This is a case report of disseminated Penicillium marneffei infection in a patient with leprosy, responding to antifungal therapy. Radiologically there were nodules in the left lung, right pleural effusion, lymphadenopathy in neck, mediastinum and upper abdomen and abscesses in the liver and right parietal lobe. This case highlights a rare infection in a non-HIV related immunocompromised patient, and its nonspecific radiologic manifestations.
Penicillium marneffei, a dimorphic fungus is a rare opportunistic pathogen. It is known to cause infection in immunocompromised patients and recently its occurrence in AIDS patients has been well-documented. Disease with Penicillium marneffei is even rarer among previously healthy individuals. The disease is endemic in Southeast Asia and China. Recognition of this rare disease is important because it is amenable to treatment. We report a case of P. marneffei infection in a previously healthy individual.
Bioconversion of higher strength of domestic wastewater biosolids (sludge) (4% w/w of TSS) by mixed fungal culture of Aspergillus niger and Penicillium corylophilum was studied in a laboratory. The effect of potential mixed fungi on domestic wastewater sludge accelerated the liquid state bioconversion (LSB) process. The highest production of dry sludge cake (biosolids) was enriched with fungal biomass to about 85.66 g/kg containing 25.23 g/kg of protein after 8 days of treatment. The results presented in this study revealed that the reduction of chemical oxygen demand (COD), total suspended solid (TSS), and specific resistance to filtration (SRF) of treated sludge were highly influenced by the fungal culture as compared to control (uninnoculated). The maximum removal rates in treated sludge (biosolids) supernatant recorded were 92% of COD and 98.8% of TSS. Lower SRF (1.08 x 10(12) m/kg) was perceived in microbially treated sludge after 6 days of fermentation. The observed parameters were highly influenced after 8 days of treatment. The influence of pH was also studied and presented in the paper.
The present work aimed to determine the prevalence of aflatoxigenic Aspergillus section Flavi on different types of dairy goat's feed samples obtained from four dairy goat's farms around the central region of Peninsular Malaysia, and to examine the effects of climatic conditions (temperature, relative humidity) of the dairy goat's farms, and their feeding and storage practices on the fungal prevalence of different types of dairy goat's feed. A total of 60 goat's feed samples were obtained, and their proximate composition and water activity were determined, following which they were cultivated on DRBC and AFPA for total fungal load and Aspergillus section Flavi load determination, respectively. Fungal isolates were identified morphologically, and toxigenicity potentials of Aspergillus section Flavi isolates were determined using CCA. The temperature and relative humidity data of all farms were obtained from the Malaysian Meteorological Department. The total fungal loads (on DRBC) of the goat's feed samples were log 0.767 to 7.071 CFU/g which included the common feed contaminants such as Aspergillus, Fusarium, and Penicillium. The Aspergillus section Flavi loads (on AFPA) were log 0.667 to 3.206 CFU/g. Farm A yielded the highest number of Aspergillus section Flavi isolates as well as the highest number of aflatoxigenic isolates. It was found that climatic conditions and different practices between farms positively influenced the fungal prevalence on goat's feed samples based on the Pearson correlation analysis. The prevalence of mycotoxigenic isolates on goat's feed warrants for urgent intervention to ensure that goats are being fed with nutritionally adequate and safe feed. The presence of aflatoxigenic Aspergillus section Flavi isolates indicates the risk of aflatoxin B1 contamination on the goat's feed, aflatoxicosis development in the goats, and aflatoxin M1 bio-transformation in the goat's milk. This is a potential threat to the flourishing goat's milk industry in Malaysia.
We reviewed current literature on four different skin and subcutaneous infections which are often touted as 'emerging diseases' of south-east Asia, namely melioidosis, penicilliosis, sporotrichosis and Mycobacterium marinum infection. Lack of consensus treatment guidelines, high treatment costs and limited investigative capability in certain endemic areas are among the challenges faced by managing physicians. With the increase in borderless travelling, it is hoped that this review will facilitate better understanding and heighten the clinical suspicion of such infections for clinicians in other parts of the world.
Penicilliosis is a rare occurrence among non human immunodeficiency virus (HIV) infected patients. We report here two cases of Penicillium marneffei infection in patients with systemic lupus erythematosus (SLE). Both patients had a recent flare of lupus and were on immunosuppressive drugs when they presented with prolonged fever without an obvious foci of infection, unresponsive to broad-spectrum antibiotics. They were leucopaenic upon admission, with rapid deterioration during the course of the illness. Diagnosis of penicilliosis via fungal isolation from blood culture was delayed resulting in the late initiation of antifungal agents. While both patients ultimately recovered, the delay in diagnosis led to a prolonged hospital stay with increased morbidity. Clinicians should be aware of this uncommon but emerging fungal pathogen in SLE patients and maintain a high index of suspicion in diagnosing this potentially fatal but treatable disease.
Penicilliosis is a systemic fungal infection caused by Penicillium marneffei. The infection is most commonly seen in Southeast Asia, Southern China, Hong Kong, and Taiwan. It is rarely seen among individuals of African descent. Here, we report a case of penicilliosis in an African man from Namibia who was studying in Malaysia. He presented with multiple umbilicated papules associated with cough, fever, loss of appetite, and weight. He also had urethral discharge and admitted to unprotected sexual intercourse with multiple partners. Histopathological examination of a skin papule showed the presence of multiple 2 to 4 microm intracellular yeast cells. Culture of the papule revealed Penicillium marneffei. The serology for human immunodeficiency virus (HIV) was positive. This case illustrates the need to recognize penicilliosis in any individuals staying or travelling to Southeast Asia and the need to look for underlying HIV infection in adults with umbilicated papules.
