A healthy young man developed acute gastroenteritis after handling an infected bao constrictor. The animal died after contracting "mouth-rot disease", a progressive ulcerative stomatitis of snakes charactistically caused a Aeromonas species. Stool cultures from the patient yielded a heavy growth of Aeromonas (Plesiomonas) shigelloides but no other enteric pathogens. Treatment wit sulfamethoxazole-trimethoprim resulted in rapid relief of clinical symptoms. Aeromonas species are not considered part of the normal human fecal flora and gastroenteritis due to this organism is rare. Furthermore, this case appears to represent a new zoonosis: human Aeromonas (Plasiomonas) gastroenteritis derived from contact with an infected animal host.

Man's susceptibility to the virus of foot- and-mouth disease (FMD) was debated for many years. Today the virus has been isolated and typed (type O, followed by type C and rarely A) in more than 40 human cases. So no doubt remains that FMD is a zoonosis. Considering the high incidence of the disease (in animals) in the past and in some areas up to date, occurrence in man is quite rare. In the past when FMD was endemic in Central Europe many cases of diseases in man showing vesicles in the mouth or on the hands and feet were called FMD. The first suggestion of a human infection with FMD was reported in 1695 by Valentini in Germany [7]. All reports before 1897, the year of the discovery of the virus of FMD by Loeffler and Frosch [2], were not of course confirmed either by isolation of the virus or by identification of immunoglobulins after infection. Nevertheless the successful self-infection reported by Hertwig in 1834 most likely seems to have been FMD in man: each of three veterinarians drank 250 ml of milk from infected cows on four consecutive days. The three men developed clinical manifestations. The diseases most often confused with FMD are infections with several viruses of the Coxsackie A group (this infection is referred to as "hand and mouth disease"), herpes simplex and sometimes vesicular stomatitis. Beginning in 1921 up to 1969 at least 38 papers were published, which described clinically manifest FMD in man in more than 40 proven cases. One further reported described an asymptomatic infection with FMD in man [10]. Criteria for establishing a diagnosis of FMD in man are the isolation of the virus from the patient and/or identification of specific antibodies after infection. Laboratory tests for diagnosis of human FMD are the same as for animals. Proven cases of FMD in man have occurred in several countries in Europe, Africa and South America. The type of virus most frequently isolated man is type O followed by type C and rarely A. The incubation period in man, although somewhat variable, has not been found to be less than two days and rarely more than six days.

Complement activation mediated by the major xenogeneic epitope in the pig, galactosyl-alpha(1-3) galactosyl sugar structure (alpha-Gal), and human natural antibodies could cause hyperacute rejection (HAR) in pig-to-human xenotransplantation. The same reaction on viruses bearing alpha-Gal may serve as a barrier to zoonotic infection. Expressing human complement regulatory proteins or knocking out alpha-Gal epitopes in pig in order to overcome HAR may therefore pose an increased risk in xenotransplantation with regard to zoonosis. We investigated whether amphotropic murine leukemia virus, porcine endogenous retrovirus, and vesicular stomatitis virus (VSV) budding from primary transgenic pig aortic endothelial (TgPAE) cells expressing human CD55 (hCD55 or hDAF) was protected from human-complement-mediated inactivation. VSV propagated through the ST-IOWA pig cell line, in which alpha-galactosyl-transferase genes were disrupted (Gal null), was also tested for sensitivity to human complement. The TgPAE cells were positive for hCD55, and all pig cells except the Gal-null ST-IOWA expressed alpha-Gal epitopes. Through antibody binding, we were able to demonstrate the incorporation of hCD55 onto VSV particles. Viruses harvested from TgPAE cells were relatively resistant to complement-mediated inactivation by the three sources of human sera tested. Additionally, VSV from Gal-null pig cells was resistant to human complement inactivation. Such protection of enveloped viruses may increase the risk of zoonosis from pigs genetically modified for pig-to-human xenotransplantation.

Orf virus, pseudocowpox virus and bovine papular stomatitis virus, are parapoxviruses, associated with domestic ruminants, which are capable of causing cutaneous infections in humans. Owing to virtually identical appearances in humans, clinical differentiation of these viruses is difficult. We discuss three recent occurrences of parapoxvirus infection, involving contact with domestic bovine and use a combination of molecular and epidemiological data in the diagnosis. These cases underscore the utility of modern diagnostic tools, along with species-specific contact information in acquiring a definitive diagnosis, in the case of suspected parapoxvirus infection.

Ecthyma contagiosum (orf) is caused by a parapox virus, which results in ulcerative stomatitis of mainly sheep and goats. The disease may be transmitted to humans through direct contact. Complications are rare in healthy individuals, who rarely report the disease. Two married, recreational sheep farmers, were bitten on their index fingers by an affected lamb. While the husband made an uneventful recovery after oral flucloxacillin, his wife was admitted to hospital with necrosis of her finger, cellulitis and lymphangitis requiring intravenous clindamycin. She subsequently developed a generalized maculo-papular rash, which was initially thought to be an adverse drug reaction, but, on hindsight, may have been erythema multiforme associated with orf. Orf is a common zoonosis, rarely reported in general practice. The disease is usually self-limiting and resolves in 6-8 weeks, but complications may occur. The diagnosis should be considered in at-risk occupational and religious groups.

In 2008, two deer hunters in Virginia and Connecticut were infected with a unique strain of pseudocowpox virus, a parapoxvirus. To estimate the prevalence of this virus, and in an attempt to define the reservoir, Parapoxvirus surveillance was undertaken between November 2009 and January 2010. 125 samples from four ruminant species (cows, goat, sheep and white-tailed deer) were collected in Virginia, and nine samples from white-tailed deer were collected in Connecticut. We found no evidence that the parapoxvirus species that infected the deer hunters is circulating among domesticated ruminants or white-tailed deer. However, parapoxvirus DNA of a different parapoxvirus species, bovine papular stomatitis virus (BPSV), was detected in 31 samples obtained from asymptomatic cattle in Virginia. Parapoxvirus DNA-positive cattle originated from the same counties indicating probable transmission among animals. Molecular analysis identified BPSV as the parapoxvirus affecting animals. Asymptomatic parapoxvirus infections in livestock, particularly young animals, may be common, and further investigation will inform our knowledge of virus transmission.
