ABSTRACT
Background and Aim: The coronavirus disease-19 (COVID-19) pandemic caused global economic and health problems. The pandemic increased the number of infectious diseases categorized as neglected diseases, such as staphylococcosis, which is caused by methicillin-resistant Staphylococcus aureus (MRSA). Celery is an herb that consist of antioxidants that can potentially act as antimicrobial agents. This study aimed to analyze the efficacy of celery alcoholic extract against systemic MRSA infections in rat models. Materials and Methods: In this study, 36 male, 6-month-old Sprague-Dawley rats (average weight: 300 g) were used as models. The rats were divided into six groups: Group K- (negative control), Group K+ (infected with MRSA without therapy), Group V (infected with MRSA+100 mg vancomycin per kg body weight [BW]), Group P1 (infected with MRSA+1 mg celery extract per kg BW), Group P2 (infected with MRSA+2 mg celery extract per kg BW), and Group P4 (infected with MRSA+4 mg celery extract per kg BW). The therapy was given once daily for 7 days. Blood and organs were taken on day 7 for hematology, serology, immunohistochemistry, and histopathology. Results: Results showed that 4 mg celery extract per kg BW promotes the healing of MRSA systemic infections in rat models (p≤0.05). The better prognosis was indicated by the normalization of red blood cell indices, white blood cell, neutrophil and lymphocyte counts, Cluster of differentiation 4+, Cluster of differentiation 8+, and Cyclooxygenase-2 expression and absence of severe tissue damage. Celery extracts inhibited MRSA growth in the blood samples. Conclusion: It can be concluded that celery alcoholic extract can potentially be used as an antimicrobial agent against systemic MRSA infections. A clinical study regarding the efficacy of celery extract must be conducted to ensure its potency against MRSA infections in humans.
ABSTRACT
BACKGROUND AND AIM: The coronavirus diseases-2019 (COVID-19) pandemic has caused a global lockdown, which has limited the mobility of the public, and thus, more time is spent with their pets. Unfortunately, many social media have blamed pet animals as a reservoir of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), the etiologic agent of COVID-19, triggering a panic abandonment of pets. However, no article has summarized the information regarding the role of pets as SARS-CoV-2 reservoirs. This study aimed to evaluate the role of pets as a reservoir of SARS-CoV-2 on the basis of research papers (i.e., animal model, surveillance, and case report) published in 2020. MATERIALS AND METHODS: The review was conducted using articles from the PubMed database in 2020, using the keywords "COVID-19 in domesticated animals," which were screened and analyzed. Only the data from research articles were mimicked and transformed to conduct a meta-analysis. The meta-analysis was conducted regarding the effects of inhabitation and viral shedding in pets. In this study, we used 95% confidence intervals. RESULTS: A total of 132 papers in PubMed were related to the keywords, whereas only 12 papers were appropriate to answer the dynamics of the role of pets as the reservoir for SARS-CoV-2. Seven studies indicated the potential of cat-cat (4/7), human-cat (2/7), and human-dog (1/7) SARS-CoV-2 transmission. No study proved the presence of cat-human transmission. Another study showed that comingling did not affect SARS-CoV-2 viral shedding among a cat and dog. Furthermore, the viral shedding of cats and dogs caused asymptomatic manifestations and generated neutralizing antibodies within a short period of time. CONCLUSION: SARS-CoV-2 transmission is present in domesticated animals, especially in pet cats and dogs, and transmission occurs between animals of the same species (cat-cat). The reverse zoonosis (zooanthroponosis) was found from human to cat/dog (comingled) with asymptomatic clinical signs due to the representation of neutralizing antibodies.
