1. Media preferences, micro-morphometric analysis, and cardinal growth temperature determination for Phytophthora infestans sensu lato isolated from different hosts in Colombia
Resumo Durante os últimos anos Phytophthora infestans sensu lato causou epidemias na Colômbia em lavouras de frutos andinos, como Solanum quitoense e Solanum betaceum. Estabelecimento de procedimentos experimentais novos ou modificados para estudar este patógeno é um assunto obrigatório para os cientistas. Doze isolados de Phytophthora spp. obtidos de

2. Micronutrients: Speculation on Inborn Errors, Nutrigenomics, Evolution, the Microbiome, and Nutritional Immunity
Abstract Many micronutrients or cofactors derived from micronutrients are highly reactive, hence their role in catalysis of reactions by enzymes. The concentration of cofactors has to be kept low to avoid unwanted reactions while allowing them to bind to the (apo)enzymes that need them. A new disorder causing B6-responsive epilepsy (proline synthetase cotran

3. Challenging Mycobacterium tuberculosi s dormancy mechanisms and their immunodiagnostic potential
ABSTRACT Mycobacterium tuberculosis is the etiologic agent of tuberculosis, one of the world's greatest cause of morbidity and mortality due to infectious disease. Many evolutionary mechanisms have contributed to its high level of adaptation as a host pathogen. Prior to become dormant, a group of about 50 genes related to metabolic changes are transcribed by

4. Analysis of the chemical components of hydatid fluid from Echinococcus granulosus
Introduction The aim of this study was to explore the environment of Echinococcus granulosus (E. granulosus) protoscolices and their relationship with their host. Methods Proteins from the hydatid-cyst fluid (HCF) from E. granulosus were identified by proteomics. An inductively coupled plasma atomic emission spectrometer (ICP-AES) was used to determine

5. In vitro expression and antiserum production against the movement protein of Citrus leprosis virus C (CiLV-C)
Citrus leprosis, caused by Citrus leprosis virus C (CiLV-C), is currently considered the most important viral disease in the Brazilian citrus industry due to the high costs required for the chemical control of its vector, the mite Brevipalpus phoenicis. The pathogen induces a non-systemic infection and the disease is characterized by the appearance of locali

6. Localização genômica e subcelular dos membros da família de fosfatidilinositol quinases em Trypanosoma cruzi / Genomic and subcellular localization of the members of phosphatidylinositol kinase family in Trypanosoma cruzi
The identification of signaling molecules and the elucidation of signal transduction processes of Trypanosoma cruzi are required for understanding the host-parasite interaction and physiological processes of the parasite. However, little is yet known about signal transduction and signaling pathways that occur in the parasite, since most efforts focused on si

7. Estudo de amostras de Staphylococcus spp isolados de infecÃÃo nosocomial da cidade de Recife, Pernambuco, Brasil / Study of samples of Staphylococcus spp isolated from nosocomial infection in the city of Recife, Pernambuco, Brazil
Staphylococcus, although present in the microflora of human skin and mucosa, behaves as an opportunistic pathogen responsible for infectious complications, especially after the implantation of prosthetic devices. Furthermore, it has an extraordinary ability to acquire resistance to antimicrobials. Nowadays, methicillin-resistant Staphylococcus (MRS) are wide

8. Detecção do vírus da leprose dos citros nos tecidos da planta infectada e do ácaro vetor Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae) / Detection of Citrus leprosis virus C (CiLV-C) in the tissues of infected plants and of mite vector Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae)
Citrus leprosis is one of the most important diseases in the Brazilian citrus production due to the wide occurrence in orchards and also to the high costs involved in the chemical control of the mite vector. The disease affects the plant production and longevity and it is characterized by localized chlorotic and/or necrotic spots on the leaves, stems and fru

9. EFEITO MODULATÓRIO DA COINFECÇÃO PELO Mycobacterium bovis NA RESPOSTA IMUNOLÓGICA DE CAMUNDONGOS INFECTADOS COM Strongyloides venezuelensis
The intestinal parasites are a major medical-health problem, in view of the large number of people involved and the numerous organizational changes which may result in the host. Infections caused by Strongyloides venezuelensis have a local immune response in both lungs as in the intestine, predominantly from the Th2 type, characterized by the production of c

10. Atividade da superoxido dismutase, catalase, peroxidases e acumulo de H2O2 associados a infecção de um Carlavirus em soja e um Potyvirus no feijoeiro / Activity of superoxide dismutase, catalase, peroxidase and accumulation of H2O2 associated with the infection of a Carlavirus in soybean and a Potyvirus in bean
Plants defend themselves from attacks of bacteria, fungi, viruses, invertebrate and other plants. Oxidative stress is a kind of physiological response of the plant related to defense mechanisms after recognition the pathogen, which may result in disease symptoms depending on host sensitivity. In this work, plants of two varieties of soybean infected by Cowpe

11. Correlation between Helicobacter pylori infection, gastric diseases and life habits among patients treated at a university hospital in Southeast Brazil
Helicobacter pylori is considered a significant agent in the development of various gastric diseases. However, the diseases caused by this bacterium are known as being multi-factorial, with the genotype, immune system and life habits of the host playing important roles in the establishment of the clinical outcome. Also, H. pylori exhibit a high degree of gen

12. Epidemiologia da vassoura-de-bruxa (Crinipellis perniciosa (STAHEL) Singer) em cacaueiros enxertados em Uruçuca, BA. / Epidemiology of witches broom (Crinipellis perniciosa (STAHEL) Singer) on grafted cocoa in Uruçuca, BA.
A vassoura-de-bruxa é a doença mais importante da cultura do cacaueiro, nos países onde ela ocorre. Em 1989 foi constatada pela primeira vez a presença do patógeno causador dessa doença na principal região produtora do Brasil. A falta de medidas de controle eficientes resultou, nos últimos anos, em menor produção, mudanças no uso da terra, venda d
