“…With respect to the age of subject animals, the observed RSV seroprevalence of 47% in adult sheep is similar to that reported for Italian sheep in 2000, with 42% [13] and in sheep under a mixed flock system in Peru, with 49.3% [1]. Another study in sheep from Syria reported a higher prevalence, with 63.6% [13].…”

Evidence of respiratory syncytial virus and parainfluenza-3 virus in Mexican sheep

This is a first report in Mexico of the presence of antibodies against respiratory syncytial virus (RSV) and parainfluenza-3 virus in Mexican sheep in different productive stages. We determine the association of serological positivity with age and production system, and obtain molecular evidence of infection by both virus. RSV prevalence in adult sheep was 47% (49/105) at the tropic and 64% (63/99) at the uplands. A significant difference in RSV seropositivity between animals from the tropic and the uplands was observed (P \ 0.05). Seropositivity correlated with production system (P = 0.003, OR = 2.042), with a risk of showing antibodies was 2.042 times higher in sheep under an extensive production system. A significant difference in PI3V seropositivity between animals from either provenance (P = 0.017, OR = 0.475) were also found, with a risk of showing antibodies 0.475 times higher in sheep under an extensive production system. Genetic material from RSV and PI3V was identified by RT-PCR in nasal swab samples from clinically healthy lambs and confirmed by sequencing and phylogenetic analysis. Serological results show that sheep are susceptible to infection by both viruses, and molecular results suggest that the identified antibodies are result of natural infections and reinfections.

“…Little is known about chlamydiosis in wild ruminants, although serologic investigations in Europe suggest a role for wild ruminants as a chlamydial wildlife reservoir (Andreani et al, 1986;Giovannini et al, 1988;Cordier, 1991;Dedek et al, 1991;Cubero-Pablo et al, 2000;Gaffuri et al, 2006). Most studies detected genus-specific antibody response because investigators usually used the complement fixation test (CFT).…”

ABSTRACT:Chlamydiae are obligate, intracellular, gram-negative bacteria that are responsible for important diseases in humans, other mammals, and birds. Studies have shown that chlamydiae could be present in wild ruminants, but the serodiagnostic method most commonly used did not allow identification of chlamydial species. We determined the prevalence of antibodies to Chlamydia pecorum, Chlamydia suis, Chlamydia abortus, and Chlamydia psittaci in 271 red deer (Cervus elaphus) of a central Italian population, by using the microimmunofluorescence test that shows antibody response against genus-specific and species-specific antigens. No sera had detectable antibodies to C. pecorum and C. abortus. Antibodies were detected against C. psittaci (9.6%) and C. suis (3.3%). Antibody response could be related to contact of the red deer with birds and wild boars (Sus scrofa), respectively, and confirm an extended host range of individual Chlamydia species. In view of the potential zoonotic risk related to exposition of C. psittaci, our findings suggest surveillance of wild ruminants as potential reservoirs for chlamydiae.

“…In alpine chamois, high antibody prevalence against BVDV was found in serologic surveys in Italy and Germany (Kleinschmidt, 2004;Gaffuri et al, 2006). Current investigations in Austrian chamois (n599) from the region of Tyrol could not give any evidence to Pestivirus infection in this species (Ignasi, pers.…”

ABSTRACT:During 2007-09, ear-notch samples from free-living (n5527) and farmed (n5237) Austrian red deer (Cervus elaphus elaphus) were tested for bovine viral diarrhea virus type 1 (BVDV-1) and type 2 (BVDV-2) by enzyme-linked immunosorbent assay and single-tube real-time reverse transcription PCR. Ear-notch samples were collected by applying modified ear tags from randomly selected hunter-harvested red deer and from individuals originating from deer holdings. All samples tested negative for BVDV-1 and BVDV-2. Results of this study show no evidence of persistently infected animals. They indicate further that BVDV is playing a minor role in free-living and farmed red deer in Austria. Earnotch samples are an effective tool for in vivo and postmortem detection of BVDV in wildlife. This sample collection technique can be easily used in combination with tagging individual wild animals kept in captivity.
