<em>Leptotrichia species </em>(LS) is an anaerobic Gram negative bacillus in the <em>Bacteroidaceae</em> family and part of the normal human oral flora. It is rarely pathogenic, but occasionally causes diseases in immunocompromised hosts. I am reporting a case of cavitary pneumonia caused by LS in an immunocompetent host.

Immunocompromised Hosts

Sphingomonas paucimobilis, a yellow-pigmented, aerobic, glucose non-fermenting, Gram-negative bacillus, is a rare cause of human infection normally associated with immunocompromised hosts. We report a case of bacteraemia and septic arthritis in a 47-year-old diabetic man who presented with septic pulmonary emboli due to S. paucimobilis. The patient had an initial presentation of fever, right knee pain, coughing, dyspnoea and chest pain. The infection was treated successfully by surgical debridement combined with meropenem plus ciprofloxacin, based on the patient's antibiotic susceptibility profile. To our knowledge, this is the first case report for septic pulmonary emboli having arisen from an S. paucimobilis infection.

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.

New Onset

Nocardia is a genus of aerobic, non-motile and non-spore-forming filamentous branching bacteria with fragmentation into bacillary or coccoid forms. Infections caused by Nocardia often occur in immunocompromised hosts and are potentially life-threatening. Nocardia beijingensis has rarely been reported to cause infection in immunocompetent hosts. We present a case of disseminated infection due to Nocardia beijingensis in a patient with no known medical comorbidities, who presented with new-onset seizure. Another interesting finding in our case is that our patient did not have any pulmonary symptoms despite chest CT showing the pulmonary system as the likely primary site of infection. As per our literature review, this is the seventh reported case of infection due to Nocardia beijingensis in an immunocompetent host.

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.
