ABSTRACTAvian influenza viruses (AIV) have been classified on the basis of 16 subtypes hemagglutinin (HA) and 9 neuraminidase. Here we describe genomic evidence for a new candidate HA subtype, nominally H19, with large genetic distance to all previously described AIV subtypes, derived from cloacal swab sample Common Pochard (Aythya ferina) in Kazakhstan, 2008. Avian monitoring wild birds especially migratory hotspots such as central Asia is an important approach gain information about...

Abstract In 2015, a mass die-off of ≈200,000 saiga antelopes in central Kazakhstan was caused by hemorrhagic septicemia attributable to the bacterium Pasteurella multocida serotype B. Previous analyses have indicated that environmental triggers associated with weather conditions, specifically air moisture and temperature region antelope calving during 10-day period running up event, were critical proliferation latent bacteria comparable conditions accompanying historically similar die-offs...

Paretic and paralyzing syndromes affecting wild birds are widely described in the literature, with outbreaks showing an increase frequency intensity worldwide during recent years. In Iberian Peninsula, a paretic clinical picture without known etiology mostly gulls has been reported last few decades. This syndrome (PS) affects waterbirds is characterized by set of signs ascendent flaccid paralysis, dyspnea, diarrhea at different levels severity. study presents first macro-analysis some...

The Caspian seal (Pusa caspica) has declined by more than 90% since 1900 and is listed as endangered IUCN. We made the first quantitative assessment of by-catch mortality in fisheries north Sea conducting semi-structured interviews fishing communities along coasts Russia (Kalmykia, Dagestan), Kazakhstan Turkmenistan. recorded a documented minimum 1,215 seals survey sample, for 2008–2009 season, 93% which occurred illegal sturgeon fisheries. Due to nature fishery, accurately quantifying total...

Bats (Chiroptera) are important natural reservoirs of various viruses, characterized by a broad host range and evolutionary flexibility. In this study, novel herpesvirus (Bat KZ, Alphaherpesvirinae, genus Simplexvirus) was identified in bats inhabiting the southern regions Kazakhstan using high-throughput sequencing PCR methods. The obtained data deepen our understanding bats' viral diversity country highlight their significant role circulation emerging viruses with potential epidemiological...

ABSTRACT A novel avian paramyxovirus was identified during annual viral surveillance of wild bird populations in Kazakhstan 2013. The virus isolated from a white fronted goose ( Anser albifrons ) northern Kazakhstan. Here, we report the complete genome sequence isolate, which suggest should constitute serotype.

Screening wild birds for avian paramyxoviruses is of increasing importance. 6913 samples tracheal and cloacal swabs were collected during 2002–2013 tested to study the prevalence APMVs in avifauna Kazakhstan. As a result, 45 isolates obtained this period their ecological niches genetic relationships defined. Tracheal from using sterile placed viral transport medium kept liquid nitrogen until delivery laboratory. Samples inoculated into 10-day-old embryonated chicken eggs reverse...

Influenza A viruses are important pathogens that can cause diseases with high mortality in humans, animals, and birds; wild birds considered the primary reservoir of all subtypes nature. After discovering H9 influenza bats, questions arose about their potential to serve as an additional natural priority viral origin: Did virus initially circulate bats then transmit or vice versa? subtype particular interest because fatal infections humans caused by H5, H7, H10 contained RNA segments from...

In the winter of 2023/2024, mass death swans was observed on Lake Karakol eastern coast Caspian Sea. From 21 December 2023 to 25 January 2024, 1132 swan corpses (Cygnus olor, Cygnus cygnus) were collected and disposed by veterinary services ecologists. Biological samples from 18 birds for analysis at different dates epizootic. It found that influenza outbreak associated with a high concentration migrating as result sharp cold snap in northern regions. At epizootic, three avian A/H5N1 viruses...

