Histomonosis (blackhead disease): a re-emerging disease in turkeys and chickens.

Histomonosis (blackhead disease): a re-emerging disease in turkeys and chickens. Avian Pathol. 2019 Aug 08;:1-12 Authors: Liebhart D, Hess M Abstract Histomonosis or blackhead disease is a well-known disease in turkeys that can cause high mortality but outbreaks with lower losses are also observed. The disease is less fatal in chickens but economically important due to reduced performance and its co-appearance with colibacillosis. The lack of specific prophylactic and therapeutic interventions led to a re-emergence of the disease in recent years, mainly in turkeys, free-range layers and chicken parent stock.

To better understand public health implications of waterfowl as reservoirs for zoonotic sources of Campylobacter in recreational waters, we developed a Gallus gallus (chick) model of infection to assess the pathogenicity of environmental isolates of Campylobacter. This method involved exposure of 1-day-old chicks through ingestion of water, the natural route of infection. Viable Campylobacter from laboratory-infected animals were monitored by using a modified non-invasive sampling of fresh chick excreta followed by a passive polycarbonate-filter migration culture assay. The method was used to evaluate the infectivities of ...

A recent study in this journal compared codon usage among NA subtypes (N1, N2, N6, and N8)  of H5Nx highly pathogenic avian influenza A viruses (HPAIVs) and suggested that codon usage in N1 subtype is better adapted to its host than the epidemic NA subtypes (N6 and N8), which had fewer number of human cases compared to the N1 subtype.1 To date, there are 18 known HA subtypes (H1-H18) and 11 known NA subtypes (N1-N11)2. However, only N1 and N2 subtypes have been reported to cause pandemics (H1N1 for the 1918 and 2009 pandemics; H2N2 for the 1957 pandemic; and H3N2 for the 1968 pandemic) or seasonal outbreaks in humans3.

In this study, we developed a reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay for the diagnosis of parrot bornavirus 4 (PaBV-4), a dominant ABV genotype. Using this assay, we successfully detected PaBV-4 RNA in cell cultures, brain tissues, and feces. We also developed methods for simple RNA extraction and visual detection without electrophoresis. The sensitivity of the newly established RT-LAMP assay was 100-fold higher than that of the real-time PCR (RT-qPCR) assay. Accordingly, the RT-LAMP assay developed in this study is suitable for the rapid and sensitive diagnosis of PaBV-4 without speci...

Abstract Salmonella infections in poultry farms are overlooked in many African countries; yet these infections are mostly zoonotic with impact on both poultry industry and public health. Considering the impact of Salmonella in laying hens, and the role of laying hens as a source of Salmonella outbreak in human, knowledge of the status of Salmonella on laying hen farms as well as the factors influencing the presence of Salmonella is important. In a cross sectional study, cloacal swabs were collected from 270 commercial laying hens on 27 farms located in Menoua Division. These samples were cultured on standard media...

Frequent disease outbreaks are not uncommon even in vaccinates despite routine vaccination and, in this regards, viruses of diverse genotypes originating from natural reservoirs (migratory waterfowls) play an important role in a disease endemic setting. Though genomic characterizati...

DovasAbstractWest Nile virus (WNV) is an arbovirus causing neuroinvasive disease to humans and equines. Since 2004, lineage 2 WNV strains have been identified in Europe and have been implicated in severe outbreaks, with that of 2018 exceeding the total number from the previous seven years. The aim of this study was to explore the evolutionary process that shapes the genetic diversity of lineage 2 WNV strains (belonging to the Central European/Hungarian subc...

NLM Informatics and Data Science Lecture Series Genomics-informed surveillance is now recognized as an important extension to the monitoring of rapidly evolving pathogens. Next generation sequencing has the ability to produce large amounts of data for tracking viruses of public health importance. Biomedical informatics approaches are able to facilitate the translation of these data into information for public health surveillance. Thus, epidemiologists can identify new outbreaks or monitor the course of a known epidemic by leveraging pathogen sequences (and corresponding metadata) generated from the clinical specimens of si...

This report describes an outbreak of erysipelas in a colony of captive Humboldt penguins (Spheniscus humboldti). The only previously reported case in a related species was of an individual little blue penguin (Eudyptula minor). Five Humboldt penguins in a mixed colony displayed non-specific signs of illness, including lethargy, inappetence and regurgitation after movement for exhibit upgrading. There was no improvement after 5 days of treatment with oral enrofloxacin (10 mg/kg q24h). Four Humboldt penguins, including two that were not part of the original five displaying signs of illness, died during this outbreak and...

Armando Isibasi Constantino López-Macías The clinical effects and immunological response to the influenza vaccine in women who later become pregnant remain to be thoroughly studied. Here, we report the medical outcomes of 40 women volunteers who became pregnant after vaccination with an experimental virus-like particle (VLP) vaccine against pandemic influenza A(H1N1)2009 (influenza A(H1N1)pdm09) and their infants. When included in the VLP vaccine trial, none of the women were pregnant and were randomly assigned to one of the following groups: (1) placebo, (2) 15 μg dose of VLP vaccine, or (3) ...
