Utah’s Great Salt Lake may dry up within 5 years
North America’s largest saline lake could be gone by 2028 if water inflows are not restored, researchers warned last week. The Great Salt Lake in Utah has lost nearly three-quarters of its water and 60% of its surface area since 1950, a report from 32 scientists at multiple institutions concludes, and a recent drought has accelerated the losses. To restore the lake, farmers, homeowners, and others
will need to reduce the amount of water they take from feeder streams by 30% to 50%
. If they don’t, the continent could lose a key habitat ...

Experimental Study on Plasmodium berghei, Anopheles Stephensi, and BALB/c Mouse System: Implications for Malaria Transmission Blocking Assays.
Conclusion: This study helps to understand the biology of vertebrate-parasite and mosquito-malaria interactions that may aid in the development of a new generation of drug/vaccine and vector-based measures for malaria control.

Longitudinal monitoring of anti ‐saliva antibodies as markers of repellent efficacy against Phlebotomus perniciosus and Phlebotomus papatasi in dogs
Dogs naturally exposed toLeishmania vectors, the sandfliesPhlebotomus perniciosus andPhlebotomus papatasi, and treated preventively with sandfly repellents developed antibodies against the insects' salivary proteins.
Anti ‐P. perniciosus and ‐P. papatasi saliva antibody concentrations were low, which suggests the repellent limited sandfly bites and is useful in canine leishmaniasis control.
Longitudinal monitoring of anti ‐saliva antibodies is a good method of marking insect repellent efficacy againstP. perniciosus andP. papatasi in dogs. AbstractA 2 ‐year longitudinal study of enzyme‐linked immunosorbent assay (...

Can Subclinical Infestation by Paralyzing Dermacentor andersoni (Acari: Ixodidae) Induce Immunity to Tick Paralysis in Sheep?
Cattle and sheep can develop immunity to paralysis caused by Dermacentor andersoni Stiles; however, this has been reported only in animals that were initially challenged with a high dose of ticks and exhibited clear symptoms of paralysis. Paralysis in sheep occurs in a dose-dependent fashion, with no paralysis occurring in sheep exposed to <0.2 ticks per kilogram sheep weight, and 100% paralysis in sheep exposed to >0.8 ticks per kilogram. This experiment was conducted to determine if sheep exposed to a low dose of ticks would also develop immunity to paralysis. Sheep were exposed to either a low (0.2 ticks per kilog...

Temporal genetic stability of Stegomyia aegypti (= Aedes aegypti) populations
Abstract
The mosquito Stegomyia aegypti (= Aedes aegypti) (Diptera: Culicidae) is the primary vector of viruses that cause yellow fever, dengue and Chikungunya fever. In the absence of effective vaccines, the reduction of these diseases relies on vector control strategies. The success of these strategies is tightly linked to the population dynamics of target populations. In the present study, 14 collections from St. aegypti populations separated by periods of 1–13 years were analysed to determine their temporal genetic stability. Although temporal structure is discernible in most populations, the degree of temporal diffe...

Concern about rise in UK Lyme disease cases
"Surging numbers of people are being diagnosed with Lyme disease as cases spread from rural areas to the suburbs," the Daily Mail reports. The ongoing rise in Lyme disease cases in the UK – thought to be driven by climate change, leading to warmer winters – has been known by public health officials for some time. Reported cases in England and Wales rose from 268 in 2001 to 959 in 2011, but the true figure is thought be much higher. Current estimates put the actual figure at around 3,000 cases a year in England and Wales.It may also be the case that the disease is, as the Mail puts it, "moving into t...

Morphological characteristics and developmental changes of the ovary in the tick Haemaphysalis longicornis Neumann
Abstract
Haemaphysalis longicornis (Ixodida: Ixodidae) is an important vector of transovarially transmitted parasites of the genus Babesia (Piroplasmida: Babesiidae). In the present study, we investigated the morphological characteristics and developmental changes of the ovary of H. longicornis. We show that the ovary of H. longicornis has a single tubular structure and is surrounded by a tunica propria. There is a longitudinal groove along one side of the ovary. During feeding and after engorgement, great changes can be observed in the ovary of H. longicornis and two rapid growth phases can be detected. The number o...
