RESUMO

OBJECTIVE: To determine pulmonary anthracosis in zoo, wildlife, and companion animals of Jeollabuk-do Province, South Korea. ANIMALS: A total of 350 animals of 61 different species, belonging to 3 classes (mammals: n = 38; avian: 21; and reptiles: 2) from different habitats in Jeollabuk-do Province, were examined. PROCEDURES: Gross lung examination and tissue sampling were done at postmortem, and histopathological analysis was microscopically done on hematoxylin and eosin-stained slides. RESULTS: Macroscopic analysis of anthracotic lung tissue revealed minute (pinpoint size) spots and black pigmentation in a scattered and/or coalescing fashion. The presence of carbon particles was noted in 154 (44%, 154/350) cases. Based on habitation, zoo animals had the highest frequency of anthracosis in the lung (55.2%, 69/125), followed by companion animals (45.2%, 56/124) and wildlife animals (28.7%, 29/101). There was an association between habitation and the presence of anthracosis (P < .05). CLINICAL RELEVANCE: This study revealed evidence that the presence of anthracosis is associated with the environmental air quality of zoo, wildlife, and companion animals in Jeollabuk-do Province, South Korea. Air pollution may affect the respiratory health of the endangered species at the Jeonju Zoo as well as the human population. Continuous monitoring of particulate matter and establishing policies that control industrialization around the province would enable quick action to curb any potential respiratory health risks to animals kept in the urban cities of the province.

RESUMO

Improved methods for efficient excystation of Eimeria should be developed and standardized for future Eimeria-related studies. Here, the effects of different glass bead sizes (0.5, 1, 2, and 2.5 mm), and various vortex speeds (1000, 2000, and 3000 rpm) and durations (30 s, 1, 3, and 5 min) have been examined for Eimeria (E.) acervulina oocyst excystation. At 3000 rpm, all glass beads, regardless of size, efficiently ruptured E. acervulina oocysts at 5 min. At 2000 and 3000 rpm, all four glass bead sizes increasingly ruptured oocysts in a time-dependent manner. In contrast, at 1000 rpm the excystation efficiency was not related with the glass bead size or with vortexing duration. It appeared that the 1mm glass beads are most efficient for E. acervulina DNA extraction at a 3000 rpm vortexing speed for 3 and 5 min. The 2 mm glass beads delicately released the highest number of intact sporocysts at 2000 rpm for 3 min. Therefore, our data can provide valuable information for the efficient mechanical excystation of E. acervulina.
