Bacteremic Infection

Flavimonas oryzihabitansis an uncommon organism with distinctive microbiological and biochemical features that is infrequently isolated from humans. The presence of foreign material, including indwelling intravascular catheters and artificial grafts, or various surgical procedures appear to predispose patients with underlying disease to bacteremic infection withFlavimonas. A gram-negative bacillus,F oryzihabitansis sensitive to most antibiotics except first- and second-generation cephalosporins.F oryzihabitansisolated from blood should be considered pathogenic in patients with indwelling catheters or prosthetic materials.Previously designatedPseudomonas oryzihabitansand also known as Centers for Disease Control (CDC) Group Ve-2,F oryzihabitansis an unusual gram-negative, nonfermenting, oxidase-negative bacillus that is uncommonly associated with serious illness in humans.’ First described by Dresel and Stickl in 1928 and initially assigned the nameBacterium typhiflavumbecause of its similarity to the typhoid bacillus, the organism has been isolated from a variety of human sources, including blood, wounds, and abscesses, and (in mixed cultures) from sputum, urine, and cervical cultures.

The Central Nervous System

Salmonella Newport is a Gram-negative bacillus belonging to the Enterobacteria family and the nontyphi Salmonella (NTS), usually related to gastroenteritis. Main difference between NTS and Salmonella typhi is that the last one evolves to an invasive disease easier than NTS. These can progress to bacteremias in around 5% of cases and secondary focuses can appear occasionally, as in meningitis. An infection of the central nervous system is uncommon, considering its incidence in 0.6–8% of the cases; most of them are described in developing countries and mainly in childhood, especially neonates. Bacterial meningitis by NTS mostly affects immunosuppressed people in Europe. Prognosis is adverse, with a 50% mortality rate, mainly due to complications of infection: hydrocephalus, ventriculitis, abscesses, subdural empyema, or stroke. Choice antibiotic treatments are cefotaxime, ceftriaxone, or ceftazidime. The aim of this paper is to present a case of meningitis caused by Salmonella Newport diagnosed in a five-year-old girl living in a rural area of the province of Ourense (Spain), with favorable evolution and without neurological disorders.

Melioidosis is a serious infection caused by the soil-dwelling Gram-negative bacillus Burkholderia pseudomallei. It is most commonly reported in north-east Thailand and northern Australia, but is increasingly recognized around the world. Infection is predominantly acquired through bacterial inoculation, often related to occupation, and mostly affects adults between the fourth and sixth decade who have risk factors such as diabetes mellitus and renal impairment....

Chemotherapy Induced Neutropenia

Melioidosis is a bacterial infection, caused by Gram-negative bacillus, Burkholderia pseudomallei, widespread in Southeast Asia and the northern part of Australia, resulting in a high mortality rate in severe infection. However, it has rarely been reported in patients with chemotherapy-induced neutropenia. The authors described a case of melioidosis in a neutropenic patient presenting with septic shock after receiving chemotherapy. Blood and urine cultures were positive for Burkholderia pseudomallei, and CT scan showed multiple pulmonary nodules and hepatosplenic abscesses. The patient was successfully treated with antibiotics for the infection and with combined modalities for a malignancy.

Intraocular Fluid

This report describes the presence of Stenotrophomonas maltophilia endophthalmitis after phacoemulsification in a 66-year-old woman. The patient presented with ocular redness and pain, as well as hypopyon in the anterior chamber and reduction of visual acuity to hand motion. Intraocular fluid examination revealed a lipopolysaccharide level of >2.5, which suggested bacterial endophthalmitis. The patient was promptly treated with intravitreal ceftazidime 2 mg and vancomycin 1 mg, as well as intravenous infusion of cefuroxime 750 mg, all administered simultaneously at 12-hour intervals. She also received topical levofloxacin eyedrops, once per hour. Subsequently, pathology culture confirmed the presence of the Gram-negative bacillus, S. maltophilia. The presence of lipopolysaccharide in intraocular fluid is an important early indicator of bacterial endophthalmitis, which can provide guidance for clinical treatment.

Icu Treatment

Bacteria are the most frequent causes of severe sepsis and septic shock, while viruses, fungi, and parasites are implicated less often. Positive cultures are found in only 60% of cases; this may be the result of previous antibiotic therapy or inadequate sampling or testing. The etiology of sepsis is constantly changing; whereas Gram-negative organisms used to make up the majority of cases, Gram-positive bacteria now predominate. Sepsis due to fungal disease has also seen a dramatic rise. These changes may be explained by alterations in patient demographics, such as an increasingly elderly population with multiple comorbidities; an increased frequency of indwelling catheters or devices; and greater numbers of patients with immunosuppression as a result of disease or drug therapy. This chapter covers symptoms, demographics, diagnosis, investigation, prognosis, and treatment within the ITU environment.
