Since the arrival of clade 2.3.4.4b avian influenza A(H5N1) in North America in late 2021, frequent mammal spillover events have occurred in a diverse range of species, including 1 human [...]

Equine influenza is a common, highly contagious respiratory disease of equids with a near-global distribution. Central Asia, Australia, and Japan experienced large equine influenza virus (EIV) outbreaks in 2007 (1,2). [...]

Since the first isolation in 1963 of an avian-origin influenza A(H3N8) virus from horses (1), subtype H3N8 influenza viruses have continued to circulate panzooti cally among horses, causing severe outbreaks [...]

In 2004, 803 rural Iowans from the Agricultural Health Study were enrolled in a 2-year prospective study of zoonotic influenza transmission. Demographic and occupational exposure data from enrollment, 12-month, and [...]

This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of [...]

We evaluated 49 swine industry workers and 79 non-exposed controls for antibodies to swine influenza viruses. Multivariate modeling showed that workers who seldom used gloves (odds ratio [OR] 30.3) or [...]

We conducted a study in the summer of 2004 at county fairs in the Midwest to investigate the role poultry exhibits have in spreading avian pathogens to humans. A nearly [...]

We retrospectively studied 420 pharyngeal swab specimens collected from Peruvian and Argentinean patients with influenzalike illness in 2002 and 2003 for evidence of human metapneumovirus (HMPV). Twelve specimens (2.3%) were [...]

We analyzed 64 human metapneumovirus strains from eight countries. Phylogenetic analysis identified two groups (A and B, amino acid identity 93%-96%) and four subgroups. Although group A strains predominated, accounting [...]

Genetic variation among 166 isolates of human adenovirus 7 (Ad7) obtained from 1966 to 2000 from the United States and Eastern Ontario, Canada, was determined by genome restriction analysis. Most [...]

This article reports on the occurrence of adenovirus type 4-associated acute respiratory disease epidemic at Fort Jackson army base in 1997. Data show that 66.1% of 1,000 hospitalized trainees had an adenovirus infection., In May 1997, a large, persistent epidemic of adenovirus type 4-associated acute respiratory disease began at Fort Jackson, South Carolina, the largest army basic training center. The epidemic lasted until [...]

Cross-species infections with influenza A viruses readily occur between humans and pigs. Pigs often have been infected by human epidemic viruses (1), and swine workers and their family members are [...]

Streptococcus suis is one of the most important pathogens affecting the swine industry. The gram-positive, encapsulated bacterium causes a wide range of clinical disease syndromes in pigs and other domestic [...]

We report serologic evidence of avian influenza infection in 1 duck hunter and 2 wildlife professionals with extensive histories of wild waterfowl and game bird exposure. Two laboratory methods showed [...]

An outbreak of influenza A (H3N2) occurred aboard a U.S. Navy ship in February 1996, despite 95% of the crew's having been appropriately vaccinated. Virus isolated from ill crew members [...]

Emerging respiratory disease agents, increased antibiotic resistance, and the loss of effective vaccines threaten to increase the incidence of respiratory disease in military personnel. We examine six respiratory pathogens (adenoviruses, [...]

We evaluated 76 adenovirus type 7 (Ad7) isolates collected in Iowa from 1992 to 2002 and found that genome type Ad7d2 became increasingly prevalent. By 2002, it had supplanted all [...]

The article discusses a study which examined the transmission of avian influenza A (H7N9) virus among several family clusters in China. Particular focus is given to Chinese guidelines on the prevention of human H7N9 virus infection. Also discussed are serum analysis of antibodies against avian influenza viruses, serologic assay results, and limitation of the study.

Discusses the variety of symptoms which veterans of the Persian Gulf War, 1991 are experiencing from unexplained illnesses. Ascertainment of all active-duty United States (U.S.) military personnel deployed to the Persian Gulf War; Medical conditions of these deployed veterans; Consistency of the study population.

Despite numerous cases of human infection with Streptococcus suis worldwide, human disease is rarely diagnosed in North America. We studied 73 swine-exposed and 67 non-swine-exposed US adults for antibodies to S. suis serotype 2. Serologic data suggest that human infection with S. suis occurs more frequently than currently documented. [ABSTRACT FROM AUTHOR]
