A new antibiotic CJ-17,665 from Aspergillus ochraceus. (1/15)

A new antibiotic, CJ-17,665 (I) was isolated from the fermentation broth of Aspergillus ochraceus, CL41582. It inhibits growth of multi-drug resistant Staphylococcus aureus, Streptococcus pyogenes, and Enterococcus faecalis, with MICs of 12.5, 12.5 and 25 microg/ml, respectively. The structure contains a diketopiperazine and an indole N-oxide moiety that is unusual in natural products.  (+info)

Ochratoxin production by the Aspergillus ochraceus group and Aspergillus alliaceus. (2/15)

Ochratoxin A is a toxic and carcinogenic fungal secondary metabolite; its presence in foods is increasingly regulated. Various fungi are known to produce ochratoxins, but it is not known which species produce ochratoxins consistently and which species cause ochratoxin contamination of various crops. We isolated fungi in the Aspergillus ochraceus group (section Circumdati) and Aspergillus alliaceus from tree nut orchards, nuts, and figs in California. A total of 72 isolates were grown in potato dextrose broth and yeast extract-sucrose broth for 10 days at 30 degrees C and tested for production of ochratoxin A in vitro by high-pressure liquid chromatography. Among isolates from California figs, tree nuts, and orchards, A. ochraceus and Aspergillus melleus were the most common species. No field isolates of A. ochraceus or A. melleus produced ochratoxin A above the level of detection (0.01 microg/ml). All A. alliaceus isolates produced ochratoxin A, up to 30 microg/ml. We examined 50,000 figs for fungal infections and measured ochratoxin content in figs with visible fungal colonies. Pooled figs infected with A. alliaceus contained ochratoxin A, figs infected with the A. ochraceus group had little or none, and figs infected with Penicillium had none. These results suggest that the little-known species A. alliaceus is an important ochratoxin-producing fungus in California and that it may be responsible for the ochratoxin contamination occasionally observed in figs.  (+info)

Bilirubin dehydrogenase, an enzyme in Aspergillus ochraceus IB-3 useful for diagnostic measurement of bilirubin. (3/15)

Bilirubin dehydrogenase, a membrane-bound enzyme that catalyzes the one-step oxidation of ditaurobilirubin and bilirubin to ditaurobiliverdin and biliverdin, respectively, in the presence of an electron acceptor, was found in Aspergillus ochraceus IB-3, and purified from the membrane fraction through solubilization by Triton X-100. Phenazine and quinone derivatives acted as electron acceptors. Accumulation of ditaurobiliverdin and biliverdin by enzyme catalysis increased the absorbance at 660 nm, which is far from the range of wavelengths affected by serum ingredients. The enzyme selectively oxidized ditaurobilirubin at low pH, so changes in the reaction pH enable the enzyme to discriminate between the bilirubin fractions ditaurobilirubin (an example of conjugated bilirubin) and bilirubin (an example of unconjugated bilirubin). Using the enzyme, 2 to 80 microM of ditaurobilirubin were measured accurately by monitoring the changes in absorbance at 660 nm.  (+info)

A polyketide synthase gene required for ochratoxin A biosynthesis in Aspergillus ochraceus. (4/15)

Ochratoxin A is an important nephrotoxic and nephrocarcinogenic mycotoxin, produced by Aspergillus ochraceus as a polyketide-derived secondary metabolite. A portion of a putative polyketide synthase gene (pks) involved in the biosynthesis of this mycotoxin was cloned by using a suppression subtractive hybridization PCR-based approach. The predicted amino acid sequence of the 1.4 kb clone shared 28-35 % identity to acyl transferase regions from fungal polyketide synthases found in the databases. Based on reverse transcription PCR studies, the pks gene is expressed only under ochratoxin A permissive conditions and only during the early stages of the mycotoxin synthesis. A mutant in which the pks gene has been interrupted cannot synthesize ochratoxin A. This report is the first of the cloning and characterization of a gene involved in ochratoxin A biosynthesis.  (+info)

