“…Clinical signs include an abdomen swollen due to peritoneal fluid, fever, weight loss lethargy, anorexia, dyspnoea, ocular abnormalities and neurological signs 8,16,24,25 . Mutations in the spike gene or the accessory genes 3abc and of 7ab of FCoV 8,16,23,26 are thought to result in changes to the virus’s tropism from cells in the enteric tract to macrophages, resulting in the different disease presentation seen with the two biotypes. This change in primary tropism also impacts the virus’s ability to transmit from cat to cat, with the main transmission pathway of FECV being faecal-oral and FIPV typically having relatively poor transmission potential.…”

“…Following two epidemics, SARS-CoV 2002-4 and MERS-CoV 2012-ongoing, and a pandemic of previously unseen proportions, SARS-CoV-2 2019 onwards, coronaviruses no longer need lengthy introductions of importance and scale. They are not only present in the human population, they are also in wildlife 13-15 , companion animals 16-19 and livestock 13,20,21 , and in all species these viruses have major impacts. The innate ability of coronaviruses to recombine with other coronaviruses continues to fuel their species-switching ability.…”

“…Normalmente, os quadros de PIF efusiva, ou úmida, podem apresentar sinais clínicos como inchaço abdominal (onde uma onda fluida pode ser sentida à palpação), sinais oftálmicos (como uveíte) e também podem ser consideradas sintomatologias neurológicas. Já para a PIF não-efusiva, ou seca, em alguns casos, devemos considerar sinais clínicos oftálmicos, que causam lesões oculares, porém, essas não são características, nem patognomônicas (Gao et al, 2023). Outro estudo aponta a presença de lesões neurológicas mais graves, mas também comumente encontradas em gatos com PIF não-efusiva, sendo essas patologias descritas como meningoencefalite e/ou meningomielite (Rissi, 2018).…”

“…Além disso, a PIF não efusiva pode se transformar em efusiva quando o sistema imune está suprimido, ou no estágio final da doença. Presume-se mais a ocorrência da forma "seca", muito provavelmente devido à proteção parcial do sistema imunológico (Gao et al, 2023). Não obstante, independente da forma apresentada, a doença quando manifestada pode proporcionar graves problemas para a saúde do paciente felídeo e sérias preocupações para seu tutor, por sua alta letalidade.…”
