Nocardia infection following anterior cruciate ligament (ACL) allograft reconstruction is a rare occurrence. We report a case of Nocardia infection of an allograft ACL reconstruction and septic arthritis of the knee joint due to an organism most similar to the novel Nocardia species Nocardia aobensis.

a b s t r a c t a few case reports of coinfections with nocardia and mycobacterium tuberculosis (tb) have previously been published in the literature. we report on a case of concomitant pulmonary nocardiosis and tuberculosis, in a recently diagnosed 55-year-old woman, with rheumatoid arthritis, who had been taking a short course of a low dose corticosteroid. the patient was treated with a combi...

INTRODUCTION Nocardia spp. are common soil-inhabiting bacteria that frequently infect humans through traumatic injuries or inhalation routes and cause infections, such as actinomycetoma and nocardiosis, respectively. Nocardia brasiliensis is the main aetiological agent of actinomycetoma in various countries. Many bacterial non-coding RNAs are regulators of genes associated with virulence factor...

INTRODUCTION Infections remain a major cause of morbidity and mortality in immunocompromised patients and require early diagnosis and treatment. However, correct diagnosis and treatment are often delayed by a multitude of factors. We report what we believe to be the first case of a combined disseminated infection with Nocardia and Mucor in a patient with systemic lupus erythematosus. CASE PRE...

RATIONALE Nocardia species is known as conditional pathogenic bacteria. Disseminated infection caused by Nocardia species is rare and occurs primarily in immunosuppressed patients. Signs and symptoms of this infection are frequently nonspecific making early diagnosis and treatment difficult. PATIENT CONCERNS We report a case of subcutaneous and pulmonary nocardiosis due to Nocardia farcinica ...

Microbiological methods such as Gram staining and culture of low respiratory tract secretions are necessary to detect the real bacterial pathogens that cause lower respiratory tract infections (LRTI). In many cases, Gram stain analysis may be unreliable to determine the cause of LRTI, and bacterial cultures provide adequate information. However, we herein report two cases of lower respiratory t...

BACKGROUND Immunosuppression in Human Immunodeficiency Virus can predispose to opportunistic infections of the central nervous system and can be life threatening without early recognition and management. This can be delayed in undiagnosed Human Immunodeficiency Virus. The present article is the only case report in the literature to describe a first presentation of Acquired Immune Deficiency Syn...

Nocardia are ubiquitous environmental saprophytes that cause pneumonia and disseminated disease in immunocompromised patients. They can also cause localized cutaneous and soft tissue infections in healthy people after direct percutaneous inoculation. Nocardia arthritis is rare in both forms of the disease. Here we present the first published case of a child with septic arthritis caused by N bra...

A soil isolate, strain F829T, which had provisionally been assigned to the genus Nocardia, was subjected to a polyphasic taxonomic study. An almost complete 16S rDNA sequence was determined for this strain; the sequence was aligned with available sequences for nocardiae and phylogenetic trees were inferred using three tree-making algorithms. The organism showed a combination of phenotypic prope...

identification  of clinically  significant  nocardia  species  is essential  for the definitive diagnosis, predict antimicrobial susceptibility, epidemiological purposes,  and  for  an  effective  treatment.   conventional   identification   of nocardia species in routine medical laboratories which is based on phenotypic (cellular morphology, colonial characteristics), biochemical and enzymatic...
