I am a rod-like bacterium but my appearance is not constant; I may be short
or long. I am pink when stained by Gram stain. I am sometimes covered by a protective coat. I love blood but can't
grow on plain blood agar. I grow better when kept in a candle jar. I can turn
oxidase paper purple. I satellite around Staphylococcus aureus colonies. I cause
serious illness in children and young adults like meningitis, otitis media,
croup etc. Who am I?
If you know me, find me in this list.
I am a rod-shaped bacterium and I move around with aid of numerous flagella. I appear pink on Gram staining.
I live in people's gut but usually don't harm them. I am not very particular about my
diet and can grow on any medium. On MacConkey's agar I produce pink coloured
colonies. I don't lyse red blood cells. Some members of my kind are virulent and
can cause diarrhea and dysentery in children and adults, some cause
urinary tract infection and some others cause meningitis of the new born. I
can cause various types of illness. I am becoming well known for my ability to
share plasmids coding for antibiotic resistance. Who am I?

I am a rod-shaped bacterium. I appear pink upon Gram staining. I am part of a big family and my species
consists of thousands of members antigenically different from each other. I am
sometimes protected by a coat, my cell wall and flagella are antigenically
variable. I can move around using my multiple flagella. I can't ferment lactose
in the MacConkey's agar but I can produce a little H2S. When I
ferment glucose, I don't produce any gas. I infect people when they ingest me, I
go through their intestine to blood and multiply in liver, spleen and get back
to blood. I love bile and reside in the gall bladder, from here I go back to the
intestine and cause ulcers. Sometimes I stay in the host for long time without
the host's awareness. Who am I?

I am spherical in shape but you will find me in grape-like clusters. I appear violet on Gram staining. My
colonies have distinct golden-yellow colour. I can grow on ordinary medium but
grow best on medium with blood. I can completely lyse red cells. I can gel human
or rabbit plasma in a test tube. I am a nasty
bug, I can survive in hospital environment and I readily colonize people in the
hospitals. I have a huge arsenal of toxins and enzymes can cause variety of
illness ranging from boils to toxic shock syndrome. I can destroy penicllin
using my enzymes and some of my kind are resistant to multiple antibiotics
making it difficult to kill us. Who am I?

I am a solitary rod-shaped bacterium. I appear pink on Gram staining. I have no flagella and can't move
around. I am a part of the large family but none of my species can ferment
lactose. When I ferment glucose, I don't produce any gas. I don't ferment
mannitol whereas other members of my species can. I infect people when they
ingest me. Only a few of us are enough to produce dysentery in the host. I
produce a potent toxin that has neurotoxic, cytotoxic and enterocytoxic
property. Who am I?

I am always found in pairs, sometimes the pair appear as short chains. I am
protected by a coat that can swell in the presence of specific antiserum. I am
not exactly spherical but more lanceolate with sides facing each other being
more rounded. I can't survive on simple nutrition and presence of blood boosts
my growth. I can lyse blood but only partially. I grow better in a candle jar.
As I grow old, I become suicidal. My colonies may have central depression and
may appear like carom coin. I don't froth in H2O2.
Sometimes people carry me in their throat and I often infect their lower
respiratory tract. I can infect lungs, middle ear, and even brain. Who am I?
