An outbreak of bacteremia at a farm in Hainan, China.

Aim: To describe the histopathology and etiology of an outbreak of respiratory disease at a farm in Hainan, China.

Methods And Results: The etiology was confirmed by gross examination and microscopic analysis. The bacterial isolates from blood and internal organs were identified by biochemical analysis and 16S rRNA gene sequencing.

Novel Streptococcus uberis sequence types causing bovine subclinical mastitis in Hainan, China.

Aim: To determine the molecular epidemiology, genotypes and phenotypes of the major species of Streptococcus associated with bovine subclinical mastitis in Hainan, China.

Methods And Results: In total, 150 subclinical mastitis milk samples were collected from two large dairy farms in Hainan. On the basis of biochemical tests and 16S rDNA sequencing, 39 samples were Streptococcus positive and the most frequently isolated species was Streptococcus uberis (n = 29, 74.

Interferon-λ1 suppresses invasion and enhances autophagy in human osteosarcoma cell.

Objective: The purpose of the present study was to determine whether type III IFN can modulate the autophagic response in human osteosarcoma cell.

Methods: Human osteosarcoma cell were treated with Interferon-λ1. We investigated that Interferon-λ1 could inhibit the invasive ability of osteosarcoma cells by Matrigel invasion assay.

Autophagy activated by Toxoplasma gondii infection in turn facilitates Toxoplasma gondii proliferation.

Autophagy was found to play an antimicrobial or antiparasitic role in the activation of host cells to defend against intracellular pathogens, at the same time, pathogens could compete with host cell and take advantage of autophagy to provide access for its proliferation, but there are few articles for studying the outcome of this competition between host cell and pathogens. Therefore, the aim of our study was to investigate the relationship between autophagy activated by Toxoplasma gondii (T. gondii) and proliferation of T.

[The relationship among congenital Toxoplasma gondii infection, pregnancy outcome and T lymphocyte subsets in umbilical cord blood].

Objective: To reveal the relationship among congenital Toxoplasma gondii (T. gondii) infection, T lymphocyte cell subsets in umbilical cord blood and pregnancy outcome.

Methods: 784 umbilical cord blood samples were collected and information of pregnancy outcomes was collected in a hospital of Hefei city, Anhui province during March 2009 to May 2010.
