Sheep Facial Eczema Prevent

Sheep Facial Eczema Prevent

A Clinical Research Laboratory of endemic foci Eczematous damp syndrome in cattle in Jhapa district of Nepal

Background:

The breeding of Jhapa district reported the incidence of the syndrome similar to what has been described as disease Degnala. In total, 56 animals were affected of which 12 of them died during treatment with antibiotics and medical support. In the field observation in the area of home all the sick animals had hypernic moist eczematous lesion on whole body and tail, thighs, legs, udder, testicles at normal temperature and animals showing symptoms apitite.All were diagnosed with the syndrome endemic Eczematous wet and treatment were provided with alcohol antidegnala sulfate and Penta.

 

Literature Review:

Facial Eczema is a disease sheep and cattle produced in the warmer districts of the North Island late summer and autumn and is responsible for serious production losses in recent years. It is caused by a fungus, Pithomyces chartarum, which feeds on dead plant material in pasture under conditions wet. The spores of this fungus contain minutes essentially sporidesmin, which produces severe toxic effects in the liver. The appearance of the livers of animals affected varies depending on the severity of damage to small spots of light fade spots of serious distortions, and atrophy of large areas (Dr. Marjorie). Often severely damaged portions are surrounded by new liver tissue. Following damage to liver function are altered. The obstruction of the bile ducts may prevent the excretion of substances elimination in bile, for example, accumulation fat and bile pigment in the skin of the normal breakdown of old red blood cells, causing jaundice or yellow color frequently affected sheep carcasses. Of particular importance is the loss of the ability to excrete phylloerythrin substance. It is part of the digestive tract of ruminant degradation of chlorophyll and is absorbed in the intestine and liver, which are normally excreted in bile. If this mechanism of excretion is boring phylloerythrin in the blood that supplies the entire body (Norman Trevor). Phylloerythrin in a class of fluorescent pigments are able to make your sun-sensitive skin, causing redness, itching, swelling and crusting. These effects are, in general, showing the face of animals concerned, but also in the pigmentation of the skin exposed to light from others, such as nipples and udders of cows, which give rise to the appellation People's "facial eczema. These effects are skin, however, secondary to the most serious deficiency of fungi function.The liver Pithomyces chartarum, grows only in dead or dying plant tissues, not in the CV. Therefore, the amount of fungus in a pasture is related to some measures the amount of this dead matter, or garbage, now. The output growth of fungal spores and is strongly influenced by climate and environmental factors. Temperature, humidity, and the time that remains wet garbage seem particularly important. This explains the typical but not invariable, association disease with a period of warm and humid, often after a dry period during which growth has left the grass and accumulated waste in herbage.The poison sporidesmin, was isolated from cultures of the fungus and its chemical structure determined. A single dose of a thousandth gram is enough to kill a lamb of about 60 pounds vivo. Sporidesmin does not seem to accumulate in the liver, but its effects are cumulative, so that small doses repeated as effective as a single high dose. Even with a single dose, the full sequence of changes takes time to develop. Therefore photosensitization typically does not occur until 10 to 14 days after the animal received the toxin and may be further delayed. The chemical nature of sporidesmin and its effects on tissues that have unusual features that have not yet been fully studied.Facial eczema (FE) is a type of stroke Solaris (sometimes called photosensitivity), which affects exposed areas of skin Pale cattle. It is caused by a toxic substance called "sporidesmin" that attacks the liver. Sporidesmin occurs on pasture plants, including grass rye fungus called Pithomyces chartartum. This fungus is widespread and occurs naturally in dead plant material at the base of grass standing.
FE were recorded in sheep and cattle on the mainland of eastern South Australia. Deg Nala disease, which causes necrosis and gangrene of parties who rely on cattle and buffaloes (Bubalus bubalis) are known to exist in India and Pakistan, as a number of cases were derived from of the current monsoon rainfall in the region Murdike (Sheikhpura District) near Nala degrees in Pakistan (Shirlaw 1939). A widespread the disease has been reported in areas of rice cultivation in Indo-Pakistan (Irfan, 1971, Kalra et al. 1972; Irfan and Maqbool, 1986), which caused considerable economic losses.

