    Abstract: Vibrio parahaemolyticus is one of the major foodborne pathogens owing to its cause of infectious diseases such as gastroenteritis. These diseases are often associated with the consumption of contaminated seafood. This study aims to investigate the presence of V. parahaemolyticus, their virulence, antibiotic profiles, and plasmid profiles from 77 different kinds of shellfish samples collected from wet markets and supermarkets in Selangor, Malaysia. High densities of Vibrio species ( 〉 5 log CFU/g) were found in 14/16 groups of shellfish. Among 77 presumptive V. parahaemolyticus isolates, 43 (55.8%) were positive for the toxR gene, confirming the identity of the isolates at the species level. However, none of the V. parahaemolyticus isolates harboured the virulence tdh and trh genes. The antibiotic susceptibility of the V. parahaemolyticus isolates revealed that most of them were resistant to ampicillin (95.3%), ampicillin-sulbactam (81.4%), cefotaxime (37.2%) and imipenem (23.3%). The plasmid profiles of the V. parahaemolyticus isolates showed that 41.9% (18/43) possess at least one plasmid. Our results indicate the V. parahaemolyticus isolates are continuously exposed to various antibiotics in the environments, thus consuming the seafood carries a potential health risk to consumers. The antibiotic resistance conferred by the species necessitates an immediate plan to approach the usage of antibiotics differently.

    Abstract: As the world recovers from the COVID-19 pandemic, concern remains for future potential outbreaks because of the persisting effects of climate change, including the proliferation of infectious diseases. The frequent isolation of Vibrio parahaemolyticus in the surrounding environment is of concern as it can cause infections in marine animals and transmitted to humans. V. parahaemolyticus is the leading cause of foodborne gastroenteritis worldwide. Malaysia is one of the top seafood consumers and this places us at a higher risk of exposure to V. parahaemolyticus infections. Over the years, this foodborne pathogen has been isolated from various sources in Malaysia, mainly from seafood such as shellfish, shrimps, and fish. To make matters worse, there has been an emergence of antibiotic-resistant V. parahaemolyticus worldwide, which is attributed to the uncontrolled use of antibiotics in aquaculture to prevent and treat vibriosis. Therefore, it is vital to utilize alternatives such as probiotics to control V. parahaemolyticus to prevent further propagation of antibiotic-resistant strains of the bacteria. A potential candidate for probiotics is Streptomyces sp., a class of filamentous, Gram-positive bacteria that produce a variety of bioactive compounds during their life cycle, which can be useful in drug discovery. The bioactive compounds produced by Streptomyces sp. have been proven to have microbiota-modulating and stimulatory effects on the host, enhancing immunity and providing protective effects against V. parahaemolyticus infections. With the application of Streptomyces sp. as probiotics in aquaculture, the efficacy of the available antibiotics can be preserved, and the further spread of antibiotic resistance in the environment can be reduced.

    Abstract: The COVID-19 pandemic has quickly become the most significant public health phenomenon, effectively eclipsing the H1N1 and Ebola crises that came before it. It can spread rapidly and has caused the death and disability of many worldwide. Vaccines are our most effective line of defense against the rapidly spreading and mutating virion. Still, there is significant vaccine hesitancy among those with autoimmune conditions who fear the vaccine may cause them more harm than good. This scoping review explores the safety, outcomes, and effects of COVID-19 vaccines in autoimmune patients. Online databases; Pubmed, Ovid Medline, and Scopus were used to search published literature evaluating the effectiveness and side effects of COVID-19 vaccines in patients with autoimmune conditions. The search results were limited to 4 distinct autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, psoriasis, and myasthenia gravis). Thirty-seven studies were retrieved and assessed on the safety, effects, and outcomes of COVID-19 vaccination in patients with the chosen autoimmune conditions. Overall, the risk of flares and the development of severe side effects after vaccination was low. Most autoimmune patients showed a good antibody response to vaccination, especially after the second dose. This review provides a favorable impact of vaccination in patients with autoimmune conditions.

    Abstract: Helicobacter pylori is a highly prevalent bacteria that can harm humans due to its major involvement in developing gastrointestinal diseases, particularly gastric cancer. Therefore, eradicating H. pylori is one of the most important strategies for preventing gastric cancer. Antibiotic treatment has always been the gold standard treatment for H. pylori infection. However, the decreasing efficacy of antibiotic therapy due to the rising antibiotic resistance and high incidence of dysbiosis-related adverse effects resulted in eradication failure. To enhance the effectiveness of antibiotic therapy, strategies that modulate the gut microbiome were proposed to play a positive role. Generally, the integration of probiotics or symbiotic into antibiotic therapy was shown to enhance the eradication rate and reduce the incidence of adverse effects. This review aims to discuss the role and effect of H. pylori in gastric carcinogenesis and gut microbiome modulation in eradicating H. pylori infection.

