The COVID-19 Pandemic and the Incidence of the Non-COVID-19 Pneumonia in Adults

Introduction: The coronavirus disease 2019 (COVID-19) lockdown strategies were associated with a significant decrease in the common respiratory viral diseases and decreased the need for hospitalization among children in the COVID-19 outbreak. However, the trend of non-COVID-19 pneumonia in adult people remains uncertain. Our aim is to assess the impact of the COVID-19 pandemic on the incidence of the non-COVID-19 pneumonia in adult people and understand whether the substantial decrease in pneumonia cases is the same as the decline in the incidence of respiratory viral disease activity.Methods: We conducted a retrospective analysis of adult patients presenting with pneumonia from January 2019 to December 2020. Details on all the demographics of the patient of pneumonia, hospital course details, prior admission history within 3 months, respiratory culture, and antibiotics sensitivity test were also obtained.Results: The number of adult patients with community-acquired pneumonia in 2020 was lower than that in 2019, which decreased by 74 patients in 2020. The decreasing number of patients with community-acquired pneumonia between 2019 and 2020 was from −13.9% in January to March 2020 to −39.7% in October to December 2020. The decreasing number of patients with community-acquired pneumonia between 2019 and 2020 was from −14.8% in the youngest cohort to −28.7% in those aged ≥85 years. The number of reduced patients with community-acquired pneumonia is greater in late seasons and older age, respectively. The number of adult patients with hospital-acquired pneumonia in 2020 was lower than that in 2019, which decreased by 23 patients in 2020. The decreasing number of patients with hospital-acquired pneumonia between 2019 and 2020 was from −20.0% in January to March 2020 to −52.4% in October to December 2020. The decreasing number of patients with hospital-acquired pneumonia between 2019 and 2020 was from 0% in the youngest cohort to −45.6% in those aged ≥ 85 years. The number of reduced patients with hospital-acquired pneumonia is greater in late seasons and older age, respectively.Conclusion: Interventions applied to control the COVID-19 pandemic were effective not only in substantial changes in the seasonal influenza activity, but also in decreasing adult pneumonia cases.

The profile of microorganisms that associate with acute tonsillitis in children and their antibiotics sensitivity pattern in Nigeria

Acute tonsillitis remains one of the common childhood diseases in developing countries. Prompt and appropriate treatment based on the knowledge of the causative microbiota and their antimicrobial susceptibility pattern will improve the treatment outcome and reduce time and resources spent on treatment. This study aims to determine the pattern of microbiota isolates and their susceptibility pattern. The study was a combination of the retrospective and cross-sectional method. The medical records of children treated for tonsillitis were retrieved, as well as those of children who presented with acute tonsillitis for the study. Interviewer-administered questionnaire was used to collect data, as well as document information retrieved from their medical record: presenting symptoms, treatments received. Swab sample was taken for culture and antibiotic susceptibility test. Out of the 72 swab cultures, 29 (40.3%) yielded insignificant growth of gram positive cocci. A total of nine (9) different isolates were obtained from all the significant swab cultures. Streptococcus species (13, 18.6%) and staphylococcus species (11, 15.3%) were the commonest isolates. Imipenem and levofloxacin revealed high level of susceptibility, while Ampicillin and Cefexine recorded high resistance rates. The proportion of the cultures that were positive of significant growth, the proportion of these positive isolates that were Streptococcus spp. and varied sensitivity pattern obtained underpinned the importance to advocate for culture isolates and susceptibility pattern guided treatment. These will not only an efficient approach to management of acute tonsillitis, but also a strong approach towards effective implementation of antibiotic stewardship.

