Prevalence of Borrelia miyamotoi and Borrelia burgdorferi sensu lato in questing ticks from a recreational coniferous forest of East Saxony, Germany

Publication date: Available online 18 August 2017 Source:Ticks and Tick-borne Diseases Author(s): Sándor Szekeres, Jenny Lügner, Volker Fingerle, Gabriele Margos, Gábor Földvári The hard tick Ixodes ricinus is the most important vector of tick-transmitted pathogens in Europe, frequently occurring in urban parks and greenbelts utilized for recreational activities. This species is the most common vector of the causative agents of Lyme borreliosis in Europe. Similarly, the species spreads Borrelia miyamotoi, causing a relapsing-fever like illness. A total of 1774 Ixodes ricinus (50 females, 68 males, 840 nymphs and 818 larvae) were collected with flagging between March and September 2014 in a coniferous forest patch in Niederkaina near the town of Bautzen in Saxony, Germany. To measure questing tick density a time-based density estimating method was utilized. From each month, a total of 100 adults and nymphal ticks and all larvae (pools of 10 individuals per tube/month) were selected for the molecular analyses. For simultaneous detection of B. burgdorferi s.l. and B. miyamotoi a duplex real-time PCR targeting the flaB locus was performed. Prevalence of B. burgdorferi s.l. was 9.4% (female: 6%, male: 2.9%, nymph: 12.2%, larva: 0%) and minimum prevalence of B. miyamotoi was 1.2% (female: 0%, male: 4.3%, nymph: 2.8%, larva: 0.1%) in the 714 samples with real-time polymerase chain reaction. A real-time PCR reaction was utilized first to target the his...

In this study, we used PCR-based methods to provide the first evidence of Borrelia burgdorferi sensu lato (s.l.) infections in the three bat-associated tick species collected from ten bat species sampled in Poland and Romania. B. burgdorferi s.l. was detected in 24% (64/266) of tick samples, and 40.3% (60/149) of the bats carried infected chiropterophilic ticks.In Poland, the B. burgdorferi s.l. infection prevelance of I. ariadnae ticks parasitizing Myotis species was four times higher compared to the I. vespertilionis ticks derived from Rhinolophus hipposideros bats (44.4% vs.10%, respectively). The observed differences i...

Authors: BrodziƄski S, Nasierowski T Abstract In the second part of the article case reports of three patients were presented. All patientswere treated for Borrelia infection and all of them developed psychotic disorders. History of each patient was different, as well as the probability of causal relationship between neuroborreliosis and psychosis. The first case concerns a female patient with no former psychiatric history, who developed psychotic episode secondary to neuroborreliosis. Psychotic disorders resolved after antibiotic treatment. In the second case, a male patient was previously twice hospitalized in p...

This study was aimed to know epidemiological aspects of Borrelia spp. in a protected urban area of Buenos Aires city, Argentina, where thousands of people visit this area for recreational purposes. Ticks were collected from vegetation, birds and dogs. Three hundred and forty birds belonging to 43 species, 41 genera, 18 families and six orders were captured (90.3% corresponded to the order Passeriformes). One hundred and twenty ticks were collected from 47 birds (13.8%) belonging to 10 species (23.2%), all of them from to the order Passeriformes (Emberizidae, Furnariidae, Parulidae, Thraupidae, Troglodytidae, Turdidae). Tic...

In this study, B. burgdorferi-negative dogs were inoculated with B. turicatae, and seroconversion was confirmed by the rBipA (recombinant Borrelia immunogenic protein A) Western blot. Seropositive samples were tested with commercial and veterinary diagnostic laboratory B. burgdorferi-based tests. Borrelia turicatae-seroreactive samples cross-reacted with a whole-cell indirect fluorescent antibody (IFA) test and two multiantigen tests, but not with single-antigen tests using C6. Cross-reactivity with TBRF can confound epidemiology and surveillance efforts and confuse recommendations made by veterinarians for prevention and ...

Cecere, Fernando Spina, Federica MonacoAbstractThe continuous flow of billions of birds between Africa and Europe creates an “ecological bridge” between physically remote areas. Migratory birds fly south from their breeding grounds during late summer/fall and fly back in spring. These movements regulate the spread of internal and ex...

Tick-borne relapsing fever (TBRF), characterized by recurring febrile episodes, is globally distributed and among the most common bacterial infections in some African countries. Despite the public health concern that this disease represents, little is known regarding the virulence determinants required by TBRF Borrelia during infection. Because the chromosomes of TBRF Borrelia show extensive colinearity with those of Lyme disease (LD) Borrelia, the exceptions represent unique genes encoding proteins that are potentially essential to the disparate enzootic cycles of these two groups of spirochetes. One such exception is a g...

Authors: Serra V, Krey V, Daschkin C, Cafiso A, Sassera D, Maxeiner HG, Modeo L, Nicolaus C, Bandi C, Bazzocchi C Abstract Ixodes ricinus is the most common tick species parasitizing humans in Europe, and the main vector of Borrelia burgdorferi sensu lato, the causative agent of Lyme disease in the continent. This tick species also harbors the endosymbiont Midichloria mitochondrii, and there is strong evidence that this bacterium is inoculated into the vertebrate host during the blood meal. A high proportion of tick bites remains unnoticed due to rarity of immediate symptoms, implying the risk of occult tick-borne ...

The American Lyme Disease Foundation is dedicated to the prevention, diagnosis, and treatment of Lyme disease which, in the United States, has been defined historically as a tick-borne bacterial infection caused by the spirochete, Borrelia burgdorferi sensu stricto. Through its website, the Foundation plays a major role in providing reliable and scientifically accurate information to the public, medical community and various public health agencies about Lyme disease and its impact on human health.
