It is manifested either in acute septicaemic form with a high morbidity and death rates or as chronic local forms (independently or secondary to acute ones). Acute fowl cholera. The sudden and unexpected death could be the first sign of the disease. In this form, the lesions are predominantly related to vascular injuries.
70. Commonly observed signs are anorexia, ruffled feathers, oral and nasal mucus discharge, cyanosis and white or greenish watery mucoid diarrhoea. Frequently, subserous petechial or ecchymosed haemorrhages in the anterior part of the small intestine, the gizzard or the abdominal fat are discovered.

E. coli septicaemia in a broiler chicken. H/E, Bar = 40 µm.
73.In layers (commercial or breeders), acute oophorites with regressing follicles and consequently, diffuse peritonites are commonly observed.
74. Chronic fowl cholera. It is characterized by local inflammations. The periorbital sinuses are frequently affected by a serofibrinous inflammation.
75. 76. 77. Another local form is the injury of wattles that are strongly distended because of their filling with fibrinous caseous content. The flocks that recuperated from fowl cholera continue to carry and shed Pasteurella multocida. The carriers store the organism in nasal choanas and contaminate the forage, water and the environment with oral discharges. Wild birds and some mammals (swine) could also carry the agent and introduce it into poultry flocks. Cannibalism is an essential route of spreading the infection.

The diagnosis is made on the basis of disease history, clinical signs, the lesions and the results of bacteriological studies. Fowl cholera should be differentiated from acute E. coli septicaemia, erysipeloid, fowl typhoid etc. The immunization of birds at the age of 8 -12 weeks gives very promising results. Many antibiotics and sulfonamides could lower death rate, but at discontinuation of the treatment, the disease could recur. Sulfonamides are appropriate for treatment, but they inhibit egg-laying.

Hmm it looks like your blog ate my first comment (it was extremely long) so I guess I’ll just sum it up what I submitted and say, I’m thoroughly enjoying your blog. I too am an aspiring blog writer but I’m still new to the whole thing. Do you have any recommendations for inexperienced blog writers? I’d really appreciate it.

I’m not sure exactly why but this site is loading extremely slow for me. Is anyone else having this problem or is it a problem on my end? I’ll check back later and see if the problem still exists.
I am curious to find out what blog platform you have been working with? I’m having some small security issues with my latest site and I would like to find something more safeguarded. Do you have any suggestions?
Pretty nice post. I just stumbled upon your weblog and wished to say that I have truly enjoyed browsing your blog posts. After all I will be subscribing to your feed and I hope you write again soon!

Hey there would you mind letting me know which hosting company you’re using? I’ve loaded your blog in 3 completely different browsers and I must say this blog loads a lot quicker then most. Can you recommend a good hosting provider at a honest price? Cheers, I appreciate it!
Hi there! Someone in my Facebook group shared this website with us so I came to check it out. I’m definitely loving the information. I’m bookmarking and will be tweeting this to my followers! Terrific blog and superb style and design.
Hi there just wanted to give you a brief heads up and let you know a few of the images aren’t loading correctly. I’m not sure why but I think its a linking issue. I’ve tried it in two different internet browsers and both show the same outcome.
Music began playing any time I opened this internet site, so irritating!
