Fluralaner is a recent external parasiticide, first of a new class of drugs (isoxazoline parasiticides). It is widely used in companion animals both for its wide spectrum (fleas, ticks and other mites) but also for its ease of use (oral tablets given once for 1 to three months). It is known to be eliminated primarily via the feces (>90%) as the unchanged compound.

- - A 16-year-old male Guinea baboon was examined for weakness and wet fur, which had persisted for a week.
- - The diagnosis revealed a pyothorax caused by the bacteria Streptococcus anginosus.
- - Treatment involved surgery and antibiotics, leading to successful recovery as confirmed by imaging and C-reactive protein tests.
Exploratory behaviors describe the actions performed by an animal to obtain information on an object, environment, or individual by using its different senses. Exploration is described in some marine mammals, but not yet in manatees. Our study investigated behavioral and acoustic responses of two groups of Antillean manatees ( = 12 and = 4) housed in zoological parks toward various stimuli involving three sensory modalities: visual, tactile, and auditory.

- - Aspergillosis is a significant health threat for captive penguins, notably caused by airborne spores from Aspergillus molds, leading to treatment challenges and delayed diagnoses.
- - A study in a Paris zoo investigated the exposure risks to Aspergillus for Humboldt penguins, checking both environmental samples and non-invasive clinical samples over several months.
- - Results showed a high presence of Aspergillus strains, mainly A. fumigatus, in the environment, but identified only one azole-resistant strain, suggesting a low prevalence of resistance possibly due to the urban setting of the zoo.
Antimicrobial resistance (AMR) is a critical challenge of the 21st century for public and animal health. The role of host biodiversity and the environment in the evolution and transmission of resistant bacteria between populations and species, and specifically at the wildlife-livestock-human interface, needs to be further investigated. We evaluated the AMR of commensal Escherichia coli in three mammalian herbivore species-impala (Aepyceros melampus), greater kudu (Tragelaphus strepsiceros), and plains zebra (Equus quagga)-targeting populations living under two conditions: captivity (French zoos) and free ranging (natural and private parks in Zimbabwe).
