Porcine circovirus–associated diseases (PCVADs), caused by porcine circovirus 2 (PCV-2), have a significant economic impact on the swine industry worldwide. In Africa, there is little information, to date, regarding the occurrence of PCV-2, and it has not been reported in Mozambique’s swine population. We randomly collected mesenteric lymph nodes ( n = 111) from slaughtered pigs from 9 districts in southern Mozambique. PCV-2 DNA was detected in 54% (62 of 111) of the samples and 78% (23 of 31) of the farms. PCV-2 antigen was detected by immunohistochemistry in lymph nodes (6 of 62; 10%) that were positive for PCV-2 by PCR. Histopathologic changes observed in these lymph nodes were lymphoid depletion, multifocal nodal necrosis, and infiltrates of histiocytes and multinucleate giant cells. One positive sample from each district was selected in order to obtain sequences covering the ORF2 region. Five sequences clustered with PCV-2d, of which 3 sequences from Maputo, Namaacha, and Moamba were grouped with PCV-2d-2; 2 sequences from Manhiça and Matola were grouped as PCV-2d-1; and 4 sequences from Boane, Matutuíne, Chibuto, and Xai-Xai were closely related to PCV-2b-1A/B genotypes. Our study indicates that a diversity of PCV-2 viruses is circulating in the Mozambican swine population.