Variants of Aspergillus alutaceus var. alutaceus (formerly Aspergillus ochraceus) with altered ochratoxin A production. (5/15)

The present studies, using Aspergillus alutaceus var. alutaceus Berkeley et Curtis (formerly A. ochraceus Wilhelm) NRRL 3174 along with three other wild-type strains, were undertaken in an attempt to understand the effects of irradiation and other treatments on mycotoxin production in grain. Bedford barley was inoculated with spores of NRRL 3174, gamma irradiated, and incubated at 28 degrees C and 25% moisture. After 10 days of incubation, two colony types, ochre (parental) and yellow (variant), were isolated from the grain. Further culturing of the yellow variant resulted in the spontaneous appearance of a white variant that exhibited greatly enhanced fluorescence under UV light. In subsequent work, we have also isolated variants producing a soluble red pigment. In addition, in model experiments involving irradiation (1 kGy) of pure cultures, induction frequencies ranging between 2 and 4% (survival basis) were observed for the yellow and red variants. Inoculation of these variants into wheat and incubation for 14 days at 28 degrees C and 32% moisture resulted in ochratoxin A production in the relative amounts of 0.09:1:4.6:9.3 for the red, ochre (parental), yellow, and white variants, respectively. Additional characteristics of these isolates are described. Confirmation that the white high-ochratoxin-A-producing variants were derived from the parental strain was demonstrated by obtaining revertant sectors in monoclonal cultures of the variants.  (+info)

Role of the competitive microbial flora in the radiation-induced enhancement of ochratoxin production by Aspergillus alutaceus var. alutaceus NRRL 3174. (6/15)

The radiation sensitivity and the toxigenic potential of conidiospores of the fungus Aspergillus alutaceus var. alutaceus were determined after irradiation with 60Co gamma rays and high-energy electrons. Over the pH range of 3.6 to 8.8, the doses required for a 1 log10 reduction in viability based on the exponential portion of the survival curve ranged from 0.21 to 0.22 kGy, with extrapolation numbers (extrapolation of the exponential portion of the survival curve to zero dose) of 1.01 to 1.33, for electron irradiation, and from 0.24 to 0.27 kGy, with extrapolation numbers of 2.26 to 5.13, for gamma irradiation. Nonsterile barley that was inoculated with conidia of the fungus and then irradiated with either electrons or gamma rays and incubated for prolonged periods at 28 degrees C and at a moisture content of 25% produced less ochratoxin A with increasing doses of radiation. Inoculation of barley following irradiation resulted in enhanced ochratoxin levels compared with unirradiated controls. In these experiments, inoculation with 10(2) spores per g produced greater radiation-induced enhancement than inoculation with 10(5) spores per g. There was no radiation-induced enhancement when the barley was surface sterilized by chemical means prior to irradiation. These results are consistent with the hypothesis that a reduction in the competing microbial flora by irradiation is responsible for the enhanced mycotoxin production observed when nonsterile barley is inoculated with the toxigenic fungus A. alutaceus var. alutaceus after irradiation.  (+info)

Characterization of alcohol oxidase from Aspergillus ochraceus AIU 031. (7/15)

An alcohol oxidase (AOD) was found from Aspergillus ochraceus AIU 031, and its characteristics were revealed. This enzyme oxidized short-chain primary alcohols and ethylene glycol, and belonged to the same group as AOD from methylotrophic yeast. However, it differed in the following properties. The K(m) value for ethanol was larger and that for ethylene glycol was smaller than those of AODs derived from methylotrophic yeasts. The ethanol oxidation was optimal at pH 5-7 and 50-55 degrees C. The molecular mass of this enzyme was 262 kDa and consisted of four identical subunits of 68 kDa, which were much smaller than those of methylotrophic yeasts.  (+info)

'Aspergillus ochraceus' is a species of fungi that belongs to the genus Aspergillus. The term 'Aspergillus ochraceus' is used in medical and scientific contexts to refer to this specific type of fungus. It is commonly found in soil, decaying vegetation, and other organic matter, and can also be found in indoor environments such as air conditioning systems, carpeting, and drywall.

