What is Ciliate Fungus

Bacterial and viral infections are important factors that cause many diseases. Some pathogens are familiar to us, such as mycoplasma and chlamydia. But there are some things that many people don’t know much about. A typical one is ciliated bacteria, which can cause ciliated bacteria vaginitis, sepsis, etc. Understanding the situation of ciliated bacteria will help us deal with it better. So, what are cilia? Let’s take a look below.

Chinese name: Leptotrichia

Latin name: (Leptotrichia Trevisan, 1879)

Morphological description: straight rod or slightly curved rod, 0.5-1.5μm×5-15μm. Although young cultures may be Gram-positive, they are usually Gram-negative but have an atypical Gram-negative cell wall structure. It does not produce spores and does not move. It grows best when the gas phase contains 5% to 10% CO2. After multiple passages, some strains grew in an atmosphere containing CO2. The optimum growth temperature is 35-37℃, and it will not grow below 25℃. Chemo-organic nutrition, fermented carbohydrates, the main end product of fermented glucose is lactic acid. Lives primarily in plaque, but similar bacteria are also found in the female reproductive tract.

The G+C mol% of DNA is 25.

Type species (only one): Leptotrichia buccalis.

Cibotium vaginitis is a type of bacterial vaginitis caused by cibotium, which is mainly transmitted through sexual intercourse. The disease mostly occurs in young married women aged 20-30, with an incidence rate of about 20%.

Morphological characteristics of cilia

In each culture, many cells with pointed tips were usually visible. Two or more cells are arranged in aseptate mycelium of variable length. In old cultures, the filaments are up to 200 microns long and are surrounded by each other. In a filament, when the cells are lysed, large spherical bodies and swollen bubbles are sometimes seen. Does not form clubs or branches. The cells do not move. Cells cannot survive at 60°C for 10 minutes. It requires a heterotrophic life with complex nutrition, producing acid but not gas from glucose. The main product is DL-lactic acid, about 90%, acetic acid about 10%, and butyric acid is not a product.

It does not produce hydrogen sulfide and indole, and the catalase, benzidine and VP tests are negative. Nitrates are usually not reduced and gelatin is not liquefied. 5% CO2 is required for successful isolation and optimal growth. It grows well at 35℃ to 37℃, grows poorly or not at 25℃, and does not grow at 45℃. It mainly lives in plaques, but similar bacteria are also found in the female reproductive tract, which can cause ciliary vaginitis; it can also cause tissue necrosis and sepsis; it has recently been found that it can also cause intra-amniotic infection, and there are also reports of premature birth and tropical ulcers.
