摘要

Prototheca spp. are unicellular and ubiquitous algae that can cause mastitis in dairy cows. Different Prototheca spp. have been identified including P. wickerhamii, P. stagnora, P. ulmea, P. zopfii, P. blaschkeae, and P. cutis sp. novum. The species P. zopfii is further differentiated into P. zopfii genotype 1 and P. zopfii genotype 2. P. zopfii genotype 2 and P. blaschkeae have both been associated with bovine mastitis (Aouay et al., 2008), whereas P. zopfii genotype 1 is usually not associated withnaturally occurring mastitis. Unfortunately, mastitis associated with Prototheca spp. is not curable with any available medication. Therefore, to prevent the disease from further spread within the herd it is necessary to rapidly identify infected cows.A study by Tenhagen and others (1999) in a large German dairy herd found that cows with a higher lactation number and individual cow somatic cell count (SCC) during lactation were at greater risk for getting an infection with Prototheca spp.

P.Zopfii基因型2和P.Blaschkeae都与牛乳腺炎（Aouay等，2008）相关，而P. Zopfii基因型1通常不相关出现乳腺炎。不幸的是，与Prototheca SPP相关的乳腺炎。不可用任何可用的药物治愈。因此，为了防止疾病进一步蔓延到牛群中，有必要快速识别受感染的奶牛。由Tenhagen和其他人（1999）在一个大型德国乳制品牛群中发现，发现母猪具有更高的哺乳期和个体牛体细胞计数（SCC）在哺乳期间对患有Prototheca SPP感染的风险更大。
