Standardized Laboratory Feeding of Larval Aedes japonicus japonicus (Diptera: Culicidae).

The Asian bush mosquito (Aedes japonicus japonicus, Theobald 1901) is an invasive culicid species which originates in Asia but is nowadays present in northern America and Europe. It is a competent vector for several human disease pathogens. In addition to the public health threat, this invasive species may also be an ecological threat for native container-breeding mosquitoes which share a similar larval habitat.

Genomic resources and genetic diversity of captive lesser kudu (Tragelaphus imberbis).

The lesser kudu (Tragelaphus imberbis) is a spiral-horned antelope native to northeastern Africa. Individuals kept in zoological gardens are suspected to be highly inbred due to few founder individuals and a small breeding stock. A morphological study suggested two distinct subspecies of the lesser kudu.

Mitochondrial sequences reveal a clear separation between Angolan and South African giraffe along a cryptic rift valley.

Background: The current taxonomy of the African giraffe (Giraffa camelopardalis) is primarily based on pelage pattern and geographic distribution, and nine subspecies are currently recognized. Although genetic studies have been conducted, their resolution is low, mainly due to limited sampling. Detailed knowledge about the genetic variation and phylogeography of the South African giraffe (G.

Evolution of adefovir-resistant HBV polymerase gene variants after switching to tenofovir disoproxil fumarate monotherapy.

Background: Tenofovir disoproxil fumarate (TDF), an acyclic nucleotide analogue was shown to be effective in many HBV-infected patients with resistance to adefovir dipivoxil (ADV). This observation is intriguing because in vitro studies show that HBV mutations selected by ADV confer cross-resistance to TDF. To assess the clinical relevance of this cross-resistance, we studied the evolution of HBV polymerase gene variants in patients with genotypic resistance against ADV (rtN236T and/or rtA181V/T) during TDF treatment.
