Genomics insights reveal multi-year maintenance of a new #Deltacoronavirus infecting #Seabirds from Cagarras Island Archipelago Natural Monument, #Brazil

Abstract Previous studies have identified various pathogens in seabirds, notably coronaviruses (CoVs) and influenza A viruses (IAVs), due to their potential to cause significant morbidity and mortality . The Cagarras Island Archipelago Natural Monument , located near Rio de Janeiro, Brazil , serves as nesting site for two species, the magnificent frigatebird (Fregata magnificens) and the brown booby (Sula leucogaster). Despite its ecological importance, no prior studies have investigated viral infections in these species, which share habitat interfaces with densely populated human areas . To address this gap, we sampled and tested seabirds for CoVs and IAVs from January 2022 to April 2024. Birds were captured and identified by species, age, and sex. Oropharyngeal and cloacal swabs , as well as blood samples , were collected. Viral RNA was extracted using the QIAamp Viral RNA Mini Kit, and the presence of IAVs was screened via real-time RT-PCR, while CoVs were screened using semi-nested...

Fifth #Update on #Developments in #Iran {#War} (#IAEA, June 22 '25)

  The International Atomic Energy Agency (IAEA) can confirm that the Iranian nuclear sites of Fordow, Natanz and Esfahan have been hit, following U.S. aerial attacks overnight, Director General Rafael Mariano Grossi said today . Based on an analysis of the information available to it , the IAEA assessed that there has been extensive additional damage at the sprawling Esfahan site , which had already been struck several times by Israel since it began targeting Iran’s nuclear facilities on 13 June, Director General Grossi said. The IAEA had previously reported that several buildings at the Esfahan complex were damaged, some of which may have contained nuclear material. “The latest attacks early this morning damaged other buildings in Esfahan . In addition, we have established that entrances to underground tunnels at the site were impacted,” Director General Grossi said. The extent of damage to the Fordow uranium enrichment facility – built deep inside a mountain in central Iran – was...

Fourth #Update on #Developments in #Iran [War] (#IAEA, June 22 '25)

  Director General Rafael Mariano Grossi said he will call an emergency meeting of the IAEA Board of Governors on Monday in light of the “urgent situation” in Iran following the latest attacks on the country’s nuclear facilities . “In view of the increasingly serious situation in terms of nuclear safety and security, the Board of Governors will meet in an extraordinary session tomorrow, which I will address,” Director General Grossi said. The Director General said the IAEA has been informed by the Iranian regulatory authorities that there has been no increase in off-site radiation levels after the recent attacks on three Iranian nuclear facilities, including the Fordow uranium enrichment site. “As of this time, we don’t expect that there will be any health consequences for people or the environment outside the targeted sites,” he said. “We will continue to monitor and assess the situation in Iran and provide further updates as additional information becomes available.” According to...

Third #Update on #Developments in #Iran {War} (June 22 '25)

A large nuclear complex in Esfahan has been targeted for a second time during Israel’s attacks on Iran over the past nine days, with several more buildings struck, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said today . The site in central Iran was first hit on 13 June when four buildings were damaged: the central chemical laboratory , a uranium conversion facility , a reactor fuel manufacturing plant , and an enriched uranium metal processing facility under construction. No increase of off-site radiation levels was reported. Based on information available to the IAEA today, six other buildings at the same site have now also been attacked: a natural and depleted uranium metal production facility which had not yet begun operations, a fuel rod production facility, a building with low-enriched uranium pellet production as well as a laboratory and nuclear material storage , another laboratory building, a workshop handling contaminated equipment ...

Counting Cases, Conserving #Species: Addressing Highly Pathogenic Avian #Influenza in #Wildlife

Abstract Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year-round panzootic with global consequences . Here, we summarize the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife . Over the past five years, HPAI has caused the deaths of millions of wild birds , causing dramatic population declines in several seabird species . However, comprehensive quantitative mortality data remain scarce, as existing records are often anecdotal, focus on localized mass die-offs, and thus represent only a fraction of the true magnitude of mortality. This gap in data limits the ability to predict outbreak dynamics and mitigate long-term consequences. Using the Northwestern European Sandwich Tern (Thalasseus sandvicensis) population as a case study, we demonstrate the value of integrating mortality data with ecological, serological and...

