Lycopodium clavatum as a homeopathic treatment in Magellanic penguins (Sphenicus magellanicus)

Uric acid is the main form of excretion of nitrogenous components in birds. The assessment verification samples, control, check of uric acid concentrations is widely used to detect kidney disease. High concentrations (up to five times) of uric acid in plasma can lead to the precipitation of this acid in the form of crystals, which accumulate in the tissues, mainly in the synovial joints and the viscera surface. Aims: report the evolution of homeopathic treatment in increased uric acid in Magellanic penguins (Spheniscus magellanicus) from Santo André Municipal Zoo. Methodology: 12 animals showed an increase in uric acid (reference values 0,3-16,1mg/dL) and received homeopathic treatment with Lycopodium clavatum 6cH. The protocol established was the administration of two globules of Lycopodium clavatum 6cH, once a day, inside fishes offered in the animal's beak. Treatment started on 25/09/2019. On 30/10/2019 was collected a new blood sample, those who were not discharged were kept on treatment and new collections were made on 27/11/2019 and 17/12/2019. Results: 8 animals had an average uric acid of 20.45mg /dl and responded to the 35-days treatment, normalizing the biochemical values with an average of 12.24mg /dl. Two animals with 18.27 mg /dl were discharged in 62 days with 11.70 mg /dl and another two penguins with 19.85 mg /dl were discharged in 82 days later with 9.57 mg /dl of uric acid. Conclusion: Homeopathy proved to be successful in the treatment of increased uric acid in Magellanic penguins, easy to administer, affordable and without side effects.

Bioavailability of polycyclic aromatic hydrocarbons to penguins on the coast of southeastern Brazil.

Bioavailability of polycyclic aromatic hydrocarbons on São Paulo state coast (southeastern Brazil) was evaluated through the analysis of biliary metabolites in Spheniscus magellanicus (n = 79). The animals analyzed in present study were either found dead during beach monitoring procedures or died at rehabilitation centers. Analyses of naphthalene (NAP), phenanthrene (PHE) and benzo[a]pyrene (BaP) metabolites were performed using a high-performance liquid chromatograph equipped with fluorescence detectors. Total metabolite (TM) concentrations ranged from below the method quantification limit to 270 µg g-1 of bile. TM concentrations were mainly composed of NAP metabolites, followed by PHE metabolites. BaP metabolites were detected in only two samples. This is the first study using PAHs metabolites in S. magellanicus to assess the bioavailability of these compounds in coastal regions.

Atrophic Proventriculitis Associated with Gravid Females of Tetrameres sp. (Nematoda: Tetrameridae) in the Magellanic Penguin (Spheniscus magellanicus) on the Coast of Brazil.

The present study offers the first description of proventriculitis associated with the presence of gravid female nematodes of the genus Tetrameres (Nematoda: Tetrameridae) in 3 juvenile Magellanic penguins (Spheniscus magellanicus) found dead on the coast of Brazil. This study broadens knowledge on parasites associated with these hosts and the real impact of this association.

Persistent organic pollutants in juvenile Magellan penguins (Spheniscus magellanicus) found on the northern shore of the state of São Paulo and southern shore of the state of Rio de Janeiro, Brazil.

In the present study, persistent organic pollutants (POPs) were determined in 25 livers from Magellanic penguins, Spheniscus magellanicus, found on the state of São Paulo and Rio de Janeiro (Brazil). The following concentrations of POPs (wet weight) were found: ∑ PCBs: 18.9-775.8 ng g(-1); ∑ DDTs: 2.3-275 ng g(-1); and ∑ HCHs: 1.0-11.8 ng g(-1). Among the PCBs, there was a predominance of hexachlorobiphenyls (138 and 153) and heptachlorobiphenyls (180 and 187). Among the organochlorines, DDT predominated. Through histopathologic exams a positive correlation was found between HCB and cardiovascular failure (p=0.012), as HCB values (wet weight) were 6.33-96.49 ng g(-1) for positive animals and 2.45-19.63 ng g(-1) for negative animals. Studies on POPs in Magellan penguins contribute to a better understanding of the distribution and trends of these pollutants in the western South Atlantic Ocean.
