We report a case of pyogranulomatous pneumonia due to infection with Mycobacterium goodii in an adult female spotted hyena (Crocuta crocuta). The lungs of the animal showed consolidated, granulomatous lesions, and they were extensively and severely infiltrated. Polymerase chain reaction sequencing of isolated crude lung tissue DNA, and boiled lung culture samples, all confirmed that the causative organism was M. goodii, a recently described fast-growing organism closely related to the nonpathogenic mycobacterial species M. smegmatis. The current study illustrates that this organism can be pathogenic and cause extensive pulmonary disease.

The aim of the work was to develop a PCR-based assay for detection of L. pneumophila and L. micdadei in environmental samples as well as in clinical samples from low respiratory tract and to assess its analytic characteristics. The assay was used during investigation of the outbreak developed in July 2007 in town Verkhnyaya Pyshma (Sverdlovsk region). Polymerase-chain reaction (PCR)with fluorescent detection,sequencing and cloning of DNA fragments were used. Developed assay based on the PCR with fluorescent real-time/ endpointdetection is able to detect L. pneumophila in clinical and environmental samples and to quantify amount of bacterial DNA in water. Specificity of analysis (100%) was assessed using the panel of bacterial strains and samples from healthy individuals. Analytic sensitivity of assay and quantitation limit was 1000 GU in 1 ml. Sensitivity of the assay of artificially contaminated biological samples was 1000 bacteria in 1 ml. During outbreak investigation L. pneumophila DNAwas detected in 4 lung samples from 4 fatal cases, from 1 of 2 sputum samples, 1 of 2 bronchoalveolar lavage samples with X-ray confirmed pneumonia. Legionella's DNA was found in samples from cooling towers, central hot water supply as well as from showerheads in apartments of 3 patients. Fountain and drinking water samples were PCR-negative. Specificity of PCR-positive results was confirmed by sequencing. Use of the assay during outbreak in- vestigation allowed to confirm the diagnosis in fatal cases and quickly identify the possible source of infection.

We describe a case of systemic lupus erythematosus (SLE) complicated with multifocal leukoencephalopathy (PML). A 57-year old woman, who had a five-year history of SLE, was admitted to our hospital because of fever and multiple subcutaneous nodules. Diagnosis of disseminated cryptococcosis was made based on histological and bacteriological examinations, and she was successfully treated with anti-fungal drugs. Corticoteroids were increased for persistent lupus activities. One month later, however, she gradually developed disorientation and short-term memory loss. A brain magnetic resonance image (MRI) showed a focal lesion in the white matter of the right frontal lobe. Brain biopsy demonstrated demyelinating lesions with the presence of JC viral antigen. Polymerase chain reaction also revealed JC virus DNA in the cerebrospinal fluid. Her condition gradually progressed, and she died a year later due to pneumonia. Although acquired immunodeficiency syndrome is currently the most common disease associated with PML, patients with autoimmune diseases receiving immunosuppressive therapy also have risks for developing PML. In patients with SLE presenting with subacute neurological abnormalities and white matter lesions in the brain, PML should be considered in the differential diagnosis.

Endogenous Aspergillus endophthalmitis (AE) is a rare complication of invasive aspergillosis in transplant patients. In this report, we have described a patient who underwent liver transplantation because of drug-induced cholestatic cirrhosis and developed AE at 2 weeks after the surgery. The patient was a 22-year-old man who received a right liver lobe from his father. The operation was uneventful but the patient developed signs and symptoms of small-for-size syndrome after the second day of surgery. The patient received intense immunosuppression with methylprednisolone for 3 days, tacrolimus and mycophenolate mofetil from the first day after the operation, with ceftriaxone and metronidazole as prophylactic antibiotics. Because of signs of respiratory distress with pneumonia, vancomycin and amphotericin B were added empirically to his regimen. Polymerase chain reaction for aspergillus DNA in the blood was positive. The patient received one course of methylprednisolone pulse therapy for signs of acute rejection at day 10, and tacrolimus was changed to sirolimus because of a rising serum creatinine and convulsions. After 2 weeks, the patient's symptoms improved and liver function tests were normal, but the complained of sudden intense pain in the left eye with unilateral blurred vision, redness, and other signs of endophthalmitis upon examination by an ophthalmologists. After 24 hours, visual acuity decreased to light perception. AE was confirmed by microscopy and culture of the vitreous fluid and retinal biopsy. Despite changing amphotericin to intravitreal injection of voriconazole followed by intravenous voriconazole and transient resolution of the symptoms, no improvement was seen in visual acuity. Pain and signs of inflammation in the eye recurred after 2 weeks. At last the patient underwent enucleation for resistant infection and fear of involvement of the other eye by aspergillosis or sympathetic ophthalmia.

This study aimed to investigate the occurrence of respiratory syncytial virus (RSV) infections in camels in Sudan. A total of 272 camel lung specimens showing pneumonia were collected from slaughter houses at four different areas in Sudan, additionally 8 specimens were collected from outbreaks of respiratory infection in camels. Using sandwich ELISA kits for RSV antigen detection 4 out of 280 tested lungs (1.4%) were positive, all were from Central Sudan (Tambool slaughter house). FAT was used to confirm the ELISA positives. Polymerase chain reaction RT/PCR was applied for the detection of RSV genome in camel lungs; 1 out of 4 ELISA positives was positive by RT/PCR. Using indirect ELISA kits 135 out of 495 (27.3%) camel sera showed antibodies to RSV, highest prevalence was observed in Western (33.5%) then Central (31.6%) and Eastern Sudan (23.5%). Based on the manufacturer specified calculations for OD readings, most of positive sera (90/135) were low reactive (1+). This is the first report for the detection of RSV antigen, genome and antibody in camels in Sudan.

