OBJECTIVE: Canine babesiosis is a common and clinically significant tick-borne disease caused by haemoprotozoan parasites of the genus Babesia. Acute renal failure is considered to be one of the most prevalent complications of canine babesiosis. This complication leads to a decrease in the glomerular filtration rate and in consequence causes azotemia and uremia. The objective of this study was to assess the localization and extent of renal damage in dogs infected with Babesia canis using an urinary marker for glomerular (urinary immunoglobulin G, uIgG), proximal tubular dysfunction (urinary retinol binding protein, uRBP) and distal tubular dysfunction (urinary Tamm-Horsfal protein, uTHP)...

In this study, ticks from pastoral communities in Kenya were tested for Rickettsia spp. infections in geographical regions where the presence of tick-borne arboviruses had previously been reported. Rickettsial and arbovirus infections have similar clinical features which makes differential diagnosis challenging when both diseases occur. The tick samples were tested for Rickettsia spp. by conventional PCR using three primer sets targeting the gltA, ompA, and ompB genes followed by amplicon sequencing. Of the tick pools screened, 25% (95/380) were positive for Rickettsia spp...

Arthropods, especially ticks and mosquitoes, are the vectors for a number of parasitic and viral human diseases including malaria, sleeping sickness, Dengue and Zika. Yet arthropods show tremendous individual variation in their capacity to transmit disease. A key factor in this capacity is genetically encoded immune factors that counteract infection by the pathogen. Arthropod-specific pattern recognition receptors and protease cascades detect and respond to infection. Proteins such as antimicrobial peptides, thioester-containing proteins, and transglutaminases effect responses such as lysis, phagocytosis, melanization and agglutination...

Crimean-Congo hemorrhagic fever (CCHF) is a tick borne viral disease which can also be transmitted by direct contact with blood or tissue specimens of infected animals or humans. We present a fatal case of CCHF, who was diagnosed after death, and describe the post-exposure management plan for the health care workers (HCWs) involved in her care. In total of 52 HCWs were involved in the patient's care and they were stratified into risk groups. Overall, 20 HCWs were grouped in high and intermediate risk groups, including the HCW with needle stick injury...

Rickettsiae are obligate intracellular bacteria that have small genomes as a result of reductive evolution. Many Rickettsia species of the spotted fever group (SFG) cause tick-borne diseases known as "spotted fevers." The life cycle of SFG rickettsiae is closely associated with that of the tick, which is generally thought to act as a bacterial vector and reservoir that maintains the bacterium through transstadial and transovarial transmission. Each SFG member is thought to have adapted to a specific tick species, thus restricting the bacterial distribution to a relatively limited geographic region...

BACKGROUND: Tick-borne diseases, particularly Lyme disease, are emerging across the northern hemisphere. In order to manage emerging diseases and predict where emergence will likely occur, it is necessary to understand the factors influencing the distribution, abundance and infection prevalence of vector species. In North America, Lyme disease is the most common vector-borne disease and is transmitted by blacklegged ticks. This study aimed to explore the abiotic and environmental drivers of density and infection prevalence of western blacklegged ticks (Ixodes pacificus) in southern California, an understudied and densely populated region of North America...

The genus Anaplasma (Rickettsiales: Anaplasmataceae) comprises obligate intracellular Gram-negative bacteria that are mainly transmitted by ticks, and currently includes six species: Anaplasma bovis, Anaplasma centrale, Anaplasma marginale, Anaplasma phagocytophilum, Anaplasma platys, and Anaplasma ovis. These have long been known as etiological agents of veterinary diseases that affect domestic and wild animals worldwide. A zoonotic role has been recognized for A. phagocytophilum, but other species can also be pathogenic for humans...

The tick-borne disease Rocky Mountain spotted fever (RMSF) can have deadly outcomes unless treated appropriately, yet nonspecific flu-like symptoms complicate diagnosis. Occupational health nurses must have a high index of suspicion with symptomatic workers and recognize that recent recreational or occupational activities with potential tick exposure may suggest RMSF.

