Lääkäriä tai muita asiasta tietäviä paikalla? bakteerista kyse

Citrobacter freundii. Ainakin mulla antaa sellaisia tuloksia googlella etta nayttaisi olevan melko normaali loydos ihmisen suolistossa, ei yleensa aiheuta sairastumisia (jos on siis vain siella suolistossa).

en mitään kovin informatiivista löytänyt infektioista mutta etsi itse paremmalla onnella



Hiv-potilailla se on aiheuttanut ripulia ja tässä on yks artikkeli mikä antais ymmärtää että se voi aiheuttaa harmia päästessään muualle elimistöön mut sairastuneilla potilailla on yleensä jotain muuta sairautta jo ennestään. ei tässä nyt niin sanota mutta saan sen käsityksen että tää vois olla semmonen opportunistipöpö joka aiheuttaa ongelmia niillä joilla immuniteetti on heikentynyt jostain syystä

In this investigation, we sought to investigate the characteristics of Citrobacter spp. infections. A retrospective cohort study in a 700-bed, tertiary care, university hospital was carried out during the period from June 1994 to January 2006. Seventy-eight patients (70 adults) with Citrobacter spp. isolates were identified. C. freundii was more common (71.8%), followed by C. koseri (23.1%) and C. braakii (3.8%). The most common associated clinical syndromes were urinary tract infections (52.6% of cases, including eight cases of asymptomatic bacteriuria), as well as intra-abdominal (14.1%), surgical site (7.7%), skin and soft tissue (6.4%), and respiratory tract infections (6.4%). In 29.5% of patients, Citrobacter spp. isolates were associated to polymicrobial infections, principally at sites other than the urinary tract. Antibiograms of 38 consecutive Citrobacter spp. isolates (29 C. freundii) were available. Most active agents were colistin (100%), fosfomycin (100%), imipenem (97.4%), gentamicin (89.5%), nitrofurantoin (89.5%), ciprofloxacin (80.6%), and cefepime (73.7%). Most patients (82.1%) had at least one underlying illness. Combination antimicrobial therapy was administered in 28.2% of cases. One patient died during hospitalization. The length of hospital stay was longer in patients with polymicrobial compared to monomicrobial infections (23 versus 13 days, respectively, p = 0.02). The isolation of Citrobacter species, although rather infrequent, was clinically relevant in the great majority of cases. Further attention should be paid to these pathogens.

ehkä se lääkäri on vain liian innokas? suolistossa on normaalistikin monenlaisia bakteereja ja siellä kuuluu olla kaikenlaista bakteeria.

vai syötkö antibioottia?

tän bakteerin aiheuttamat infektiot on usein sairaalahoidon aikana saatu, ennestään sairaita potilaita siis.



Mut ei tässäkään ole mitään siitä että niitä olisi haettu suolistosta vaan nämä on ollut virtsateissä, hengitysteissä, märkivässä kudoksessa, ja normaalisti steriileissä ruumiinnesteissä

OBJECTIVES: This prospective study was carried out to look for the frequency of isolation of Citrobacter species from clinical specimens and study their antimicrobial susceptibility pattern. METHODS: Patients from whom Citrobacter species were isolated during routine diagnostic testing from January to December 2004 were included in the study. Isolates were identified by standard biochemical tests. Antimicrobial susceptibility testing was performed by disk diffusion method as per National Committee of Clinical Laboratory Standards (NCCLS) guidelines. RESULTS: Citrobacter species were isolated from a total of 205 patients. Infection was nosocomially acquired in 94.6% patients. One hundred eighty one (88.3%) patients had significant underlying illnesses. Culture yielded Citrobacter koseri in 185 (90.2%) and Citrobacter freundii in 20 (9.8%) patients. The distribution of isolates was as follows: urine (46.2%), respiratory tract (16.3%), blood (15.8%), pus (12.1%) and sterile body fluids (9.3%). Drug resistance was observed to be more in C. koseri as compared to C. freundii. CONCLUSIONS: Citrobacter infections are often nosocomially acquired, seen in patients with significant underlying diseases and isolates are commonly drug-resistant. Adoption of hospital infection control practices and a good antibiotic policy may prevent their spread.
