- 公共卫生 公共卫生
背景情况:
- 塔霍边缘小径 (TRT) 是一个受欢迎的休区,强调需要评估其水源的安全性.
- 致病微生物如大肠杆菌,吉亚迪亚和杆菌通过污染的水对人类构成潜在的健康风险.
研究的目的:
- 估计TRT沿线河流中关键的水源病原体的污染水平.
- 为了评估大肠杆菌,Giardia和Cryptosporidium spp.的存在和度. 在TRT的水源中.
主要方法:
- 在2023年夏季和秋季初,从TRT的6个段收集了水样.
- 大肠杆菌被用标准方法9223B量化.
- 吉亚迪亚和Cryptosporidium spp. 的种类. 使用EPA方法1623进行检测.

Sputum Studies I: Gram Stain, cytology, and Acid-fast smear and culture
Sputum studies are a critical part of diagnosing and treating numerous respiratory conditions. These studies involve obtaining sputum samples for analysis to identify pathogenic organisms and assess the presence of abnormal cells indicative of malignant conditions. This lesson will delve into three fundamental sputum studies: Gram Stain, Cytology, and Acid-fast Smear and Culture.

Freshwater Microbial Ecology
Freshwater systems such as streams, rivers, and lakes exhibit distinct physical and biological characteristics that influence their microbial communities. These environments are broadly categorized into lotic systems—those with flowing waters like streams and most rivers—and lentic systems, which include still or slow-moving waters such as lakes, ponds, and marshes.In lentic systems, phytoplankton drive primary production, generating autochthonous organic carbon. In contrast, lotic systems...