Disease surveillance of marine mammal populations is essential to understand the causes strandings, identify potential threats animal health, and support development conservation strategies. Here we report first large multi-pathogen screening prevalence for viruses, bacteria parasites in a sample 177 live, healthy, wild Caspian seals ( Pusa caspica ), captured released during satellite telemetry studies 2007-2017. Employing molecular serological assays assess pathogens known be significance...

The influenza virus strain A/chicken/North Kazakhstan/184/2020 (H5N8) was isolated in North Kazakhstan during a highly pathogenic avian outbreak 2020. This study aimed to obtain the complete genome sequence of isolate.

Three isolates APMV/gull/Kazakhstan/5976/2014, APMV/gull/Kazakhstan/ 5977/2014 and APMV/gull/Kazakhstan/5979/2014, were obtained from independent samples during annual surveillance for avian influenza paramyxoviruses in wild birds the Caspian Sea coast Western Kazakhstan, initially identified as putative on basis of electron microscopy. Hemagglutination Inhibition Assays with antisera to nine known APMV serotypes (APMV1-9) indicated no relation any them. Next generation sequencing whole...

Aislamiento y caracterización genética de un nuevo adenovirus asociado con la mortalidad masiva en cormoranes grandes (Phalacrocorax carbo). En 2021 se registró una alta carbo) el lago Alakol, este Kazajstán, cuando murieron alrededor del 20% las aves jóvenes. La secuenciación alto rendimiento reveló presencia supuesto cormorán significativamente divergente los aviadenovirus conocidos. Sugerimos que puede considerarse amenaza emergente para salud conservación esta especie.

The review presents information on epizootic diseases in marine mammals caused by influenzaviruses of genera A and B, morbilliviruses, adeno-, herpes-, calici- coronoviruses. Virological serologicaldata about the spectrum viral infections are given. Describes events mammalsinduced influenza viruses isolation strains with antigenic formulas H1N1, H1N3, H3N3, H3N8,H4N5, H4N6, H7N7, H10N7, H13N2, H13N9. It is suggested that seals may be infected a wide range ofinfluenza direct transmission...

High mortality in Caspian Terns (Hydroprogne caspia) and Great Black-headed Gulls (Larus ichthyaetus), was recorded on the northeastern shores of Sea June 2013. Retrospective high throughput sequencing archived tissue samples conducted 2018 revealed presence recently identified novel gull adenovirus similar to that associated with gulls Netherlands 2001. We suggest this specifically can be considered as an emerging threat health conservation terns.

Five avian paramyxoviruses of serotype 8 (APMV-8) were isolated during a study monitoring wild birds in Kazakhstan 2013 and each was further characterized. The viruses from three White-fronted geese (Anser albifrons), one Whooper swan (Cygnus cygnus), Little stint (Calidris minuta). Before our study, only two complete APMV-8 sequences had been reported worldwide since their discovery the USA Japan 1970s. We report genome newly detected analyze genetic evolution over four decades.

In 2015, in the Kazakh part of northern Caspian Sea region, during monitoring wild birds for avian influenza viruses, a highly pathogenic A/flamingo/Mangistau/6570/2015(H5N1) virus was isolated from dead flamingo. This study aimed to obtain complete genome sequence isolate.

A retrospective phylogenetic characterization of the hemagglutinin, neuraminidase and nucleoprotein genes equine influenza virus A/equine/Kirgizia/26/1974 (H7N7) which caused an outbreak in Kirgizia (a former Soviet Union republic, now Kyrgyzstan) 1977 was conducted. It defined that it closely related to strain London/1973 isolated Europe shared a maximum nucleotide sequence identity at 99% with it. This Central Asian isolate did not have any specific genetic signatures can be considered as...

Artemia (brine shrimp) holds significant value as a live feed for larval fish and crustaceans, owing to their distinctive dietary requirements. However, it is vital acknowledge that also carries potential risk vector of infection. We conducted metagenomic analysis explore the virome present in cysts collected from inland salt lakes across four distinct regions Kazakhstan. This study identified presence dsDNA phages RNA virus sequences, with predominant representation Reoviridae, Nodaviridae,...