While 'Aspergillus ochraceus' is not typically associated with human disease, it can cause invasive aspergillosis in individuals with weakened immune systems, particularly those who have undergone organ transplants or have certain types of cancer. The fungus can also produce toxins that can cause allergic reactions and other health problems in some people.

It's worth noting that while 'Aspergillus ochraceus' is a specific species of fungi, there are many other species of Aspergillus that can also cause human disease, including the more common 'Aspergillus fumigatus'.

Ochratoxins are a type of mycotoxin, which are toxic compounds produced by certain types of molds or fungi. Specifically, ochratoxins are produced by several species of Aspergillus and Penicillium molds that can contaminate a variety of agricultural crops, such as grains, nuts, coffee beans, dried fruits, and wine.

Ochratoxin A is the most prevalent and studied member of this family of mycotoxins. It is known to have nephrotoxic, immunotoxic, teratogenic, and carcinogenic effects in various animal species. In humans, exposure to ochratoxin A has been linked to kidney disease, developmental toxicity, and possibly cancer.

Ochratoxins can enter the human body through the consumption of contaminated food or drink. Once inside, they can accumulate in tissues, particularly in the kidneys, where they can cause damage over time. It is important to note that exposure to ochratoxins should be minimized to reduce the risk of health effects.

"Aspergillus" is a genus of filamentous fungi (molds) that are widely distributed in the environment. These molds are commonly found in decaying organic matter such as leaf litter, compost piles, and rotting vegetation. They can also be found in indoor environments like air conditioning systems, dust, and building materials.

The medical relevance of Aspergillus comes from the fact that some species can cause a range of diseases in humans, particularly in individuals with weakened immune systems or underlying lung conditions. The most common disease caused by Aspergillus is called aspergillosis, which can manifest as allergic reactions, lung infections (like pneumonia), and invasive infections that can spread to other parts of the body.

Aspergillus species produce small, airborne spores called conidia, which can be inhaled into the lungs and cause infection. The severity of aspergillosis depends on various factors, including the individual's immune status, the specific Aspergillus species involved, and the extent of fungal invasion in the body.

Common Aspergillus species that can cause human disease include A. fumigatus, A. flavus, A. niger, and A. terreus. Preventing exposure to Aspergillus spores and maintaining a healthy immune system are crucial steps in minimizing the risk of aspergillosis.

Mycotoxins are toxic secondary metabolites produced by certain types of fungi (molds) that can contaminate food and feed crops, both during growth and storage. These toxins can cause a variety of adverse health effects in humans and animals, ranging from acute poisoning to long-term chronic exposure, which may lead to immune suppression, cancer, and other diseases. Mycotoxin-producing fungi mainly belong to the genera Aspergillus, Penicillium, Fusarium, and Alternaria. Common mycotoxins include aflatoxins, ochratoxins, fumonisins, zearalenone, patulin, and citrinin. The presence of mycotoxins in food and feed is a significant public health concern and requires stringent monitoring and control measures to ensure safety.

"Kloeckera" is not a term that has a widely accepted medical definition. It is a genus of budding yeasts that are commonly found in nature, particularly on the surfaces of fruits and plants. They are often associated with the fermentation process and can be found in various food and drink products. In a medical context, "Kloeckera" species may occasionally be mentioned in relation to certain types of infections, such as fungal skin infections, but they are not typically considered primary human pathogens.

It's worth noting that the taxonomy of yeasts is complex and constantly evolving, and some species that were previously classified under the genus "Kloeckera" have since been reclassified under other genera, such as "Hanseniaspora." Therefore, it's essential to consult the most recent scientific literature for accurate and up-to-date information on this topic.

