Opis:
Introduction: Fungal paranasal sinusitis can be either invasive or noninvasive. Saprophytic infections, fungus balls (FB) and allergic fungal rhinosinusitis are noninvasive (AFR). Materials and methods: The present study examined 521 patients who underwent endoscopic sinus surgery between January 2016 and April 2017 due to chronic paranasal sinusitis at the Department of Laryngology and Laryngological Oncology of the Upper Silesian Medical Centre in Katowice. The aim of the study was to analyze histopathological and microbiological material collected intraoperatively and to determine incidence and type of fungal infections among patients treated for chronic sinusitis. Results: Chronic fungal sinusitis was confirmed in 10 of 521 operated patients. The study group consisted of 9 females and 1 male. Histopathological examination revealed dead mycelium in 5 patients and colonies of Aspergillus spp. in 4, while microbiological examination revealed Candida albicans infection in 1 case. Allergy to inhalant allergens of fungal spores of Alternaria and Penicillium was confirmed in a 73-year-old patient, which, based on the whole clinical presentation, enabled to diagnose chronic allergic fungal sinusitis. The most common location of mycelium was maxillary sinus, followed by sphenoid sinus. Discussion: The most common form of noninvansive fungal sinusitis is the so-called fungus ball, which was also confirmed in our report (95% of the test subjects). AFRS is more likely to occur in warm, moist climates that favor the growth of fungi.

Opis:
The role of fungi in the treatment of wastewater has been extensively researched. Many genera of fungi have been employed for the dye decolourization either in living or dead form. In this study, the removal of an acidic dye, Indigo Carmine (IC), from an aqueous solution by biosorption on dead fungus, Pleurotus ostreatus, was investigated. The effects of contact time, initial dye concentration, amount of dead biomass, agitation rate and initial pH on dye removal have been determined. Experimental results show that an increase in the amount of dead biomass positively affected the dye removal. The highest removal was obtained at 150–200 rpm. Slightly lower removing activities were found at lower agitation rates. The dye adsorption effi ciency was not affected by pH except minor variation in the pH of 2–8. Color removal was observed to occur rapidly within 60 minutes. The removal of dye by dead biomass of P. ostreatus was clearly dependent on the initial dye concentration of the solution. Dye removal was reduced from 93% to 64% as concentration was increased from 50 to 500 mg/L Indigo Carmine. This study showed that it was possible to remove textile dyes by dead biomass of P. ostreatus.

Opis:
Aspergillus glaucus is a fungus able to tolerate low water activity of the environment. Its dense growth and sporulation were found on basaltic stones with epilithic lichens after 14 years of storage at a temperature of 4–7°C and relative humidity of 14–18%. Dust and soil particles deposited on the lichen thalli and dissolved in the water condensed on the stones during the storage period, apparently served as a nutrient source for the fungus. Probably, strongly xeric water regime on basaltic stones suitable for A. glaucus did not allow mesophilic fungi to develop and prevented the xerotolerant fungus from competition with other microfungi for nutrient sources. It is also possible that specific cellular mechanism associated with the production of chaotropic compounds (such as glycerol) supported germination and development of A. glaucus at low temperatures, which were considered non-optimal for the fungus.

Opis:
The second wave of the COVID-19 pandemic has affected India significantly with country reporting more than 400,000 cases in the month of May 2021 and health system almost collapsing. This was attributed to the new mutant strain also called as the ‘Delta Strain’ which led to high surge of cases across the country. As the country was stabilising over this situation, another imminent threat in the form of Covid Associated Mucormycosis (CAM) challenged the already burdened health system of India. Also called as ‘Black Fungus,’ cases of CAM began to rise rapidly in the last week of May 2021 with multiple states reporting steady rise in the number of cases. Based on the published literature, India contributed to approximately 71% of global cases of CAM from December 2019 to start of April 2021, with majority of the cases occurring during the second wave. The present paper focuses on the epidemic of CAM during the second wave in India highlighting the causes, symptoms and various treatment modalities that have been adopted to cure the disease. Also, spotlight has also been thrown on some other nations where cases of CAM have begun to emerge. Some key recommendations are also mentioned which can prove vital towards disease prevention.

Opis:
The effect of Phlebiopsis gigantea treatment in control of Heterobasidion parviporum in Norway spruce is less effective than that in control of Heterobasidion annosum in pine. It is necessary to apply other fungi, for example, Pleurotus abieticola in Norway spruce stands. Thus, it is necessary to assess the activity of major ligninolytic enzymes, that is, laccase, lignin peroxidase (LiP), manganese peroxidase (MnP) and versatile peroxidase (VP) produced by P. abieticola, which may be effective in the fast degradation of Norway spruce wood. Three strains of P. abieticola (Pa1-3) were grown on pieces of Norway spruce sapwood and heartwood for 50 days in laboratory conditions. Enzymatic activity was determined using spectrophotometry. Pleurotus abieticola produced laccase, LiP, MnP and VP. The activity of laccase was low, ranging 0–3.696 and 0–0.806 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 3.696 mU/μg of protein in sapwood and in Pa3 = 0.806 mU/μg of protein in heartwood was observed after 30 and 50 days of incubation, respectively. The activity of LiP was also low, ranging 0–0.188 and 0–0.271 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 0.271 mU/μg of protein in sapwood and in Pa2 = 0.188 mU/μg of protein in heartwood was observed after 40 and 20 days of incubation, respectively. The activity of MnP ranged 0–17.618 and 0–12.203 mU/μg of protein in sapwood and heartwood, respectively. This enzymatic activity peaked at the 50th day of culture on sapwood for the Pa3 strain (17.618 mU/μg of protein) and at the 20th day of culture on heartwood for the Pa1 strain (12.203 mU/μg of protein). The activity of VP with manganese-oxidising properties was found to be high in all strains of P. abieticola, ranging 0–39.19 and 0–59.153 mU/μg of protein in sapwood and heartwood, respectively, whereas the activity of VP with guaiacol-oxidising properties was very low for all P. abieticola strains, ranging 0–0.248 and 0–0.225 mU/μg of protein in sapwood and heartwood, respectively. The values of released hydroxyphenols in P. abieticola strains ranged 24.915–139.766 and 25.19–84.562 µg of protocatechuic acid/ml in sapwood and heartwood, respectively. The values of released methoxyphenols for the evaluated strains of P. abieticola ranged 7.225–23.789 and 1.953–20.651 µg of vanillic acid/ml in sapwood and heartwood, respectively. Further studies with a higher number of strains of this species as well as an optimisation of conditions for the measurement of ligninolytic activity are needed.

