Development of a multiplex qRT-PCR assay for detection of classical swine fever virus, African swine fever virus, and .

Classical swine fever virus (CSFV), African swine fever virus (ASFV), and () remain endemic in many parts of China. Co-infections make distinguishing their clinical symptoms and pathological changes difficult. This study developed a multiplex real-time quantitative reverse transcription polymerase chain reaction (multiplex qRT-PCR) that can simultaneously detect CSFV, ASFV, and .

A Novel Enzootic Nasal Tumor Virus Circulating in Goats from Southern China.

Enzootic nasal tumor virus (ENTV) has two types, ENTV-1 in sheep and ENTV-2 in goats, respectively. In China, the incidence of ENTV-2 related diseases has increased year by year. In this study, we reported an outbreak of ENTV-2 in a commercial goat farm in Qingyuan city, Guangdong province, southern China.

Genome Sequence of a Novel Porcine Circovirus Type 2 Strain That Reemerged in Southern China.

Here, we describe a novel porcine circovirus type 2 (PCV2) variant (GD2014) found in the Guangdong province, southern China. Its complete genome is 1,766 nucleotides and contained a 708-nucleotide open reading frame 2 (ORF2). Sequence analysis suggested that GD2014 is closest to JS2015 originating from the Jiangsu province of China and belongs to the PCV2d genotype.

Effect of dental plaque control on infection of Helicobacter pylori in gastric mucosa.

Background: Data on the role of dental plaque in the transmission of Helicobactor pylori have varied. Furthermore, there has been few reports on the relationship between dental plaque control and H. pylori infection of gastric mucosa.

[Establishment of animal model for research of first molar mesial movement in rat].

Purpose: To establish an animal model for research of first molar mesial movement in rat.

Methods: Forty 7-weeks-old SPF female Wistar rats were chosen in this experiment, which were divided into two groups. In each group, the two central incisors were used as anchorage to move the maxillary first molars mesially.

Effect of dental plaque control on infection of Helicobacter pylori in gastric mucosa.

Background: Data on the role of dental plaque in the transmission of Helicobacter pylori have varied. Furthermore, there has been few reports on the relationship between dental plaque control and H. pylori infection of gastric mucosa.

[Effects on Helicobacter pylori reinfection in gastric mucosa by two oral plaque control methods].

Objective: To investigate the reinfection rate of Helicobacter pylori (H. pylori) in gastric mucosa by two measures of oral plaque control on patients, and to demonstrate the necessity and better method of plaque control on those patients.

Methods: 148 patients suffered gastritis or gastroduodenal ulcer were assigned into test group 1 (54 patients), test group 2 (55 patients) and control group (39 patients).
