An international inter-laboratory study to compare digital PCR with ISO standardized qPCR assays for the detection of norovirus GI and GII in oyster tissue.

An optimized digital RT-PCR (RT-dPCR) assay for the detection of human norovirus GI and GII RNA was compared with ISO 15216-conform quantitative real-time RT-PCR (RT-qPCR) assays in an interlaboratory study (ILS) among eight laboratories. A duplex GI/GII RT-dPCR assay, based on the ISO 15216-oligonucleotides, was used on a Bio-Rad QX200 platform by six laboratories. Adapted assays for Qiagen Qiacuity or ThermoFisher QuantStudio 3D were used by one laboratory each.

Congenital hypotrichosis in a Simmental cross heifer.

Background: Congenital hypotrichosis is defined as a less than normal amount of hair, obvious at birth or in the first weeks of life. Causes are nongenetic or genetic.

Objectives: To describe the clinical presentation and histological features of a novel form of hypotrichosis in a heifer.

Molecular and genetic characteristics of small ruminant lentiviruses in Slovenia.

Small ruminant lentiviruses (SRLV) are spread throughout the world, including Slovenia, where the first evidence of caprine arthritis encephalitis virus (CAEV) infection was found in 1996. This study was conducted to investigate the molecular and genetic characteristics of SRLV infection in Slovenia in order to classify our strains in relation to other known SRLV strains worldwide as well as to establish molecular techniques in concordance with serology. In this study, 340 goats and sheep were tested.

Study of the genetic variability of porcine circovirus type 2 detected in Serbia and Slovenia.

Recent variants of porcine circovirus type 2 (PCV2) were obtained from tissues of domestic pigs with porcine circovirus associated disease and from randomly selected wild boar samples from Serbia and Slovenia. A 450-base-pair nucleotide sequence was obtained by PCR from the ORF2. The derived nucleotide and amino acid sequences were aligned and compared to the corresponding region of closely related PCV2 sequences determined in previous years and retrieved from the GenBank.

Management of lingually displaced mandibular canine teeth in five bull terrier dogs.

Lingually displaced mandibular canine teeth (304, 404) were treated by applying inclined planes in five bull terrier dogs aged 10-19 months. The inclined planes produced interrupted tipping forces and were left in place for 3 weeks. The orthodontic movement technique successfully resolved the malocclusions.
