Variola (smallpox) virus is classified as class A of potential biological weapons, due to its microbiological, genetic, antigenic and epidemiological characteristics. The potential danger is more real because vaccination against smallpox has stopped since disease eradication in 1979. That is why we want to share our unique, rich experience and acquired knowledge in the fight against this highly...

In response to identified deficiencies in the passive surveillance system for measles in Victoria and the move towards local disease elimination and global disease eradication, a system of enhanced measles surveillance was introduced in 1997. Each case is contacted and a structured telephone questionnaire is completed, collecting information on symptomatology and encouraging serological confirm...

On March 20, 2000, a suspected vesicular disease in cattle was reported to the National Veterinary Research and Quarantine Service (NVRQS) of the Republic of Korea. This represented the index case of a foot-and-mouth disease (FMD) outbreak, which spread through several provinces. The Republic of Korea had been free of FMD for 66 years prior to the reintroduction of the virus and had recently su...

Motivated by the failure of current methods to control dengue fever, we formulate a mathematical model to assess the impact on the spread of a mosquito-borne viral disease of a strategy that releases adult male insects homozygous for a dominant, repressible, lethal genetic trait. A dynamic model for the female adult mosquito population, which incorporates the competition for female mating betwe...

  Background: The effectiveness of classic standard triple therapy regimen of helicobacter pylori (H. pylori) eradication has decreased to unacceptably low levels, largely related to development of resistance to metronidazole and clarithromycin. Thus successful eradication of H. pylori infections remains challenging. Therefore alternative treatments with superior effectiveness and safety should...

background: half of the world's population is infected with helicobacter pylori. this organism is one of the main causes of peptic ulcer disease, gastritis and gastric cancer. this infection is most frequently acquired in childhood. there is strong evidence that eradication of infection improves healing and reduces the risk of recurrence and rebleeding in patientswith duodenal or gastric ulcer....
