The most common cause of abnormal vaginal odor is high levels of Gardnerella vaginalis bacteria, which cause the fishy smell associated with BV. As part of the diagnosis, your provider may also: Take a medical history and ask about your symptoms.
Bacterial vaginosis (BV) is a common vaginal infection that happens when some normal bacteria that live in your vagina overgrow, causing a bacterial imbalance. Symptoms include an off-white or gray vaginal discharge that smells “fishy.” BV is easily treatable with antibiotics from a healthcare provider.
Bacteria in the stomach produce trimethylamine from the precursors of trimethylamine-N-oxide and choline. It has a fishy odor, but it is typically converted back into trimethylamine in the liver by an enzyme's actions.
3-methyl-3-sulfanylhexan-1-ol (3M3SH) is a thioalcohol, produced by Staphylococcus hominis, which makes the underarms smell like rotten onions or meat.
If a person's body has a fishy smell, they may have trimethylaminuria. This is a genetic rare disorder in which the body cannot break down the chemical trimethylamine. It is sometimes called fish odor syndrome. Trimethylamine has a very strong smell, similar to that of rotting fish.
Bacterial Vaginosis (BV) is one possibility. BV is a bacterial infection that occurs when your healthy lactobacilli get out of balance and grow too much. Symptoms include thin vaginal discharge that has a strong fishy smell and a little itching or burning when you urinate. BV is treated with an antibiotic.
A Fishy Smell
The smell can come from loose or frayed wires or cords, overloaded circuits, faulty outlets, incorrectly sized breakers or fuses, or overheated electrical shielding or insulation. If they are not addressed quickly and properly, these problems could result in a house fire.
You may suspect that your problem with your water is caused by E. coli, if you notice one or more of these warning signs: The water has an odor that is not chemical in nature, but appears earthy, musty, sulfur-like, sewage-like, or generally unpleasant.
Streptococcus anginosus may be beta-hemolytic or nonhemolytic. The small colonies often give off a distinct odor of butterscotch or caramel.
Pseudomonas aeruginosa has a characteristic sweet, fruity odour due to its production of trimethylamine. This organism also produces the greenish-blue pigment pyocyanin, which diffuses into the undersurface of the nail plate, accounting for the green discoloration characteristic of this condition.
Food that is contaminated with Salmonella or other harmful germs usually looks, tastes, and smells normal. That's why it's important to know how to prevent infection. Salmonella cause far more illnesses than you might suspect.
However, an unpleasantly smelly odor can be a sign of an infection that needs to be treated right away, especially if it's accompanied by an unusual discharge. A strong fishy smell that won't go away is worth seeing a health care provider about.
Symptoms of bacterial vaginosis include: an unusual vaginal discharge that has a strong fishy smell, particularly after sex. a change to the colour and consistency of your discharge, such as becoming greyish-white and thin and watery.
Why does my boyfriend keep giving me BV? Bacterial vaginosis is caused by a change in the natural balance of bacteria in your vagina. For some people, exposure to semen can alter the bacteria in your vagina and cause BV. If this applies to you, using a condom can help reduce the risk of recurring BV.
Douching, not using condoms, and having new or multiple sex partners can upset the normal balance of vaginal bacteria, increasing your risk for getting BV.
Escherichia coli has a distinct fecal odor. Then there are the staphylococci. Staphylococcus aureus smells like decomposition while S. epidermis smells like old sweat.
Sense of smell in humans has the capacity to detect certain volatiles from bacterial infections. Our olfactory senses were used in ancient medicine to diagnose diseases in patients.
“Just by moving the gene in, we got Staphylococcus aureus that made body odour,” Thomas said. “Our noses are extremely good at detecting these thioalcohols at extremely low thresholds, which is why they are really important for body odour. They have a very characteristic cheesy, oniony smell that you would recognise.
Particularly, isolates of Klebsiella and Enterobacter have been found to emit foul odors in vitro that resemble bad breath, with concomitant production of volatile sulfides and cadaverine [5].
coli (STEC) infection vary for each person, but often include severe stomach cramps, diarrhea (often bloody), and vomiting. Some people may have a fever, which usually is not very high (less than 101˚F/38.5˚C).
Fishy smell in house
This could be a sign that an electrical fixture, likely an appliance, in your home is overheating. The “fishy” or potentially acrid smell may mean that the plastic, rubber, or another material around the afflicted appliance is melting. If you ignore this for too long, it could cause a fire.
An electrical component may be overheating.
If the insulation is damaged or the wiring is experiencing electrical surges from a faulty breaker, the heat generated by the electricity can begin to melt the plastic, which is often identified as a fishy odor.