"Penicillium" is not a medical term per se, but it is a genus of mold that is widely used in the field of medicine, specifically in the production of antibiotics. Here's a scientific definition:

Penicillium is a genus of ascomycete fungi that are commonly found in the environment, particularly in soil, decaying vegetation, and food. Many species of Penicillium produce penicillin, a group of antibiotics with activity against gram-positive bacteria. The discovery and isolation of penicillin from Penicillium notatum by Alexander Fleming in 1928 revolutionized the field of medicine and led to the development of modern antibiotic therapy. Since then, various species of Penicillium have been used in the industrial production of penicillin and other antibiotics, as well as in the production of enzymes, organic acids, and other industrial products.

Coumarins are a class of organic compounds that occur naturally in certain plants, such as sweet clover and tonka beans. They have a characteristic aroma and are often used as fragrances in perfumes and flavorings in food products. In addition to their use in consumer goods, coumarins also have important medical applications.

One of the most well-known coumarins is warfarin, which is a commonly prescribed anticoagulant medication used to prevent blood clots from forming or growing larger. Warfarin works by inhibiting the activity of vitamin K-dependent clotting factors in the liver, which helps to prolong the time it takes for blood to clot.

Other medical uses of coumarins include their use as anti-inflammatory agents and antimicrobial agents. Some coumarins have also been shown to have potential cancer-fighting properties, although more research is needed in this area.

It's important to note that while coumarins have many medical uses, they can also be toxic in high doses. Therefore, it's essential to use them only under the guidance of a healthcare professional.

'Aspergillus fumigatus' is a species of fungi that belongs to the genus Aspergillus. It is a ubiquitous mold that is commonly found in decaying organic matter, such as leaf litter, compost, and rotting vegetation. This fungus is also known to be present in indoor environments, including air conditioning systems, dust, and water-damaged buildings.

Aspergillus fumigatus is an opportunistic pathogen, which means that it can cause infections in people with weakened immune systems. It can lead to a range of conditions known as aspergillosis, including allergic reactions, lung infections, and invasive infections that can spread to other parts of the body.

The fungus produces small, airborne spores that can be inhaled into the lungs, where they can cause infection. In healthy individuals, the immune system is usually able to eliminate the spores before they can cause harm. However, in people with weakened immune systems, such as those undergoing chemotherapy or organ transplantation, or those with certain underlying medical conditions like asthma or cystic fibrosis, the fungus can establish an infection.

Infections caused by Aspergillus fumigatus can be difficult to treat, and treatment options may include antifungal medications, surgery, or a combination of both. Prompt diagnosis and treatment are essential for improving outcomes in people with aspergillosis.

'Aspergillus nidulans' is a species of filamentous fungi that belongs to the genus Aspergillus. It is commonly found in soil, decaying vegetation, and indoor environments such as air conditioning systems and damp buildings. This fungus can produce spores that become airborne and can be inhaled, which can cause respiratory infections in individuals with weakened immune systems.

'Aspergillus nidulans' is also a widely used model organism in scientific research, particularly in the fields of genetics, molecular biology, and cell biology. Its genetic tractability, short life cycle, and ability to grow at a wide range of temperatures make it an ideal system for studying fundamental biological processes such as DNA repair, cell division, and metabolism. Additionally, this fungus is known to produce a variety of secondary metabolites, including pigments, antibiotics, and mycotoxins, which have potential applications in medicine and industry.

I believe you may be mistakenly using the term "starfish" to refer to a medical condition. If so, the correct term is likely " asterixis," which is a medical sign characterized by rapid, rhythmic flapping or tremulous movements of the hands when they are extended and the wrist is dorsiflexed (held with the back of the hand facing upwards). This is often seen in people with certain neurological conditions such as liver failure or certain types of poisoning.

However, if you are indeed referring to the marine animal commonly known as a "starfish," there isn't a specific medical definition for it. Starfish, also known as sea stars, are marine animals belonging to the class Asteroidea in the phylum Echinodermata. They have a distinctive shape with five or more arms radiating from a central disc, and they move slowly along the ocean floor using their tube feet. Some species of starfish have the ability to regenerate lost body parts, including entire limbs or even their central disc.

