    Opis:
    Naturally occurring entomopathogens are important regulatory factors of insect populations. Among them are entomopathogenic fungi. The invasion of insects by parasitic fungi occurs through penetration of the host integument. Death of the host is a result of tissue destruction, exhaustion of nutrients or the production of toxins. Conidiobolus coronatus (Entomophthorales) is a saprophytic soil fungus that kills insects by releasing toxins inside insect body, before the invasion of host's organs and tissues by fungal hyphae. It is pathogenic to a number of insects and could be relatively easily propagated in laboratory conditions. The fungus is an interesting object to study and might be the source of new insecticidal substances as well. The main aim of the study was isolation and characterisation of active compounds produced by C. coronatus. In experimental surveys of interactions between insects and entomopathogenic fungi it is important to establish simple and reliable method of quantification of fungal pathogenicity towards insects, and to chose right insect target as well. Four methods were tested on two species — Galleria mellonella and Dendrolimus pini: (1) immersing larvae in conidial suspension; (2) deposition the conidia on the cuticle; (3) injection into hemocoel, and (4) exposure to fungal colony. Exposition of G. mellonella larvae to fungal colony was chosen, as the best method to quantify C. coronatus pathogenicity, reflecting possible contact of insects with fungal spores in nature. D. pini larvae were not chosen to further experiments. Dark colour of their body disables the estimation of fungal infection progress. The fungus produces an array of enzymes regarded as necessary in efficient penetration of insect cuticle: proteases, chitinases and lipases, which degrade the components of the integument. The activity of those enzymes was measured in mycelial homogenates and in post incubation media. In homogenates the activity of elastase, N−acetylglucosaminidase (NAGase) and lipase was denoted. The homogenate had no chymotripsin and chitinase activity. In the incubation media the activity of five examined enzymes was present. Elastase and NAGase activities were much higher than those of three other enzymes. The long term observation of four colonies in laboratory conditions from one transfer to another revealed differences in the ability to kill G. mellonella larvae. The colonies reduced pathogenicity during several transfers and then relapsed into higher level of pathogenicity again. The fluctuations were more or less regular and appeared through two−year duration of the experiment. The nature of this fluctuation is unknown and no similar phenomenon was observed elsewhere. To elicit the possible background of instability of fungal cultures towards G. mellonella, a genetic analysis was performed on colonies derived from primary conidia, containing several dozen of nuclei, and microconidia, which are formed on the surface of primary conidia and containing a maximum several nuclei. Both analyses: DNA Fingerprinting and Amplified Fragments Length Polymorphism (AFLP) revealed that colonies isolated from primary conidia or microconidia differ in the genetic profile. The genetic differences reflect the differences in the pathogenicity trait. Genetic analysis of colonies derived from microconidia proved that nuclei differ genetically, which means that C. coronatus mycelium is heterokaryotic. A chromatographic separation of fungal homogenate proteins did not succeed. Better possibility gave the separation of proteins released by fungus to minimal medium. By two step high pressure liquid chromatography: size exclusion and ion exchange four proteins were separated to homogeneity, according to SDS−PAGE. Two of them in the size 14.5 kDa and 36 kDa were moderately pathogenic to G. mellonella larvae in the dose of 1µg per larva (20% and 10% of pathogenicity, respectively), and exhibited no enzymatic activity. Third protein was a 33−34 kDa elastase with no pathogenic effect. The last protein in the size 36−37 kDa was pathogenic to the larvae (20%) and exhibited elastolytic and chitinolytic activities. Further experiments will elicit the mode of actions on cell cultures of those four isolated proteins.

    Opis:
    Nosema ceranae was discovered in Apis cerana, Eastern honeybee first. Until recently A. cerana has been considered the only host to this parasite. A few years ago N. ceranae was recorded in honey bee Apis mellifera. It appeared that N. ceranae is more pathogenic for A. mellifera than Nosema apis. This parasite can cause significant losses in bee colonies. Bees die without symptoms observed in nosemosis caused by N. apis such as diarrhea.

    Opis:
    Occurrence of Pneumocystis carinii DNA aod anti-Pneumocystis antibodies in sera of infants at the age of humoral response natural degradation. The polymerase chain reaction (PCR) and indirect immunofluorescent test (IF) were used for examination of serum samples obtained from infants with respiratory tract infections. Sixty (11,9%) out of the 503 examined infant samples were positive for anti-P. carinii IgM and 354 (70,4%) contained anti-Pneumocystis IgG. P. carinii DNA was found in 6 (6,7%) sera from 90 of infected infants. Five out these 6 samples were for anti-Pneumocystis antibodies positive; 4 contained both IgG and IgM classes and one bad only IgG. The sixth sample had neither IgG nor IgM, despite of P. carinii DNA presence. The results of the studies indicated that for diagnosis Pneumocystis carinii pneumonia (PCP) in infants on serum specimens detection of antibodies by IF test is of greater value than Pneumocystis DNA amplification by PCR method.

