For culture they require aerobic conditions, but growth on blood agar may be slow, and incubation for periods longer than 48 h is usually necessary. As cultures enter the stationary phase, nocardiosis en animales filaments tend to fragment into coccobacillary forms.

Nocardia species (Nocardiosis)

Although the organisms are gram positive, many strains give a faint beaded appearance nocardiosis en animales alternating positive and negative areas.

Interpretation of these data may be complicated by several factors.

When data are from a reference laboratory that is likely to receive referral isolates from patients who are intolerant of therapy or for whom therapy has failed, there is a potential for bias in their interpretation.

Based nocardiosis en animales recommendations from Tindall et al. Speciation of isolates suspected of being an nocardiosis en animales actinomycete requires a 16S rRNA gene sequence with a minimum length of bp.

Nocardia species

Limitations to identifying aerobic actinomycetes by molecular methods include: It is recommended to send clinical isolates to a nocardiosis en animales laboratory for confirmation of identification when adequate sequencing technology and analysis are unavailable.

These infections may be localized or disseminated and are more common and nocardiosis en animales more serious in severely immunocompromised and debilitated patients. Cases may go undiagnosed, either because there is a delay in performing necessary diagnostic tests invasive biopsies for seriously ill patients or because the infection partially or successfully responds when prophylactic broad-spectrum antimicrobial therapy is prescribed Pu lmonary Nocardiosis Pulmonary nocardiosis may be associated with nonspecific clinical findings; however, immunocompetent patients may have a chronic course, as opposed to the progressive, disseminated, and life-threatening infection seen in severely immunocompromised patients.

Metastatic infective foci may be present but unrecognized at the time of the patient's initial presentation with pulmonary nocardiosis, and infection in these sites may not become clinically evident until after the patient has begun receiving antimicrobial therapy.

However, very rarely, it may result from a primary nonpulmonary cutaneous infection site In patients with primary pulmonary nocardiosis, the development of disseminated infection may result in brain and nocardiosis en animales lesions and invariably has a significant adverse effect on the patient's prognosis.

As seen with pulmonary nocardiosis en animales, the patients at highest risk for developing disseminated infections are severely immunocompromised patients.

The brain is the most frequent nonpulmonary site involved in disseminated nocardiosis, and cerebral nocardiosis is an important cause of cerebral nocardiosis en animales occupying lesions. However, the infection may also involve multiple other deep organs including the kidney, spleen, liver, and rarely, bone, skin, and joints In the brain and other organs, abscess formation is a nocardiosis en animales common pathologic manifestation of disseminated infection Patients with cerebral nocardiosis may present acutely with signs of sepsis and intracranial mass effects However, severely immunocompromised patients with nocardial cerebral abscess may frequently be asymptomatic initially, and demonstate a prolonged latency up to 3 years before this type of clinical presentation in infected patients following the commencement of immunosuppression Computed tomographic CT scanning is an extremely useful technique for making the diagnosis and may also be used to monitor the patient's response to treatment Specific investigations to nocardiosis en animales cerebral involvement are recommended in all cases of pulmonary and invasive nocardiosis since a brain abscess may be a common serious complication in these patients, and early lesions may be asymptomatic C utaneous Nocardiosis Cutaneous nocardiosis may be subdivided into four clinical types: These infections most commonly affect patients in rural areas in developing countries.

Patients with these chronic infections may give a history of specific minor localized traumatic injury.
