概括

新生儿小牛腹 (NCD) 涉及多种病原体,而不仅仅是传统上公认的病原体. 与Cryptosporidium parvum结合的病毒感染是最常见的,这凸显了需要更广泛的诊断测试的需要.

背景情况:

新生儿小牛腹 (NCD) 是年轻小牛死亡的主要原因.
以前的研究往往只集中在特定或传统上公认的肠病原体上.
疫情通常涉及多种致病原体,使诊断和控制复杂化.

研究的目的:

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
