mermithid nematode infection
Immature form that undergoes metamorphosis before adulthood.
Worker
Occurs during the next molt (every 10–20 days); the mild form resolves in 1–3 days, the severe form leads to disability.
birth time
beauveria bassiana mycosis
From infection to death 7–21 days.
parasitic mites
Heavy rains in summer
Dogs, dolphins, lynx hang out for 9-25 years and party on their birthday three times a year
nocturnal restlessness
loss of appetite
Incubation 14–30 days; death occurs 3–10 days after symptom onset.
