The research has revealed the invasion agents like: Eimeria perforans, E. magna, E. stiedae in rabbits and nutrias, in a small amount– E. coecicola, E. pisiformis and E. intestinalis in rabbits, Е. maxima, E. tenella, E. necatrix and E. acervulina in chickens and quails. Rapidly infected fur animals (280 rabbits and 180 nutrias), 3468 chickens and 1800 quails were examined while conducting a research. Under the localization of a path-alogic process, the disease appeared in poultry in a mixed pattern; in rabbits and nutrias in an intestinal pat-tern (11.9 % and 11 %), in a hepatic pattern (8.1 % and 11 %) and mostly in a mixed pattern (80 % and 78 % respectively). The research showed that sick rabbits and nutrias were weak, mucous membranes of eyes and nose were pale (50.5 and 49 %), yellowish (38 and 42 %). Occasional watery feces (80 and 91 %), flatus were observed, the abdomen was increased and infirm (87.1 and 85 %). Under complications the rabbits had intermittent fever (5%), acute bouts of cramps (7.14 %). Death was observed in rabbits under a severe disease in two weeks time (10%) and in nutrias in 3-5 weeks (7%). Digestive unsets were a characteristic feature under an asymptomatic disease course. From among the blood biochemical indices of nutrias and rabbits, a decrease in the count of hemoglobu-line, in the amount of albumen, crude protein as compared to a control group was registered. A depressed state, thirst, (27th day), 1-2 ºС temperature rise, drowsiness, awkward gait (35th day), watery feces, feces with blood admixtures were registered in chickens, and the quails manifested unwillingness to eat, gathered in warm places, they also had white-and-green watery feces, labored respiration and accelerated cardiac rate. Some decrease in the amount of red blood cells, pseudoeosinophils as well as some increase in the amount of white blood cells and eosonophils were registered in the blood of sick chickens and quails. Some decrease in the count of hemoglobulin, in the amount of creatinine and urine was registered in blood serum of the infected chickens and quails. Thus, some changes in blood indices of chickens and quails which suffered from protozoal invasion testi-fied to a toxic and trophic effects of eimerias and their metabolites on the organisms.

La alta prevalencia de eimeriosis, en el ganado vacuno, altos costos de fármacos, baja efectividad, toxicidad a altas dosis, presencia de residuos en leche y carne, deterioro del medio ambiente, son factores que limitan al pequeño productor para controlar la enfermedad; el presente trabajo de investigación se realizó en el sector Huacariz, distrito y provincia Cajamarca, Región Cajamarca, Perú; en los meses de julio - agosto del año 2013, se evaluó la eficacia del pulverizado de Lobelia decurrens Cav. (Contoya), en el control de Eimeria sp., en 18 terneras de 3 a 6 meses de edad, raza Holstein, criados en un sistema semi intensivo, se aplicó diseño experimental dos tratamientos (T1), (T2) y un control (T0), con seis unidades experimentales cada uno, distribuidos homogéneamente de acuerdo a la carga parasitaria de opgh; al grupo T1, se le administró la dosis de 1 g/kg pv, al grupo T2, se administró 2 g/kg pv; realizando análisis coproparasitoscópico mediante la técnica de Mc Master a 3, 17 y 21 días pos tratamiento. Los resultados mostraron, eficacia de 38,04 %, 68,32 % y 80,8 % para 1 g/kg pv, a nivel de confianza de P < 0,05 y una eficacia de 73,91 %, 78,26 % y 92,6 % a dosis de 2 g/ kg pv, a nivel de P < 0,05 de confianza; se concluye que la contoya a 2 gramos/kg pv, a los 21 días pos dosificación alcanza la eficacia de un anticoccidiano eficaz.

A cama de aviário pode causar contaminação ambiental pelo excesso de nutrientes, microorganismos patogênicos e resíduos químicos. Para minimizar estes impactos pode-se fazer compostagem da cama de aviário antes de sua aplicação como fertilizante, porém, ainda existem muitas dúvidas sobre a eficiência deste tratamento. O objetivo deste trabalho foi analisar a persistência de patógenos e do antibiótico salinomicina em cama de aviário submetida à pilhas estáticas de compostagem. Os três tratamentos usados foram: CSC (cama de aviário com camadas de solo e coberto com capim) CP (cama de aviário coberta com polietileno) e CCC (cama de aviário com camadas de capim e coberto com capim). Acompanhou-se a evolução da temperatura nas pilhas, pH, níveis de Escherichia coli, oocistos de eimérias e concentrações do antibiótico salinomicina. O tratamento CP foi o menos eficiente na degradação do antibiótico salinomicina até os 90 dias. A compostagem da cama de aviário, independente dos tratamentos, é eficiente na eliminação de E. coli. The high concentration of poultry litter in some regions has caused environmental pollution because of excess of nutrients, pathogenic microorganisms and chemical residues. In order to minimize these impacts, the producers have been stimulated to composting the poultry litter before its application as a fertilizer, however there are many doubts concerning the efficiency of this treatment. The goal of this research was analyse the persistence of pathogens and the salinomycin antibiotic in unturned static composting piles of poultry litter. The three used composting treatments were: CSC treatment (poultry litter with soil layers and covered with grass), CP (poultry litter covered with polyethylene) and CCC (poultry litter with grass layers and covered with grass). It was attended the evolution of the temperature of the layers, humidity, Escherichia coli level, oocysts of Eimeria and concentrations of salinomycin antibiotic until 90 days. The CP treatment is less efficient for degradation of the salinomycin antibiotic. Independent of the treatments, the composting of poultry litter is efficient in elimination of E coli.