Opis:
Doświadczenie laboratoryjne wykonano na Uniwersytecie Rolniczym w Krakowie, w Katedrze Ochrony Środowiska Rolniczego. Nasiona kukurydzy oraz bobiku zostały zaprawione zarodnikami grzyba owadobójczego Isaria fumosorosea w dawce 4,2 x 1011/1 kg nasion. Zarodniki grzyba owadobójczego pozyskano z hodowli na podłożu Sabouraud Dextrose Agar (SDA). Celem doświadczenia było określenie możliwości kolonizacji fyllosfery badanych roślin, a także gleby torfowej, do której zostały wysiane nasiona zaprawione zarodnikami grzyba owadobójczego. Uzyskane wyniki wskazują na możliwość zastosowania grzybów owadobójczych do zaprawiania materiału siewnego, wykorzystywanego w gospodarstwach ekologicznych. Wykazano, iż grzyb owadobójczy Isaria fumosorosea jest zdolny do kolonizacji fyllosfery kukurydzy oraz bobiku. Zaobserwowano występowanie grzyba na liściach badanych roślin. Do oceny kolonizacji gleby zastosowano metodę owadów pułapkowych, z wykorzystaniem larw mącznika młynarka (Tenebrio molitor L.). Stwierdzono, że grzyb Isaria fumosorosea szybko rozprzestrzenia się w podłożu i wykazuje dużą patogeniczność w stosunku do owadów testowych. Na podstawie uzyskanych wyników można wnioskować, iż grzyb owadobójczy Isaria fumosorosea może być wykorzystany do ochrony roślin przed szkodnikami zarówno glebowymi, jak i atakującymi nadziemne części roślin.
The experiment was conducted at the Uniwersity of Agriculture in Cracow. The aim of experiment was to evaluate the ability of entomopathogenic fungi to colonised plants phyllosphere and peat soil. The seeds of maize and faba bean were dressed with spores of entomopathogenic fungus Isaria fumosorsea (dose 4,2 x 1011 spores/1 kg seeds). I. fumosorosea was cultured on Sabouraud Dextrose Agar medium. The method of trap insects (larvae of Tenebrio molitor L.) was used for evaluation of soil colonization by I. fumosorosea. The occurrence of entomopathogenic fungus on plant leafs was also observed. The entomopathogenic fungus Isaria fumosorosea applied with seeds can quickly colonizes soil and the phyllosphere of plants. The entomopathogenic fungus I. fumosorosea may be used to protect plants against soil and aboveground insects. The results indicate the possibility of seed dressing with entomopathogenic fungi in ecological farms.

Opis:
We evaluated the efficacy of four different methods for endophytic inoculation of entomopathogenic fungus Beauveria bassiana in tomato plants. Fourteen days after inoculation, root dipping and leaf spraying allowed recovery of B. bassiana from leaves, while the fungus was recovered from roots in all inoculation methods, except soil drenching. Significant increases in mortalities of nymphs and adults of the greenhouse whitefly, 36 to 52%, were recorded on B. bassiana-endophyt plants. The total phenolic and protein contents of tomato plants were increased by endophyte colonization. Results of this study confirm the efficiency of foliar spraying of B. bassiana for colonization in tomato plants and its insecticidal activity against whitefly. The persistence of B. bassiana as endophyte was confirmed up to 56 days after inoculation. Given the insecticidal activity and beneficial effects of the endophyte on plant growth, B. bassiana could be considered as a suitable element in integrated pest management.
Oceniliśmy skuteczność czterech różnych metod endofitycznej inokulacji entomopatogennego grzyba Beauveria bassiana do pomidorów. 14 dni po zaszczepieniu stwierdzono obecność B. bassiana w liściach w przypadku inokulacji poprzez zanurzanie korzeni i oprysk liści, natomiast obecność grzyba w korzeniach stwierdzono przy wszystkich metodach inokulacji, z wyjątkiem zwilżania gleby. Na pomidorach zainfekowanych B. bassiana odnotowano znaczny wzrost śmiertelności nimf i osobników dorosłych mączlika szklarniowego, wynoszący od 36 do 52%. Całkowita zawartość fenoli i białka w tkankach pomidora wzrosła w wyniku kolonizacji endofitów. Wyniki badań potwierdzają skuteczność oprysku dolistnego B. bassiana w kolonizacji pomidora i jego owadobójcze działanie na mączlika szklarniowego. Trwałość B. bassiana jako endofitu została potwierdzona do 56 dni po inokulacji. Biorąc pod uwagę aktywność owadobójczą i korzystny wpływ endofitu na wzrost roślin, B. bassiana można uznać za odpowiedni element zintegrowanej ochrony roślin przed szkodnikami.
