The truncated E Protein of DTMUV Provide Protection in Young Ducks

Publication date: Available online 13 November 2019Source: Veterinary MicrobiologyAuthor(s): Linlin Li, Yun Zhang, Jiawen Dong, Junqing Zhang, Chunhong Zhang, Minhua Sun, Yongchang CaoAbstractDuck Tembusu virus (DTMUV) is a major pathogen of duck industry in China. In the current study, we generated different constructs containing envelope (E) protein, pre-membrane-envelope (prM-E) protein, and C-terminally truncated E protein of the DTMUV. The constructed proteins could induce specific antibody responses in young ducks. When ducklings were immunized with the constructed proteins, they were 100% protected against DTMUV infection. Furthermore, the fluorescent signal of the truncated E protein was stronger than other constructed proteins, when Bac-to-Bac baculovirus expression system was applied. Our data demonstrated that the truncated E protein used in the current study could be applied as a potential vaccine candidate to control DTMUV infection in young ducks.

In this study, 48 PCV2 strains were isolated in China between 2016 and 2018 and the genetic diversity of these PCV2 isolates was determined. Results showed that these PCV2 isolates were classified into genotypes PCV2a (4 of 48), PCV2b (13 of 48) and PCV2d (31 of 48). Among them, 54.5% isolated in 2016, 65.2% isolated in 2017 and 71.4% isolated in 2018 belonged to PCV2d. It indicated that the prevalence of PCV2d genotype increased. All strains shared 93.4%-100% nucleotide sequence identity for the whole genome. Results of the analysis using RDP 4.0 molecular recombination software showed there were no recombinant events amo...

ConclusionsThese data suggest that a combined innate and adaptive immunotherapeutic approach can be effective against immunologically cold syngeneic murine neuroblastoma. Further testing is needed to determine how these concepts might translate into development of more effective immunotherapeutic approaches for the treatment of clinically high-risk neuroblastoma.

​Fingertip injuries and amputations are common in the emergency department, often occurring on weekends when consultants are not available. Some experienced physicians may consider rongeuring distal tuft amputation injuries, but simple closure and expert consultation for more difficult cases are suggested.A fingertip amputation within zone III involving total amputation of the distal tip, fingernail, matrix, and tuft. Photos by M.

This study aimed to analyze the effect and mechanism of immunization of oral KISS1 DNA vaccine on the proliferation of goat testicular Leydig cells. Ten 8-week-old male goats were randomly divided into KISS1 DNA vaccine and control groups for immunization (five goats each group). These goats were sacrificed at 8 weeks after primary immunization, and the tissue samples of hypothalamus, pituitary, and testis and Leydig cell samples were collected for RT-PCR and CCK8 assay. Immunization with the oral KISS1 DNA vaccine effectively inhibited the proliferation of Leydig cells, the expression of hypothalamus KISS1, GPR54, ...

We report the longitudinal profile of ILTV genome copies (GC) in poultry house dust collected on settle plates following vaccination of 8 flocks of commercial meat chickens on four farms. ILTV GC was enumerated using quantitative real-time polymerase chain reaction (qPCR). There was considerable variation between flocks in the levels of ILTV GC detected post vaccination and this variation was significantly associated with vaccine take measured in individual birds in a companion study. There was no effect of sampling location on ILTV GC in dust but the amount of dust collected was greater in locations closer the exhaust fan...
