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.
The symptoms are highly fatal to turkeys, but effect less damage in chickens. However, outbreaks in chickens may result in high morbidity, moderate mortality, and extensive culling, leading to overall poor flock performance. [3] Concurrence of Salmonella typhmurium and E. coli was found to cause high mortality in broiler chickens. [6]
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 ]
Chocolate is potentially toxic to chickens, as it is in many other animals. Butter and cheese are too fatty for chickens to eat regularly, as are fried foods like chips.
Infectious coryza is a serious bacterial disease of chickens that affects the respiratory system, and it is manifested by inflammation of the area below the eye, nasal discharge, and sneezing. [ 1 ] [ 2 ] The disease is found all over the world, causing high economic losses, which are due to stumping off and reduction of egg production in case ...
Heterakis gallinarum is a nematode parasite that lives in the cecum of some galliform birds, particularly in ground feeders such as domestic chickens and turkeys. It causes infection that is mildly pathogenic. However, it often carries a protozoan parasite Histomonas meleagridis which causes of histomoniasis (blackhead disease).
Modern breeding of chickens is selective toward "fat thighs and large breast muscles," BBC Wildlife Magazine reports. These traits add extra weight to the bird, making it harder to fly.
The organism should be cultured and antibiotic sensitivity should be determined before treatment is started. Amoxycillin is usually effective in treating streptococcal infections. [1] Biosecurity protocols and good hygiene are important in preventing the disease. [1] Vaccination is available against S. gallolyticus and can also protect pigeons. [1]
