Oysters with potential for aquaculture are found throughout the tropics and subtropics, but few species have been cultured and in only a few tropical countries. This monograph reviews the biology, ecology and culture techniques, both experimental and commercial, used in the tropics; describes the problems associated with tropical oyster farming; and points out research needs to develop further ...

Dengue fever (DF) and dengue haemorrhagic fever (DHF) are important mosquito-borne viral diseases of humans and recognised as important emerging infectious diseases in the tropics and subtropics. There has been a considerable increase in the geographic spread, number of cases and severity of the disease in the past four decades, since there is a drastic change in the environment due to rapid ur...

Ornithodoros (Alectorobius) capensis Neumann, an ectoparasite of seabirds found circumglobally in the tropics and subtropics, has become established along the southeastern seacoast of the United States. The tick has been found feeding primarily on brown pelicans, Pelecanus occidentalis, but also has been found on the laughing gull, Larus atricilla, and the American oystercatcher, Haematopus pal...

Parasitic infection still surprises us with amazing case presentation every ‎now and then. Intestinal nematode is a worldwide health problem ‎especially in humid hot areas. Strongyloides stercoralis (S. stercoralis) ‎is common soil- transmitted tropics subtropics. ‎Its severity ranges from asymptomatic immunocompetent ‎patients to hyperinfection even disseminated ‎immunocompromised patients. He...

Higher growing season temperatures can have dramatic impacts on agricultural productivity, farm incomes, and food security. We used observational data and output from 23 global climate models to show a high probability (>90%) that growing season temperatures in the tropics and subtropics by the end of the 21st century will exceed the most extreme seasonal temperatures recorded from 1900 to 2006...

Accidental infection with animal filarial worms in humans is a dilemma for clinicians and parasitologists throughout the world. To date a variety of such rare parasitoses have been reported mostly in tropics and subtropics. Human dirofilariasis is among those unusual zoonotic infections that occasionally have been observed in the eye and in subcutaneous areas exhibiting with nodule formation. F...

Dengue is a public health problem in the tropics and subtropics. There are several vaccine candidates in clinical development. However, there may be gaps in the new vaccine introduction after vaccine licensure before it becomes available in developing countries. In anticipation of the first dengue vaccine candidate to be licensed, Dengue Vaccine Initiative (DVI) and, its predecessor, Pediatric ...

Strongyloides stercoralis is an intes tinal roundworm transmitted primarily through barefoot skin exposure in the tropics or subtropics. Acute infection may present with papular rash, cough or wheezing, and gastrointestinal symptoms.1 Manifestations of chronic infection are present in up to half of infected patients and may include abdominal pain, diarrhea, vomiting, recurrent asthma, a Löffler...