Resurgence of #human #metapneumovirus in the post #COVID19 era: #pathogenesis, epidemiological shifts, clinical #impact, and future #challenges

Summary Human metapneumovirus (hMPV), a respiratory pathogen identified in 2001, is a substantial cause of community-acquired respiratory infections across all age groups. This Review explores the impact of hMPV after the COVID-19 pandemic , emphasising its resurgence as a public health concern . Epidemiological shifts, as well as unusual seasonal patterns , increased co-infection rates, and altered age distributions, have been observed globally. Phylogenetic analysis has shown the variation across three distinct periods , especially before and after the COVID-19 pandemic, in terms of genotypic distribution. Clinical manifestations of hMPV infection range from asymptomatic to severe lower respiratory tract infections , particularly in vulnerable populations. Specific antivirals or vaccines are currently unavailable; consequently, treatment remains supportive. The development of monoclonal antibodies and vaccines leveraging cross-protective strategies against hMPV and related viruses is...

Efficacy of #baloxavir marboxil against #bovine #H5N1 virus in mice

Abstract Since the first detection of highly pathogenic avian influenza (HPAI) H5N1 (clade 2.3.4.4b) in U.S. dairy cattle in early 2024, the virus has spread rapidly, posing a major public health concern as the number of human cases continues to rise. Although human-to-human transmission has not been confirmed, experimental data suggest that the bovine H5N1 virus can transmit via respiratory droplets in ferrets , highlighting its pandemic potential . With no vaccines currently available, antiviral drugs remain the only treatment option. Here, we investigate the efficacy of the polymerase inhibitor baloxavir marboxil (BXM) against this virus in mice. We find that early treatment post-infection is effective, but delayed treatment significantly reduces BXM efficacy and increases the risk of BXM resistance, underscoring the importance of timely BXM administration for effective treatment.

Man in #Cambodia dies of #H5N1 avian #influenza #H5N1

  PHNOM PENH, June 21 (Xinhua) -- A 52-year-old man from southeastern Cambodia's Svay Rieng province had died of H5N1 human avian influenza , becoming the fifth human death from the virus so far this year , the Ministry of Health said in a press statement on Saturday. "A laboratory result from the National Institute of Public Health showed on June 20 that the man was positive for H5N1 virus ," the statement said. Health authorities are looking into the source of the infection and are examining any suspected cases or people who have been in contact with the victim in order to prevent an outbreak in the community, it added. Tamiflu (oseltamivir), an antiviral drug to prevent the bird flu from spreading, was also given out to people who had direct contact with the patient, the statement said. The Southeast Asian country recorded a total of six human cases of H5N1 so far this year, with five deaths. Source: Xinhua,  https://english.news.cn/asiapacific/20250621/e94aafa92dbc446...

Second #Update on #Developments in #Iran {War} (#IAEA, June 21 '25)

  A centrifuge manufacturing workshop has been hit in Esfahan, the third such facility that has been targeted in Israel’s attacks on Iran’s nuclear-related sites over the past week, Director General Rafael Mariano Grossi said today, citing information available to the International Atomic Energy Agency (IAEA). The workshop – which made the machines used to enrich uranium – was previously under IAEA monitoring and verification as part of the Joint  Comprehensive Plan of Action (JCPOA), including with installed Agency cameras. “We know this facility well . There was no nuclear material at this site and therefore the attack on it will have no radiological consequences,” Director General Grossi said. It came a few days after the IAEA on 18 June reported that the Tehran Research Center , where advanced centrifuge rotors were manufactured and tested, had been hit, as had a workshop in the city of Karaj where different centrifuge components were manufactured. There was no radiologica...

#Glial cells promote #infection by #neurotropic #Influenza A viruses in vitro

Abstract Although influenza A viruses (IAV) are notorious respiratory pathogens, some IAV strains can reach and replicate in the central nervous system (CNS) in vivo. In particular, highly pathogenic avian influenza viruses (HPAIV) pose a threat for future pandemics and are linked to greater neurotropic potential . Moreover, neurotropic IAV strains have shown a more significant impact on the onset and pathogenesis of neurodegenerative diseases (NDD). However, despite its clinical relevance , the dynamics and cellular tropism of IAV infection in the CNS are not well understood. In this study, we analyzed the replication of HPAIV H7N7 in vitro using a primary murine triple co-culture system comprising neurons, astrocytes, and microglia . We found that microglia become highly infected early on and induce a strong pro-inflammatory response before undergoing apoptosis . Using fluorescence microscopy with automated single-cell profiling, we found that, in contrast to non-neurotropic H3N2, th...

