ABSTRACT Isolates of the toxic, N2-fixing species Cylindrospermopsis raciborskii from various geographic locations were analyzed with respect to their genetic diversity based on the nifH and cpcBA-IGS genes. Gene sequences clustered according to their geographic origin, with the nifH sequences separating into European, Australian, and American groups and the cpcBA-IGS sequences separating into American and European or Australian groups. PCR primers for both genes were designed to exclusively amplify DNA from Cylindrospermopsis species, and an additional primer set for cpcBA-IGS was designed to specifically amplify the American C. raciborskii strains.

Porcine circovirus type 2 (PCV-2) has been associated with syndromes grouped by the term porcine circovirus associated diseases (PCVAD). The PCV-2 isolates have been grouped into two major groups or genotypes according to their nucleotide sequence of whole genomes and/or ORF-2: PCV-2b, which have, in turn, been subdivided into three clusters (1A–1C), and PCV-2a, which has been subdivided into five clusters (2A–2E). In the present study, we obtained 16 sequences of PCV-2 from different farms from 2003 to 2008, from animals with confirmatory diagnosis of PCVAD. Since results showed an identity of 99.8% among them, they were grouped within a common cluster 1A-B. This preliminary study suggests a stable circulation of PCV-2b among the Argentinean pig population.