Isolation, Identification and Characterization of Urinary Tract Infectious Bacteria and the Effect of Different Antibiotics

Etiological patterns of uropathogens is different in different regions due to continuous evolution, of bacteria, antibiotics sensitivity patterns, misuse and overuse of antibiotics. Therefore, it is important to know the antibiotic susceptibility patterns for prescription of suitable antibiotic. This study was conducted to determine the prevalence of uropathogens and their antimicrobial sensitivity pattern from Kohat region of Pakistan. In this study 100 samples were collected from both males and females of all ages in which 70 samples contained microbes. In 30 samples no microbial growth was recorded. The Percentage of positive culture from both male and female were 57% and 43% respectively Both Gram (+) and Gram (-) bacteria were found in UTI but E.coli (34.21%) was predominant followed by K. pneumoniae (10.52%), P. aeruginosa (9.21%), K. oxytoca (6.57%), C. albicans (5.26%), E. faecium (5.26%), E. faecalis (3.94%), S. aureus (3.94%), E. cloacea (2.63%), C. freundii (2.63%), P. mirabalis (2.63%) and A. baumannii (1.31%). Many of the isolates showed resistance to commonly used antibiotics. The sensitivity percentage of different commonly used antibiotics against both Gram (+) and Gram(-) bacteria were Ampicillin 13%, Ceftriaxone 25%, Amikacin 77%, Gentamicin 41%, Augmentin 44.77%, Fosfomycin 64%, Cotrimoxazole 36%, Nitrofurantoin 68%, Ciprofloxacin 37%, Imipenem 78%, Meropenem 67%, Cefepime 25% and Tetracycline 40%. The most effective antibiotics against both Gram (+) and Gram (-) bacteria were Fosfomycin, Imipenem, Meropenem Amikacin and Nitrofurantoin. In light of the findings of this study, it is strongly recommended to discover new antimicrobial compounds and evaluate the resistant pattern at genomic and proteomics level to discover the genes which are responsible for antibiotics resistant pattern.

Molecular Characterization Identifies Upstream Presence of ISAba1 to OXA Carbapenemase Genes in Carbapenem-Resistant Acinetobacter baumannii Isolated from a Tertiary Care Hospital in Western Maharashtra

Background Evaluating the expression pattern of oxacillinases (OXA) carbapenemases is essential to understand the prevalence and spread of carbapenem resistance Acinetobacter baumannii. Objectives The aim of the study is to evaluate the presence of OXA carbapenemase genes and ISAba1 upstream to these genes in carbapenem-resistant A. baumannii clinical isolates. Material and Methods A. baumannii isolated from clinical samples were phenotypically identified and antibiotics sensitivity was performed. Multiplex polymerase chain reaction (PCR) was used to detect OXA51-like gene, OXA carbapenemases genes (OXA-23-like, OXA-24-like, and OXA-58-like), and ISAba1 in carbapenem-resistant isolates. Results Out of 55 Acinetobacter isolates, 54 were confirmed as A. baumannii by PCR. Bla OXA-23-like gene was observed in 51 isolates of A. baumannii and none of the isolates showed the presence of bla OXA-24-like and bla OXA-58-like genes. Presence of ISAba1 upstream to OXA-23-like gene, OXA-51-like gene, and both OXA-51-like/OXA-23-like genes was observed in 51, 7, and 4 A. baumannii isolates, respectively. Conclusion The genetic pattern of carbapenem-resistant A. baumannii isolated in this study was unique, which should be factored for clinical protocols to manage infections caused by emerging resistant strains of A. baumannii.

Retail chicken meats as potential sources of Clostridioides difficile in Al-Jouf, Saudi Arabia

Introduction: Presence of Clostridioides difficile in stool of food birds and animals is a risk for contamination of their meats to become potential sources of human infection. The main virulence factors of C. difficile are its resistance to antibiotics, production of toxins and spores. As far as I know, this is the first study to evaluate C. difficile prevalence in chicken meats, its toxigenic activities and antibiotics sensitivity patterns in Al-Jouf, Saudi Arabia. Methodology: Totally, 250 raw chicken meat samples were examined. Standard microbiological and biochemical procedures were used for C. difficile isolation and identification. The suspected colonies were tested by L-proline and C. difficile test kits then confirmed by Vitek 2 compact system. Xpect C. difficile toxin A/B test was used to detect A/B toxins production. Antibiotics susceptibility patterns were detected by Epsilon tests. Results: C. difficile was isolated from 11/250 (4.40%) chicken meat samples; 5/65 (7.69%) legs, 3/65 (4.61%) thighs, 2/60 (3.33%) wings and 1/60 (1.67%) breasts (p = 0.4). All isolates were non-toxigenic. Although all isolates were vancomycin sensitive, some isolates were intermediate/resistant to metronidazole, tetracycline, clindamycin or moxifloxacin antibiotics with variable degrees. Conclusions: C. difficile might contaminate retail chicken meats. Although low level of contamination by non-toxigenic strains was detected, chicken meats should be investigated as C. difficile infection sources for humans especially elders, immune-compromised and long terms wide spectrum antibiotics-used persons. Decreased sensitivity of C. difficile to antibiotics is emerging.

