  • Helicobacter pylori is one of the most commonly encountered human pathogens. It has been shown to be closely associated with peptic ulcer disease (PUD), gastric adenocarcinoma, and the gastric mucosa-associated lymphoid tissue (MALT) that may lead to gastric lymphoma. The current diagnostic methods include histology, microbiological culture, classic serology unease activity detection, polymerase chain reaction (PCR) and stool antigen detection. Its treatment modality options are multiple; however, a triple regimen consisting of a proton pump inhibitor (PPI), and two antibiotics for 10 to 14 days is preferred. Drug resistance is a growing problem in this organism and new therapeutic options are currently limited .

  • During the last two decades, the rapid increase in aquaculture world wide, particularly in finfish and shellfish culture, is the result of both area expansion and production intensification. Under these conditions, the prevalence and spread of infectious diseases have increased as a result of higher infection pressure and decreased resistance of the aquatic animals. Accordingly, the effective control of infectious diseases has become more and more important to development of aquaculture. Recently the Pathology Team of National Fisheries Research and Development(NFRDI), has played pivotal roles in establishing the national management and control system of aquatic animal health and disease by new legislative works and technical guidelines. Under the national aquatic animal disease control framework, the Pathology Team of NFRDI and MOMAF(Ministry of Maritime Affairs and Fisheries) should also establish effective management and regulations, with the support of enforcement and monitoring policies. In conjunction with effective aquatic disease national management, financial assistance or alternative compensation options for aquaculture should also be available in the event of production losses or eradication system.

  • Tuberculosis is a disease with high morbidity and mortality in children worldwide. Despite significant improvements in diagnostic methods, scientific researches and clinical trials for new regimens of treatment or prevention in adult tuberculosis, childhood tuberculosis has been relatively neglected. Children are at high risk of severe disease, and reactivation of latent infection in adulthood perpetuates the epidemic. Therefore, a policy of tuberculosis control in childhood should be emphasized to improve control in the total population. To understand the new view of childhood tuberculosis, this article describes changes in the disease's national epidemiology, new diagnostic tools and treatment strategies, and multi-drug resistance.

  • Local malaria transmission in the United Arab Emirates (UAE) came to an end in 1997. Nevertheless, UAE has been subjected to substantial importation of malaria cases from abroad, concerning both UAE nationals and immigrants from malarious countries with a total number of 2,119 cases in 2007. To evaluate a new DNA extraction technique using nested PCR, blood samples were collected from 132 individuals who presented to Infectious Diseases Department in Rashid Hospital, Dubai, and Central Department of Malaria Control with fever and persistent headache. Giemsa-stained blood films and ELISA test for malaria antibodies were carried out for detection of Plasmodium infection. Plasmodium infections were identified with the genus-specific primer set and species differentiation using nested PCR. A rapid procedure for diagnosis of malaria infections directly from dried blood spots using for the first time DNA extract from FTA Elute cards was evaluated in contrast to extraction techniques using FTA classic cards and rapid boiling technique. Our new simple technique for DNA extraction using FTA Elute cards was very sensitive giving a sensitivity of 100% compared to 94% using FTA classic cards and 62% in the rapid boiling technique. No complex preparation of blood samples was required prior to the amplification. The production cost of DNA isolation in our PCR assay was much less incomparable to that of other DNA extraction protocols. The nested PCR detected plasmodial infection and could differentiate P. falciparum from P. vivax, and also detected the mixed infection.

  • Following the Anthrax bioterrorism attacks in the US in 2001, the Korean government established comprehensive countermeasures against bioterrorism. These measures included the government assuming management of all infectious agents that cause diseases, including smallpox, anthrax, plaque, botulism, and the causative agents of viral hemorrhagic fevers (ebola fever, marburg fever, and lassa fever) for national security. In addition, the Korean government is reinforcing the ability to prepare and respond to bioterrorism. Some of the measures being implemented include revising the laws and guidelines that apply to the use of infectious agents, the construction and operation of dual surveillance systems for bioterrorism, stockpiling and managing products necessary to respond to an emergency (smallpox vaccine, antibiotics, etc.) and vigorously training emergency room staff and heath workers to ensure they can respond appropriately. In addition, the government's measures include improved public relations, building and maintaining international cooperation, and developing new vaccines and drugs for treatments of infectious agents used to create bioweapons.

  • Infectious bronchitis(IB) is a viral disease in which continued evolution of the virus is of paramount importance for annual endemics and epidemics in chickens. Since the isolation of IB viruses(IBVs) in the 1930s, over 50 serotypes or variants have been reported worldwide. Continuing evolution is most prominent in the suface glycoproteins of IBV but also occurs in other parts of the genome. This genetic variability results from accumulation of molecular changes that can occur by a number of different mechanisms including genetic drift (point mutations) and genetic shift(RNA recombination). GA98 is a new serotype of IBV identified recently in the United States. In this paper, the evolutionary trend of IBV will be discussed using GA98 serotype as a model.

  • Marek's disease (MD) is caused by a ubiquitous, lymphotropic alphaherpesvirus, MD virus (MDV). MD has been a major concern in the poultry industry due to the emergence of increasingly virulent strains over the last few decades that were isolated in the face of comprehensive vaccination. MD is characterized by a variety of clinical signs, amongst them neurological symptoms, chronic wasting, and most notably the development of multiple lymphomas that manifest as solid tumors in the viscera and musculature. Much work has been devoted to study MD-induced oncogenesis and genes involved in this process. Among the many genes encoded by MDV, a number have recently been shown to affect the development of tumors in chickens, one protein directly causing transformation of cells (Meq) and another being involved in maintaining transformed cells (vTR). Other MDV gene products modulate and are involved in early lytic in vivo replication, thereby increasing the chance of transformation occurring. In this review, specific genes encoded by MDV that are involved in the initiation and/or maintenance of transformation were briefly summarized, and limits of current vaccination and new control strategies against MD, particularly how modem molecular biological methods may be used to improve strategies to combat the disease in the future, were discussed.
