Hepatitis E virus infection in pregnant women, Argentina.

Background: Hepatitis E virus (HEV) infection is an important cause of acute hepatitis worldwide. In pregnant women, HEV can cause more severe symptoms, with high rates of fatal hepatic failure in endemic countries. However, HEV prevalence and circulation among pregnant women from South America is almost unknown.

Detection of human herpesvirus 6 (HHV-6) and human herpesvirus 7 (HHV-7) DNA in endocervical samples from a positive and negative HPV woman of Córdoba, Argentina.

Aims: The purpose of the present study was to elucidate the presence of human herpesvirus 6A (HHV-6A), HHV-6B and HHV-7 in samples of the uterine cervix through detection of viral DNA. We analysed normal tissues, samples with low-grade squamous intraepithelial lesions (LSILs) and high-grade squamous intraepithelial lesions (HSILs). We correlated the presence of HHV-6 and HHV-7 with the finding of human papillomavirus (HPV) in mucosal samples.

Molecular characterization of Chlamydia pneumoniae in animals and humans from Argentina: Genetic characterization of Chlamydia pneumoniae.

In this study, genetic diversity of Chlamydia pneumoniae was investigated and the relationships between sequences amplified of different sources, clinical conditions and geographical regions of central Argentina were established. Samples amplified were similar to human C. pneumoniae patterns and show the high clonality of the population.

Detection of the ompA gene of Chlamydophila pecorum in captive birds in Argentina.

Bacteria belonging to the family Chlamydiaceae cause a broad spectrum of diseases in a wide range of hosts, including humans, other mammals and birds. However, very little is known about chlamydial infections in birds in our region. In the present study, we examined 28 clinically normal birds in illegal captivity that were confiscated in the province of C6rdoba, Argentina.

Genotyping of C. psittaci in central area of Argentina.

In central area of Argentina, the epidemiologic and molecular characteristics of Chlamydophila psittaci infections are still unknown. Nested polymerase chain reaction of domains II, III, and IV of the omp A gene was used to detect Chlamydophila in 43 pharyngeal swab samples from patients with suspected human psittacosis (2010-2011); 9 (21%) of them yielded positive results. Molecular typing was performed by direct sequencing demonstrating the presence of C.
