Over the past ten years there has been a significant rise in the number of people who present to emergency departments with Lyme disease. Although some patients remain asymptomatic many present with a rash around a previous tick bite and others may present with a range of debilitating symptoms that can be problematic if left untreated. Due to the growing prevalence of Lyme disease in the UK and the US this article gives an overview of the vector-borne condition and provides emergency nurses with information about the pathophysiology, prevention, presenting signs and symptoms and management.

Lyme disease is the most common vector-borne illness in North America, with the majority of cases occurring in the Northeast and upper Midwest. Lyme arthritis is the most prevalent manifestation of late-stage Lyme disease. Lyme arthritis typically presents as a monoarthritis or oligoarthritis in large joints such as the knee. Read More

Lyme disease ( infection) is increasingly recognized as a significant source of morbidity worldwide. Here, we show that blood plasmablasts and CD27 memory B cells are elevated in untreated Lyme disease, with higher plasmablast levels associated with more rapid resolution of clinical symptoms. Stronger serum reactivity to surface proteins and peptides from was also associated with faster resolution of clinical symptoms. Read More

Lyme borreliosis (LB) is the most common tick-borne infectious disease in North America, and it was designated as a national notifiable infectious disease in Korea in December 2010. While no cases in Jeju-do were recorded from 2012 to 2016, a recent survey reported that the seroprevalence of using enzyme-linked immunosorbent assays in horses in Jeju-do was 19.0% (95% confidence interval, 12.

The impact of a pathogen on the fitness and behaviour of its natural host depends upon the host-parasite relationship in a given set of environmental conditions. Here, we experimentally investigated the effects of one of the aetiological agents of Lyme disease in humans, on the fitness of its natural rodent host, the bank vole (), in semi-natural conditions with two contrasting host population densities. Our results show that can modify the reproductive success and spacing behaviour of its rodent host, whereas host survival was not affected. Read More

Northeastern China is a region of high tick abundance, multiple tick-borne pathogens and likely human infections. The spectrum of diseases caused by tick-borne pathogens has not been objectively evaluated in this region for clinical management and for comparison with other regions globally where tick-transmitted diseases are common. Based on clinical symptoms, PCR, indirect immunofluorescent assay and (or) blood smear, we identified and described tick-borne diseases from patients with recent tick bite seen at Mudanjiang Forestry Central Hospital.

The distribution, abundance and seasonal activity of vector species, such as ticks and mosquitoes, are key determinants of vector-borne disease risk, and are strongly influenced by abiotic and habitat conditions. Despite the numerous species of tick vectors in the heavily populated North American West Coast, all but Ixodes pacificus, the primary vector of the Lyme disease spirochete, is poorly characterized with regard to seasonal activity patterns and fine scale drivers of distribution and abundance, particularly in heavily populated regions of southern California. This lack of knowledge inhibits both scientific understanding and public health efforts to minimize vector exposure and risk of pathogen transmission to humans. Read More

Several recent studies have demonstrated the association of cat-related injuries with major depression and with depressiveness in the general population. It was suggested that cat-scratch disease, the infection with the bacterium , can be responsible for the observed association. However, no direct evidence for the role of the infection in this association has been published until now. Read More

Since 2011, Borrelia miyamotoi disease (BMD) has been reported in five countries in the northern hemisphere. The causative agent of BMD is transmitted by Ixodes ticks, which are also vectors of Lyme disease borreliae. In this study, we examined 459 cases of clinically suspected Lyme disease (LD group), and found twelve cases that were seropositive for the glycerophosphodiester phosphodiesterase (GlpQ) antigen derived from B.

Ticks are blood-feeding arthropods that can transmit pathogens to humans and animals, leading to serious infectious diseases such as Lyme disease. After single or multiple tick infestation, some animal species develop resistance to tick feeding, leading to reduced risk of pathogen transmission. In mice infested with larval ticks, both mast cells and basophils reportedly play key roles in the manifestation of acquired tick resistance (ATR), but it remains ill-defined how they contribute to it.

Tick dragging is an important tool used by public health for Ixodes scapularis surveillance to identify Lyme disease risk areas in Ontario, Canada. Concerns have been raised on the repeatability of tick dragging due to fluctuations that occur in the tick population in response to micro- and macroclimatic variations. Our objective was to assess the repeatability of tick dragging over a short timescale by examining three outcome measures: presence/absence of ticks, tick abundance, and likelihood of tick establishment based on an indicator developed by Clow et al.

Given the variable clinical signs attributed to Borrelia burgdorferi, including infectious arthritis, neurologic disease, and behavioral changes, B burgdorferi is an important differential for decreased performance in sport horses. The primary vectors (Ixodes tick species) are expanding their range and thus Borrelia species are located in a wider area, making exposure more likely. Due to regionally high seroprevalence and vague clinical signs, diagnosis of Lyme disease in the horse is believed overestimated. Read More

Lyme disease is emerging in southern Canada due to range expansion of the tick vector, followed by invasion of the agent of Lyme disease Borrelia burgdorferi sensu stricto. Strain diversity, as determined by Multi Locus Sequence Typing, occurs in this zone of emergence, and this may have its origins in adaptation to ecological niches, and have phenotypic consequences for pathogenicity and serological test performance.
