Notes on some coccidia of peafowl,pheasants and chickens

The coccidium Isospora mayuri was isolated from sick peafowl on a farm in Essex (Great Britain). This is the first British record. The oocyst morphology and an unsuccesful attempt to infect chickens are described. The degree of pathogenicity is uncertain. Oocyst production might be controlled by sulphaquinoxaline and diaveridine in the drinking water but further studies are necessary.The coccidia Eimeria phasiani, E. duodenalis and E. colchici were isolated from pheasants on an Essex estate over two years. Coccidiosis due to E. colchici in intensively raised pheasants was controlled by sulphaquinoxaline and diaveridine in the drinking water.Two attempts were made to infect pheasants with the chicken coccidium E. tenella using birds raised coccidia-free in cages. The pheasants showed no signs of infection, which contradicts the conclusions of previous authors based only on field studies.     

Description of Eimeria pavonina (coccidia) of peafowl in Germany

There are only a few reports about the occurrence of coccidia in peafowl and no reports about the occurrence of Eimeria spp. in peafowl kept in Europe. Here, we describe the occurrence of Eimeria pavonina in diseased peafowl from Germany. In January 2011, one young peacock kept in an aviary showed a marked depression. No parasites were detected in samples from the diseased bird, but in samples of birds from the same and other aviaries, coccidian counts were between 400/g and 66,000/g. All peacocks were treated with toltrazuril. After treatment, the clinical condition of the diseased bird improved but, two weeks afterwards, other birds in the aviary were still shedding coccidia in their feces. Based on morphology, the coccidia were identified as E. pavonina. Parts of the 18s rRNA gene and the cytochrome oxidase subunit 1 (cox-1) gene were sequenced. A phylogenetic tree based on the 18s rRNA sequence placed the Eimeria sp. from peafowl closest to Eimeria spp. found in pheasants and partridges as well as to Eimeria meleagrimitis. A phylogenetic tree based on the sequence of cox-1 in contrast suggested a closer relationship to Eimeria necatrix and Eimeria tenella.

The coccidia of sheep and goats in Senegal

A survey of the coccidia in domestic sheep and goats was undertaken to ascertain the type of Eimeria species and the number of different coccidial species in individual faecal samples. Simultaneously the prevalence and the oocyst output was investigated in 2234 sheep and 577 goats during a 12-month period. Eight Eimeria species were encountered in sheep: E. ahsata, E. crandallis, E. faurei, E. intricata, E. ovina, E. ovinoidalis, E. pallida and E. parva.

In goats the following species were found: E. ahsata, E. arloingi, E. christenseni, E. crandallis, E. faurei, E. intricata, E. ninakohlyakimovae and E. parva.

The prevalence in sheep was 94% and in goats 85%, multiple parasitism was the rule. No seasonal fluctuation was observed in the prevalence or oocyst output. The sheep and goats' oocyst output was moderate, the mean for both being in the range of 1000–5000 oocysts/g of faeces.     

阿德呋啉对球虫耐药株的疗效

观察阿德呋啉对巢湖、霍邱、定远3地球虫的治疗效果及雏鸡增重的影响。结果显示巢湖株中,氯羟吡啶组抗球虫指数（ACI：anti—coecidialindex）值为183．26,敏感,其余组均完全耐药;霍邱株中,妥曲珠利组ACI值为180．48,敏感,其余组呈部分或完全耐药;而定远株对5种抗球虫药均不敏感。与阳性对照组相比,除霍邱株拌料给药组外,其余阿德呋啉给药组ACI值均高于180,对三地鸡球虫病均有良好的疗效;与对照组相比,巢湖和定远株感染组中拌料给药组增重效果明显,饮水给药组次之,而霍邱株均接近阴性对照组,且阿德呋啉给药组的饲料转化率均高于对照组。试验结果表明：3种虫株对试验所用5种抗球虫药已形成交叉或多重耐药,阿德呋啉对上述虫株有较好的抑杀效果,且具有促生长作用。
