Résumé

Legionella pneumophila is one of the important pathogen responsible for community –acquired pneumonia attributing for 1-5% of cases. Since early and accurate therapy reduces mortality, rapid and reliable diagnostic methods are needed. A total of 134 samples of blood, urine and respiratory tract fluids were collected. Blood was tested for IgG, IgM and IgA antibodies using commercially available kits. A total of 8 (6%) samples were found to be positive for L. pneumophila by quantitative reverse transcription polymerase chain reaction (qRT‑PCR), compared to conventional PCR where 6 (4.4%) samples were positive. Serology was positive in a total of 32 (23%) cases though only 3 (2.2%) of the PCR‑positive cases were positive by serology as well. These results suggest that real‑time PCR can detect Legionella infection early in the course of the disease before serological response develops.

Résumé

Enteric fever due to Salmonella Paratyphi A (SPA) is a global problem occurring as outbreaks at times. An unusual SPA (2,12:a:‑) variety durazzo has been reported rarely. We report an outbreak of enteric fever due to this variety affecting 43 individuals. The blood samples grew unusual mucoid, lactose non‑fermenting colonies with atypical biochemical reactions in sugar fermentation and amino acid decarboxylation. Isolates had sensitivity to ceftriaxone, chloramphenical, cotrimoxazole, intermediate susceptibility to ciprofloxacin and resistance to ampicillin and nalidixic acid. Identification was confirmed as SPA (2,12:a:‑) at the National Salmonella Centre.

Résumé

Oculomycosis is a major cause of visual impairment. Eye pain, redness, discharge, diminution and photophobia are presenting features. We collected corneal scraping, vitreous, aqueous fluids and conjunctival swabs after the slit‑lamp examination. Ophthalmological findings were hypopyon, stromal congestion, conjunctival congestion and epithelial defect. Direct microscopy of 10% potassium hydroxide (KOH) wet mounts, gram staining, fungal and bacterial cultures were performed. Fungal isolates were obtained in 24% patients with equal number of both sexes and average age 49 years. KOH revealed fungi in 73% samples and 43.33% were positive on Gram staining. Fusarium spp. (36.66%), Aspergillus spp. (23.33%) and melanised fungi (20%) were common etiological agents. Fusarium spp. was more often associated with complications. Trauma was a predisposing factor in 65% cases and occurred mainly with vegetable matter. The majority responded to the conservative management with 5% natamycin and four patients required surgery.

Résumé

Paecilomyces lilacinus is a filamentous fungus found in soil and air, which is a rare cause of ocular infection. The majority of case reports involving P. lilacinus among healthy hosts are of endophthalmitis and keratitis. We report a rare case of keratomycosis by P. lilacinus, in an immunocompetent, which responded well to treatment with ketoconazole. Some species belonging to the genus Paecilomyces such as P. lilacinus generally shows a poor response to conventional antifungal drugs. Therefore, correct identification of clinical isolates to the species level is mandatory for the appropriate treatment of the disease.
