such fungi like aspergillus spp ,fusarium spp &ergot is most common. please suggest some recently updated pathogens which have such lethal properties for plants and also for human and animals
Hello, as already mentioned the mycotoxins from fungi can form adducts with DNA and cause mutation which in some cases can be lethal.
Yes plant pathogens can also cause disease of humans and animals. You mention ergot which infects most rye and wheat and the infected grains can cause human and animal disease from mycotoxins.
Please take a look at this useful RG link.

Hello, as already mentioned the mycotoxins from fungi can form adducts with DNA and cause mutation which in some cases can be lethal.
Yes some plant diseases can cause severe diseases by humans and animals as well. Just one example: Aflatoxin produced by Aspergillus flavus found in moldy grains and meals (rice and peanut meal), Aflartoxin is suspected to cause liver cancer by human. Aspergillus flavus is sometimes responsible for the secondary infections in plants (corn for example) that have been attacked by insects such as Ostrinia nubilalis .
Dear Amir,
From the answers, there is no new other than you know. The most detrimental thing even lethal problems, caused by plant pathogens for human are sourced from faulty agricultural practices as little touched by some responds here (i.e. mycotoxins) and enhancement efforts of agricultural production and productivity by improper practices during their control.
Yes, As Jean-Pierre said, Aspergillus or Fusarium genus are involved in production of mycotoxins. More over, some Aspergillus species were known as alergogens.
So, take care. All The Best, C.
There are quite a number of plant pathogens that produce toxins capable of causing significant harm to humans if they are exposed to them. There are fewer that are capable of directly infecting and colonizing humans, and those tend to primarily affect immunosuppressed individuals. I am struggling to think of a plant pathogen that is capable of actually infecting and growing in a healthy individual but this is not my specific area of expertise.
Yes, Aflatoxin produced by Aspergillus flavus can diseases in humans and plants.
Mohd Amir Yes.
Some fusarium species are known to colonize stored cereal grains producing mycotoxins such as trichothecenes, zearalenone, and fumonisins that are harmful to humans and animals.
The most important species as far as human infection is concerned are Fusarium solani, F. moniliforme (=Fusarium verticilloides), F. oxysporum and F. dimerum Fusarium solani is also allergenic and is occasionally found in indoor environments
yes. of course some plant pathogens causing disease for animals and human , some fungus like Aspergillus flavus r producing mycotoxins and they are damaging for humans as well for animals. otherwise some endophytic bacteria isolated from plants tissues are not plant pathogenic for plants but can be pathogens for human and mammalia.
Mohd Amir Yes, Numerous plant pathogenic organisms infect Human beings and cause diseases.
generally post harvest rotting agents generally have toxic effects on human beings too. They may be bacteria or fungi mainly. Viral infections in planats and animal differ.
A couple that have not been mentioned are Mucor and Rhizopus. These are two of the primary genera that can cause mucormycoses. This is a problem particularly for immunocompromised people (https://www.cdc.gov/fungal/diseases/index.html). Note that Aspergillus species, as well as producing mycotoxins as mentioned by others, also can be directly pathogenic, causing aspergillosis in susceptible individuals. Some Fusarium species can infect eyes of even healthy individuals. Several other plant pathogens have been found occasionally infecting people, mostly those who have problems with their immune systems. I know more of fungi, but have seen some reports of Pantoea species that can infect both plants and humans (e.g. Article Pantoea ananatis: An unconventional plant pathogen
).
yes plant pathogens and their products (Aflatoxin) cause in human beings. Except Plant viruses which can't cause diseases in human beings
In terms of mycotoxins Fusarium diseases can lead to many issues in animals and humans.
The Wikipedia has some good overview. Attached is a word version.
I agree with Linda answer . However there is a big differences between Mycosis and Mycotoxicosis. Mycosis is tissue invasion by a fungi and mycotoxicosis is toxin production by a fungi growing on foodstuffs which is then ingested causing disease. Some fungi like Aspergillus fumigatus cause disease to humans called aspegillosis
Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. The majority of cases occur in people with underlying illnesses such as tuberculosis[1] or chronic obstructive pulmonary disease, but with otherwise healthy immune systems.[2] Most commonly, aspergillosis occurs in the form of chronic pulmonary aspergillosis (CPA), aspergilloma or allergic bronchopulmonary aspergillosis (ABPA).[3] Some forms are intertwined; for example ABPA and simple aspergilloma can progress to CPA.

Mohammed sir, Aspergillus fumigatus please give name of disease cause in plant or crop. Thanking you
Dear Dharmesh. In my answer ,i tried to differentiate between Mycosis and Mycotoxicosis ,and i did not mean that A.fumigatus can cause disease to plant However there is few fungi which can cause diseases to plant and human such as Mucor spp which can cause fruit decay and Mycormycosis to human suffering from leukaemia ,Aids and diabetes .

Aspergillus fumigatus: saprophyte or pathogen?

Large-scale genome comparisons have shown that no gene sets are shared exclusively by both Aspergillus fumigatus and any other human pathogen sequenced to date, such as Candida or Cryptococcus species. By contrast, and in agreement with the environmental occurrence of this fungus in decaying vegetation, the enzymatic machinery required by a fungus to colonize plant substrates has been found in the A. fumigatus genome. In addition, the proteome of this fungus contains numerous efflux pumps, including >100 major facilitators that help the fungus to resist either natural aggressive molecules present in the environment or antifungal drugs in humans. Environment sensing, counteracting reactive oxidants, and retrieving essential nutriments from the environment are general metabolic traits that are associated with the growth of the saprotrophic mold A. fumigatus in an unfriendly environment such as its human host.
Alternaria alternata is a fairly common indoor mould. In one study it was found in 87% of the homes examined. It is considered one of the most important fungal allergens. Alternaria alternata has been implicated as the cause of allergic diseases in people exposed to wood and sawdust during paper production in paper mills. It is regarded as the main cause of allergy and asthma in children aged 6–11 years.

ABSTRACT
The genus Alternaria contains several species of melanized hyphomycetes that cause opportunistic human infections. The published literature contains 210 reported cases of human alternarioses between 1933 and the present day. The most frequent clinical manifestations are cutaneous and subcutaneous infections (74.3%), followed by oculomycosis (9.5%), invasive and non-invasive rhinosinusitis (8.1%) and onychomycosis (8.1%). Immunosuppression is frequently associated with cutaneous and subcutaneous infections and rhinosinusitis. The most important risk factors for cutaneous and subcutaneous infections are solid organ transplantation and Cushing's syndrome, and those for rhinosinusitis are bone marrow transplants. Having been exposed to soil and garbage is common in all cases of oculomycosis, with corticotherapy being a risk factor in 50% of these cases. Previous contact with soil and/or trauma to the nails is associated with most cases of onychomycosis. In general, alternariosis shows a good response to conventional antifungal drugs. On some occasions, steroid suppression or reduction is sufficient to resolve an infection. Itraconazole is the antifungal drug used most frequently to successfully treat onychomycosis and cutaneous and subcutaneous infections. Posaconazole and voriconazole are promising therapeutic options, with the latter being especially so for oculomycosis.
No, plant pathogens do not generally infect or cause diseases in humans.
There are a few exceptions to the rule such as the bacterial Pseudomonas spp that can infect immunocompromised individuals and the fungus Sporothrix that causes sporotrichosis.
So the answer to this question is an absolute no, with a few exceptions to this rule.
