Publication date: Available online 11 October 2019Source: Saudi Journal of Biological SciencesAuthor(s): Rahat Andleeb, Asma Ashraf, Saima Muzammil, Shabana Naz, Farkhanda Asad, Tayyaba Ali, Rida Rafi, K.A. Al-Ghanim, F. Al-Misned, Z. Ahmed, Shahid MahboobAbstractThe study was implemented to actuate the qualitative and quantitative phyto constituents of Iresine herbstii extracts and its antiviral efficacy against avian ND virus. Among four tested solvents, the ethanolic extract of Iresine herbstii revealed the presence of highest quantity of all tested phytochemicals while petroleum ether extract showed the least. Folin-Ciocalteu method assessed the range of TPC extended from 81.01 ± 0.67 to 126.35 ± 0.45 µg GAE/mg. Acetonic extract showed the highest amount among all extracts and petroleum ether possessed the lower quantity. TFC ranged from 54.37 ± 0.45 to 88.12 ± 0.26 µg QE/mg followed by colorimetric method. From all extract ethanolic extract showed highest quantity and petroleum ether revealed the lower. HPLC analysis of ethanolic extract of I. herbstii confesses the presence six bioactive components by using the HP5-MS column. To check the antiviral potential of plants, different prepared treatments of plant extract and live virus were inoculated at 9 days old SPF embryonated chicken eggs. Results exposed that all plant extracts produce antiviral activity against NDV in ovo according to their potential and phytochemical profile. Th...

Linton Koray Ergünay We obtained a Jingmen tick virus (JMTV) isolate, following inoculation of a tick pool with detectable Crimean-Congo hemorrhagic fever virus (CCHFV) RNA. We subsequently screened 7223 ticks, representing 15 species in five genera, collected from various regions in Anatolia and eastern Thrace, Turkey. Moreover, we tested specimens from various patient cohorts (n = 103), and canine (n = 60), bovine (n = 20) and avian specimens (n = 65). JMTV nucleic acids were detected in 3.9% of the tick pools, including those from several tick species from the genera Rhipicephalus and Haemaphysalis, and Hyalo...

Razafimandimbison, Kent Kainulainen, Bruno Senterre, Charles Morel, Catarina RydinAbstractThe granitic islands of the Seychelles harbor about 268 native angiosperm species, with 28% being endemics there. The Seychelles biota contains a mix of ancient taxa with Gondwanan origins and young taxa that arrived there via dispersals. We investigate the phylogenetic position of an enigmatic, critically endangered, Seychellean endemic of the coffee family (Rubiaceae), Psathura/Psychotria sechellarum, and assess whet...

Authors: Kim HC, Hong EJ, Ryu SY, Park J, Yu DH, Chae JS, Choi KS, Sim C, Park BK Abstract Avian trematodes, Urogonimus turdi (Digenea: Leucochloridiidae), were collected from the intestine of wild birds, Zoothera aurea, 2013-2017 in the Daejeon Metropolitan City, Korea. The body was ellipsoidal, attenuated and/or round ends, 1,987-2,120 long and 819-831 µm wide. The oral sucker was subterminal, rounded anteriorly, and 308- 425×351-432 µm in size; the prepharynx and esophagus were almost lacking; pharynx was well-developed, 142- 179×78-170 µm in size; intestine narrow, bifurcating just...

o Kawaoka Viral neuraminidase inhibitors show limited efficacy in mice infected with H7N9 influenza A viruses isolated from humans. Although baloxavir marboxil protected mice from lethal challenge infection with a low pathogenic avian influenza H7N9 virus isolated from a human, its efficacy in mice infected with a recent highly pathogenic version of H7N9 human isolates is unknown. Here, we examined the efficacy of baloxavir marboxil in mice infected with a highly pathogenic human H7N9 virus, A/Guangdong/17SF003/2016. Treatment of infected mice with a single 1.5 mg/kg dose of baloxavir marboxil protected mice from the h...

Publication date: January 2020Source: Molecular Immunology, Volume 117Author(s): Dejian Liu, Huijun Zheng, Yaqian Li, Peng Zhou, Hui Jin, Rui LuoAbstractJanus kinase 1 (JAK1) is a member of JAK family of non-receptor protein tyrosine kinases that plays critical roles in transducing cytokine signals via JAK-signal transducer and activator of transcription (STAT) signaling pathway. The importance of JAK1 in innate immunity has been well-studied in mammals and fish, yet in avian remains largely unknown. Here, we cloned the full-length of the duck JAK1 (duJAK1) gene for the first time. DuJAK1 encoded a protein of 1152 amino ac...

Typhimurium, ST) is one of the most important serovars of the genus Salmonella in human and animals. Because of its intracellular tropism, monocytes/macrophages are pivotal in killing of Salmonella serovars; they are also responsible for transporting of ST to extra-intestinal organs. To investigate the effect of the ST on the functions of avian innate immune cells, almost homogeneous enriched monoc...

However, the proximate mechanisms underlying species-specific learned behaviors remain poorly understood. Songbirds acquire species-specific songs through learning, which is hypothesized to depend on species-specific patter ns of gene expression in functionally specialized brain regions for vocal learning and production, called song nuclei. Here, we leveraged two closely related songbird species, zebra...
