Abstract
Microbial diseases are a great threat to global health and cause considerable mortality and extensive economic losses each year. The medications for treating this group of diseases (antibiotics, antiviral, antifungal drugs, etc.) directly attack the pathogenic agents by recognizing the target molecules. However, it is necessary to note that excessive use of any of these drugs can lead to an increase in microbial resistance and infectious diseases. New therapeutic methods have been studied recently using emerging drugs such as mesenchymal stem cell-derived exosomes (MSC-Exos) and antimicrobial peptides (AMPs), which act based on two completely different strategies against pathogens including Host-Directed Therapy (HDT) and Pathogen-Directed Therapy (PDT), respectively. In the PDT approach, AMPs interact directly with pathogens to interrupt their intrusion, survival, and proliferation. These drugs interact directly with the cell membrane or intracellular components of pathogens and cause the death of pathogens or inhibit their replication. The mechanism of action of MSC-Exos in HDT is based on immunomodulation and regulation, promotion of tissue regeneration, and reduced host toxicity. This review studies the potential of mesenchymal stem cell-derived exosomes/ATPs therapeutic properties against microbial infectious diseases especially pulmonary infections and sepsis.

Abstract
The novel human coronavirus, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), which results in the coronavirus disease 2019 (COVID-19), has caused a serious threat to global public health. Therefore, many studies are performed on the causes and prevalence of this disease and the possible co-occurrence of the infection with other viral and bacterial pathogens is investigated. Respiratory infections predispose patients to co-infections and these lead to increased disease severity and mortality. Numerous types of antibiotics have been employed for the prevention and treatment of bacterial co-infection and secondary bacterial infections in patients with a SARS-CoV-2 infection. Although antibiotics do not directly affect SARS-CoV-2, viral respiratory infections often result in bacterial pneumonia. It is possible that some patients die from bacterial co-infection rather than virus itself. Therefore, bacterial co-infection and secondary bacterial infection are considered critical risk factors for the severity and mortality rates of COVID-19. In this review, we will summarize the bacterial co-infection and secondary bacterial infection in some featured respiratory viral infections, especially COVID-19.

Abstract
Millions of symbiotic and pathogenic microorganisms known as microbiota colonize the host body. The microbiome plays an important role in human health and colonizes hundreds of different species of multicellular organisms so that they are introduced as the metaorganisms. Changes in the microbial population of the gut microbiome may cause resistance to pathogenic bacteria-induced infection. Understanding the principles of Host-Microbiota Interactions (HMIs) is important because it clarifies our insight towards the mechanisms of infections established in the host. Interactions between the host and the microbiota help answer the question of how a microorganism can contribute to the health or disease of the host. Microbiota can increase host resistance to colonization of pathogenic species. Studying the HMIs network can in several ways delineate the pathogenic mechanisms of pathogens and thereby help to increase useful and novel therapeutic pathways. For example, the potentially unique microbial effects that target the distinct host or interfere with the endogenous host interactions can be identified. In addition, the way mutations in essential proteins in the host and/or in the microbes can influence the interactions between them may be determined. Furthermore, HMIs help in identifying host cell regulatory modules.

Abstract
In recent years, the H9N2 influenzavirus has been circulating widely in poultry farms causing extensive damage. The hemagglutinin (HA) genes of the two virus isolates of H9N2 subtype in specific pathogen-free chickens were studied to determine the shedding rate in the host’s oropharyngeal and cloacal routes and their genetic relationship. The sequence analysis and phylogenetic study of the samples were performed by comparing each isolate with other H9N2 isolates in the gene bank. In the present study, the chickens were inoculated with low pathogenic avian influenza virus (LPAIV) (A/Chicken/Iran/ZMT-101/1998 [H9N2]) through the intranasal route. Oropharyngeal and cloacal swabs were collected from the chickens within 1-10 days after inoculation. The rate of viral shedding was measured within the previous 10 days by the real-time reverse transcriptase polymerase chain reaction molecular technique. No clinical symptoms were observed during the experiment in the chickens. The results obtained from this technique showed that the main route of shedding for LPAIV was oropharyngeal areas (p <0.05). Both isolates had a similar proteolytic R-S-S-R sequence at the cleavage site of the HA gene and contained glutamine (Q) amino acid at position 226 of the HA receptor-binding site, indicating that these isolates were nonpathogenic. Phylogenetic analysis demonstrated that both isolates belonged to the Eurasian clade. The comparison of these isolates with other isolates in the gene bank showed that they had the greatest similarity with the isolates in clade 1 and the least homology with the isolates in clade 4.