#IAEA #DG Grossi’s #Statement to #UNSC on #Situation in #Iran (June 20 '25)

  Attacks on nuclear sites in the Islamic Republic of Iran have caused a sharp degradation in nuclear safety and security in Iran. Though they have not so far led to a radiological release affecting the public, there is a danger this could occur . The International Atomic Energy Agency has been monitoring closely the situation at Iran’s nuclear sites since Israel began its attacks a week ago. As part of its mission, the IAEA is the global nerve centre for information on nuclear and radiological safety, and we can respond to any nuclear or radiological emergency. Based on information available to the IAEA , the following is the current situation at Iran’s nuclear sites. Which I offer as a follow up to my most recent report to this Security Council. The Natanz enrichment site contains two facilities . The first is the main Fuel Enrichment Plant . Initial attacks on the 13th of June targeted and destroyed electricity infrastructure at the facility, including an electrical sub-station ...

First #human #infection and management of #Versteria rafei infection restricted to #liver with phylogenetic analysis in the context of known cases

Summary A recently described cestode genus, Versteria, has been implicated in disseminated human disease in North America . We report the first known case of infection with a recently reported species, Versteria rafei , localised to the liver with attempted surgical resection . Through review of other patients known to be infected with this parasite , we established that this is a rare zoonotic infection involving contact with minks and mustelids . Although Versteria belongs to the same family as Echinococcus , there are several important differences. Known Versteria infections in humans typically are symptomatic, quickly involve multiple organs without treatment, and occur in immunosuppressed hosts. Furthermore, albendazole appears to be at least parasitostatic , with a reduction but not a resolution of the lesions under treatment and development of calcifications analogous to changes seen with treatment for alveolar echinococcosis.

Discovery of a Novel #Parahenipavirus, Parahenipavirus_GH, in #Shrews in South #Korea, 2022

Abstract Highly pathogenic henipaviruses (Nipah and Hendra viruses) and parahenipaviruses (Langya virus) have demonstrated significant zoonotic potential . We aimed to identify Henipavirus or Parahenipavirus species in rodents and shrews in South Korea to underline the potential zoonotic transmission risk. Kidney and lung tissues from 285 rodents and shrews were screened for Henipavirus and Parahenipavirus using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) targeting the Gamak virus and Daeryong virus (DARV) sequences. Based on the qRT-PCR results, 75 out of the 285 individuals tested positive , with the highest viral loads in the kidneys of Apodemus agrarius, Crocidura lasiura , and Crocidura shantungensis . A kidney sample from C. shantungensis that exhibited the lowest Ct value was further analyzed using PCR, Sanger sequencing, and metagenomic analysis, yielding a near-complete genome of a novel Parahenipavirus, designated Parahenipavirus_GH (PHNV-...

#Inactivation of #Influenza A Viruses (#H1N1, #H5N1) During #Grana-Type Raw #Milk #Cheesemaking: Implications for Foodborne #Transmission Risk

Abstract Background :  The detection of H5N1 highly pathogenic avian influenza virus (HPAIV) in lactating dairy cattle in the United States , with high viral titers in raw milk, has raised concerns about potential zoonotic transmission through the consumption of unpasteurized milk and raw-milk dairy products. While inactivation studies exist for pasteurized milk, data on virus persistence during the manufacture of raw-milk cheeses remain scarce .  Aim :  To evaluate the survival and inactivation of avian influenza viruses (AIV), including both low pathogenic (LPAIV, H1N1) and highly pathogenic (HPAIV, H5N1) strains, during the production and ripening of Grana-type hard cheeses made from raw bovine milk.  Methods :  Experimental cheesemaking was conducted using raw milk artificially contaminated with A-Duck-Italy-281904-2-06 (H1N1; 10 7,75 EID50 per mL) or A-Duck-Italy-326224-2-22 (H5N1 clade 2.3.4.4b; 10 6,75 EID50 per mL). Cheeses were produced in accordance wi...
