Enterobius vermicularis, also known as pinworm, is a common intestinal parasite that infects humans. These worms are small, about 1 cm, are white or translucent in color. They are easily visible to the naked eye and can sometimes be seen moving around the anal area.
The video shows a moving Enterobius vermicularis worm with its distinctive cylindrical shape and tapered end. The worm moves by contracting and relaxing its muscles in a wave-like motion, allowing it to crawl or wriggle forward.

Breakpoints for gentamicin, tobramycin, and amikacin are based on population distributions of various species, PK/PD target attainment analyses with an end point of net bacterial stasis and limited clinical data.

Clinical outcomes data for aminoglycosides as MONOtherapy for systemic infections are limited and have resulted in worse treatment outcomes (for infections outside of the urinary tract) compared with other therapies.

Echinococcosis or hydatid disease is caused by the larval stage of the dog tapeworm, Echinococcus granulosus. The definitive host for this disease is the dog or other canids and the intermediate hosts are cattle,sheep,pigs,goats or camels. Man is an accidental intermediate host
Hydatid disease in humans is potentially dangerous depending on the location of the cyst. Some cysts may remain undetected for many years until they become large enough to affect other organs. Symptoms are then of a space occupying lesion.

Yeast will grow on bacteriological media (sheep blood agar and chocolate agar).
They may appear as small, creamy or white colonies that are somewhat more raised than staphylococcal colonies.
They may appear as small, creamy or white colonies that are somewhat more raised than staphylococcal colonies.
A presumptive identification of C albicans can be made by observing pasty,yellow-white colonies from which colony projections, often referred to as "feet," extend out from the margins.
These feet have typically been considered a characteristic of C albicans

India ink preparation of CSF from a patient with cryptococcal meningitis showing the budding yeast cells of C. neoformans surrounded by a characteristic wide gelatinous capsule. The yeasts also show narrow-base budding and characteristic variation in size.
The space occupied by the capsule shows as a clear space between the gray background of the ink particles and the refractile edge of the cell.
India ink/nigrosin stain is a negative, acid stain. This means that the dye easily gives up a hydrogen ion (proton) and the chromophore of the dye becomes negatively charged. Since the surface of most organims cells is negatively charged, the cell surface repels the dye.

India ink stain, previously known as the Nigrosin stain, is a quick, low-resource method. It is widely used for the microscopic detection of cryptococci in CSF. Its a negative stain used to determine the organism’s cellular morphology.
In the India ink preparation, stain fills the background and the thick polysaccharide capsule does not take up the stain, resulting in an appearance of a refractile large white circle against a dark background, giving the appearance of a halo of light

Many times when susceptibility testing is done for P. aeroginosa, a scenario similar to shown in the picture is encountered.
We see that TZP has produced a D shape on the IPM side. This might look very similar to the phenomenon seen in gram positive ICR strains. So what is it?

Published data says that this result is most likely due to
inducible expression of the P. aeruginosa AmpC beta-lactamase.

#MicroRounds (Day 733): Hypothetical case: a parent hears their child use the toilet but not flush (typical behavior!).
But upon entering the bathroom they're horrified to see this worm in the bowl with their kid's poop! How freaked out should they be?? #ASMClinMicro #IDTwitter

Cont.: Here's some additional information (from your friendly neighborhood parasitology lab).
1) Yes, it's actually a worm.
2) You zoom in close and see this on one of the ends of the worm...

Thoughts on upcoming #COVID19 #serology tests:
This is actually quite a challenge! (#Diagnostics often involve a lot of complexities). There is a lot of pressure to roll these tests out, but they need to perform well, or we do more harm than good. #MicroRounds (A thread)

WHY we need these soon:
1. Contact tracing.
2. Can be used to test if a vaccine is working during a clinical trial (70 of them ongoing right now, I believe)
3. Inform public policy makers about rate of asymptomatic cases + previous infections/exposures =informed decision making

1/ Yday on micro rounds we discussed Group A streptococcus (GAS). We briefly touched on the rationale behind using adjunctive clindamycin for severe forms of invasive GAS. So here is a short tweetorial on the topic. @CarlosdelRio7 @Dr_AmyKacin @colleenkraftmd
2/ GAS is an aerobic GPC. GAS invasive disease (iGAS) is defined by isolation of GAS from a normally sterile body site. The most severe of these invasive disease entities are generally thought to be necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS).
3/ Currently, the addition of clindamycin therapy to B-lactams and surgical debridement is recommended by the IDSA for Necrotizing fasciitis and used routinely in management of STSS, despite low rates of PCN resistance . What is the rationale?
