| Chlamydophila abortus (C. abortus) infection is related to reproductive failure in domestic ruminants. Although it has not been well characterized worldwide, this pathogen has already been identified in some European countries and in the USA. In Brazil, preliminary studies have shown serological evidence of C. abortus infection in herds with low antibody prevalence. Until now, the identification of C. abortus in biological samples from females presenting reproductive failures has not been described in Brazilian herds of domestic ruminants. The aim of this study was to evaluate the presence of the C. abortus in a collection of abortions from cattle (n=85), sheep (n=12), and goats (n=8), in samples of vaginal mucus from cows (n=13), sheep (n=90), and goats... |

| The common occurrence of multiple papillomavirus infections has been shown in several studies involving the human host. However, investigations with the aim of identifying mixed papillomavirus infections in cattle have been conducted only recently. In the current work we describe a co-infection with two different bovine papillomavirus (BPV) types that was identified in a bovine teat papilloma. The skin wart was obtained from a cow belonging to a Brazilian beef herd. A PCR assay was carried out with the FAP primer pair, which amplifies a partial segment of the L1 gene (approximately 478 bp), and the amplicon was submitted to direct sequencing. Because nucleotide sequences with satisfactory quality scores were not obtained, the amplicon was cloned and... |
