BACKGROUND Zika virus (ZIKV) and chikungunya virus (CHIKV) are highly pathogenic arthropod-borne viruses that are currently a serious health burden in the Americas, and elsewhere in the world. ZIKV and CHIKV co-circulate in the same geographical regions and are mainly transmitted by Aedes aegypti mosquitoes. There is a growing number of case reports of ZIKV and CHIKV co-infections in humans, bu...

T he spread of the Zika virus is raising fears that the virus’s most heartbreaking consequencebabies with microcephaly born to infected motherswill affect the U.S. and other countries as it has affected Brazil. The virus hitches a ride with Aedes aegypti mosquitoes, whose preference for biting humans makes them an ideal vector for transferring virus from one victim to another. Repellents are ...

Evidence from clinical trials of malaria vaccine candidates suggests that both cell-mediated and humoral immunity to pre-erythrocytic parasite stages can provide protection against infection. Novel pre-erythrocytic antibody (Ab) targets could be key to improving vaccine formulations, which are currently based on targeting antigens such as the circumsporozoite protein (CSP). However, methods to ...

In recent years, several European countries reported cases of imported chikungunya infection. We present the first imported clinically manifested chikungunya fever in Croatia. A 27-year-old woman returned to Croatia on 21 March 2016, after she stayed in Costa Rica for two months where she had noticed a mosquito bite on her left forearm. Five days after the mosquito bite she developed severe art...

The authors evaluated the effects on malaria vectors of bed nets impregnated with permethrin over the course of a 16-month controlled study in four communities of Northern Guatemala. Anopheles albimanus and An. vestitipennis were the known malaria vectors in the area. Households were allocated to one of three experimental groups: those receiving bed nets impregnated with 500 mg/m2 of permethrin...

BACKGROUND Anopheles gambiae is a major vector of malaria and lymphatic filariasis. The arthropod-host interactions occurring at the skin interface are complex and dynamic. We used a global approach to describe the interaction between the mosquito (infected or uninfected) and the skin of mammals during blood feeding. METHODS Intravital video microscopy was used to characterize several feature...

Malaria is transmitted when an infected Anopheles mosquito deposits Plasmodium sporozoites in the skin during a bite. Sporozoites are formed within oocysts at the mosquito midgut wall and are released into the hemolymph, from where they invade the salivary glands and are subsequently transmitted to the vertebrate host. We found that a thrombospondin-repeat containing sporozoite-specific protein...

Hereditary pasSage of yellow fever virus through mosquito eggs was first investigated by Marchoux and Simond (1906) who reported successful transmission to a human being through the first generation offspring of an infective mosquito. Rosenau and Goldberger failed to confirm this work; in fact none of thirteen susceptible human beings, bitten by mosquitoes reared from eggs of infected female st...

Introduction Malaria is a common tropical infection. It is a kind of mosquito borne infection. The pathogen is the protozoa in Plasmodium spp. The patient usually gets acute febrile illness after get mosquito bite at malarial area. The infection can still be seen in several countries. The cases can be presently seen not only in tropical but nontropical countries due to good transportation syste...

Aedes species mosquitoes transmit chikungunya virus, as well as dengue and Zika viruses, and bite most often during the day.* Infectious mosquito bites frequently occur in and around homes (1,2). Caribbean countries first reported local transmission of chikungunya virus in December 2013, and soon after, chikungunya virus spread throughout the Americas (3). Puerto Rico reported its first laborat...