Signs of illness

The disease can be seen in action several days to several weeks after collection sporidesmin pasture. The toxin is absorbed from the intestine and reaches the liver where they cause severe damage to bile ducts and cells liver. All signs FE external result of liver damage caused by sporidesmin.
Signs range from mild photosensitivity FE (sunburn) for severe jaundice and death depending on the quantity consumed sporidesmin. Sunburn is the most constant sign, and usually affects exposed areas Skin on the face, ears, nipples and the vulva, and areas of skin lacking dark pigmentation, ie. areas covered by white hairs. The skin on these areas becomes red, then goes crusty and dark. Over time, peel, leaving large raw areas which are susceptible to infection. Sunburn is often accompanied watery swelling of the underlying tissues. Jaundice (yellowing of mucous membranes) is often seen in this stage.Affected animals lose weight rapidly. Most animals recover from the acute phase, but tend to be stunted, which often takes several months to regain condition. Some never recover, and died or were been killed. In dairy cattle, udder and teats are often severely affected, and milk production decreases significantly. The weight loss and malaise are often grave and death, although rare, may occur even months after the initial liver damage occurs. The clinical symptoms are clumsiness initial lethargy and anorexia, the onset of jaundice and variable photosensitivity. Some pets may die without having been observed photosensitization: sheep - no wool skin including the nose, ears, face, arms of cattle - no black pigmented area including nipples, deer - widespread some animals develop chronic economy, some advances in blunt hepatic encephalopathy, tremors, depression, (lying Norman Trevor)

Epidemiology:

Factors animals. Sheep, cows, horses, deer sensitive resistant

Plant / environmental factors, fungi that grow on dead leaves grass, grazing is the perennial ryegrass most common but can occur in other species have need heat and moisture to promote rapid fungal growth and sporulation conditions typically involve autumn weather break after the summer rains, several days of constant heat (T ° C> 15.5 º C) and high humidity (> 80%) the toxin is concentrated in fungus spores that can be distributed on pasture for most toxic lawn grass sod is based.

Occurrence

Outbreaks often occur when the weather suitable for fungal growth and rapid production of spores are combined with abundant material dead, recently dead plant, which encourages growth fungi. The fungus requires warm weather and wet and light rain (or irrigation) for growth. This is most likely to be a problem in the fall when summer is hot and dry, heavy grass and eat again, and fall when the soil is still warm. In these conditions, the grass and the grass that grows quickly.
The fungus produces sporidesmin are not normally visible to the naked eye. It multiplies producing millions of spores which are coated with the toxin sporidesmin. Newly produced spores are the most toxic, and if growth stops after mushrooms climate change, the residual spores on pastures lose their toxicity within one or two weeks.

The fungus grows in most pastures plants, but grows best on grass. It grows on dead pasture litter at the base of plants. When the fungus reaches toxic levels, animals grazing short High rates of population density are at greater risk.

Treatment provided

The use of 5% alcohol Degnala Anti-5 to 19 ml S / C or I / m every two days 4 times a week was deemed successful. Or oral use of Penta-sulphate were given.

Conclusion:

The disease is closely linked to the feeding of rice straw containing multiple dark spots. This observation agrees with the conclusions of previous researchers (Irfan and Maqbool 1986) who reported that the infested straw mushrooms and mushroom carpet different species in different combinations, mixed with fresh non-rice straw infected, causing disease. Saprophytic fungi which infest the rice straw to produce mycotoxins vasoconstriction, which produces lesions of the disease, (Irfan al., 1984). The increased severity of disease in buffaloes from the cow may be partly due to the high sensitivity of this species. Therapeutic trials with an antidote (a mixture of penta-sulphate), being given orally, and a vasodilator (nitroglycerin ointment) for topical lesions in the highest percentage (90%) cure rate. This rate Healing is a broad agreement with the results of Schöntal (1980) who reported a cure rate of 80%, with a mixture of penta-sulphate. Even so on this observation, we observed whole animal was treated with an injection of anti-liquor Degnala penta sulfate followed heal completely. Similarly he had marked increases in total white blood cell count, and hemoglobin and hematocrit in the clinical phase of this syndrome on treatment had marked increase in both hematocrit and hemoglobin and increased erythrocyte count and WBC normal also support that this syndrome has been assigned by the infestation of mushrooms in the rice straw is fed to these animals. If the proper management of forage dry during the rainy season has taken place, can minimize the loss endemic to moist eczema syndrome. Further more, if the treatment timely animal is if you start using anti-alcohol Degnala or reduce sulfate penta minimum losses should be analyzed in