Fungi, in the context of medical definitions, are a group of eukaryotic organisms that include microorganisms such as yeasts and molds, as well as the more familiar mushrooms. The study of fungi is known as mycology.

Fungi can exist as unicellular organisms or as multicellular filamentous structures called hyphae. They are heterotrophs, which means they obtain their nutrients by decomposing organic matter or by living as parasites on other organisms. Some fungi can cause various diseases in humans, animals, and plants, known as mycoses. These infections range from superficial, localized skin infections to systemic, life-threatening invasive diseases.

Examples of fungal infections include athlete's foot (tinea pedis), ringworm (dermatophytosis), candidiasis (yeast infection), histoplasmosis, coccidioidomycosis, and aspergillosis. Fungal infections can be challenging to treat due to the limited number of antifungal drugs available and the potential for drug resistance.

'Aspergillus niger' is a species of fungi that belongs to the genus Aspergillus. It is a ubiquitous microorganism that can be found in various environments, including soil, decaying vegetation, and indoor air. 'Aspergillus niger' is a black-colored mold that produces spores that are easily dispersed in the air.

This fungus is well known for its ability to produce a variety of enzymes and metabolites, some of which have industrial applications. For example, it is used in the production of citric acid, which is widely used as a food additive and preservative.

However, 'Aspergillus niger' can also cause health problems in humans, particularly in individuals with weakened immune systems or underlying lung conditions. It can cause allergic reactions, respiratory symptoms, and invasive aspergillosis, a serious infection that can spread to other organs in the body.

In addition, 'Aspergillus niger' can produce mycotoxins, which are toxic compounds that can contaminate food and feed and cause various health effects in humans and animals. Therefore, it is important to prevent the growth and proliferation of this fungus in indoor environments and food production facilities.

Thin-layer chromatography (TLC) is a type of chromatography used to separate, identify, and quantify the components of a mixture. In TLC, the sample is applied as a small spot onto a thin layer of adsorbent material, such as silica gel or alumina, which is coated on a flat, rigid support like a glass plate. The plate is then placed in a developing chamber containing a mobile phase, typically a mixture of solvents.

As the mobile phase moves up the plate by capillary action, it interacts with the stationary phase and the components of the sample. Different components of the mixture travel at different rates due to their varying interactions with the stationary and mobile phases, resulting in distinct spots on the plate. The distance each component travels can be measured and compared to known standards to identify and quantify the components of the mixture.

TLC is a simple, rapid, and cost-effective technique that is widely used in various fields, including forensics, pharmaceuticals, and research laboratories. It allows for the separation and analysis of complex mixtures with high resolution and sensitivity, making it an essential tool in many analytical applications.

'Aspergillus flavus' is a species of fungi that belongs to the genus Aspergillus. It is commonly found in soil, decaying vegetation, and other organic matter. This fungus is known for its ability to produce aflatoxins, which are highly toxic compounds that can contaminate food crops such as corn, peanuts, and cottonseed.

Aflatoxins produced by A. flavus are among the most potent carcinogens known to humans and can cause liver damage and cancer with prolonged exposure. The fungus can also cause invasive aspergillosis, a serious infection that primarily affects people with weakened immune systems, such as those undergoing chemotherapy or organ transplantation.

In addition to its medical importance, A. flavus is also used in biotechnology for the production of industrial enzymes and other products.

Culture media is a substance that is used to support the growth of microorganisms or cells in an artificial environment, such as a petri dish or test tube. It typically contains nutrients and other factors that are necessary for the growth and survival of the organisms being cultured. There are many different types of culture media, each with its own specific formulation and intended use. Some common examples include blood agar, which is used to culture bacteria; Sabouraud dextrose agar, which is used to culture fungi; and Eagle's minimum essential medium, which is used to culture animal cells.
