 Penicillium Species
Penicillium marneffei is pathogenic particularly in patients with AIDS and its isolation from blood is considered as an HIV marker in endemic areas.
Penicillium marneffei is a pathogenic fungus and specifically infects patients with AIDS who live at or visit Southeast Asia (Thailand and adjacent countries, Taiwan, and India) where the fungus is endemic [558, 2090, 2176].
Penicillium marneffei is easily induced to produce the arthroconidial yeast-like state by subculturing the organism to an enriched medium like BHI and incubating at 35°C, in which after a week, yeast-like structures dividing by fission and hyphae with arthroconidia are formed [525, 1280, 2120, 2178].

Under cold storage conditions, blue mold lesions (from wound infections) caused by the common species may be expected to be one to one and a quarter inches in diameter eight to ten weeks after infection.
In rots caused by other Penicillium species, the decayed tissues are firmer, may lack surface growth under cold storage conditions, and are slow-growing compared with P.
The Penicillium expansum type of blue mold has been the form most frequently reported, but a number of other less common species, which are also usually less aggressive, have been encountered.

The growth and survival of the psychrotroph Penicillium spinulosum in paperboard was studied along with the wicking characteristics of ultra-pasteurized milk to understand sporadic fungal contamination of ultra-pasteurized, extended shelf life milk products.
Penicillium spinulosum was detected in 84% of samples at 3.2, 72% at 6.4, 50% at 9.5, and 28% at 12.7 mm from the uncoated edge.
Penicillium spinulosum survived in the interior of paperboard for the entire incubation period.

 Nucleotide sequence and the action of ribotoxin gene (sar gene) of Penicillium isolates from Taiwan
Species of Penicillium from collections in Taiwan that carried sar gene and secreted ribotoxic proteins were identified, and the DNA sequences of the genes were determined and compared.
The Penicillium species that carry sar gene, but fail to act in ribosome-inactivation, belong to the subgenus Furcatum and are taxonomically distant from Aspergillus.
Reasons for the carrying of the sar gene in Aspergillus or in Penicillium have been questioned because the sar gene is not a constitutive gene for all species of Aspergillus (Lin et al., 1995) or Penicillium (this study).
