Animals, Domestic: Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including Livestock (specifically Cattle; Sheep; Horses; etc.), Poultry; and those raised or kept for pleasure and companionship, e.g., Pets; or specifically Dogs; Cats; etc.

The quality of water destined for use in agricultural, recreational, and domestic settings is of great importance due to the potential for outbreaks of waterborne disease. Microbial agents implicated in such events include parasites, bacteria, and viruses that are shed in high numbers in the feces of infected people and animals. Transmission to new and susceptible hosts may then occur via the fecal-oral route upon ingestion of contaminated water. Therefore, the ability to monitor water sources for the presence of pathogenic microorganisms is significant in order to ensure public health. Due to the sheer number and variety of potential fecal-oral pathogens that may be present in water and their variable concentrations, it is impractical and expensive to assay directly for each one of them on a regular basis. Therefore, the microbiological assays for water quality monitoring employ coliform indicator bacteria. Coliforms comprise, in part, the normal intestinal microflora of warm-blooded mammals, are non-pathogenic, and are consistently excreted in the feces. Therefore, the detection of coliform bacteria in water means that a fecal release occurred, and that harmful pathogenic m

Viruses are a unique group of biological entities that infect both eukaryotic and prokaryotic organisms. They are obligate parasites that have no metabolic capacity, and in order to replicate, rely on host metabolism to produce viral parts that self-assemble inside host cells. Viruses are ultramicroscopic—too small to be viewed with the light microscope, visible only with the greater resolution of the electron microscope. A viral particle consists of a nucleic acid genome, either DNA or RNA, surrounded by a protein coat, known as a capsid, composed of protein subunits or capsomers. In some more complex viruses, the capsid is surrounded by an additional lipid envelope, and some have spike-like surface appendages or tails. Viruses that infect the intestinal tract of humans and animals are known as enteric viruses. They are excreted in feces and can be isolated from domestic wastewater. Viruses which infect bacteria are known as bacteriophages, and those which infect coliform bacteria are called coliphages (Figure 1). The phages of coliform bacteria are found anywhere coliform bacteria are found.

Breast exams are a key part of an annual gynecological exam and are important for all patients, no matter their sex or gender expression. One out of every 8 women will be diagnosed with breast cancer; male breast cancer, though less common, has a lifetime incidence of 1 in 1000. Breast exams can feel invasive to patients, so it is important to do everything possible to make the patients feel comfortable and empowered, rather than vulnerable. Examiners should be aware of what they are communicating, both verbally and non-verbally, and give their patients control wherever possible (for instance, always allowing them to remove their own gowns). Examiners may choose to utilize chaperones for the patients' (as well as their own) comfort. Some institutions require the use of chaperones. While it is always important to avoid overly clinical language, certain colloquial words can cross the line from caring to overly intimate in this exam. It is helpful to avoid the words "touch" and "feel" in this exam, as this lan

The pelvic exam can feel invasive to patients, so it is important to do everything possible to make patients feel comfortable and empowered, rather than vulnerable. Clinicians should be aware of how they are communicating, both verbally and nonverbally, and should give their patients control whenever possible. There are many ways to do this, from how the exam table is positioned to how the patient is engaged throughout the exam. As many as 1 in 5 patients may have experienced sexual trauma; therefore, it is important to avoid triggering those patients, but it's not always possible to know who they are. The exam in this video demonstrates neutral language and techniques that can be employed with all patients to create the best experience possible. It's important to keep the patient covered wherever possible and to minimize extraneous contact. A clinician should be careful to tuck fingers that aren't being used to examine the patient to avoid accidental contact with the clitoris or anus. Before performing the pelvic e
