1. Ultrastructural viewpoints on the interaction events of Scedosporium apiospermum conidia with lung and macrophage cells
BACKGROUND Scedosporium apiospermum is a ubiquitous, emerging and multidrug-resistant fungal pathogen with still rather unknown virulence mechanisms. OBJECTIVES/METHODS The cellular basis of the in vitro interaction between fungi and host cells/tissues is the determinant factor for the development of a successful in vivo infection. Herein, we evaluated th

2. Transcriptome Analysis of Chicken Embryo Fibroblast Cell Infected with Marek’s Disease Virus of GX0101 ∆ LTR
ABSTRACT Marek’s disease (MD), a lymphoproliferative disorder of chickens caused by the MD virus (MDV), is economically significant. The resistance/susceptibility to MD is controlled by host genetics. The host response to different virus strains varies. The pathogenicity of REV-LTR deleted GX0101∆LTR MDV has been previously reported. However, the precise

3. Aptamers as a promising approach for the control of parasitic diseases
ABSTRACT Aptamers are short single-stranded RNA or DNA oligonucleotides that are capable of binding various biological targets with high affinity and specificity. Their identification initially relies on a molecular process named SELEX (Systematic Evolution of Ligands by EXponential enrichment) that has been later modified in order to improve aptamer sensiti

4. Cytological aspects of incompatible and compatible interactions between rice, wheat and the blast pathogen Pyricularia oryzae
ABSTRACT Blast, caused by the fungus Pyricularia oryzae, is an important disease affecting rice and wheat yield worldwide. This study investigated the cytological aspects of incompatible (non-host resistance) and compatible (host resistance) rice- (R_Po) and wheat- (W_Po) Pyricularia oryzae isolate interactions. Inoculations of rice and wheat with the R_Po a

5. 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

6. Metabolomics in the fight against malaria
Metabolomics uses high-resolution mass spectrometry to provide a chemical fingerprint of thousands of metabolites present in cells, tissues or body fluids. Such metabolic phenotyping has been successfully used to study various biologic processes and disease states. High-resolution metabolomics can shed new light on the intricacies of host-parasite interactio

7. Interaction between Paracoccidioides brasiliensis conidia and the coagulation system: involvement of fibrinogen
The infectious process starts with an initial contact between pathogen and host. We have previously demonstrated that Paracoccidioides brasiliensis conidia interact with plasma proteins including fibrinogen, which is considered the major component of the coagulation system. In this study, we evaluated the in vitro capacity of P. brasiliensis conidia to aggre

8. Physiological changes in wheat during development of loose smut
This study was planned to determine the dynamics of total phenolic content, polyphenol oxidase and peroxidase activities in wheat (var. Inqlab-91) infected with Ustilago tritici with the objective to investigate the role of phenolics and related enzymes in host pathogen interaction. The biochemical analysis was carried out twice, once at grain filling stage

9. 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

10. Surface-expressed enolases of Plasmodium and other pathogens
Enolase is the eighth enzyme in the glycolytic pathway, a reaction that generates ATP from phosphoenol pyruvate in cytosolic compartments. Enolase is essential, especially for organisms devoid of the Krebs cycle that depend solely on glycolysis for energy. Interestingly, enolase appears to serve a separate function in some organisms, in that it is also expor

11. Variabilidad de Puccinia sorghi en la zona maicera núcleo Argentina
Common rust caused by Puccinia sorghi is one of the endemic diseases of corn in Argentina. It appears every year with different levels of severity depending on the genotype of the host, the biotypes of the pathogen, and the environmental conditions. Estimates of grain weight losses ranged from about 3 to 8% for 10% of the total leaf area affected. P. sorghi

12. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion
