Autosomal recessive deficiency in the caspase recruitment domain containing protein 9 (CARD9) results in susceptibility to fungal infections. In the last decade, infections associated with CARD9 deficiency are more reported due to the advent of genome sequencing. The aim of this study was to evaluate the frequency, geographic distribution and nature of mutations in patients with CARD9 deficiency.

Methods: The microbial flora of gut and surrounding environmental of a laboratory strain of Phlebotomus papatasi, the main vector of Zoonotic Cutaneous Leishmaniasis (ZCL) in the old world, was investigated. Biochemical reactions and 16s rDNA sequencing of the isolated bacteria against 24 sugars and amino acids were used for bacteria species identification.
Nocardia cerebral abscesses are rare intracranial lesions. They account for only 1% to 2% of all brain abscesses. They are important in immunocompromised patients, but rarely occur in immunocompetent hosts.

These lesions consisted of singular, well-defined verrucous plaques which gradually developed and disseminated over time. The dermatosis was followed by the development of necrotic swollen lesions localized on the hard palate.

The most common fungal infections in these patients are caused by Aspergillus species.
Case Presentation: Here, we describe Aspergillus osteomyelitis of the ribs and hepatic abscess in a 5-year-old boy.
A 24-year-old man presented with papulopustular, rosacea-like centro- facial lesions. Many Demodex mites were found in the affected area by microscopy of smears from pustules. This observation provides further evidence that demodicosis is a condition distinct from common rosacea.
