Capillaria aerophila, a trichuroid nematode causing pulmonary infections in wild and domestic carnivores, is occasionally and potentially poorly recognized in infections of humans due to clinicopathological mimicry and a lack of accurate, robust laboratory diagnostics. The present work evaluated the efficiency of a DNA-based assay amplifying a partial cytochrome c oxidase subunit 1 (cox1) gene ...

OBJECTIVE Polyomavirus-associated nephropathy (PVAN) is a major cause of graft dysfunction after kidney transplantation. Therefore, routine screening for BK polyomavirus (BKV) infection with urine cytology or quantitative PCR-based assays has been recommended. Although less expensive than quantitative tests, qualitative PCR assays are not recommended for screening based on the assumption that t...

BACKGROUND Clarithromycin is one of the most important antibiotics for Helicobacter pylori eradication. However, 5-10% of strains are reported to be resistant. It has been shown that one point mutation in the 23S rRNA gene is associated with resistance to clarithromycin. AIMS To establish a polymerase chain reaction (PCR) system which amplifies a segment of the 23S rRNA gene containing the mu...

This study aimed to verify the diversity of Culicidae species and their frequency of infection with flaviviruses and alphaviruses in Cuiabá, state of Mato Grosso, Brazil. Mosquitoes were captured with Nasci aspirators and hand net in 200 census tracts, identified alive at species level and pooled in one-20 (11,090 mosquitoes, 14 species). Female pools (n = 610) were subjected to multiplex semin...

Gurltia paralysans (order Strongylida; family Angiostrongylidae) is a metastrongyloid parasite that causes chronic meningomyelitis in domestic cats South America. The geographic distribution of G. includes rural and periurban areas Chile Argentina. However, feline gurltiosis has recently been reported other American countries, including Uruguay, Colombia, Brazil, was also Tenerife, Canary Islan...

Rearrangement of the immunoglobulin heavy chain (IgH) gene has been used as a marker of lineage and clonality in the diagnosis of B lymphoproliferative disorders. A number of PCR-based techniques have been developed to overcome the disadvantages of Southern blotting, the standard technique in detecting IgH gene rearrangement. Using an established seminested PCR technique with consensus primers ...

Figure 1. Detection of Borna disease virus (BDV)–specific nucleic acid in peripheral blood mononuclear cells (PBMC) of a man with chronic fatigue syndrome (CFS), by nested and seminested polymerase chain reaction assays. Lanes: A, BDV-negative PBMC; B, BDV-specific amplicates from PBMC of patient with CFS; M, size marker (100-bp DNA ladder). Demonstration of Borna Disease Virus Nucleic Acid in ...