Studies on the Prevalence and Etiology of Pelvic Inflammatory Disease Among Women Attending Primary Health Centers in Sokoto Metropolis

Pelvic Inflammatory Disease (PID) is an inflammation of the uterus, fallopian tube, and ovaries as it progresses to scar leading to infertility and other reproductive problems. This research work was conducted to determine the etiology, antibiogram and prevalence of pelvic inflammatory disease among women attending Public Health Centres in Sokoto metropolis. The main objective of the study is to isolate the pathogens and determine the antibiotics sensitivity pattern and prevalence age of the Disease among the patients diagnosed with PID. 155 PID patients that were sorted by age and month were diagnosed within the year 2020. Laboratory assay on the etiology and antibiogram were carried out. From the total (155) patients diagnosed with PID in this study, thirty-three (33) were within the age of 15-20, forty-one (41) were between the ages of 21-25 and fifty-five (55) were between the age ranges of 26-30. The least (26) were between ages of 36 and 40. The highest prevalence age (35.5%) in this study were observed to fall between the ages of 26-30 then followed by forty-one patients (26.5%) prevalence that were between the ages of 21-25. The least in occurrence were 26 patients (8.4%) that were between the age range of 36 and 40. Similarly, the results obtained from this study revealed that there were 77 (49.67%) recorded in the first quarter of the year 2020. This was then followed by 48 (30.97%) patients in the last quarter. The least occurrence of PID patients 30 (19.35%) were diagnosed in the second quarter of the same year. The pathogens consistently identified to be associated with the disease were Neisseria gonorrhea and ciprofloxacin was the most sensitive on antibiogram. The factors responsible were poor personal hygiene, environmental pollution and unsanitary conditions of the toilets. It is recommended that patients should regularly visit health facilities for routine diagnosis of PID and ciprofloxacin and Broad spectrum antibiotics were the most efficacious for use in this study in the treatment of Pelvic inflammatory Disease.

The Shift of Bacterial Sensitivity with Antibiotics in Acute Tonsillitis

Background: The infection of tonsil may occur primarily or secondarily as a result of upper respiratory tract infection, usually preceded by a viral infection. Bacterial tonsillitis is most commonly caused by Streptococcus pyogenes. Penicillin remains the treatment of choice for S. pyogenes tonsillitis. The present study aimed to identify the bacterial pathogen in acute tonsillitis and their sensitivity to antibiotics. Material and Methods: This prospective study was conducted in the Department of Otolaryngology and Head & Neck Surgery and Department of Microbiology, Gandaki Medical College, Pokhara Nepal from January 2018 to January 2019. Ninety-six patients who presented with acute tonsillitis and admitted in the hospital were included in the study. Results: The commonest age group of acute tonsillitis was found to be between 21-30 years. S. pyogenes was the commonest isolate 32(33.3%) followed by S. aureus 19(19.8%). Streptococcus pyogenes was sensitive to Ampicillin (65.6%) and Cloxacillin (68.7%) while the isolates were more sensitive to levofloxacin and doxycycline. Carbapenem were found to be most effective drugs for intravenous treatment. Conclusion: The most common bacterial isolates were Streptococcus pyogenes. The sensitivity of organism shift from ampicillin group to fluroquinolones and tetracycline. Identification of bacterial isolates and their antibiotics sensitivity patterns could prevent resistance of bacteria to drugs and help in the proper management of acute tonsillitis.
