SEROLOGIC SURVEY FOR SELECTED VIRAL AND BACTERIAL SWINE PATHOGENS IN COLOMBIAN COLLARED PECCARIES (PECARI TAJACU) AND FERAL PIGS (SUS SCROFA)

Abstract

In South America, wild populations of peccaries coexist with domestic and feral pigs, with poorly understood consequences. We captured 58 collared peccaries ( Pecari tajacu) and 15 feral pigs ( Sus scrofa) in locations of Colombia where coexistence of these species is known. Blood samples were tested for antibodies against four viral agents, classical swine fever virus (CSFV), Aujeszky's disease virus (ADV), porcine circovirus (PCV-2), and vesicular stomatitis virus (New Jersey and Indiana subtypes) and two bacterial agents, Brucella spp. and six serovars of Leptospira interrogans. The prevalence of CSFV was 5% (3/58) in collared peccaries and 7% (1/15) in feral pigs. The prevalence of PCV-2 was 7% (1/15) in collared peccaries and 67% (2/3) in feral pigs. Vesicular stomatitis prevalence was 33% (8/24) in collared peccaries and 67% (4/6) in feral pigs. Leptospira prevalence was 78% (39/50) in collared peccary and 100% (8/8) in feral pigs; bratislava, grippotyphosa, icterohaemorrhagiae, and pomona were the most frequent serovars. Also, the only white-lipped peccary ( Tayassu pecari) sampled was positive for L. interrogans serovar bratislava and for vesicular stomatitis virus, New Jersey strain. No samples were positive for ADV or Brucella. The seroprevalence of antibodies against L. interrogans was similar to that observed in other studies. Icterohaemorrhagiae appears to be a common serovar among in situ and ex situ peccary populations. Positive antibodies against PVC-2 represent a novel report of exposure to this pathogen in Colombian peccaries. Our results indicate the possible transmission of various pathogens, important for pig farms, in the studied pig and peccaries.

Epidemiological survey of leptospirosis in collared peccaries (Pecari tajacu Linnaeus, 1758) in legal breeding sites in some states in the Northeast region, Brazil

“…In Mexico, two collared peccaries were positive for the Icterohaemorrhagie and Panama serogroups ((Luna-Alvarez, Moles-Cervantes, Torres- Barranca & Gual-Sill, 1996). In Colombia it was reported that 39 (78 %) free-living collared peccaries showed a high prevalence for serogroups Australis, Icterohaemorrhagiae, Grippotyphosa, Canicola, and Pomona (Montenegro et al, 2018). Thus, it is possible to indicate the participation of these animals as links in the epidemiological chain of the disease and, probably, the lower prevalence in this study may be associated with the better sanitary control offered to captive animals (8.33 %), differently from free-living ones.…”

Captive collared peccary carries ESBL-producing diarrheagenic Escherichia coli pathotypes

“…The prevalence of Leptospira spp. (78%) in collared peccaries was recently reported, the most frequent serovars are bratislava, grippotyphosa, icterohaemorrhagiae and pomona (Montenegro et al, 2018). Collared peccaries have also been found to harbour classical swine fever virus (5%), porcine circovirus type 2 (7%) and vesicular stomatitis (33%).…”

“…Collared peccaries have also been found to harbour classical swine fever virus (5%), porcine circovirus type 2 (7%) and vesicular stomatitis (33%). They also share pathogens with domestic and wild pigs (Sus scrofa) (Montenegro et al, 2018;Molina-Barrios et al, 2018).…”

Hepatitis E Virus (HEV) infection in captive white‐collared peccaries ( Pecari tajacu ) from Uruguay

“…Surveillance of pathogens in wild animals is crucial to understand the epidemiology of infectious diseases which can impact in both human and livestock health. Notably, peccaries and swine (domestic pigs and wild boars) share susceptibility to several important infectious agents as Classical Swine Fever virus and Leptospira (de Castro et al., 2014; Corn, Lee, Erickson, & Murphy, 1987; Montenegro et al., 2018). HEV, which is widely distributed in swine populations worldwide, has never been reported to infect peccaries.…”
