Definition of Aflatoxicosis in Poultry Aflatoxins are highly toxic, carcinogenic fungal metabolites produced by Aspergillus flavus , A. parasiticus , and others Aflatoxicosis in poultry primarily affects the liver, but immunologic, digestive, and hematopoietic functions may be involved Weight gain, feed intake, feed conversion efficiency, pigmentation, processing yield, egg production, male and female fertility, and hatchability may be affected Some effects are a direct result of intoxication, while others are related indirectly to factors such as reduced feed intake Susceptibility varies, but in general, chickens, ducklings, turkeys, and pheasants are susceptible Signs and Symptoms of Aflatoxicosis in Poultry Unthriftiness to high morbidity and mortality The liver may be acutely reddened due to necrosis and congestion or yellow discolouration due to lipid accumulation; it may have hemorrhages of various sizes and patterns In chronic aflatoxicosis , the liver may be discolored yellow to gray and atrophied. Although the aflatoxins are carcinogenic, tumor formation is rare with the natural disease, probably because the birds do not live long enough for this to occur.

Definition of Swine Dysentery A contagious disease of pig caused by Treponema characterized by mucohemorrhagic diarrhoea affecting the large intestine The transmission occurs through ingestion of contaminated food Signs and Symptoms of Swine Dysentery The acute form of the disease is characterized by severe and often fatal bloody diarrheal. Affected pigs may be wobbly in the hindquarters and show evidence of abdominal pain, such as stretching and kicking at the belly The faeces may be red, resembling tomato ketchup, or may have a black, tarry appearance. Death usually results from dehydration caused by severe diarrheal Pharmacological treatment of Swine Dysentery Lincomycin hydrochloride 10-15 mg/kg, IM, q 12 h for 3 days, or Tylosin 8.8 mg/kg, IM, q 24 h for 3 days Activity: Brainstorming What are the prevention and control measures for Swine Dysentery? Prevention and Control of Swine Dysentery Optimizing sanitation by maintaining pigs on concrete floors that are washed down daily. Adhering to a rodent control program using a professional exterminator Segregating affected pigs in a sick pen, away from healthy pigs, and culling poor-doers Medicating water and/or feed with antimicrobials Stringent sanitation of the premises Vaccination for prevention of swine dysentery may represent a viable alternative; however, the effectiveness of commercially available vaccines appears to be less than optimal Prevention and Control of Swine Dysentery Cont.…. Develop an all-in all-out housing system with disinfection. Slurry channels should be separate Where solid dung passages are used it may be necessary to depopulate the whole house, clean and disinfect and bring in new pigs at weaning time that have not been contaminated Control flies, they can transmit the organism from one group of pigs to another Reduce the movement and handling of pigs to as little as possible particularly at weighing time when transfer of faeces is likely to take place and stress is likely to cause clinical flare ups Do not overcrowd pigs and endeavour to keep a dry environment; the organism will die out quickly on drying. Poor sanitation and wet pens enhance the disease Key Points Swine dysentery (SD), which is caused by a small snake-like bacteria called Brachyspira hyodysenteriae can be one of the most expensive diseases of the growing pig The early symptom is sloppy diarrhoea, which stains the skin of the perineum under the anus, and a rapid hollowing of the flanks In infected herds control is aimed at preventing the movement of the organism between groups of pigs Evaluation What is Swine Dysentery? What are the common signs and symptoms of Swine Dysentery? What is the pharmacological treatment of Swine Dysentery? What are the control measures against Swine Dysentery? References Riviere J.
