“…The VP1 and 2 proteins are formed from differently spliced mRNAs, while VP3 is formed by proteolytic cutting of VP2 (Bergeron et al, 1996). About sixty copies of the capsid proteins are used in the assembly of the virus' icosahedral capsid, as previously reviewed by Streck et al (2015a).…”

“…This, therefore, necessitates the need for a consistent follow-up vaccinations of all breeders appropriately (Jóźwik et al, 2009;Foerster et al, 2016). This limitation, coupled with seeming emergence of new strains of PPV1 that show lower homology with the vaccine strains, therefore necessitates futher development of more efficient vaccines (Jóźwik et al, 2009;Ren et al, 2013;Streck et al, 2015a).…”

A B S T R A C TDetection of infectious viral agents has been on the increase globally with the advent and usage of more sensitive and selective novel molecular techniques in the epidemiological study of viral diseases of economic importance to the swine industry. The observation is not different for the pig-infecting member of the subfamily Parvovirinae in the family Parvoviridae as the application of novel molecular methods like metagenomics has brought about the detection of many other novel members of the group. Surprisingly, the list keeps increasing day by day with some of them possessing zoonotic potentials. In the last one decade, not less than ten novel swine-infecting viruses have been added to the subfamily, and ceaseless efforts have been in top gear to determine the occurrence and prevalence of the old and new swine parvoviruses in herds of pig-producing countries worldwide. The story, however, is on the contrary on the African continent as there is presently a dearth of information on surveillance initiatives of the viruses among swine herds of pig-producing countries in the region. Timely detection and characterization of the viral pathogens is highly imperative for the implementation of effective control and prevention of its spread. This review therefore presents a concise overview on the epidemiology of novel porcine parvoviruses globally and also provides up-to-date highlights on the reported cases of the viral agents in the African sub-region.

“…The present study is the first to report detection of PCV2 and PPV from the Lesser Antilles. PCV2 is considered among the top economically important porcine pathogens, whilst PPV causes economically devastating reproductive disease in breeding sows (Meng, ; Streck, Canal, & Truyen, ; Thacker, ). Therefore, the detection of PCV2 and PPV in St. Kitts is a concern for the regional pork industry.…”

We report here high rates of detection (50.8%, 31/61 pigs) of Torque teno sus virus (TTSuV) in kidneys of slaughter-age, apparently healthy pigs on St. Kitts island, Lesser Antilles. TTSuV1 and TTSuVk2a were detected in 23 (37.7%) and 13 (21.3%) pigs, respectively, including mixed infection in five animals. By nucleotide sequence identities and phylogenetic analysis, significant genetic diversity was observed among both TTSuV1 and TTSuVk2a on St. Kitts, with TTSuVk2a showing higher genetic diversity than TTSuV1. Fourteen (45.2%) and 10 (32.2%) of the TTSuV infected pigs tested positive for porcine circovirus type 2 (PCV2) and porcine parvovirus (PPV), respectively, revealing high rates of co-infection of TTSuV with PCV2 and PPV. This is the first report on detection and genetic diversity of TTSuV from the Lesser Antilles. Also, PCV2 and PPV were detected for the first time in the Lesser Antilles. Considering the impact of pig farming on the regional livestock economy, the increasing demand for local pork and lack of information on emerging and re-emerging porcine viruses in the Lesser Antilles, the present findings have important implications on swine health.

“…The longest recognized parvovirus in pigs is PPV1, which belongs to the genus Protoparvovirus and which is commonly associated with reproductive failures in breeding herds. During the past decade, several novel PPVs have been identified (3), which have been designated PPV2 through PPV6. Unlike PPV1, these new emerging parvoviruses in pigs belong to one of the two new genera, Tetraparvovirus (PPV2 and PPV3) and Copiparvovirus (PPV4, PPV5, and PPV6).…”
