The redness is characterized by onset within 24 hours of the bite. Amoxicillin clavulanate or Penicillin V are the firstline antibiotic agents. 乳腺炎 很多種細(xì)菌的原發(fā)感染都會(huì)引起乳房炎，其它疾病引起的繼發(fā)感染也可能導(dǎo)致乳房炎。 ?瘦弱。 ?咳嗽。 ?皮膚變色，尤其是耳端皮膚（由毒素或心包感染引起）。 ?死亡率升高。 ?體溫升高。 癥狀 母豬與仔豬 ： 少見。這種細(xì)菌本身可導(dǎo)致肺炎，但多數(shù)情況下是作為二次感染繼發(fā)于地方性肺炎（ EP）或繁殖呼吸綜合癥（ PRRS）之后。s foot. African Swine Fever (ASF) ASF is a highly contagious viral disease of domestic pigs manifested by fever, blotching of skin, haemorrhage of the lymph nodes, internal ans and haemorrhage of the gastrointestinal tract.

Lameness Early lesions on coronary band of foot. Old lesions on foot with partial separation of hoof. Old lesions on recovered pig showing banding growing out of hoof. Swine vesicular disease. Snout vesicular lesion. Vesicular lesions on snout. Recently ruptured blister on rim of snout. Recently ruptured blister on foot. Separation of horn following rupture of blister. Ruptured vesicle on snout and tongue. Lesions on coronary band, bulb of heel and supernumerary digit. Recently ruptured vesicle on interdigital space. Ruptured vesicles on coronary band. Separation of bands. Vesicular exanthema of swine (VES) An acute, contagious, viral disease of swine manifested by the formation of vesicles. Vesicular exanthema is indistinguishable from the other swine diseases such as FMD, VS and SVD. Antemortem findings: 1. Incubation: 2–4 days 2. Large number of hogs are affected. 3. Heavy mortality in suckling pigs 4. Blotchy rash in unpigmented skin (exanthema) 5. Vesicles on the snout and in the mouth. Ruptured vesicles result in erosions 6. Loss of weight 7. Walking on their knees (Fig. 122) and lameness 8. Squealing when forced to move Postmortem findings : Vesicles on mucous membranes and skin Vesicular exanthema. Pig walking on knees due to pain from the vesicular lesion on the feet.
