ABSTRACT Anthrax is still an endemic disease in some countries in the world and has become a re-emerging disease in western countries with recent intentional outbreak. The aim of this study was to review our clinical experience with cutaneous anthrax cases. From the patient's files, transmission of the diseases, clinical findings and severity of infection, treatment and outcome of patients were recorded. Twenty-two cases were diagnosed as cutaneous anthrax in the last 7 years. Of these cases, 10 cases were severe form of cutaneous anthrax, 10 cases were mild form and 2 cases were toxemic shock due to cutaneous anthrax. The incubation period was between 1 and 17 days. The main clinical characteristics of the cases with severe cutaneous anthrax were fever, hemorrhagic bullous lesions surrounded by an extensive erythema and edema, and leukocytosis. Two cases with toxemic shock had low systolic blood pressure, apathy and toxemic appearance, leukocytosis, hypoalbuminemia & hyponatremia. Penicillin G was given in 15 cases, amoxicillin in 4 and other antibiotics in 3 cases for 3-10 days. Skin lesion left deep tissue scar in 4 cases and were grafted. Physicians working in endemic areas and also in western countries should be aware of all clinical forms of anthrax.

    ABSTRACT: Anthrax is an endemic disease in Turkey, among other countries of the world. The potential of Bacillus anthracis as a bioterrorism agent makes anthrax an important global issue. The aim of the present study was to review human anthrax in Turkey during the last decade. Human anthrax cases recorded from 1990 to 2005 were obtained from the website of the Turkish Ministry of Health, and those recorded between 1995 and 2005 were plotted on a map of Turkey. Papers on anthrax published from Turkey between 1990 and 2007 were collected and reviewed. Most cases were recorded from the central and eastern parts of Turkey. Three of the reports appeared in international journals prior to 1990, 10 reports appeared in the 1990s, and 24 reports appeared after the anthrax events of 2001 in the United States of America. These reports included 926 cases, 426 of which could be reviewed: 413 (96.9%) cases of cutaneous anthrax, 8 (1.9%) cases of gastrointestinal anthrax, and 5 (1.2%) cases of anthrax meningitis. Of all the affected patients, 95.2% had contact with contaminated materials. All human origin isolates were sensitive to penicillin and did not produce beta-lactamase. Most of the patients (88.7%) had received penicillin G. Total mortality was 2.8%. Anthrax is an endemic disease in Turkey, and acquisition of infection is generally through contact with ill or dying animals or animal products. Sheep and cattle are generally involved. Most clinical disease in humans is cutaneous anthrax, although other clinical forms are seen and have a greater mortality. Penicillin remains the drug of choice in treating the disease. Controlling anthrax in humans depends on controlling the infection in animals.

    ABSTRACT: Current progress in the development of vaccines has decreased the incidence of fatal and non-fatal infections and increased longevity. However, new technologies need to be developed to combat an emerging generation of infectious diseases. DNA vaccination has been demonstrated to have great potential for use against a wide variety of diseases. Alone, this vaccine technology does not generate a significant immune response for vaccination, but combined with delivery by electroporation (EP), can enhance plasmid expression and immunity against the expressed antigen. Most EP systems, while effective, can be invasive and painful making them less desirable for use in vaccination. Our lab recently developed a non-invasive electrode known as the multi-electrode array (MEA), which lies flat on the surface of the skin without penetrating the tissue. This study evaluated the use of the MEA for the development of DNA vaccines. We assessed the appropriate delivery conditions for gene expression and the development of humoral immunity. We used both B. anthracis and HBV as infectious models for our experiments. Our results indicated that the MEA can enhance gene expression in a mouse model with minimal to no tissue damage. Optimal delivery conditions, based on generation of antibodies, were determined to be 125-175V/cm and 150ms with 200ug and a prime boost protocol administered on Day 0 and 14. Under these conditions, end-point titers of 20,000-25,000 were generated. Neutralizing antibodies were noted in 40-60% of animals. Additionally, we utilized a guinea pig model to assess the translation potential of this electrode. The plasmid encoding HBsAg, pHBsAg, was delivered intradermally with the MEA to guinea pig skin. The results show increased protein expression resulting from plasmid delivery using the MEA as compared to injection alone. Within 48 hours of treatment, there was an influx of cellular infiltrate in the experimental groups. Humoral responses were also increased significantly in both duration and intensity as compared to the injection only groups. Results from both experimental models demonstrate that protective levels of humoral immunity can be generated and that this electrode should translate well to the clinic.