Since the mid-19th century, human activities have increased greenhouse gases such as carbon dioxide, methane, and nitrous oxide in the Earth's atmosphere that resulted in increased average temperature. The effects of rising temperature include soil degradation, loss of productivity of agricultural land, desertification, loss of biodiversity, degradation of ecosystems, reduced fresh-water resources, acidification of the oceans, and the disruption and depletion of stratospheric ozone. All these have an impact on human health, causing non-communicable diseases such as injuries during natural disasters, malnutrition during famine, and increased mortality during heat waves due to complications in chronically ill patients...

: The brown dog tick, Rhipicephalus sanguineus sensu lato (Latreille, 1806), is an ectoparasite and disease vector of significant veterinary and public health importance that is distributed widely around the world. The intensive use of synthetic acaricides for tick control exerts a strong selective pressure for brown dog ticks to become resistant to them. Here, we investigated claims from the field regarding treatment failure associated with the use of veterinary products containing ivermectin (IVM) to control brown dog ticks infesting dogs in Yucatan state, Mexico...

BACKGROUND & OBJECTIVES: Many etiological agents of zoonoses are considered as significant biological hazard to people visiting forested areas frequently, for instance, hunters. They may be exposed to ticks, rodents, and birds as well as excreta/secretions of wild animals or contaminated water and soil. Hence, this population is at risk of contracting infection with pathogens such as Borrelia burgdorferi sensu lato (s.l.), Anaplasma phagocytophilum, Babesia spp., tick-borne encephalitis virus, Bartonella spp...

Rūta Mameniškienė, Peter Wolf
Epilepsia partialis contina (EPC) in a narrow definition is a variant of simple focal motor status epilepticus in which frequent repetitive muscle jerks, usually arrhythmic, continue over prolonged periods of time. In a broader definition (used in this review) it also includes non-motor manifestations otherwise known as aura continua. EPC may occur as a single episode, repetitive episodes, it may be chronic progressive or non-progressive. It appears as an unusual manifestation of epilepsy in which more typical paroxysmal events are partly or entirely replaced by the sustained repetition of seizure fragments in rapid succession...

Tick-borne pathogens transmitted by Ixodes scapularis Say (Acari: Ixodidae), also known as the deer tick or blacklegged tick, are increasing in incidence and geographic distribution in the United States. We examined the risk of tick-borne disease exposure in 9 national parks across six Northeastern and Mid-Atlantic States and the District of Columbia in 2014 and 2015. To assess the recreational risk to park visitors, we sampled for ticks along frequently used trails and calculated the density of I. scapularis nymphs (DON) and the density of infected nymphs (DIN)...

BACKGROUND: African animal trypanosomosis (AAT), transmitted by tsetse flies and tick-borne diseases are the main constraints to livestock production in sub-Saharan Africa. Vector control methods such as pour-on offer individual protection against ticks but not against tsetse so far, for which protection has always been communal, through a reduction of their density. The latter requires the treatment of a large part of the herd in a given landscape and is not instantaneous. METHODOLOGY/PRINCIPAL FINDINGS: Two prospective surveys were conducted to evaluate the efficacy and persistence of a pour-on formulation composed of cypermetrhin, chlorpyrifos, piperonyl butoxid and citronella (Vectoclor, CEVA Santé Animal)...

Ticks are important vectors of emerging and re-emerging zoonoses, the majority of which originate from wildlife. In recent times, this has become a global public health concern that necessitates surveillance of both known and unknown tick-borne pathogens likely to be future disease threats, as well as their tick vectors. We carried out a survey of the diversity of ticks and tick-borne pathogens in Kenya's Shimba Hills National Reserve (SHNR), an area with intensified human-livestock-wildlife interactions, where we collected 4297 questing ticks (209 adult ticks, 586 nymphs and 3502 larvae)...