    Opis:
    The largest problem in limitation of insect pest population is increasing resistance of them to chemical pesticides. Alternative are entomopathogens, which regulate frequency of insect pests. Among them decisive role play entomopathogenic fungi, which possess the ability to active penetration through cuticle by mechanical pressure of invasive hypha and production of proteo-, chitino- (egzo- and endochitinases) as well as lipolytic enzymes, which provide nutrients for subsequent development of fungus. Entomopathogenic soil fungus Conidiobolus coronatus (Entomophtorales) is saprophyte fungus, which demonstrates a high efficiency in the paralysis of varied insects. Although leading investigations over mechanism of insect paralysis, we still do not know, what role fungal enzymes play in insect cuticle penetration. The main aim of research was establishment of optimal conditions for elastase, N-acetylglucosaminidase (NAGase), chitobiosidase as well as lipase. Optimal reaction parameters were determined: volume of reaction mixture, volume of homogenate, working pH and the substrate concentration. Having on aim a possible use of C. coronatus in pest control, two ranges of temperatures were chosen: 20°C – optimal temperature for the fungus growing and 30°C – optimal temperature for the cultivation of the great wax moth larvae, Galleria mellonella, on which examinations were performed. Also kinetic constants Km and Vmax were determined. Activity of elastase and N-acetylglucosaminidase of C. coronatus was measured spectrophotometrically at 410 nm (towards N-Succinyl-Ala-Ala-Pro-Leu-p-Nitroanilide) and 405 nm (towards 4-Nitrophenyl-N-acetyl-b-D-glucosaminide), respectively. The following optimal conditions of elastase activity were established: the volume of reaction mixture 0.5 ml, volume of homogenate 1 ml, temperature 30°C, pH 8, substrate concentration 40 mM. Optimal conditions of NAGase assay: the volume of reaction mixture 0.5 ml, dose of homogenate 12.5 ml, temperature 30°C, pH neutral and 6 mM substrate concentration. The activities of chitobiosidase and lipase were measured spectrofluorometrically (Ex=360 nm, Em=450 nm) towards 4-Methylumbelliferyl b-D-N-N’-diacetylchitobioside and 4-Methylumbelliferyl oleate, respectively. Chitobiosidase showed the highest activity in dose of 30 ml in 1 ml volume of reaction mixture, at the temperature of 30°C, pH 7 and substrate concentration equal to 2 mM. Lipase showed the highest catalytic activity in 1 ml volume of reaction mixture, in 30°C but 50 ml of homogenate, pH 10 and 10 mM substrate concentration were needed. Higher activity investigated enzymes in 30°C than 20°C indicated that they can take part in pathogenesis. It was suggested that as first in perforation of coats of insects body elastase and lipase take part. Indicated of it, large thermoresistance of both enzymes (only 10.5% decrease of elastase activity at 20°C and 9.4% decrease of lipase activity in comparison with maximal activity at 30°C), alkalophilicity of both proteins (elastase shows the alkaline optimal pH equal to 8 at pH 9 preserves 97% activity, and at pH 10 94% activity, respectively while lipase prefers the pH 10 and at pH 8 and pH 9 enzyme keeps 57 and 60% activity, respectively) as well as lack of repression by suitable substrates. Sigmoid character of curve concerning pH influence on the activity of both enzymes, also indicates similarity between elastase and lipase. On minor part of NAGase and chitobiosidase of fungus C. coronatus in perforation of coats of host body showed high sensibility of both enzymes on hydrogen ions concentration: both enzymes prefer neutral pH, in pH 6 and 8 lose over 35% activity but subjection to substrate repression and 3–4-fold growth of activity followed only in 30°C. In the course of work it was found, that rich medium (LB) stimulates growth of mycelium and production of fungal lipases. So far nobody managed to isolate chitinolytic or lipolytic enzymes from C. coronatus homogenate. The majority of fungal enzymes were isolated from post incubation filtrates. In the literature of the subject lack of data about C. coronatus NAGase, therefore in examinations also the trial of isolation NAGase from C. coronatus homogenate was undertaken. Activity of NAGase showed only first fraction, which did not separate with none of used columns. Disappointing results of purification on cation exchanger CM, weak anion exchanger DEAE, and strong anion exchanger Q were obtained as well as after fractionation tests with the use of Microcon microcolumns. In aim of NAGase molecular mass estimation, two zymograms were made with Triton X-100 and casein and with the use of fluorescent substrate 4-Methylumbelliferyl N-acetyl-b-D-glucosaminide. Molecular mass of NAGase from C. coronatus was established on ca. 60 kDa. This is the first report describing molecular weight of NAGase from C. coronatus. Examined NAGase has different properties than known NAGases from other entomopathogenic fungi. Although its molecular weight is equal to the Metarhizium anisopliae NAGase, optimal pH for both NAGases are different: neutral in the case of C. coronatus NAGase versus acidic in the case of M. anisopliae NAGase. Knowledge of molecular mass of the C. coronatus NAGase should allow to find a new method of this enzyme isolation from C. coronatus homogenate. Thanks to developed methods of assaying activities of elastase, NAGase, chitobiosidase and lipase, real becomes the understanding of mechanism of insects paralysis through C. coronatus fungus.

