Allan T Showler, Jessica L Harlien
The lone star tick, Amblyomma americanum (L.), widely distributed across eastern, southeastern, and midwestern regions of the United States and south into Mexico, is an obligate blood feeder that attaches to three hosts during the larval, nymphal, and adult stages. White-tailed deer and wild turkey are common hosts, as well as a wide variety of other avian and mammalian hosts. Amblyomma americanum is the most frequently reported species of tick to bite humans in the southeastern and southcentral United States, and it can transmit diseases that include erhlichiosis, rickettsiosis, tularemia, and protozoan infections...

Off-leash dog parks may enhance human health, but may also lead to health risk through infection or canine aggression. Published evidence was reviewed to examine positive and negative public health impacts of off-leash dog parks, as well as strategies for enhancing benefits and mitigating risks. Evidence suggests that off-leash dog parks can benefit physical and social health, as well as community connectedness. While studies have documented shedding of zoonotic agents in dog parks, the risk of transmission to humans is relatively unknown...

Scorpion bites are a common problem in Southern parts of India. The sting of Mesobuthus tamulus belonging to the Buthidae family is known for being fatal. The toxidrome of scorpion sting is known for its effect on the cardiovascular system, and there have been rare reports of cerebrovascular accidents as well. We describe a case of lateral medullary syndrome secondary to scorpion sting. As per the knowledge of the authors, this is the first case report of the same.

We report a 54-year-old woman with scorpion bite. After 3 hours of admission, the patient developed sudden onset tachycardia with hypotension. Cardiac evaluation showed raised creatine kinase MB isoenzyme was elevated; ECG and two-dimensional echocardiography findings were suggestive of myocarditis. Subsequently, she developed transient ventricular tachycardia before developing abrupt onset, right hemiplegia, global aphasia and progressive worsening of sensorium 12 hours after the bite. MRI of brain revealed massive left middle cerebral artery (MCA) territory infarct...

This article describes the clinical progression of symptoms over a period of 5 days of a bite inflicted by a Philodromus sp. spider. Commonly known as 'running spiders', these are not considered to be harmful to humans. This report, however, is the first description of an actual bite by a member of this group of spiders showing cytotoxic envenomation. Management of the bites should be as recommended for other cytotoxic spider bites.

BACKGROUND: Social insects form densely crowded societies in environments with high pathogen loads, but have evolved collective defences that mitigate the impact of disease. However, colony-founding queens lack this protection and suffer high rates of mortality. The impact of pathogens may be exacerbated in species where queens found colonies together, as healthy individuals may contract pathogens from infectious co-founders. Therefore, we tested whether ant queens avoid founding colonies with pathogen-exposed conspecifics and how they might limit disease transmission from infectious individuals...

Haemorrhage is a common clinical manifestation in envenomings caused by bites from snakes of the family Viperidae. Therefore, knowing the haemorrhagic potential of venoms and the capacity of antivenoms to neutralise this effect are of paramount relevance in toxinology. The most widely used method for quantifying haemorrhage involves the intradermal injection of venom (or a mixture of venom/antivenom) in mice, and the assessment of the resulting haemorrhagic area in the inner side of the skin. Although this method allows a straightforward assessment of the haemorrhagic activity of a venom, it does not account for haemorrhagic lesions having a similar area but differing in the depth and intensity of haemorrhage...

Even if wine and cheese have long been consumed together, there is little sensory evidence on how wine can influence the perception of cheese. In this work 4 cheeses were dynamically characterized in terms of dominant sensations without and with wine consumption in between intakes. The tasting protocol was based on multi-intake temporal dominance of sensations (TDS) coupled with hedonic rating. Frequent wine and cheese consumers (n = 31) evaluated 4 cheeses (Epoisses, Chaource, and 2 different Comté) over 3 consecutive bites...

BACKGROUND: Sand fly saliva compounds are able to elicit specific immune responses that have a significant role in Leishmania parasite establishment and disease outcome. Characterizing anti-saliva immune responses in individuals living in well defined leishmaniasis endemic areas would provide valuable insights regarding their effect on parasite transmission and establishment in humans. METHODOLOGY/PRINCIPAL FINDINGS: We explored the cellular and humoral immune responses to Phlebotomus (P...

The structural risk of West Nile Disease results from the usual functioning of the socio-ecological system, which may favour the introduction of the pathogen, its circulation and the occurrence of disease cases. Its geographic variations result from the local interactions between three components: (i) reservoir hosts, (ii) vectors, both characterized by their diversity, abundance and competence, (iii) and the socio-economic context that impacts the exposure of human to infectious bites. We developed a model of bird-borne structural risk of West Nile Virus (WNV) circulation in Europe, and analysed the association between the geographic variations of this risk and the occurrence of WND human cases between 2002 and 2014...

The leaves of Aster yomena (Kitam.) Honda have long been used as a traditional herb for treating disorders including coughs, asthma, and insect bites. According to recent studies, A. yomena leaf extracts have several pharmacological properties, including anti-inflammatory, antioxidant, and anti-asthmatic activities. However, little information is available regarding their anti-obesity effect. In this study, we investigated the inhibitory effect of the ethanol extracts of A. yomena leaves (EEAY) on adipocyte differentiation and adipogenesis using 3T3-L1 preadipocytes...

BACKGROUND: The effectiveness of malaria prevention with long-lasting insecticidal nets and indoor residual spraying is limited by emerging insecticide resistance, evasive mosquito behaviours that include outdoor biting, sub-optimal implementation and inappropriate use. New vector control interventions are required and their potential effectiveness will be enhanced if existing household perceptions and practices are integrated into intervention design. METHODS: This qualitative descriptive study used focus groups discussions, in-depth interviews and photovoice methods to explore mosquito control perceptions and practices among residents in four study sites in Dar es Salaam, Tanzania...

BACKGROUND: The Asian tiger mosquito Aedes albopictus is a highly invasive species and competent vector of several arboviruses (e.g. dengue, chikungunya, Zika) and parasites (e.g. dirofilaria) of public health importance. Compared to other mosquito species, Ae. albopictus females exhibit a generalist host seeking as well as a very aggressive biting behaviour that are responsible for its high degree of nuisance. Several complex mosquito behaviours such as host seeking, feeding, mating or oviposition rely on olfactory stimuli that target a range of sensory neurons localized mainly on specialized head appendages such as antennae, maxillary palps and the mouthparts...

Background: Lack of access to rabies immunoglobulin (RIG) contributes to the high rabies mortality. A recombinant human monoclonal antibody (SII RMAb) was tested in a post-exposure prophylaxis (PEP) regimen in comparison to a human RIG (HRIG)-containing PEP regimen. Methods: This was a Phase 2/3 randomized, single blind, non-inferiority study conducted in 200 participants with WHO category III suspected rabies exposures. On Day 0, participants received either SII RMAb or HRIG (1:1 ratio) into wounds and if required, intramuscularly (IM) along with five doses of rabies vaccine IM on Days 0, 3, 7, 14 and 28...

Post exposure prophylaxis prevents human rabies and is accessible in Cambodia principally in Phnom Penh, the capital. Timely, affordable access to post-exposure prophylaxis is a challenge for the mainly rural population. We aimed to identify districts independently associated with post-exposure prophylaxis (PEP) noncompletion to position frontline vaccination centers. We analyzed the 2009-2013 database at the rabies prevention center of the Institut Pasteur du Cambodge, Phnom Penh. Logistic regressions identified non-geographic determinants of PEP noncompletion and districts after adjustment for these determinants...
