ABSTRACT: Prosthenorchis elegans is an acanthocephalan intestinal parasite reported in neotropical primates. Despite parasitism by P. elegans having already been described in wild marmosets in the Brazilian Atlantic Forest, there are no reports of this infection in wild Geoffroy’s marmoset (Callithrix geofroyi). The aim of this study is to report one case of P. elegans parasitism in a free-ranging C. geoffroyi from Brazilian Atlantic Forest in Espírito Santo state, and characterize the pathological and parasitological findings of this infection. One Geoffroy’s marmoset necropsied at the Vila Velha University’s Veterinary Pathology Laboratory presented intense chronic transmural ulcerative enteritis associated with twenty cylindrical helminths present in the jejunum and ileum. We can conclude that parasitism by P. elegans occurs in free-ranging groups of Geoffroy’s marmosets. Its infection produced severe intestinal lesions even in free-ranging marmoset and therefore is a threat to this animal’s survival in wildlife and can have some impact on primate conservation in the Brazilian Atlantic Forest.

Congenital ocular abnormalities in cervids have been previously reported as individual cases from various regions of the United States and include microphthalmia, anophthalmia, congenital cataracts, dermoids, and colobomata. A common underlying cause for these abnormalities, such as nutritional deficiencies, environmental toxin exposures, or genetic mutations, has not been established. This retrospective study summarized and compared cases of suspected congenital ocular abnormalities in free-ranging white-tailed deer ( Odocoileus virginianus) submitted to the Southeastern Cooperative Wildlife Disease Study (SCWDS) in Athens, Georgia, to the preexisting literature. Of 3645 accessions of white-tailed deer submitted to SCWDS, 15 qualifying case records were found. An additional 15 cases were reported previously in the literature. Conditions described in SCWDS cases included microphthalmia (8/15), congenital cataracts (3/15), anophthalmia (2/15), colobomata (1/15), anterior segment dysgenesis (1/15), ectopic lacrimal gland tissue (1/15), and congenital blindness with corneal opacity (1/15). Most (11/15; 73%) of the SCWDS cases were male fawns with an average age of 4 months at presentation, consistent with previously described cases. Most animals had bilateral abnormalities with few extraocular congenital abnormalities, also consistent with existing reports. Cases were variably tested for various infectious agents at the time of submission; 2 cases were seropositive for bluetongue virus. Spatiotemporal clustering of cases was not evident. This study provided a concise and systematic summary of known existing cases of congenital ocular defects in fawns but did not identify a cause.

SUMMARYThe prevalence ofToxoplasma gondiiin free-ranging chickens (Gallus domesticus) is a good indicator of the prevalence ofT. gondiioocysts in the soil because chickens feed from the ground. The prevalence ofT. gondiiin 76 free-range chickens from Guyana, South America was determined. Antibodies toT. gondiiwere assayed by the modified agglutination test (MAT), and found in 50 (65·8%) of 76 chickens with titres of 1:5 in four, 1:10 in one, 1:20 in five, 1:40 in seven, 1:80 in six, 1:160 in eight, 1:320 in four, 1:640 or higher in 15. Hearts and brains of 26 chickens with titres of <1:5 were pooled in 5 batches and bioassayed in mice. Hearts and brains of 50 chickens with titres of 1:5 or higher were bioassayed in mice.Toxoplasma gondiiwas isolated by bioassay in mice from 35 chickens with MAT titres of 1:20 or higher. All mice inoculated with tissues of 30 infected chickens remained asymptomatic.Toxoplasma gondiiisolates from 35 chickens were genotyped using 11 PCR-RFLP markers including SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, a new SAG2, and Apico. A total of 9 genotypes were identified, with 5 genotypes (nos 1, 4, 5, 6 and 7) unique to Guyana, 2 genotypes (nos 2 and 3) previously identified in chickens from Brazil, 1 genotype (no. 8) previously identified in chickens from Brazil, Costa Rica and Nicaragua, and 1 genotype (no. 9) belonging to the clonal type III lineage that exists globally. Infection with 2 genotypes was found from 1 chicken. This is the first report of genetic characterization ofT. gondiiisolates from any host from Guyana.
