What is gram variable bacilli?
Gram-variable bacilli are rod-shaped bacteria that do not consistently take up Gram stain, appearing either Gram-positive or Gram-negative under a microscope. This variability can result from factors such as the age of the culture, the composition of the cell wall, or the presence of certain conditions during staining. Gram-variable bacilli can include various species, some of which are pathogenic and associated with human diseases. Examples include certain strains of Corynebacterium and Mycobacterium.
Corynebacterium is a spore forming gram positive cocci?
Corynebacterium is a non spore forming gram positive cocci
Does levaquin treat gram positive cocci?
Yes, Levaquin (levofloxacin) is effective against a wide range of gram-positive cocci, including Staphylococcus aureus and Streptococcus pneumoniae. It is commonly used to treat infections caused by these bacteria.
Bacteria can be classified according to what three things?
cocci- which resemble sphers bacilli- which look like rods and spiralla- they resemble spirals
Is mycobacterium phlei gram positive or negative?
Although mycoplasma lack a cell wall and therefore test gram negative, they are considered to be descendents of 'nonsporulating and endospore forming gram-positive bacteria' (Madigan et al., 2009), such as Lactobacilli, Bacilli and Streptococci, (Dandekar et al., 2002), which have lost their cell wall. Mycoplasmas are therfore classed as gram- positive bacteria. This is supported by ribosomal RNA and DNA analysis.
What shape is Bacilli?
Bacilli are usually in rod shaped form. They can consist of gram negative and gram positive bacteria.
What Gram positive bacilli is nicknamed boxcars?
Bacillus anthracis is the Gram positive bacilli nicknamed "boxcars" due to its distinctive morphology resembling rectangular boxcars when viewed under the microscope.
What is the Normal result of vaginal gram stain?
many gram positive bacilli
You are positive for gram negative bacilli?
Gram-negative bacilli are a diverse group of bacteria that have a complex cell wall structure making them stain pink/red on a Gram stain. They include common pathogens like Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae. Identification of the specific type of gram-negative bacilli is important for appropriate treatment.
How gram positive bacilli defer from gram negative bacilli in gram stain?
First gentian violet or crystal violet solutn is applied,they bcome purple now iodine is added and acetone or ethyl alcohol is applied gram -ve bacteria lose their color while gram positive bacteria don't
Give the example for gram positivegram negative bacteria?
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
Does penicillin cure all infections and bacteria?
Penicillin is NOT effective against gram positive and negative cocci and gram positive bacilli only. it is not effective against rest of the organisms.

How do you treat bacilli?
Infections with B. anthracis can be treated with β-lactam antibiotics such as penicillin, and others which are active against Gram-positive bacteria. Penicillin-resistant B. anthraciscan be treated with fluoroquinolones such as ciprofloxacin or tetracycline antibiotics such as doxycycline.
Is herpes simplex gram positive or gram negative?
It is a pleomorphic Gram negative bacilli.
How do you get gram positive bacilli?
You do not " get " them, but gram positive bacteria are gram positive because their cell wall is of sufficient thickness and properly constructed to hold the Gram stain. They have one thick wall of peptidoglycan that holds the stain against being washed away. Gram negative bacteria have two thinner walls which allow the stain to be washed away, basically.
Corynebacterium is a spore forming gram positive cocci?
Corynebacterium is a non spore forming gram positive cocci