Cytomegalovirus (CMV) can be classified into 4 subgroups based on genotype variation of the glycoprotein B (gB) encoded by UL55 gene. Little is known about the CMV gB genotype distribution and its clinical implication in patients who receive hematopoietic stem cell transplant (HSCT) in China. In this study, which comprises 101 HSCT patients with CMV infection, we have found that 36 patients (35.64%) were infected with CMV genotype gB1, 3 patients (2.97%) with gB2, 39 patients (38.61%) with gB3, 1 patient (0.99%) with gB4, and 17 patients (16.83%) were infected with mixed CMV genotypes. We also found that CMV gB3 was associated with a high risk of CMV pneumonitis; nevertheless, there were no significant differences among patients with gB genotypes with respect to the other CMV diseases; no significant differences between patients with gB genotypes with respect to type II-IV acute graft-verses-host disease (aGVHD) and chronic GVHD (cGVHD) was found either. Interestingly, 5 patients (4.95%) were infected with a CMV variant that lacked a signature RsaI digestion site determined by Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), subsequent cloning and sequencing identified this CMV RsaI minus variant to be novel, herein designated as gB5. Overall, these findings suggest that CMV gB1 and gB3 are prevalent among HSCT recipients with CMV infections, and gB3 CMV infection is a risky indicator for CMV pneumonitis; furthermore, a novel CMV variant in a subset of Chinese HSCT recipients is identified and designated as gB5.

Rapid, accurate diagnosis of community-acquired pneumonia (CAP) due to Mycoplasma pneumoniae is compromised by low sensitivity of culture and serology. Polymerase chain reaction (PCR) has emerged as a sensitive method to detect M. pneumoniae DNA in clinical specimens. However, conventional real-time PCR is not cost-effective for routine or outpatient implementation. Here, we evaluate a novel microfluidic real-time PCR platform (Advanced Liquid Logic, Research Triangle Park, NC) that is rapid, portable, and fully automated. We enrolled patients with CAP and extracted DNA from nasopharyngeal wash (NPW) specimens using a biotinylated capture probe and streptavidin-coupled magnetic beads. Each extract was tested for M. pneumoniae-specific DNA by real-time PCR on both conventional and microfluidic platforms using Taqman probe and primers. Three of 59 (5.0%) NPWs were positive, and agreement between the methods was 98%. The microfluidic platform was equally sensitive but 3 times faster and offers an inexpensive and convenient diagnostic test for microbial DNA.

A 4-6-mo-old female red fox (Vulpes vulpes) was presented to the Atlantic Veterinary College (AVC) Teaching Hospital, Prince Edward Island, Canada. On presentation, the fox was weak and had pale mucous membranes. A complete blood count and a serum biochemistry profile were performed. Blood smear examination revealed low numbers of erythrocytes containing centrally to paracentrally located, single, rarely multiple, approximately 1 x 2 microm, oval to round organisms with morphology similar to Babesia microti. Polymerase chain reaction testing and DNA sequencing of the Babesia species 18S rRNA gene were performed on DNA extracted from whole blood. Results were positive for a Babesia microti-like parasite genetically identical to Babesia (Theileria) annae. The fox was euthanized due to poor prognosis for recovery. Necropsy examination revealed multifocal to locally extensive subacute nonsuppurative meningoencephalitis, an eosinophilic broncho-pneumonia, a moderate diffuse vacuolar hepatopathy, and lesions associated with blunt trauma to the left abdominal region. This is the first reported case of a red fox in Canada infected with a piroplasm. It remains uncertain whether the presence of this hemoparasite in this fox was pathogenic or an incidental finding. The potential for competent vectors of Babesia species on Prince Edward Island, the potential for this Babesia microti-like parasite to infect other wild and domestic canids, and the significance of this parasite to the health of infected individuals are yet to be determined.

Herpes simplex encephalitis (HSE) is a rare complication of neurosurgical procedures but must be considered in early deterioration of the postoperative patient. This is the first report of HSE following spinal cord tumor resection. A 65-year-old woman had C2-C5 laminectomy for subtotal resection of intramedullary ependymoma. Six days postoperatively she developed fever, vomiting and rapid decline in mental status. Brain MRI revealed enhancement of left insular cortex. Polymerase chain reaction on cerebrospinal fluid (CSF) identified herpes simplex virus type 1 (HSV-1) as the causal agent. Twenty-one days of acyclovir led to improvement. Three subsequent admissions to neurological intensive care unit were required for deterioration in mental status, including pneumonia, hydrocephalus and deep vein thromboses. Ventriculoperitoneal shunt (VPS), tracheotomy, percutaneous intravenous central catheter (PICC) line and percutaneous endoscopic gastrostomy (PEG) were placed. She was discharged to skilled nursing home care. Acyclovir is effective therapy against HSV, though outcomes may be poor even in optimally treated cases. Empiric treatment must be started even in the absence of serologic evidence of HSV infection if suspicion for HSE is high.
