犬粪便产气荚膜梭菌携带率研究数据

产气荚膜梭菌是一种革兰氏阳性厌氧杆菌，被认为是一种常见的肠道病原体，可引发宠物不同程度的腹泻，甚至引发肠炎。产气荚膜梭菌可在人与宠物之间传播，影响人类健康。了解犬粪便中产气荚膜梭菌的携带率对于评估公共卫生风险具有重要意义，为疾病预防和控制提供科学依据，保障宠物及人类健康。犬粪便产气荚膜梭菌携带率研究还可以为流行病学的研究提供数据支持，有助于确定中国本土区域宠物产气荚膜梭菌的本底流行水平，为判断后续可能出现的异常流行情况提供基线参照。1、数据采集：从宠物医院收集一批犬粪便样本，按照1-500的顺序进行样本编号，记录取样时间并登记样品类型。2、数据检测：对收集到的501只动物粪便样本分别进行16S微生物测序，按照16S微生物测序数据分析流程进行数据分析，在属水平上统计产气荚膜梭菌检出量%，产气荚膜梭菌检出量%大于0的样本检测结果标记为阳性，等于0 的检测结果标记为阴性。3、数据处理：① 统计阳性总数，平均携带率=阳性总数/样本总数；② 平均携带丰度%=AVERAGE(产气荚膜梭菌检出量%)；③ 将产气荚膜梭菌检出量%按照从小到大的顺序排序，Q97.5=97.5%(n + 1)位置的检测数值，n为样本总数。4、数据应用：利用PYTHON收集群体样本产气荚膜梭菌检出量%，用MATPLOTLIB将该数据画出拟合图，便于研究人员观察分析。5、数据分类分级：将计算出的产气荚膜梭菌检出量%进行指标评价，分为“高、中、低“不同的类别和级别（产气荚膜梭菌检出量%值大于四分位数Q97.5的为“高”，大于0且小于等于Q97.5为“中”，值为0的为“低”）。

Clostridium perfringens is a Gram-positive anaerobic bacillus, recognized as a common enteric pathogen that can cause varying degrees of diarrhea and even enteritis in pets. It can transmit between humans and pets, posing a threat to human health.

Understanding the carriage rate of C. perfringens in canine feces is of great significance for assessing public health risks, providing scientific evidence for disease prevention and control, and safeguarding the health of both pets and humans. Research on the carriage rate of C. perfringens in canine feces can also provide data support for epidemiological studies, helping to determine the baseline prevalence level of C. perfringens in pets in local regions of China, and providing a baseline reference for identifying potential abnormal prevalence events in the future.

1. Data Collection: A batch of canine fecal samples was collected from veterinary hospitals. The samples were numbered sequentially from 1 to 500, with sampling time recorded and sample types registered.
2. Data Detection: 16S microbial sequencing was performed on all 501 collected animal fecal samples separately. Data analysis was conducted following the standard 16S microbial sequencing data analysis pipeline. The relative abundance (%) of C. perfringens at the genus level was calculated. Samples with a relative abundance of C. perfringens greater than 0 were marked as positive, while those with a value equal to 0 were marked as negative.
3. Data Processing: ① Count the total number of positive samples; the average carriage rate = total number of positive samples / total number of samples; ② The average carrying abundance (%) = AVERAGE(relative abundance of C. perfringens); ③ Sort the relative abundance values of C. perfringens in ascending order, where Q97.5 refers to the detected value at the position of 97.5%*(n+1), with n being the total number of samples.
4. Data Application: Python was used to collect the relative abundance data of C. perfringens from the cohort samples, and Matplotlib was employed to generate a fitted plot of the data, facilitating observation and analysis by researchers.
5. Data Classification and Grading: The calculated relative abundance values of C. perfringens were evaluated for indicator classification, divided into three categories and levels: "High", "Medium", and "Low". Specifically, samples with relative abundance greater than Q97.5 are classified as "High", those with value greater than 0 and less than or equal to Q97.5 are classified as "Medium", and those with a value of 0 are classified as "Low".
