. ricinus infesting snakes) in an area recently recognized as endemic for reptile-associated zoonotic species of Borrelia burgdorferi s.l..

We report rare manifestation of a common disease and emphasize the importance of considering LD in the differential diagnosis of acute transverse myelitis, particularly in residents of endemic areas.
Publication date: Available online 14 December 2018Source: Ticks and Tick-borne DiseasesAuthor(s): George Psevdos, Teresa Khoo, Robert Chow, Christopher L Romano, Scott CampbellAbstractIn North America, Lyme disease (LD) is caused predominantly by the spirochete Borrelia burgdorferisensu stricto, and is transmitted by blacklegged ticks. Long Island, New York, is highly endemic for the disease. The C6 peptide (C6P) is currently used as a screening test for LD in our institution. Our objective was to examine how screening with C6P concorded with diagnosis of LD at the Veterans Affairs Medical Center, Northport, Long Island. ...
This study shows that humus type can be indicative of nymph abundance. Three types of humus were observed: (1) moder, (2) mull, and (3) mull-moder humus. One of them, moder humus, which is characterized by a thick layer of fragmented leaves, was found in multivariate analyses to be strongly associated with the nymph abundance. This study demonstrates that factors such as saturation deficit do not suffice to explain the differences in nymph abundance among sites. The composition of the soil and especially the type of humus should also be taken into consideration when assessing acarological risk.
The objectives of this study were to use data from client-owned cats in an Ixodes scapularis endemic area to evaluate for clinical associations with diagnostic test results for Anaplasma phagocytophilum and Borrelia burgdorferi and to provide information from a group of cats with possible borreliosis as the cause of clinical manifestations of disease. All cases were evaluated at one clinic, medical records were evaluated, and sera from all cats were tested using one of two commercially available assays labeled for the use with dog sera (SNAP ® 4Dx® or SNAP® 4Dx® Plus; IDEXX Laboratories, Westbrook, ME).
CONCLUSION: We report this case to increase awareness among clinicians to include Lyme disease in the differential diagnosis of optic neuritis for unexplained cases of vision loss, particularly in Lyme endemic areas. PMID: 30048578 [PubMed - in process]
Conclusions: Clinical isolates of B. miyamotoi are highly susceptible to doxycycline, azithromycin and ceftriaxone in vitro Interestingly, as earlier described for tick isolates, amoxicillin shows poor in vitro activity against clinical B. miyamotoi isolates.
