A case series of suspected cases congenital Zika syndrome in a maternity hospital Tuxtla Gutierrez, Chiapas, Mexico was assembled to assess why they were not reported and explore the hypothesis dengue antibody dependent disease. Clinical imaging records, interviews total 13 revealed that only one them laboratory confirmed because appropriate specimens collected from newborns as required by defi...

BACKGROUND The aim of the study was to test the efficacy of a novel low-abrasive air polishing powder in subgingival plaque removal at interdental sites during periodontal maintenance therapy (PMT). METHODS Using a split mouth design, subgingival plaque was removed in 23 PMT patients using a low abrasive powder using a standard air polishing unit (test) or curets (positive control). Before an...

background there is inconclusive evidence about the relationship between toothbrush wear and plaque removel. the aim of this study was to compare the effectiveness of new and 3 month-old toothbrush in the removal of dental plaque. material and methods in a randomized single blind clinical trial 63 students attended from awaz dental school. subjects were divided to three groups. plaque was score...

Enzyme-linked immunosorbent assays (ELISAs) were developed for detection of immunoglobulin G (IgG) and IgM antibodies to Venezuelan equine encephalomyelitis (VEE) virus in vaccinated and naturally infected humans. A total of 441 sera found negative for VEE antibodies by plaque reduction neutralization were examined by IgG ELISA and gave a 1.0% false-positive rate; no false-positives were found ...

BACKGROUND AND AIM: Bacterial plaque is the uppermost element in periodontal diseases. Chlorhexidine (CHX) is one of the utmost influential materials in chemical plaque control and ORTHOKIN is a toothpaste claimed to encompass CHX. Although there are various studies on efficacy of different types of CHX formulation in toothpaste, no literature has focused on the anti-plaque effects of toothpast...

Among bovine rotavirus strains, there are three G serotypes (G6, G8, and G10) and three P (VP4) serotypes (PB1, PB2, and PB3, which are defined on the basis of strains NCDV, UK, and B223, respectively). Plaque reduction neutralization assays with hyperimmune antisera disclosed two-way antigenic relationships of strain KN-4 with strain KK-3 (G10, PB3) as well as with strains NCDV (G6, PB1) and 0...

Human immunodeficiency virus type 2 (HIV-2) is less transmissible and less pathogenic compared to HIV-1 and, when matched for CD4(+) T cell count, the plasma viral load in HIV-2-infected individuals is approximately one log lower than in HIV-1-infected individuals. The explanation for these observations is elusive, but differences in virus controlling immunity generated in the two infections ma...

Fecal samples from rotavirus-infected piglets were characterized by a serotyping enzyme-linked immunosorbent assay (ELISA) by using monoclonal antibodies (MAbs) specific to human serotypes 1, 2, 3, and 4 (D. O. Matson, M. K. Estes, J. W. Burns, H. B. Greenberg, K. Taniguchi, and S. Urasawa, submitted for publication). Rotavirus in 19 of 25 specimens tested from two herds of pigs from Buenos Air...

BACKGROUND The purpose of this study was to review the literature on the effects of a mouthrinse containing essential oils (EO) on plaque and parameters of gingival inflammation. METHODS The MEDLINE and Cochrane Central Register of Controlled Trials were searched up to and including December 2006 to identify appropriate studies. The primary outcome measure was gingivitis. Secondary parameters...

Phage conversion of toxigenicity in Clostridium botulinum types C and D was accomplished by using nontoxigenic strains and phages purified from plaques. Although the morphology of the converting phages seemed to be the same, they were divided into three groups on the basis of their conversion spectrum. The first group consists of phages obtained from toxogenic strains C-Stockholm and C-468. The...
