Timing Information Propagation in Interactive Networks.

Animal behavior is greatly influenced by interaction between peers as well as with the environment. Understanding the flow of information between individuals can help decipher their behavior. This applies to both the microscopic and macroscopic levels, from cellular communication to coordinated actions by humans.

Outbreak of West Nile virus infection in humans, Romania, July to October 2010.

A total of 57 cases of West Nile virus infection (54 with neuroinvasive infection and three with fever) were identified in Romania between July and October 2010.The median age of the cases was 53.4 years, with the highest incidence in the age group 60–69 years.

Genetic and phenotypic variation of the malaria vector Anopheles atroparvus in southern Europe.

Background: There is a growing concern that global climate change will affect the potential for pathogen transmission by insect species that are vectors of human diseases. One of these species is the former European malaria vector, Anopheles atroparvus. Levels of population differentiation of An.

Mosquitoes of the Anopheles maculipennis group (Diptera: Culicidae) in Romania, with the discovery and formal recognition of a new species based on molecular and morphological evidence.

Mosquitoes of the Anopheles maculipennis group were collected in five districts of Romania (Constant,a, Giurgiu, Ilfov, Mehedint,i and Suceava) between March 2000 and June 2003. Two hundred and ninety-seven specimens were identified by molecular methods. Nuclear rDNA ITS2 sequences of 178 specimens were compared with GenBank sequences for nine known Palaearctic species of the group, and 119 specimens were identified using an ITS2 PCR-RFLP assay developed during the study.

Screening of some Romanian plants for their activity against medically important insects.

The effects of the action of extracts from 82 plant species included in 39 families of indigenous flora against the larvae and adults of house fly (Musca domestica), the mosquitoes (Aedes aegypti and Anopheles atroparvus) and the German cockroach (Blattella germanica) are presented. Some of the extracts were prepared from air-dried and ground plant material which was exhaustively extracted with successive solvents of different polarity: ethyl ether, ethyl alcohol and water. Other extracts were prepared either by distillation of the whole water extracts of 24 hours macerated plants or by water extraction from residues of plants remained after distillation.