    Opis:
    The soils ecosystem plays an important role in the epidemiology of geohelminth diseases of humans and animals. Soil contamination with ova of the parasitic geohelminths represents a global public health-hazard issue. Biological agents have been thought to control the infective forms of parasites present in the soil. Biocontrol of geohelminths represents an alternative to pesticides (i.e., nematicides), which are not efficient in killing infective nematode forms and, additionally, result in the environment pollution and long-term disturbances in the soil ecosystem homeostasis. The degree of the inhibiting effect of soil saprotrophic fungi on geohelminth embryonic development varies and depends on the species. A number of fungi cause various morphological disorders in the embryos of developing parasitic nematodes, but also have an ovicidal effect. Although the nature of the antagonism between fungi and other living organisms has not been fully explained, it is certain that mycotoxins and fungal enzymes constitute its important components. Considering the studies carried out so far, the antagonistic effect of mold fungi against the infective stages of geohelminths can be fully recommended as a real control factor, especially as these saprotrophs represent a natural factor within the soil environment, that is of particular biochemical activity.

    Opis:
    The state of knowledge on the possible antagonism between soil saprotrophic fungi and phytopathogenic nematodes of the genera Meloidogyne, Heterodera, and Globodera is reviewed basing on the literature and our own research. Mycelial colonisation of various developmental stages of these geohelminths is the most common factor thought to reduce their populations in nature. The following parasitic fungi can be found on the cysts, eggs, as well as the larvae of the nematodes: Paecilomyces lilacinus, Verticillium chlamydosporium, Cylindrocarpon destructans, Pochonia chlamydosporia, Fusarium spp., and Penicillium spp. The fungi invade the nematodes, such as Heterodera, Globodera, or Meloidogyne, „passively” penetrating through the natural orifices of the cysts, eggs, and larvae of the host. Equally frequent, however, is a biochemical action of the fungi prior to colonisation, which is linked with production of mycotoxins or hydrolytic enzymes. Such an active way of fungal penetration of various stages of the phytopathogenic nematodes has been observed in Pochonia chlamydosporia, Penicillium verrucosum var. cyclopium, P. frequentans, Sclerotinia rolfsii, Rhizoctonia solani, and Fusarium spp. Triacylglycerols (TAG), phenols, as well as trichothecene, T-2, have been found in the metabolites extracted from mycelia of these species. Predation by fungi is also a factor that may reduce a population of phytopathogenic nematodes. This form of antagonism is characteristic for nematicidal fungi of the genera Arthrobotrys and Dactylella. These fungi form shrinking rings and hooks in their mycelia by which the fungus entangles and paralyses a migrating form of nematode. Despite the fact that the antagonism between fungi and nematodes is a commonly occurring phenomenon observed in the soil, the nematicidal and nematotoxic properties of fungi have not a wide application in biological plant protection. Up till now, only the bionematicides based on Arthrobotrys robusta (Royal 300 and Royal 350) as well as Paecilomyces lilacinus (Biocon and PL Plus) have found its commercial application.

    Cryptococcus neoformans is the causative agent of cryptococcosis and cryptococcal meningitis, which are serious pathological conditions affecting up to 10% of patients with AIDS. In this paper we present results magnetic resonance imaging and spectroscopic metabolites (1H MR) in brain cryptococcosis. In 1HMR spectroscopy we tind decreased metabolic ratios to nonsaturated water (H2O) signal N-acetylaspartate (NA/H20, creatine (Cr/H20), choline (Cho/H20). We show increased mioinositol to H2O ratio. Spectroscopy results suggest about massive neuronal injury and accompanying gliosis in brain cryptococcosis.
