L-form bacteria are distinct from mycoplasmas, because Mycoplasma spp. do not originate from bacteria that normally possess a cell wall. A huge variety of gram-positive and gram-negative bacterial species may become CWDB when exposed to certain stressors in the laboratory (such as antimicrobial drugs) (Box 39-1).

L-forms are “cell wall-deficient” bacteria which are able to grow as spheroplasts or protoplasts. They can be differentiated into four types depending on their ability to revert to the parental, cell-walled form and to the extent of their cell-wall modification.

: a small variant form of some bacteria (as those causing anthrax, Lyme disease, and tuberculosis) that typically lacks a cell wall and displays resistance to antibiotics.

Almost all bacterial cells in their normal walled state divide by binary fission via a complex protein-based FtsZ division machinery [3]. Instead, L-forms proliferate by a range of poorly regulated shape perturbations, including blebbing, tubulation and vesiculation [20,58–60] (figure 1).

These cell walls are often the target for many antibiotic treatments. L-form bacteria are strains of bacteria that lack a cell wall. They are typically found a spheres or spheroids.

A urinary tract infection causes the lining of the urinary tract to become red and irritated (inflammation), which may produce some of the following symptoms:

• Pain in the side (flank), abdomen or pelvic area.
• Pressure in the lower pelvis.

Antibiotics are an effective treatment for UTIs. However, the body can often resolve minor, uncomplicated UTIs on its own without the help of antibiotics. By some estimates, 25–42 percent of uncomplicated UTI infections clear on their own.

Symptoms of UTIs

• A burning feeling when you pee.
• A frequent or intense urge to pee, even though little comes out when you do.
• Cloudy, dark, bloody, or strange-smelling pee.
• Feeling tired or shaky.
• Fever or chills (a sign that the infection may have reached your kidneys)
• Pain or pressure in your back or lower abdomen.

Do antibiotics for a UTI require a doctor’s visit or prescription? Antibiotics are not available without a prescription in the United States. You will need to talk to a doctor or nurse practitioner to get a prescription. You can do this in person, over the phone, or over video.

Some pharmacies offer a UTI management service and can prescribe antibiotics if they’re needed.

Drugs commonly recommended for simple UTIs include:

• Trimethoprim/sulfamethoxazole (Bactrim, Septra, others)
• Fosfomycin (Monurol)
• Nitrofurantoin (Macrodantin, Macrobid)
• Cephalexin (Keflex)
• Ceftriaxone.

Urinary tract infection (UTI) A bladder infection or other infection impacting the urinary tract can lead to urine that smells like ammonia. Other symptoms associated with a UTI include: pain when urinating.

Most changes in urine odor are temporary and don’t mean you have a serious illness, particularly if you have no other symptoms. When an unusual urine odor is caused by an underlying medical condition, other symptoms are also present. If you’re concerned about the odor of your urine, talk to your doctor.

Urochrome can be amber in color, but when you drink enough water, the amber color gets more dilute and appears yellow. Ideally, your urine will appear yellow or straw-colored. If it’s so light it’s almost clear, you may be drinking too much. If it’s darker, you may not be drinking enough.

Amber urine Amber urined your bright yellow or neon liquid. Bright yellow urine is harmless, and is just a sign that you are taking more vitamins than your body needs. You may want to check with your doctor on what vitamins your body does not need as much of so you can cut back.

Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is. Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color.

Dehydration occurs when you don’t drink enough fluids. If you’re dehydrated, you may notice that your urine is a dark yellow or orange color and smells like ammonia. Most people only experience minor dehydration and don’t require medical treatment.

Things you can try at home:

1. Wear underwear made of natural materials, such as cotton or moisture-wicking fabrics.
2. Wear loose-fitting boxers.
3. Shower twice daily.
4. Apply cornstarch to help control moisture and odor.
5. Avoid spicy foods, caffeine, and alcohol.

Clear urine is a sign of good hydration and a healthy urinary tract. However, if they consistently notice clear urine and also have extreme or unusual thirst, it is best to speak to a doctor.

For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times a day can also be normal if that person is healthy and happy with the number of times they visit the toilet.

When you are drinking enough fluids your body is in balance and your urine will be a pale straw yellow colour. When you have not drank enough fluids your kidneys try to save as much water as they can and cause your urine to be darker in colour (more concentrated).

The color of your urine is one of the most reliable indicators of your body’s level of hydration. If you’re dehydrated, the contents of your toilet bowl will be a dark yellow. When you’re properly hydrated, it will range from light yellow to fully clear.

PEEING ONCE OR TWICE A DAY: Peeing once or twice a day is not a healthy symptom. This means that you are dehydrated and your body requires water to eliminate toxins and waste out of it.

Because people tend to sleep for several hours without having a drink, their urine is normally darker when urinating first thing in the morning. Darker urine during the day or evening may be one of the signs that someone is dehydrated meaning they are not drinking enough fluids.

Morning is when your urine will be most concentrated. So, if your morning urine is a pale, straw color, you’re probably well hydrated and healthy. At bedtime, it should look as clear as water or at least pale yellow. If it doesn’t, you may need to boost your fluid intake.

When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple. The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts.

Pregnancy. Anecdotal evidence suggests that bright-yellow urine may be an early symptom of pregnancy.
