Arthropod-borne viruses, or arboviruses, are viruses that are transmitted through the bites of mosquitoes and ticks. There are numerous arboviruses throughout the world capable of causing human disease spanning different viral families and genera. Recently, dengue, chikungunya, and zika viruses have emerged as increasingly important arboviruses that can cause human disease, however no specific treatment or vaccine is available for them. In addition, ocular manifestations of these diseases have become more prevalent over the past few years...

Lyme borreliosis is the most frequent tick-borne infection in Europe. It is a multisystemic disease affecting the skin, joints, heart, in rare cases the eyes and regularly the nervous system. Taking current clinical and microbiological guidelines into account, neuroborreliosis can in general be diagnosed and treated successfully. An appropriate guideline-conform antibiotic treatment is effective and in most cases recovery from acute neuroborreliosis is complete. Nevertheless, the evidence base regarding pharmacological treatment needs reform and improvement...

Pesticides are used widely to control weeds and insect infestation in agricultural fields and various pests and disease carriers (e.g., mosquitoes, ticks, rats, and mice) in houses, offices, malls, and streets. As the modes of action for pesticides are not species-specific, concerns have been raised about environmental risks associated with their exposure through various routes (e.g., residues in food and drinking water). Although such hazards range from short-term (e.g., skin and eye irritation, headaches, dizziness, and nausea) to chronic impacts (e...

BACKGROUND: Lyme disease is the number one arthropod-transmitted disease in the US, and one of the diagnostic criteria for the illness is development of an erythematous bull's-eye rash around a tick bite that may expand over time, hence the term erythema migrans. However, there are other erythema migrans-like rashes, such as those from a condition known as southern tick-associated rash illness. This article describes a patient with an erythema migrans-like lesion similar to that associated with Lyme disease, resulting from a bite by a nymphal-stage lone star tick, Amblyomma americanum...

PURPOSE OF REVIEW: Tick-borne diseases are increasing in incidence and geographic distribution. Several diseases endemic to the United States have ophthalmic manifestations, including the most common tick-borne disease, Lyme borreliosis. As ocular complaints may lead a patient to seek medical evaluation, it is important to be aware of the systemic and ophthalmic manifestations of tick-borne diseases in order to make the correct diagnosis. RECENT FINDINGS: Vision-threatening ophthalmic manifestations are relatively common in Lyme disease and Rocky Mountain spotted fever...

Many decisions are made under suboptimal circumstances, such as time constraints. We examined how different experiences of time constraints affected decision strategies on a probabilistic inference task and whether individual differences in working memory accounted for complex strategy use across different levels of time. To examine information search and attentional processing, we used an interactive eye-tracking paradigm where task information was occluded and only revealed by an eye fixation to a given cell...

Tick-borne illnesses are a significant disease burden worldwide. Diagnosis is challenging and requires a high level of clinical suspicion. Ocular manifestations reported in association with tick-borne disease are mostly as case reports and small case series because of the relative infrequency with which they occur; however, given the global nature of health care and increase in travel in the 21st century, it is important for ophthalmologists to be aware of ocular manifestations of these diseases because early diagnosis may reduce morbidity and mortality...

We have killed wild animals for obtaining food and decimated forests for many reasons. Nowadays, we are burning fossil fuels as never before and even exploring petroleum in deep waters. The impact of these activities on our planet is now visible to the naked eye and the debate on climate change is warming up in scientific meetings and becoming a priority on the agenda of both scientists and policy decision makers. On the occasion of the Impact of Environmental Changes on Infectious Diseases (IECID) meeting, held in the 2015 in Sitges, Spain, I was invited to give a keynote talk on climate change, biodiversity, ticks and tick-borne diseases...

BACKGROUND: Theileria uilenbergi and T. luwenshuni are tick-borne protozoan parasites, transmitted by Haemaphysalis qinghaiensis and H. longicornis, respectively. They are the main causative agents of theileriosis in small ruminants in China. The disease has resulted in severe economic losses and hindered the development of sheep and goat husbandry industry in the endemic regions. METHODS: In this study, a colloidal gold-based immunochromatographic strip (ICS) was developed for the detection of T...

BACKGROUND: Though rickettsiosis is common in India, there is paucity of rickettsial retinitis (RR) reports from India. Moreover, rickettsial sub-types and their association with retinitis have not been studied. We are reporting a case series of presumed RR with their course of the disease, visual outcome, and association with rickettsial sub-type based on Weil-Felix test. FINDINGS: This is a retrospective study of 19 eyes of 10 patients presented to a single institution...

Early cutaneous Lyme disease, erythema migrans, may show different histopathologic patterns. The intent of this case series is to raise awareness of these findings to prevent misdiagnosis and keep this entity in the differential. Erythema migrans develops after a tick bite and subsequent infection with the spirochete, Borrelia burgdorferi. It most commonly manifests as a solitary, annular lesion with a bull's-eye appearance. Classic histopathologic findings include superficial and deep perivascular and interstitial lymphocytic infiltrates mixed with plasma cells and eosinophils...

The habits of birds make them more or less susceptible to parasitism by certain tick species. Therefore, while some bird species are typically found to be intensely infested, others are relatively unaffected. This study investigated the occurrence of ticks in Passeriformes inhabiting an Atlantic Forest fragment in southeastern Brazil, during the dry and rainy seasons, by means of parasitological indexes and multiple correspondence analysis, to determine the factors that influence tick parasitism in these birds...

In vivo reflectance confocal microscope (RCM) is a high-resolution non-invasive imaging technique that was initially focused on the diagnosis of skin cancers. A rising number of other indications have been later described for the diagnosis and management of inflammatory and infectious dermatological disorders. RCM can identify cutaneous parasites that are not visible to naked eye such as Sarcoptes scabiei and Demodex folliculorum and it allows to better identify the different body parts of bigger parasites such as ticks...

We describe a rare clinical finding of conjunctival tick attachment in a child. A 10-year-old boy presented to the clinic with right-eye itch. He was found to have a live tick firmly attached to his right temporal conjunctiva. The tick was identified as the larval stage of the paralysis tick, Ixodes holocyclus. The tick was removed completely by conjunctival excision. Although various methods of removing a tick have been described in the literature, the goal of treatment is the safe and complete removal of the tick to prevent further transmission of pathogens, allergens, and toxins to the patient...

A 53-year-old Japanese female developed a fever about two months after a tick bite. She also exhibited blurred vision, central scotoma in the left eye, left facial paresis and mild ataxia. A fundus examination revealed left disc swelling in the left eye. An ophthalmological examination showed decreased visual acuity with central scotoma in the left eye. We suspected neuroborreliosis because of the presence of pleocytosis and an elevated level of IL-6 in the cerebrospinal fluid (CSF), in addition to the characteristic neurological findings...

The most common transmission route of tick-borne Rickettsia is through tick bite; nevertheless, other transmission routes should also be considered. We report a case of rickettsial infection in a 15-year-old boy caused by accidental contamination of the conjunctiva through the infected fluid of a crushed engorged tick removed from a dog. Right eye pain, conjunctival hyperaemia with mucopurulent exudate, chemosis and eyelid oedema were the first signs and symptoms. Two days later, the boy developed fever, myalgia, headache, abdominal pain and was vomiting; physical examination showed multiple cervical adenopathies but no rash...
