Atypical coccidiosis in South American camelids.

Reported clinical signs of coccidiosis in South American camelids include anorexia of a few days duration, sudden death, and diarrhea. Antemortem diagnosis of clinical coccidiosis is usually based on clinical signs and supported by detection of coccidial oocysts in feces. This report describes 2 atypical cases of coccidiosis in South American camelids that had no coccidial oocysts detected on antemortem fecal flotation, prolonged weight loss, and normal fecal consistency.     

Efficacy of diclazuril in the prevention and cure of intestinal and hepatic coccidiosis in rabbits

The efficacy of diclazuril against intestinal and hepatic coccidiosis was studied in artificially infected rabbits. Prophylaxis against intestinal coccidiosis was evaluated using a mixed infection of Eimeria intestinalis, Eimeria magna and Eimeria perforans. Continuous medication in the feed at 1 p.p.m. was 100% effective in reducing oocyst output and faecal scores, and weight gain and feed efficiency were normal. Hepatic coccidiosis induced by Eimeria stiedai was prevented at 0.5 and 1 p.p.m. as shown by negative oocyst counts, normal liver weight, absence of liver lesions, and normal body-weight gain and feed efficiency. Medication at 1 p.p.m. for 7 consecutive days during the prepatent phase of hepatic coccidiosis resulted in large reductions in oocyst counts and lesion scores with a normal liver weight and growth performance. Diclazuril at 1 p.p.m. in the feed prevented both intestinal and hepatic coccidiosis in rabbits and can be advocated for safe mass medication.

肉鸡球虫病控制方法现状

Happily, I can say that we have more approaches to coccidiosis control than ever before.Unfortunately,coccidiosis still is and will continue to be a major concern both in bird health and economics. The main reasons coccidiosis is still a problem include : 　　1. Our inability to manage all factors that contribute to the incidence of coccidiosis. 　　……     

An unusual case of coccidiosis in laboratory-reared pheasants resulting from a breach in biosecurity

An outbreak of coccidiosis in laboratory-reared Chinese ring-necked pheasants (Phasianus colchicus) resulted in high morbidity and moderate mortality. The outbreak was associated with a breach in biosecurity caused by the cleaning of a sewer line with a mechanical device, resulting in extensive splattering of fecal material throughout the "clean room" where birds were held prior to use in coccidiosis experiments. Mortality and morbidity in the affected birds were seen exactly 5 days after the incident, after birds had been moved to another room for experimental use, corresponding closely with the known prepatent or preclinical period of Eimeria phasiani and Eimeria colchici. Gross lesions in the affected birds varied from dehydration to intestinal and ventricular hemorrhage. Microscopic examination confirmed a diagnosis of severe intestinal coccidiosis. This report underscores the ease of contamination of experimental birds leading to coccidiosis outbreaks during breaches of management and biosecurity.

Study on Coccidiosis of Scavenging Indigenous Chickens in Central Ethiopia

An investigation was made into coccidiosis of 190 scavenging indigenous chickens between September 2000 and April 2001 in three selected agroclimatic zones, in central Ethiopia. This was done through clinical, postmortem and microscopic examinations. Data were processed by chi-square and Mantel-Haenzel test. The study indicated that 25.8% (49/190) of the chickens were infected with coccidiosis and found to harbour one to four different species of Eimeria. Of these infected chickens, 30 (15.8%) and 19 (10.0%) were positive for clinical and sub-clinical coccidiosis, respectively. There was a significant altitude difference (chi2 = 14.7, p <0.001) in coccidiosis prevalence: 42.2% in chickens from highland region followed by 21.5% in mid-altitude and 13.1% in low-altitude areas. When quantified, the prevalence of coccidiosis was 2.66 and 4.83 times higher in the high-altitude than in mid-altitude (odds ratio, OR = 2.66, p<0.05) and low-altitude (OR = 4.83, p<0.001) chickens. The pathogenic Eimeria species responsible for clinical coccidiosis were E. necatrix, E. acervulina, E. maxima and E. tenella. With increasing demand for poultry products in developing countries, knowledge of production constraints in traditional management practices could help devise control strategies for constraints on backyard poultry production systems.     

Effect of Sulfakombin SPOFA on the dynamics of the extent of coccidiosis in small rabbit breeding operations

We determined the yearly changes in coccidiosis extensity applying the results of an examination of 2707 rabbits performed in the years 1981-1984. A field trial was conducted to study the efficiency of the Czechoslovak anticoccidic drug Sulfakombin Spofa administered to control coccidiosis in small rabbit breedings. We made the calculations to find out the optimum time of administration of sulphonamide substances. We discuss certain factors that influence in a decisive way the changes in coccidiosis extensity in rabbit breedings.
