Bacteremia is when there are bacteria present in your bloodstream. Sometimes, bacteremia can have no symptoms and clear on its own. Other times, it can cause a bloodstream infection that can develop into serious complications. Many different bacteria can cause bacteremia.

What is Staphylococcus hominis?

Staphylococcus hominis is a Gram-positive coagulase-negative member of Staphylococci that exists as a commensal on the human body, especially in the areas with apocrine glands, axillae, and the pubic region.

What is the size of a staph hominis?

Both the species of S. hominis are Gram-positive, nonmotile, non-spore-forming cocci with an average size of 1.0–1.5 μm in diameter . The arrangement of the cells is characteristic of all Staphylococci species where the organisms occur singly or form tetrads and smaller numbers of pairs.

How are staphlococci classified?

The species of Staphylococci are classified into different species primarily on the basis of DNA–DNA hybridization. Besides, other characteristics like fatty acids composition and G+C content are also observed. The subspecies of S. hominis are further divided on the basis of their activity against novobiocin and their habitat. S. hominis subsp. hominis consists of strains that are susceptible towards novobiocin and are primarily found on the skin surface, whereas S. hominis subsp. novobiosepticus is resistant to novobiocin and can be isolated from blood.

How long does it take for a staph to colonize?

Strains of S. hominis are known to colonize the skin of a person for relatively short periods of time, usually several weeks to several months, compared to many of the strains of the predominant species Staphylococcus epidermidis that persist for one to several years.

What is the Hominis species?

The term ‘hominis’ is derived from the Latin term ‘hominis’ which means humans, and it thus is named for the host on whose skin this species is commonly found. Like all Staphylococci, S. hominis is also clustering Gram-positive cocci, nonmotile, non-spore-forming, and facultatively anaerobic.

Why is it important to avoid S. hominis?

Because S. hominis is a multi-drug resistant species and is capable of forming elaborate biofilms, it is necessary to employ different resistant strategies to avoid such infections. The following are some preventive strategies that can be followed to avoid such infections:

How big is S. hominis?

Both the species of S. hominis are Gram-positive, nonmotile, non-spore-forming cocci with an average size of 1.0–1.5 μm in diameter.

What is A41.9?

Some of our infectious disease providers, however, like to use the term septicemia which codes to A41.9, Sepsis, unspecified organism. This is somewhat of a conundrum when infectious disease providers use this term when the attending hospitalists are saying “no sepsis and/or just bacteremia” and the patient does not meet our systemwide sepsis ...

Can you code R65.2 for severe sepsis?

Secondly, it gives the coding professionals permission to use the R65.2, Severe sepsis, code without needing the physician to use the term “severe sepsis.”. With septicemia, it may be helpful to educate providers before sending a clinical validation query.

Is bacteremia a DRG?

If bacteremia ends up being the principal diagnos is, it actually groups in the sepsis DRG set anyway. The issue is that the word “septicemia” seems to distinguish symptomatic bacteremia from brushing-teeth asymptomatic bacteremia; the term is a bit antiquated, like using severe sepsis which really isn’t a thing anymore either under the Sepsis-3 definition.

Is bacteremia a symptom code?

If a patient is admitted because of bacteremia, it should be the principal diagnosis even though bacteremia is a symptom code, because it is the condition that occasioned the admission.

Is bacteremia without acute organ dysfunction included in the definition of sepsis 3?

When the Sepsis-3 definition was first introduced, one of the authors confirmed to me that bacteremia without acute organ dysfunction is not included in the definition of Sepsis-3. This caused your dilemma.

Can bacteremia be treated with IV antibiotics?

There will be a positive culture (probably a contaminant) and based on age or comorbid conditions the patient will be treated with IV antibiotics for the appropriate length of time based on the pathogen.

Can you code conditions that are no longer on the differential at discharge?

We cannot code conditions that are no longer on the differential at discharge.

Is there a bacteria in blood?

No. There is no bacteria 'from the patient' that was growing in any blood. This 'sounds' like a sampling error, consequence of improper lab technique with skin contamination by tech or at time of draw? This is not a valid finding.

Is there a code for bacteremia?

Sorry, the condition does not exist...there is no Bacteremia; thus, no code for bacteremia.

Is Bacteremia a lab finding?

Paul I hear you, but the condition did exist. Bacteremia is a lab finding. The bacteria in the blood culture was real.The determination that it was a contaminant is from the type of bacteria found in the bottle.

How is S. hominis differentiated from staphylococci?

hominis can be differentiated from staphylococci by its colony morphology and pigmentation patterns, predominant tetrad cell arrangement, poor growth in thioglycolate, low tolerance of NaCl, and carbohydrate reaction pattern.

Which staph is sensitive to desferrioxamine?

It is one of only two species of Staphylococcus to display sensitivity to desferrioxamine, the other being S. epidermidis. Unlike S. epidermidis, S. hominis produces acid from trehalose, so the two tests together serve to identify the species.

How many S. hominis novobiosepticus cultures are there?

hominis, now called S. hominis subsp. hominis, that in 2010, a MicroScan system that clinical microbiology laboratories used, identified 7 of 31 S. hominis novobiosepticus cultures as S. hominis hominis. The relationship between the two was unknown, but antibiotic-resistant isolates of S. hominis belonged only to SHN.

How big is a S. hominis colony?

