Retrospective study reveals the circulation of norovirus genotype GII.P21-GII.2 in Romania.

Noroviruses are the leading cause of acute gastroenteritis, causing significant economic burden globally. Infection is self-limiting, occurring as sporadic cases or producing outbreaks associated with consumption of contaminated water or food. All age groups are affected and person to person transmission is frequent.

Dobrava virus carried by the yellow-necked field mouse Apodemus flavicollis, causing hemorrhagic fever with renal syndrome in Romania.

Hemorrhagic fever with renal syndrome (HFRS) has been confirmed by serological methods during recent years in Romania. In the present study, focus-reduction neutralization tests (FRNT) confirmed Dobrava hantavirus (DOBV) as the causative agent in some HFRS cases, but could not distinguish between DOBV and Saaremaa virus (SAAV) infections in other cases. DOBV was detected by a DOBV-specific TaqMan assay in sera of nine patients out of 22 tested.

Association of Prothrombin (A20210G) and Factor V Leiden (A506G) with Recurrent Pregnancy Loss.

Background: Inherited thrombophilias are the leading cause of maternal thromboembolism and are associated with an increased risk of recurrent spontaneous abortion (second- and third-trimester fetal loss). The purpose of this study was to investigate the effects of factor V and factor II involved in reproductive failure. Recently a possible association between unexplained infertility and genetic thrombophilia gene mutations have been reported with a significant statistically association with prothrombin A20210G.

Identification of four Treponema species in subgingival samples by nested-PCR and their correlation with clinical diagnosis.

The relationship between different species of oral Treponemas and inflammation in periodontal disease progression is complex. The purpose of this study was to analyze and compare the subgingival plaque samples collected from periodontally healthy subjects and from chronic gingivitis and periodontitis patients in order to detect the presence of T. denticola, T.

Identification of Treponema denticola in subgingival samples by PCR technology and its correlation with clinical diagnosis.

Treponema denticola has been associated with gingivitis and chronic periodontitis. The aim of this study was to identify Treponema denticola in subgingival samples using PCR technology and to correlate it with clinical diagnosis of subjects. The study was carried out on seventy patients (20-84 years of age; mean age, 45.
