Some plant pathogens are also serious threats to human health. Pathogenic fungi from the genera Alternaria, Aspergillus, Bipolaris, Cladosporium, Claviceps, Fusarium, Paecilomyces and Exserohilum, and some bacteriaa genera including Burkholderia, Enterobacter, Enterococcus, Escherichia, Erwinia, Pantoea, Pseudomonas, Salmonella, Serratia and Xanthomonas can cause harmful diseases in human. Diseases caused by these microorganisms in plants and human are described here and some researches to identify them on raw fruits and vegetables are suggested.

Nasiri M, Faghihi M M (2022)Bacterial mosaic disease of wheat. Plant Pathology Science 11(2):103-111.
Bacterial mosaic of wheat is caused by the gram positive bacterium Clavibactertessellarius. The symptoms of the disease are uniformly distributed small chlorotic spots with mosaic pattern on the entire leaf surface resemble those symptoms of nutrient deficiencies and some viral diseases, and it may be difficult to determine. Due to the seed-borne nature of the disease, use of healthy and certified pathogen free seeds is the most important strategy for managing this disease. The wheat bacterial mosaic has been reported in wheat fields in several provinces of Iran and it seems to be widespread in different wheat growing areas. In order to better understand the disease, its various aspects including the symptoms, pathogen biology and its host ranges, and management of the disease are reviewed in this article.

Alizadeh Aliabadi A, Faghihi MM, Salehi M, Ghasemi A (2022) Dynamics of emergence and spread of citrus huanglongbing disease in Iran. Plant Pathology Science 11(2):11-21. Doi: 10.2982/PPS.11.2.11
Introduction: Huanglongbing or Fruit Greening is one of the major citrus diseases in Iran that has spread to most of the country's citrus growing provinces. In this study, the prevalence trend of the disease in seven provinces was investigated and analyzed. Materials and Methods: Citrus orchards in Sistan-Balochestan, Hormozgan, Bushehr, Khuzestan, Fars, Kerman and Mazandaran provinces were visited and samples suspected of having this disease were collected, in 2007-2009 and 2017-2019 years. After DNA extraction from the samples, the PCR test was performed using the specific primers OI1/OI2c and A2/J5. Results: It was found that the percentage of infected specimens, infected areas and number of hosts of Candidatus Liberibacter asiaticus, the causative agent of this disease, has increased over this period. At the end of this period, some samples of oranges, tangerines, grapefruits, bitter oranges, Lisbon lemons and Mexican limes were obtained from the provinces: Kerman, Hormozgan, Sistan-Baluchestan, and Fars were infected with the disease. Conclusion: The study of the disease during these years showed that: the infected areas and the host range of the disease have expanded a lot during this period, and the spread of the disease in citrus cultivation areas in the south of the country has been with a gentle slope. The reduction of the disease-carrying psyllium population during these years seems to have been effective in slowing down the spread of the disease.

Abstract
Leaf gall and fasciation disease of ornamental flowers and some crops and vegetables, is caused by the gram-positive bacterium Rhodococcus fascians. The symptoms of the disease are leaf gall, fasciation, and witches’-broom of the branches. The disease has been reported sporadically from most of the floricultural areas of the world and is especially important in the cut flower industry. The disease was first reported in 1976 on the petunia from Iran. R. fascians has a wide host range and causes severe symptoms in some susceptible hosts. The pathogen is often spread with rain, irrigation water and during flower harvesting and is also seed-borne in some hosts. Prevention and adherence to cultural hygiene are the most important strategies for disease management. Various aspects of the disease including history, disease symptoms, pathogen characteristics, host range, disease cycle, pathogenesis mechanism, and its management are described in this article