Description. Colonies of S. hominis are small, usually 1–2 mm in diameter after 24 hours' incubation at 35 °C, and white or tan in colour. Occasionally, strains are resistant to novobiocin and may be confused with other resistant species (e.g. S. saprophyticus ). It is one of only two species of Staphylococcus to display sensitivity ...

Where do staphylococci live?

Numerous coagulase-negative staphylococci appear commonly on the skin of human. Of these species, S. epidermidis and S. hominis are the most abundant. While S. epidermidis tends to colonize the upper part of the body, S. hominis tends to colonize in areas with numerous apocrine glands, such as axillae and the pubic region. In a certain study, S. hominis was calculated to account for 22% of the total staphylococcal species recovered from individuals, second to S. epidermidis at 46%. S. hominis is the predominant species on the head, axillae, arms, and legs. S. hominis, as well as most other staphylococcal species common on the human skin, is able to produce acid aerobically from glucose, fructose, sucrose, trehalose, and glycerol. Some strains were also able to produce acid from turanose, lactose, galactose, melezitose, mannitol, and mannose. Most strains colonize on the skin for relatively short periods of time compared to other Staphylococcus species. They, on average, stay on the skin for only several weeks or months. The cell wall contains low amounts of teichoic acid and glutamic acid. The cell wall teichoic acid contains glycerol and glucosamine. S. hominis cells are Gram-positive cocci, usually 1.2 to 1.4 μm in diameter. They appear normally in tetrads and sometimes in pairs.

How many strains of s. homini are resistant to lysozyme?

Based on a total of 240 strains, all were resistant to lysozyme, some were slightly resistant to lysostaphin, 77% were susceptible to penicillin G, 97% to streptomycin, 93% to erythromycin, 64% to tetracycline, and 99% to novobiocin. Multi drug resistant strains of s. hominis have been isolated from blood and wound cultures in humans.

What is the optimal NaCl concentration for S. hominis?

Optimal NaCl concentrations of the agar culture for the growth of S. hominis seem to be around 7.5%, and a salt concentration of 15% yielded poor growth to no growth at all.

What is the genome of S. hominis?

The S. hominis genome is 2.25 Mb, with a GC composition of 31.4%, and contains 2131 protein coding genes [7]. There are no proteins unique to S. hominis. The genome of S. hominis consists of multiple antibiotic resistant genomic elements that decrease the organism’s susceptibility to antibiotic treatments. These genes include mecA, which encodes for the resistance of methicillin or oxacillin, and is located on the Staphylococcal Cassette Chromosome mec (SCCmec), a mobile genetic element [2]. In biofilm formation, the gene atl1E is responsible for initial adherence of the S. hominis strain and the gene sea is responsible for toxin production [8]. The S. hominis genome also expresses the ermC gene, a ribosomal target for modification, and the lnuA gene which mediates enzymatic drug inactivation especially in macrolides, lincosamides and streptogramin B antibiotics (MLSB) [9]. Genomic analysis of S. hominis subsp. Hudgins has revealed absence of flagellar encoding genes [12] .

When was S. hominis first classified?

Kloos and Schleifer first classified S. hominis in 1975 (10) .

How does S. hominis produce odor?

S. hominis possesses unique metabolic processes that contribute to human body odor production. As a heterotroph, it hydrolyzes simple monosaccharides and amino acids through mostly aerobic respiration to obtain energy [14]. Interestingly, S. hominis ingests the peptide S-Cys-Gly-3M3SH through secondary active transport as the precursor to the thiolalcohol that is responsible for malodor. The cotransporter called the SH1446 transporter couples the proton movement with oligopeptides [14]. Once inside, peptidases and lyase-catalyzed reactions lead to the production of not only 3-methyl-3-sulfanylhexanol (3M3SH), the odor causing compound, but also pyruvate, glycine, and ammonia [14]. 3M3SH is then presumed to be exported through the bacterial membrane [14]. This process is thought to be nutritionally beneficial to S. hominis, as it releases nitrogen, amino acids, and a carbon source in pyruvate. Targeting the SH1446 cotransporter is now a potential solution for controlling body odor. To test the effect of overexpressing the proton-coupled oligonucleotide membrane transporter (POT), E. coli was transformed with a vector that encoded POT. The resulting E. coli was found to be capable of malodor production [14].

How long does it take for S. hominis to form biofilm?

There are also dangers of nosocomial infection via invasive medical devices; S. hominis biofilm formation peaks between 4-24 hours of weak adherence and decreases in adherence after 48 hours. The gene atl1E for an autolysin responsible for initial adhesion was found in all strains [8].

What are the mechanisms of pathogenesis?

hominis is a common commensal bacteria on human skin, its different mechanisms of pathogenesis are not fully understood. Some pathogenic mechanisms include adhesion and invasion of cells, antimicrobial peptides, extracellular toxins, and biofilm formation.

What is the size of a S. hominis colony?

S. hominis is a Gram-positive spherical, non-motile bacteria with a raised center measuring about 1.0 to 1.5 μm in diameter [10]. Colonies are small and often grow in tetrads with wide beveled edges that develop with age. Older colonies also exhibit concentric rings of light and dark color [10].

What is the antimicrobial peptide that protects against S. aureus?

Studies show that certain strains of S. hominis can provide protection against S. aureus through the production of an antimicrobial peptide (AMP) called hominicin [13], [17]. AMPs are known to control growth of microorganisms residing on the skin’s surface.