    Abstract: A novel strain, Streptomyces griseiviridis MUM 136JT was recovered from a mangrove forest soil in Malaysia. The Gram-positive bacterium forms strong yellow aerial mycelium and moderate yellow substrate mycelium on ISP 2 agar. A polyphasic approachwas used to determine the taxonomy status of strain MUM 136JT. The strain showed a spectrum of phylogenetic and chemotaxonomic properties consistent with those of the members of the genus Streptomyces. The cell wall peptidoglycan was determined to contain LL-diaminopimelic acid. The predominant menaquinones were identified as MK-9(H8) and MK-9(H6), while the identified polar lipids consisted of lipid, aminolipid, phospholipid, phosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine, diphosphatidylglycerol, and phosphatidylinositolmannoside. The cell wall sugars consist of ribose, mannose, and galactose. The predominant cellular fatty acids ( 〉 10.0 %) were identified as iso-C16:0 (31.6 %), anteiso-C15:0 (14.8 %), iso-C15:0 (12.0 %), and anteiso-C17:0 (11.1 %). Phylogenetic analysis identified that closely related strains for MUM 136JT are Streptomyces leeuwenhoekii DSM 42122T (98.9 %), Streptomyces erythrogriseus JCM 9650T (98.4 %), Streptomyces griseoincarnatus JCM 4381T (98.5 %). The DNA-DNA relatedness values between MUM 136 JT and closely related type strains ranged from 13.3 ± 1.5 % to 17.4 ± 2.0 %. The name Streptomyces griseiviridis sp. nov. is proposed, and the type strain is MUM 136JT (= NBRC 114249T = MCCC 1K04199T).

    Abstract: Colorectal cancer (CRC) remains one of the top cancers in the world. Although early detection improves the survival rate to around 90%, late detection would mean the need to use chemotherapy or radiotherapy, especially if surgery is not feasible. 5-fluorouracil (5-FU) is one of the common anti-cancer drugs used in treating CRC. It is the drug that has the greatest efficacy on CRC. Although it improves the survival rate, it has many detrimental side effects. One of these side effects is intestinal mucositis. It is described as having reduced villus height, villus atrophy, crypt fissure, abdominal discomfort, diarrhoea, and weight loss. Clinically, there is no conclusive treatment therapy for mucositis. This is possibly due to the complex mechanism of the pathobiology of intestinal mucositis that includes the production of pro-inflammatory cytokines and increased epithelial cell apoptosis. 5-FU itself is known to cause gut dysbiosis. Current studies revealed probiotics play a role in attenuating this inflammatory process of intestinal mucositis by reversing gut dysbiosis, reducing the expression of pro-inflammatory cytokines, and reducing intestinal damage. This review outlines the latest evidence supporting probiotic use in ameliorating 5-FU induced intestinal mucositis, thereby promoting good health and well-being in colorectal cancer patients receiving 5-FU chemotherapy.

    Abstract: The COVID-19 pandemic has plagued the world for over three years since discovering the causative virus, SARS-CoV-2, in China. The rampant spread of the virus led to the loss of livelihoods of millions across the globe. This public health emergency prompted the rapid development of vaccines and treatments to fight against viral infection. Vaccines against the viral infection started rolling out in late 2020, and the distribution of the vaccines worldwide managed to reduce the symptoms of COVID-19 and prevent outbreaks in local communities. However, COVID-19 infections are still prevalent, with patients suffering from severe symptoms which require oxygen support or mechanical ventilation. Thus, therapeutic agents for COVID-19 play a significant role in reducing the risk of disease progression into severe disease and improving hospitalized patients' clinical outcomes. Existing drugs such as remdesivir, molnupiravir, baricitinib, anakinra, and tocilizumab have been repurposed to treat COVID-19 earlier during the pandemic to meet the urgent demand for treatment. There are also novel antiviral and immunomodulating treatments (nirmatrelvir plus ritonavir, ensitrelvir, regdanvimab, sotrovimab, and vilobelimab) that were developed during the pandemic to fight against COVID-19 infections. These therapeutic agents have been reported to be effective and safe for use to treat COVID-19 infections of different severity. Nevertheless, continuous surveillance is imperative in ensuring that these treatment methods maintain efficacy and safety profiles in treating COVID-19 caused by different variants of the virus.

    Abstract: Skin and soft tissue infections are common presentations for non-tuberculous mycobacteria (NTM). The cutaneous infections caused by NTM may cause localized or diffuse lesions. M. ulcerans is one of the most identified pathogens that involves in the skin and soft tissue mycobacterial infections. Meanwhile, M. marinum, as an NTM has also become important emerging causal agents of cutaneous disease in various geographical regions. Although having common ancestry and highly similar in genetic makeup, M. ulcerans and M. marinum have differential impacts on the host innate immune system. In term pathogenesis, prolonged cell exposure to exotoxin mycolactone produced by M. ulcerans could lead to Buruli ulcer. Meanwhile, like most pathogenic mycobacteria, M. marinum evades the host immune responses by invading and replicating inside host cells and it is capable of modulating host immune responses. This article aims to provide a general overview and comparisons between the pathogenesis, diagnosis, prevention and therapeutic strategies for M. ulcerans and M. marinum.

    Abstract: South Africa is one of the countries heavily impacted by the COVID-19 pandemic. As of 9 January 2022, over 3.5 million confirmed cases of COVID-19 have been reported, and 93 551 deaths have been recorded in the country. The South African healthcare system faced a lack of essential resources and financial burdens by outbreaks and its new variant of concern (VOC), the Omicron. The local government has done as much as possible to control the spread of the virus in the local communities by quickly implementing lockdowns and enforcing movement restrictions. An eight-stage program to combat COVID-19 and a national vaccination strategy was also developed soon to manage the Coronavirus spread in the country better. As the country struggles to secure and administer COVID-19 vaccines to its people, the Coronavirus has been rapidly mutating and causing new waves of infections within the nation. The COVID-19 experience in South Africa demonstrates the great importance of equitable access to medicine, medical equipment, and vaccines globally. Equitable access to these essential resources is critical to prevent the virus spread across borders and reduce mortality rates worldwide.
