Population studies have recently revealed that some of the major clonal lineages of Toxoplasma gondii dominate in different geographical areas. The lineage of Type II and III are widespread in all continents and dominate in Europe, Africa and North America. In addition, type 12 lineage is the most common type of wildlife in North America, Africa 1 and 3 is one of the main species in Africa, and ToxoDB PCR-RFLP # 9 is the kind of big in China. Overall strains of T. gondii were more diverse in South America than any other region. Here, we analyzed 164 isolates of T. gondii from three Central American countries (Guatemala, Nicaragua, Costa Rica), from one country in the Caribbean (Grenada) and five countries of South America (Venezuela, Colombia, Peru, Chile, and Argentina ).
The multilocous polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) genotyping based on 11 polymorphic markers (SAG1, SAG2, alt.SAG2, SAG3, BtuB, GRA6, L358, PK1, C22-8, C29-2 and Apico) applied for 148 domestic poultry (Gallus domesticus) isolates and 16 isolates from the domestic cat (Felis catus) in Colombia; 42 genotypes were identified. Linkage disequilibrium analysis showed genetic recombination more frequently in populations of Nicaragua and Colombia, and to a lesser degree in the population of Costa Rica and Argentina. Bayesian structural analysis identified at least three groups of genetic and phylogenetic network analysis identifies four main groups. The ToxoDB PCR-RFLP # 7, Type III and II major lineages identified from Central and South America, with a high frequency of ToxoDB PCR-RFLP # 7 and Type III is closely related lineages.
direct molecular blood test for early Lyme disease can not be sensitive because of the low number of outstanding Borrelia burgdorferi DNA. To address these challenges, we have developed a strategy and genotype sensitive to detect B. burgdorferi directly from whole blood collected during the initial patient visit. This strategy increases sensitivity by using 1.25 mL of whole blood, a novel pre-enrichment of the entire specimen extracts to Borrelia multi-locus DNA prior to PCR and electrospray ionization mass spectrometry detection assay. We evaluate the blood test were collected at initial presentation of 21 patients of endemic areas who have both physician-diagnosed erythema migrans (EM) and serology two positive level either at baseline or follow-up visit after three weeks of antibiotic therapy.
Molecular genotyping of Toxoplasma gondii from Central and South America revealed high diversity within and between populations.
molecular genotyping of methicillin-resistant Staphylococcus aureus through enhanced fluorofor repetitive-sequence-PCR.
methicillin resistance in Staphylococcus aureus is a frequent cause of nosocomial infections and community acquired. Accurate, fast epidemiological typing is very important to identify the source and spread of infectious diseases and can provide detailed information about the generation of methicillin-resistant S. aureus (MRSA) strains. A high level of genetic linkage strains of MRSA have barred the use of the more conventional methods of genetic fingerprinting. A DNA fingerprinting method that exploit the rapid PCR amplification of repetitive DNA sequences in MRSA described.

Description: GM-CSF is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced in endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. The human and murine molecules are species-specific and exhibit no cross-species reactivity. Recombinant murine GM-CSF is a 14.2 kDa globular protein consisting of 125 amino acid residues.
