Résumé :
ABSTRACT The aim of this study was to investigate the species of conidial fungi associated with leaf litter of Cedrela odorata (Meliaceae), an endangered red cedar species typical of Amazonian terra-firme forests. Conidial fungi were sampled around C. odorata individuals in three forest areas in the municipality of Belém (Pará State, Brazil). A total of 104 species were identified, with 53 new records for the state of Pará, 46 first records for the Brazilian Amazon, including new records for Brazil (Cordana abramovii), for South America (Acarocybiopsis cubitaensis, Xylocladium claviforme) and for the Americas (Dactylaria biguttulata). A review of species of conidial fungi reported on C. odorata is provided, indicating its distribution in Brazil. For each new record in Brazil, South America and the Americas we present a description, illustrations, geographical distribution and taxonomic comments.

Résumé :
Endemic fungi are thermally dimorphic fungi that have a limited geographic range and can cause both primary disease and opportunistic infections. The Americas are home to more genera of endemic fungi than anywhere else on earth. These include Coccidioides, Histoplasma, Blastomyces, Paracoccidioides, and Sporothrix. Endemic fungi are found across the Americas and the Caribbean, from Blastomyces gilchristi, which extends into the northeast corners of North America, to Histoplasma capsulatum, which occurs all the way down in the southern regions of South America and into the Caribbean Islands. Symptoms of endemic fungal infection, when present, mimic those of many other diseases and are often diagnosed only after initial treatment for a bacterial or viral disease has failed. Endemic fungi place a significant medical burden on the populations they affect, especially in immunocompromised individuals and in resource-limited settings. This review summarizes the ecology, geographical range, epidemiology, and disease forms of the endemic fungi found in the Americas. An emphasis is placed on new and proposed taxonomic changes, including the assignment of new species names in Histoplasma, Blastomyces, and Paracoccidioides.

Résumé :
Both palm weevils, the South American (Rhynchophorus palmarum) (SAPW) and the red palm weevil (R. ferrugineus, RPW), are present in South America, affecting commercial, ornamental, and native palms. These pests oviposit and thrive on selected Arecaceae. R. palmarum mainly infests coconut (Cocos nucifera), oil palms (Elaeis guineensis), and other ornamental and native palms in America, causing a significant social impact on growers. The weevils fulfill a significant ectosymbiotic macro- and microorganism role in the first period of larval development, worsening the damage which, during this period, is not yet apparent. Palm protection in the Brazilian context suggests the use of indigenous agents for microbiological biocontrol. This research identifies three Brazilian Beauveria bassiana isolates: CVAD01, CVAD02, and CVAD06. The results suggest that the strain’s impact on R. palmarum can also be compared with that of the commercial strain Beauveria bassiana. Phylogenetic analysis allowed the delimitation of species of Beauveria (Hypocreales). Pathogenicity tests caused significant mortality in R. palmarum. The isolates CVAD01, CVAD02, and CVADO6 showed high pathogenicity between 7 and 21 days, with mortality rates between 90 and 100%, suggesting that they may be effective biological control agents of R. palmarum in the field when used, within available means, to mitigate the impact of R. palmarum and R. ferrugineus in South America.

Résumé :
The health of the forestlands of the world is impacted by a number of insect pests and some of them cause significant damage with serious economic and environmental implications. Whether it is damage of the North American cypress aphid in South America and Africa, or the destruction of maple trees in North America by the Asian long horned beetle, invasive forest pests are a major problem in many parts of the world. Several studies explored microbial control opportunities of invasive forest pests with entomopathogenic bacteria, fungi, and viruses, and some are successfully utilized as a part of integrated forest pest management programs around the world. This manuscript discusses some invasive pests and the status of their microbial control around the world with entomopathogenic fungi.

Résumé :
Histoplasma is a thermally dimorphic fungus with endemic and opportunistic behavior, which causes a systemic disease known as histoplasmosis. The habitat for this fungus is soil laden with bird and bat droppings, in caves and henhouses, and it persists in the environment long after the contamination. This fungus is widely disseminated in the American continent. In South American countries, the disease is mainly present in Venezuela, Colombia, Peru, Brazil, Argentina, and Uruguay. Man is contaminated by inhaling conidia present in nature, and most infections are mild and subclinical. After being inhaled, conidia undergo phagocytosis by macrophages and mononuclear cells, which are unable to destroy them. They multiply inside these cells, traveling through mediastinal and hilar lymph nodes and into the bloodstream, spleen, bone marrow, liver, skin, and subcutaneous tissue. The diagnosis is based on the detection of the fungus in secretions or tissues and in serology tests. Among these tests, enzyme-linked immunosorbent assays are more sensitive and specific than complement fixation. Tissue biopsies show epithelioid granulomas, with or without necrosis, and fungi within phagocytic cells. Gomori-Groccot staining is required for the visualization of the fungus. A 22-year-old female patient, an undergraduate psychology student, from the urban area of the inner state of Sergipe, no comorbidities, vegetarian, visited a mastologist due to the recent appearance of a nodule in the right breast associated with signs of inflammation and no fever. The clinical examination showed a 2 cm palpable, retroareolar thickening, and thickening of the areolar skin with discrete hyperemia, and no palpable axillary lymph nodes. The patient was initially treated with amoxicillin and clavulanic acid for 7 days. After treatment, there was regression of the inflammation signs upon physical examination; however, the thickening remained and the areolar skin was still thickened and hard. An ultrasound of the right breast showed a well-defined heterogeneous, superficial, and elongated retroareolar nodular image, measuring 3.4×1.2 cm. A breast ultrasound-guided fine-needle aspiration (FNA) was performed, and the cytology test suggested an inflammatory process. After 1 month, the patient returned with two areolar fistulas with yellowish discharge. A new cycle of antimicrobial therapy was started with clindamycin for 14 days. The secretion was decreased over the antibiotic period; however, 14 days after the treatment, the two areolar fistulas were still present with yellowish discharge. A third cycle of antibiotic therapy with metronidazole was administered with no improvement. An excisional biopsy was performed of the area around the fistula and the underlying breast tissue. Two specimens were examined — one skin specimen with the fistulizing areas measuring 1.9×0.8×0.8 cm, and the other specimen measuring 1.7 cm, corresponding to the breast tissue beyond the fistulas, measuring 1.7×1×0.2 cm. Histopathological evaluation of the specimen showed a chronic, granulomatous inflammatory process, with exudative foci and formation of a fistulous tract, chronic inflammatory lymphoplasmacytic reaction, fibrosis, and giant cell reaction. Screening for fungi (Groccot) showed small, clustered yeast-like structures in the cytoplasm of macrophages, suggestive of histoplasmosis. The patient’s clinical tests included hemoglobin of 9 and a white blood cell count of 3,500, with a normal differential count. Screenings for HIV, hepatitis B, and hepatitis C were negative, fasting blood glucose was normal, and liver function was normal. The anemia investigation revealed only a ferroprivic component because of the vegetarian diet. The patient was subjected to general chest and abdominal examinations with no abnormalities. The patient was started on itraconazole 200 mg a day for 1 year, with no relapse until the end of the treatment.
