Characteristics of Lameness in Sheep: In an article by (Winter, 2008), she states that “lameness is a common cause of welfare and economic concern in most sheep-breeding countries. There are three common lameness problems caused by microbial organisms. These are interdigital dermatitis, foot rot and contagious ovine digital dermatitis (COD). Interdigital dermatitis: is a very common type of lameness in sheep. We can also call him Scald. It is caused by a bacteria known as Fusobacterium necrophorum. (Winter, 2008) explains how the effects of the bacteria are limited to the interdigital skin located between the claws. It has been seen in sheep and lambs of all ages and is particularly common in growing lambs in spring and autumn. F. necrophorum is found abundantly in the environment and in animal feces. It promotes a warm and humid environment. Once affected, the interdigital space appears moist, inflamed and red or gray in color. Footrot: is a secondary microbial infection after the onset of interdigital dermatitis. According to (Winter, 2008) another microbe known as Dicholiobacter nodules. This bacteria coupled with the bacteria F. necrophorum causes the appearance of lesions on the foot. The lesions that occur may reside only in the interdigital space or, in more severe cases, may cause total dethatching of the horn of the foot. According to (Egerton, 2007), the development of footrot depends on the correlation between the host, the environment and the agent. This will help decipher the severity, persistence and onset of the infection. The severity also depends on the strain of D. nodosus that infects the animal. The proteases produced by the bacteria and its fibers will determine the severity of the infection. In a study by (Olse...... middle of paper ...... anointed for the infection, then spreads to the claws, making them painful and swollen. (Winter, 2004) explains how, in a short period of time Over time, pus accumulates and exits the hoof through the coronal band Even after this, the animal is likely to remain severely lame and the affected toes usually remain deformed and swollen. Granuloma: is another. cause of lameness on farms usually associated with over-pairing of the hoof This is not caused by bacteria entering the hoof, but the hoof may have become over-paired due to bacterial infection and a granuloma has it. result. In a study conducted by (Winter, 2008), it locates granulomas on the front of the foot or toe, they are usually made up of vascular growths of granulation tissue This exposed site on the foot can. serve as a reservoir for D. nodus bacteria to reside and continue to infect the herd..
