Serosurvey of Avian metapneumovirus, Orithobacterium rhinotracheale, and Chlamydia psittaci and Their Potential Association with Avian Airsacculitis.

This study tried to unveil the potential role of Avian metapneumovirus (AMPV), Ornithobacterium rhinotracheale (ORT) and Chlamydia psittaci (CPS) in avian airsacculitis. A serological investigation of 673 breeder chickens and a case-controlled study of 430 birds were undertaken. Results showed that infection with AMPV, ORT, and CPS was highly associated with the disease. The correlation between AMPV and CPS were positively robust in both layers and broilers. Finally, we determined the co-infection with AMPV, ORT, and CPS was prevalent in the sampled poultry farms suffering from respiratory diseases and the outbreak of airsacculitis was closely related to simultaneous exposure to all three agents.

In this study, the effects of berberine on rotenone-induced neurotoxicity in SH-SY5Y cells were investigated. The results showed that berberine treatment significantly alleviated rotenone-induced decrease in the cell viability in SH-SY5Y cells. Further studies demonstrated that berberine suppressed the production of intracellular reactive oxygen species, restored the mitochondrial transmembrane potential, increased Bcl-2/Bax ratio, and decreased caspase-3 activation that induced by rotenone. Furthermore, berberine also restored the phosphorylation of Akt, which was downregulated by rotenone in SH-SY5Y cells. These results ...

Background: Two types of alleles exist within intron 3′ and exon 8 in the presenilin 1 (PS1) gene at nucleotide 16: allele 1 (A at site 16) and allele 2 (C at site 16), and three genotypes (1/1, 1/2, and 2/2) are formed with a combination of these alleles. The present study aims to investigate the association between the intronic polymorphism of PS1 gene and the occurrence of sporadic Alzheimer’s disease in a northern Chinese population. Materials and methods: The genotype and allele frequencies of PS1 gene were compared for 90 sporadic Alzheimer’s disease patients and 90 healthy controls. The intron...

ConclusionAn ST2 LZD- and meticillin-resistant clone was found in the ICU and also in wards with low consumption of LZD. This highlights the need to implement and maintain infection control measures as well as antimicrobial stewardship programmes in all hospital units in order to preserve the efficacy of LZD.

Abstract Chlamydia psittaci (C. psittaci) is prevalent in chicken broiler production. However, the role of C. psittaci in the respiratory disease complex needs to be clarified. It was our purpose to identify the time point when a C. psittaci infection appeared on a broiler farm and to examine the presence of other respiratory pathogens at that time. We focused on the 'major' respiratory pathogens occurring in Belgian broilers namely Infectious bronchitis virus (IBV), Avian metapneumovirus (aMPV), Ornithobacterium rhinotracheale (O. rhinotracheale), Mycoplasma gallisepticum (M. gallisepticum) and Mycoplasma synovia...
