RESUMO
The COVID-19 pandemic has resulted in over 3.6 million confirmed cases and over 254,000 deaths worldwide. It has been theorized that children who are asymptomatic or who do not display significant respiratory symptoms are potential vectors for community transmission of the SARS-CoV-2 virus. This is incompletely understood due to the current lack of widespread testing in the pediatric population. We describe a case of a 2-year-old female who presented with symptoms of prolonged fever, conjunctivitis, extremity edema, rash, dry/cracked lips, fussiness and fatigue, and a notable absence of respiratory symptoms. She was diagnosed with and treated for Kawasaki disease. Due to her prolonged fever, she was tested for COVID-19 which was positive; however, she did not develop respiratory symptoms during her illness. At the time of manuscript submission, this is the second case report to our knowledge showing an association between Kawasaki Disease and SARS-CoV-2 virus, both of which are poorly understood diseases in the pediatric population. This case highlights the value of testing pediatric patients for COVID-19 who present with fever in the absence of other symptoms to improve epidemiologic measures during the ongoing pandemic, and it also adds to a foundation of cases for future research on the presence of a link between Kawasaki Disease and COVID-19.
RESUMO
Syngnathid fishes (pipefishes, seahorses, and seadragons) exhibit a wide array of mating systems ranging from monogamy with long-term pair bonds to more promiscuous mating systems, such as polyandry and polygynandry. Some seahorses, including the dwarf seahorse Hippocampus zosterae, have been found to be socially monogamous. Although several seahorse species have also been shown to be genetically monogamous, parentage analysis has not yet been applied to the dwarf seahorse. We developed 8 novel microsatellites for the dwarf seahorse to conduct genetic parentage analysis to confirm that this species is indeed monogamous. Using 4 selected loci and a total of 16 pregnant male seahorses, with 8 collected in Florida and 8 sampled in Texas, we genotyped all of the offspring within each male's brood to determine the maternal contributions to each brood. We found a maximum of 4 alleles per locus segregating within each pregnant male's brood, a pattern consistent with each brood having exactly 1 mother and 1 father. These results support previous laboratory-based behavioral studies and indicate that the dwarf seahorse, H. zosterae, is genetically monogamous.
