了解运输拭子: 类型, 用途, 和主要区别

在微生物学和临床诊断领域, 运输拭子 play a crucial role in collecting, 保存, 并将标本从患者运送到实验室. 这些拭子通过防止运输过程中的污染和干燥来帮助维持微生物的活力, 确保测试结果准确.

运输拭子通常用于伤口采样, 喉, 鼻道, or other clinical sites when testing for bacterial or viral infections. Selecting the right 运输介质—such as 斯图尔特, 卡里-布莱尔, 或者 朋友们—is essential for maintaining specimen integrity until laboratory analysis.

What Is a Transport Swab?

A transport swab consists of two main parts:

1. Swab tip: Made from synthetic materials like rayon or nylon to collect samples effectively.
2. 传输介质: A semi-solid or liquid substance that preserves microorganisms by preventing their overgrowth or death.

These swabs come in various types designed to suit different transport conditions. Some are meant for aerobic organisms, others for anaerobic or fastidious bacteria.

Types of Transport Swabs

There are three major types of transport media commonly used in clinical diagnostics — 斯图尔特, 朋友们, 和 卡里-布莱尔. Each is formulated to support different specimen types and microorganisms.

1. 斯图尔特运输介质

这 Stuart medium is one of the earliest formulations used for specimen transport. It is a semi-solid, non-nutritive medium that preserves bacterial viability without promoting growth. Stuart transport swabs are suitable for specimens like throat, 伤口, and vaginal swabs.

Key Features:

• Contains sodium glycerophosphate as a buffering agent.

• Maintains bacterial survival for several hours.

• Ideal for aerobic and anaerobic bacterial samples.

2. 朋友运输媒介

这 Amies transport medium is a modified version of the Stuart medium with the addition of charcoal or other ingredients to neutralize toxic substances. Amies swabs are highly versatile and widely used in microbiology laboratories.

Key Features:

• Enhanced with charcoal to absorb fatty acids and toxins.

• Better recovery rate for fastidious organisms such as Neisseria Gonorrhoeae.

3. Cary-Blair 转运培养基

这 Cary-Blair medium is a semi-solid medium designed primarily for the transport of enteric pathogens such as 沙门氏菌, 志贺氏菌属, 和 Vibrio cholerae from stool samples.

Key Features:

• Maintains viability of intestinal bacteria.

• Ideal for fecal specimens and rectal swabs.

• Low nutrient content prevents overgrowth of non-pathogenic bacteria.

Applications of Transport Swabs

Transport swabs are used across various healthcare and diagnostic settings, 包含:

• Clinical diagnostics: for collecting throat, 鼻, 伤口, 阴道, and rectal samples.

• Public health surveillance: for detecting infectious diseases.

• Environmental testing: to monitor contamination in medical and food industries.

• Veterinary diagnostics: for collecting animal specimens.

Choosing the Right Transport Swab

Selecting the correct type of transport swab depends on the specimen and the target microorganism.

• 采用 斯图尔特 swabs for general bacterial culture.

• 选择 朋友们 swabs for fastidious organisms and wide-range transport.

• Select 卡里-布莱尔 swabs for stool and intestinal pathogen samples.

Proper storage and handling are essential to maintain specimen integrity. Always follow laboratory protocols and manufacturer instructions.
