13. Humoral and cellular immune response of mice challenged with Yersinia pestis antigenic preparations
ABSTRACT Objectives: The plague, which is an infectious disease caused by Yersinia pestis, still threatens many populations in several countries. The worldwide increase in human plague cases and the potential use of the bacteria as a biological weapon reinforce the need to study the immunity that is induced by potential vaccine candidates. To determine the

14. Facial botryomycosis-like pyoderma in an HIV-infected patient: remission after initiation of darunavir and raltegravir
Abstract Botryomycosis is an uncommon, chronic, suppurative, bacterial infection that primarily affects the skin and subcutaneous tissues. It has long been associated with defects of cellular immunity. We report a 28-year-old woman who presented with a chronic, ulcerated lesion with draining sinuses in the right malar region. Predisposing factors were HIV in

15. The immunogenicity and anti-tumor effects of a lung cancer DNA vaccine harboring a MUC-1 and GM-CSF fusion gene
ABSTRACT DNA vaccines have been shown to be an effective approach to induce antigen-specific cellular and humoral immunity. However, the inability of DNA vaccines to elicit strong immune responses in clinical trials limits the application of DNA vaccines. Here, we developed a new DNA vaccine based on MUC1, which has been suggested as a potential target for l

16. Infectious Bursal Disease: Pathogenicity and Immunogenicity of Vaccines
ABSTRACT The Infectious Bursal Disease (IBD) is a contagious viral disease that affects young chickens and may cause high morbidity and mortality. As the virus is very resistant to the environment, vaccination is required in case of high infection pressure. Due to variations in the virulence degree of the vaccines available to control IBD, this study aimed a

17. Campylobacter Jejuni Increases Transcribed Il-1 B and Causes Morphometric Changes in the Ileal Enterocytes of Chickens
Abstract Campylobacteriosis is a worldwide foodborne zoonosis disease caused by Campylobacter jejuni. This microorganism is considered a commensal bacterium in chicken hosts. C. jejuni produces epithelial cell modifications and induces a cytokine gene transcription innate immunity repertoire. In the present study, we describe the invasiveness, morphological

18. Update on cutaneous tuberculosis
Tuberculosis continues to draw special attention from health care professionals and society in general. Cutaneous tuberculosis is an infection caused by M. tuberculosis complex, M. bovis and bacillus Calmette-Guérin. Depending on individual immunity, environmental factors and the type of inoculum, it may present varied clinical and evolutionary aspects. Pat

19. Live bacterial vaccine vectors: An overview
Genetically attenuated microorganisms, pathogens, and some commensal bacteria can be engineered to deliver recombinant heterologous antigens to stimulate the host immune system, while still offering good levels of safety. A key feature of these live vectors is their capacity to stimulate mucosal as well as humoral and/or cellular systemic immunity. This enab

20. Chronic mucocutaneous candidiasis: a case with exuberant cutaneous horns in nipples
Chronic mucocutaneous candidiasis is a rare disorder characterized by persistent and recurrent infections by Candida due to changes in cellular immunity and may be associated with autoimmune endocrine disorders. It is refractory to the usual antifungal treatments, which merely control it with imidazole derivatives. This reports the case of a 50-year-old fema

21. Normal lymphocyte immunophenotype in an elderly population
OBJECTIVE: The aim of this work was to evaluate the lymphocyte immunophenotype in an elderly population.METHODS: This study enrolled 35 over 60-year-old volunteers and a control group composed of 35 young adults. The study included elderly without diseases that might affect the functioning of the immune system. These individuals were consulted by doctors and

22. Oxidative stress and cellular immunity in patients with recurrent aphthous ulcers
Recurrent aphthous ulcer (RAU) is an inflammatory condition of the oral mucosa characterized by painful, well-circumscribed, single or multiple round or ovoid ulcerations. The exact etiologic factor(s) of these ulcerations are not yet understood. The objective of this study was to evaluate inflammatory processes and free radical metabolism of 25 patients wit

23. Interleukin-12 gene adjuvant increases the immunogenicity of virus-like particles of human papillomavirus type 16 regional variant strain
Objectives: To analyze the immunogenicity of virus-like particles (VLP) of human papillomavirus type 16 (HPV16) isolated in East China and the adjuvant potential of interleukin-12 (IL-12). Methods: The variant HPV16 L1VLP expressed in sf9 insect cells were purified with cesium chloride gradient centrifugation. BALB/c mice were vaccinated with VLP (L1N), V

24. Vaccines for preventing herpes zoster in older adults
BACKGROUND:Herpes zoster or, as it is commonly called, 'shingles' is a neurocutaneous disease characterised by the reactivation of varicella zoster virus (VZV), the virus that causes chickenpox, which is latent in the dorsal spinal ganglia when immunity to VZV declines. It is an extremely painful condition which can often last for many weeks or months, impai
