Comparison of the protective antigen variabilities of prevalent Newcastle disease viruses in response to homologous/heterologous genotype vaccines

open access: yesPoultry Science, 2021
: The genotype VII Newcastle disease virus (NDV) vaccine has begun to replace the traditional genotype II NDV vaccine and is widely used in the commercial poultry of China.

First Oral Vaccination of Eurasian Wild Boar Against African Swine Fever Virus Genotype II

open access: yesFrontiers in Veterinary Science, 2019
African swine fever (ASF), the most significant threat to the pig industry worldwide, has spread to more than 55 countries on three continents, and it affects more than 77% of the world swine population.

Predator influence on the growth of a population with three genotype II

open access: yesRocky Mountain Journal of Mathematics, 1978
A predator-prey system is proposed in which the prey species consists of three genotypes. It is shown that in the case of no predation, this system satisfies the Hardy-Weinberg principle. In the case where the genotype with the recessive gene has an advantage in its susceptibility to predation, it is shown that the other genotypes move toward ...

Outcome of within-host competition demonstrates that parasite virulence doesn't equal success in a myxozoan model system

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2019
Within-host competition can affect outcomes of infections when parasites occupy the same niche. We investigated within-host competition and infection outcomes in Chinook salmon exposed to two genotypes of Ceratonova shasta (myxozoan parasite).

Genome comparison of African swine fever virus China/2018/AnhuiXCGQ strain and related European p72 Genotype II strains.

open access: yesTransboundary and Emerging Diseases, 2019
African swine fever was introduced into China in August 2018 and led to high mortality in domestic pigs. We reported the genome characterization of the China/2018/AnhuiXCGQ strain mainly based on next-generation sequencing and comparison with related ...

Development of a triplex real-time quantitative PCR for detection and differentiation of genotypes I and II African swine fever virus

open access: yesFrontiers in Veterinary Science, 2023
African swine fever virus (ASFV) was first identified in 1921 and is extensively prevalent around the world nowadays, which has a significant negative impact on the swine industry.

Genotype×environment interactions [PDF]

open access: yesHeredity, 1975
An algebraic formulation, alternative to that of Mather and Jones (1958) and hierarchial rather than factorial in nauture, is presented for describing the differences among the phenotypes produced by a number of genotypes each grown in each of a number of environments.

MHC class II genotype‐by‐pathogen genotype interaction for infection prevalence in a natural rodent‐ Borrelia system

open access: yesEvolution, 2022
MHC genes are extraordinarily polymorphic in most taxa. Host-pathogen coevolution driven by negative frequency-dependent selection (NFDS) is one of the main hypotheses for the maintenance of such immunogenetic variation. Here, we test a critical but rarely tested assumption of this hypothesis-that MHC alleles affect resistance/susceptibility to a ...

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Description of Cryptosporidium ornithophilus n. sp. (Apicomplexa: Cryptosporidiidae) in farmed ostriches

open access: yesParasites & Vectors, 2020
Background Avian cryptosporidiosis is a common parasitic disease that is caused by five species, which are well characterised at the molecular and biological level, and more than 18 genotypes for which we have limited information.
