“…Pestiviruses can be the cause of miscarriages or the birth of shaker kids in domestic goats and might cause the same in wild ibexes. The sperm variables were not affected in the seropositive animals, unlike reports documenting poor semen quality in infected bulls (Revell et al 1988;Paton et al 1989).…”

Potential impact of diseases transmissible by sperm on the establishment of Iberian ibex (Capra pyrenaica) genome resource banks

The long-term cryopreservation of the germplasm (spermatozoa and oocytes) of threatened species offers flexibility in their genetic management and security against disasters or outbreaks of disease that might seriously affect subpopulations. A wide range of infectious diseases can, however, be transmitted via artificial insemination, and the risk of infectious diseases being spread via manipulated germplasm needs to be carefully managed in order to avoid fertility problems in the dams and decreased survival of offspring. Furthermore, accidental introduction of exotic microorganisms into ecosystems remain a major threat. The aims of the present study were to assess the impact of diseases transmissible by sperm on the establishment of germplasm banks for the Iberian ibex, a wild mountain ungulate, and to determine the influence of the presence of these pathogens on sperm functionality. Blood and sperm samples were obtained from 52 mature ibex males legally shot in southern Spain. Sperm motility, morphological abnormalities, acrosome integrity and plasma membrane integrity were assessed for each sample to determine in vitro sperm quality. All serum samples underwent serological analysis for bovine herpes virus type I, bluetongue virus (BTV), bovine leukaemia virus, caprine arthritis-encephalitis virus, pestivirus, Brucella, Coxiella burnetii, Chlamydiophila abortus, Mycoplasma agalactiae and Borrelia burgdorferi. The highest prevalence (30.7%) was recorded for B. burgdorferi, followed by C. burnetii (13.4%). A total of 734 sperm doses containing approximately 200× 10 6 spermatozoa each were frozen in straws. Forty-five straws (6.1% of the total number) came from animals seropositive for diseases listed in the Terrestrial Animal Code of the OIE for collection and processing of bovine and small ruminant semen (in this case, pestivirus and BTV). A total of 271 frozen straws (36.9% of the total of frozen straws) were provided by animals seropositive for pathogens potentially transmissible by semen not included in the above OIE code (in this case, B. burgdorferi and C. burnetii). The values of sperm variables were not affected by seropositivity for any of the pathogens transmissible by sperm.

“…Also acutely infected cattle shed virus in excretions and secretions during viremia (Houe, 1995). BVDV is also excreted in semen in both acutely and persistently infected bulls (Whitmore et al, 1978;Meyling and Jensen, 1988;Paton et al, 1989;Kirkland et al, 1991Kirkland et al, , 1994Kommisrud et al, 1996).

“…An acute infection may result in fever, diarrhoea, reduced milk yield, weight loss, anorexia, depression and coughing (Peterson 2010). Bulls may suffer a reduction in sperm motility and an increase in sperm abnormalities (Paton et al 1989). Subclinical infections are often undetected by the herd owner.…”

“…BVDV can induce a broad range of disease in cattle including; fever, diarrhoea, ill thrift, reduced milk yield, reduced reproductive performance, immunosuppression and, in a high proportion of cases, subclinical infection which often may go undetected (Peterson 2010;Paton et al 1989;Grooms 2004;Lanyon et al 2004;…”

The genotype and subgenotype was established for 325 field viruses and one commercial vaccine viral strain based on the analysis of at least one genomic region. BVDV-1a was the prominent subgenotype (n=317) with BVDV-1b (n=6), BVDV-1d (n=1) and BVDV-1e (n=1) also observed. A number of nucleotide sequence alignments and phylogenetic trees were constructed to represent the relationship between Irish field viruses and reference strains representative of all known BVDV genotypes and subgenotypes. Evidence of both herd specific clustering and circulation of multiple strains within herds was observed; however no evidence of county specific clustering was observed. A number of completely conserved nucleotide regions were observed and the 5'UTR was found to be more conserved than the N pro fragment analysed. The results of this study provide a detailed and comprehensive insight into the genetic diversity of BVDV in circulation within Irish cattle herds and will act as a baseline reference for future BVDV genotyping studies.
