Laboratory Diagnosticians' News Matters

AAVLD President's Message

The year has been very busy thus far for many of our member laboratories due to the ongoing outbreak of highly pathogenic avian influenza (HPAI). The rapid response and efforts to stamp out HPAI have been nothing short of amazing. Veterinary diagnostic laboratories continue to serve a foundational role in protecting human and animal health.

The AAVLD Government Relations Committee and our USAHA partners met in Washington, DC the week of March 20th and had productive meetings with representatives from key agencies including the AVMA, FDA, DHS, ARS, FBI, FSIS, CDC, and APHIS-VS. HPAI was central to many discussions and the current outbreak is very timely as the federal government makes plans for the next farm bill. We continue to advocate for increased funding for the NAHLN with a majority of funding intended for operational support. We are specifically asking that the next farm bill includes an additional 10 million dollars in annual support for the NAHLN.

Discussions with FSIS shed light on current concerns surrounding human salmonellosis cases associated with poultry products and the potential for changes in policy surrounding pre-harvest certification. Serovars of primary concern in current human salmonellosis cases are S. Enteritidis, S. Typhimurium, and S. Infantis.

The CDC explained their collaborative efforts with the Department of Agriculture and the Department of the Interior to establish a National One Health Framework to address zoonotic diseases and advance public health preparedness. More information can be found here:

The CDC is also monitoring salmonellosis from non-poultry sources including bearded dragons, small turtles, backyard flocks, and fish. A dashboard with state-by-state data on Salmonella and other enteric pathogens as well as potential epidemiological links can be found here:

§ http://www.cdc.gov/ncezid/dfwed/BEAM-dashboard.html 

NAHLN leadership explained their findings on reagent stockpiling. The guidance is for all network laboratories to have enough reagents on hand to perform 2 – 4 weeks of testing to prepare for unanticipated reagent shortages. They also estimate that each network laboratory should have capacity to run at least 300-400 samples in an 8-hour shift for the network to sufficiently handle the daily testing requirements in a large-scale outbreak such as ASF or FMD.

Lastly, I would like to remind our membership that the AAVLD/USAHA Annual Meeting will be in Washington, DC in 2023 and that the submission window for abstracts is now open. Please consider submitting an abstract and encourage others in your laboratory to do so as well. The annual meeting is a great place for young researchers and graduate students to present their work before a multi-disciplinary audience and to network with others in their field. I look forward to seeing you at the annual meeting!

AAVLD President

The government meeting was successful in addressing the key issues and challenges facing the country. The meeting participants agreed on a set of concrete actions and commitments to advance the national agenda and promote the well-being of the citizens.

AAVLD Labs in the News

Funds will help NHVDL to expand capacity and reach strategic goals.

Wednesday, February 22, 2023


For more than five decades, the New Hampshire Veterinary Diagnostic Laboratory (NHVDL) at the UNH College of Life Sciences and Agriculture has helped secure animal and public health by providing essential diagnostic services to the Granite State and New England. The NHVDL also provides valuable training to UNH students in the medical laboratory, veterinary and STEM disciplines—experience that these students bring to the workforce and advanced degree programs.

Now, thanks in large part to the support of Sen. Jeanne Shaheen (NH-D), the NHVDL will receive $1.26 million in federal appropriations to expand their diagnostic services and capacity to safeguard the region from emerging infectious disease threats.

JVDI in Focus

Lesions and viral loads in racing pigeons naturally coinfected with pigeon circovirus and columbid alphaherpesvirus 1 in Australia, Nath et al.

Columbid alphaherpesvirus 1 (CoHV1) is associated with oral or upper respiratory tract lesions, encephalitis, and occasional fatal systemic disease in naive or immunosuppressed pigeons. Clinical disease is often reported with CoHV1 and coinfecting viruses, including pigeon circovirus (PiCV), which may cause host immunosuppression and augment lesion development. A natural outbreak of CoHV1 and PiCV coinfection occurred in a flock of 60 racing rock pigeons (Columba livia), in which 4 pigeons succumbed within 7 d of clinical onset. Lesions included suppurative stomatitis, pharyngitis, cloacitis, meningitis, and tympanitis, with eosinophilic intranuclear inclusion bodies consistent with herpesviral infection. In addition, large numbers of botryoid intracytoplasmic inclusion bodies were present in the skin, oral mucosa, and bursa of Fabricius, suggestive of circoviral infection, which was confirmed by immunohistochemistry. The concurrent viral load of CoHV1 and PiCV was high in liver, oropharynx, and bursa of Fabricius. We found PiCV in oro-cloacal swabs from 44 of 46 additional birds of variable clinical status, PiCV alone in 23 birds, and coinfection with CoHV1 in 21 birds. Viral copy numbers were significantly higher (p < 0.0001) for both viruses in clinically affected pigeons than in subclinical qPCR-positive birds. The CoHV1-induced lesions might have been exacerbated by concomitant PiCV infection.

Worth Quoting

If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured or far away.

~Henry David Thoreau

With the coming of spring, I am calm again.

~Gustav Mahler

Behold, my friends, the spring is come; the earth has gladly received the embraces of the sun, and we shall soon see the results of their love!

~Sitting Bull

The beautiful spring came; and when Nature resumes her loveliness, the human soul is apt to revive also.
