The avian influenza viruses remain an important pathogen to monitor because of their potential impact on human and animal health. Influenza viruses with the hemagglutinin gene (H5 and H7 subtypes) have already been associated with major outbreaks in wild birds and have accounted for the losses of hundreds of millions of domestic poultry. In addition to the impacts of these viruses on birds, there have also been more than 2500 human cases and 1000 deaths. The H5 influenza viruses are disseminated by migratory wild birds and have been associated with 3 waves of global influenza outbreaks. The current third wave started in 2020 and is ongoing. The methods to control this disease has varied between countries, with Europe and North America controlling the virus through culling alone while others (eg, China) are using a ‘‘cull plus vaccination’’ strategy. The strategy adopted by China, the largest poultryproducing country in the world, has resulted in limited losses during the current global outbreak of H5 avian influenza outbreaks, and the near elimination of H7N9. The purpose of this review article was to summarize the damage the recent dissemination of H5 and H7 influenza viruses have caused to poultry and public health, evaluate the origin of the viruses, and discuss the vaccination strategy in China. The authors’ goal is to see vaccination implemented internationally to ensure the dissemination of the virus can be stopped.","PeriodicalId":15102,"journal":{"name":"Journal of Avian Medicine and Surgery","volume":"37 1","pages":"86 - 88"},"PeriodicalIF":0.3,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43077905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five Rhode Island red hens (<i>Gallus gallus domesticus</i>) were administered a single dose of 96 mg/kg SMZ-TMP (80 mg/kg SMZ and 16 mg/kg TMP) IV followed by the same dose orally after a washout period. Following oral dosing, mean SMZ concentrations exceeded the target breakpoint for approximately 12 hours; however, TMP only briefly exceeded the target breakpoint. Bioavailability was 60.5% for SMZ and 82.0% for TMP. Ten naïve birds were allocated into control (n = 4) and treatment (n = 6) groups for a 7-day multi-dose study. Treatment birds received an oral suspension dosed at 16 mg/kg TMP and 80 mg/kg SMZ every 48 hours (on days 1, 3, 5, and 7); TMP tablets were additionally dosed at 25 mg/bird on days 1, 3, 5, and 7, and 50 mg/bird on days 2, 4, and 6.

Diagnostic tests performed on the penguin since the diagnosis and prior to presentation to the veterinary teaching hospital included serial complete blood counts, plasma biochemistry panels, radiographic imaging, blood and plasma heavy metal testing, and infectious disease testing. The abnormal diagnostic test results were consistent with marked regenerative anemia and splenomegaly. At the veterinary teaching hospital, further diagnostic testing was ordered in an attempt to determine the cause of the biliverdinuria and pale oral mucous membranes. The diagnostic tests performed included a full-body contrast computed tomographic scan, upper gastrointestinal endoscopic procedure, bone marrow aspiration and evaluation, saline agglutination testing, blood <i>Plasmodium</i> species polymerase chain reaction screening, a vitamin profile panel, and repeat blood heavy metal testing. The complete blood count demonstrated a marked, regenerative anemia with the presence of dysplastic erythrocytes, and splenomegaly was found on the computed tomographic images without identifying a definitive cause. Primary disease differentials for the diagnosed regenerative anemia included a myelodysplastic syndrome and primary or secondary immune-mediated hemolytic anemia. The penguin was treated with oral prednisolone as an immunomodulatory agent; however, it did not result in a positive treatment response. The patient developed hyporexia, weight loss, and lethargy 2 months post presentation to the veterinary teaching hospital.

General anesthesia with a minimal effect on circulatory dynamics is necessary to perform noninvasive examinations and treatments in animals, including penguins. In this study, alfaxalone (ALFX), an injectable anesthetic agent, was examined to establish the optimal anesthetic method for gentoo penguins (<i>Pygoscelis papua</i>). Alfaxalone was administered intravenously through the metatarsal vein, and anesthesia was maintained by a constant rate infusion (CRI). A biological monitor was used to record numerous clinical indices, and the anesthetic depth was evaluated every 5 minutes during anesthesia; the CRI was adjusted until the optimal anesthetic depth was obtained. Anesthesia depth was assessed, and the CRI rate was adjusted. The CRI was stopped, and the time until recovery was recorded. Blood samples were collected to analyze plasma concentrations of ALFX. The mean total dose of ALFX required for anesthetic induction was 9 ± 1.9 mg/kg, the intubation time was 126 ± 21 seconds, and the maintenance infusion rate of ALFX was 0.3 ± 0.08 mg/kg/min. The time from discontinuation of anesthesia to extubation was 42 ± 23 minutes, and the time to recovery was 90 ± 33 minutes. Significant changes in the heart rate and blood pressure were not observed during the anesthetic events. The plasma concentration of ALFX under stable anesthesia was 6734 ± 4386 ng/mL (range, 3315-14 326 ng/mL).

However, across the continent and into the surrounding islands approximately a dozen other Old World parrots hail from Africa: Coracopsis species, the Vasa parrots; Psittacula species, including the Alexandrine, Echo, and Seychelles parakeets; Agapornis species, the lovebirds; and finally, Poicephalus species, including the commonly seen Meyer’s parrot (Poicephalus meyeri) and, most importantly to this article, the Cape parrot (Poicephalus robustus). Endemic to South Africa, the Cape parrot is listed nationally as critically endangered. The majority of the remaining population can be found in the Eastern Cape and KwaZulu-Natal provinces, with a smaller isolated population in the Limpopo province. It is South Africa’s only extant, endemic parrot species. The Wild Bird Trust’s Cape Parrot Project (CPP) was established in 2009 in South Africa to conserve the Cape parrot with research to fill key knowledge gaps, as well as by partnering with local communities for habitat restoration. It was the first project of the Wild Bird Trust, which was founded by Rutledge ‘‘Steve’’ Boyes, PhD, out of Hogsback, Eastern Cape, South Africa, where Dr Boyes lived while researching Cape parrots in their native habitat. The Trust’s primary objective is keeping birds safe in the wild by securing critical habitat for the benefit of ecosystems, wildlife, and people, in perpetuity. The CPP staff are co–BirdLife South Africa Species Guardians with the Cape Parrot Working Group, and as instrumental stakeholders, their work is closely aligned with the Cape parrot and Mistbelt Habitat Conservation Action Plan developed in 2019. The CPP is funded mainly through private donors and corporate support, both nationally and internationally. Cassie Carstens is the research technician for the CPP in Hogsback. A cultural, trails, and bird guide by trade, Cassie has a BA in Heritage and Cultural Tourism from the University of Pretoria and a BSc in Geography from the University of South Africa. He started in ornithology working as a research assistant for the Fitzpatrick Institute of African Ornithology. A keen photographer, cartographer, and tree climber, he conducts technical fieldwork and research activities across the Cape parrot’s range in South Africa studying their movement patterns, food sources, and breeding behavior. Dr Francis Brooke is the research manager for the CPP in Hogsback. Her research interests lie in the ecology of threatened bird species. She recently completed her PhD in Nature Conservation through Nelson Mandela University, focusing on another threatened species, the Cape vulture (Gyps coprotheres) and, specifically, their vulnerability to renewable wind energy development.
