Ergotism, which occurs when poultry feed is contaminated with toxic alkaloids produced by fungi of the genus Claviceps [11] Aspergillosis, a non-contagious disease caused when birds inhale Aspergillus spores that cause breathing to be hard for the bird [12] Ringworm
Virulent Newcastle disease (VND), formerly exotic Newcastle disease, [1] is a contagious viral avian disease affecting many domestic and wild bird species; it is transmissible to humans. [2] Though it can infect humans, most cases are non-symptomatic; rarely it can cause a mild fever and influenza-like symptoms and/or conjunctivitis in humans.
Avian infectious bronchitis (IB) is an acute and highly contagious respiratory disease of chickens.The disease is caused by avian infectious bronchitis virus (IBV), a coronavirus (Coronaviridae, Orthocoronavirinae, genus Gammacoronavirus, subgenus Igacovirus), [1] and characterized by respiratory signs including gasping, coughing, sneezing, tracheal rales, and nasal discharge.
It causes chronic respiratory disease (CRD) in chickens and infectious sinusitis in turkeys, chickens, game birds, pigeons, and passerine birds of all ages. [1] [2] Mycoplasma gallisepticum is a significant pathogen in poultry. Mycoplasmosis is the disease caused by infection with mycoplasmas. Mycoplasmas have many defining characteristics.
Since then, the number of outbreaks in poultry, as well as the number of human cases, dropped significantly. In humans, symptoms and mortality for both LPAI and HPAI strains have been similar. [80] Although no human H7N9 infections have been reported since February 2019, the virus is still circulating in poultry, particularly in laying hens.
Signs of gastrointestinal disease (Haemorrhagic Enteritis) include diarrhea, anorexia, melena and hematochezia. Anaemia and dehydration may develop secondary to this haemorrhagic enteritis. Signs of reproductive disease (Egg Drop Syndrome) include low egg production/hatching and the laying of abnormal eggs (size, shape, colour, texture).
Dermanyssus gallinae (also known as the red mite) is a haematophagous ectoparasite of poultry.It has been implicated as a vector of several major pathogenic diseases. [1] [2] Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans, where the condition it causes is called gamasoidosis.
Chlamydia psittaci is a lethal intracellular bacterial species that may cause endemic avian chlamydiosis, epizootic outbreaks in other mammals, and respiratory psittacosis in humans. Potential hosts include feral birds and domesticated poultry, as well as cattle, pigs, sheep, and horses.
