Streptococcus pluranimalium, a gram-positive aerobic coccus, has been isolated primarily from several farm animals. The pathogenicity of this species is not well characterised either in animals or humans. As per the literature, cases of S. pluranimalium infection in humans have been reported only a handful of times. We report the case of cerebral abscess caused by S. pluranimalium in a patient who presented with weakness and confusion. The diagnosis of cerebral abscess was made on imaging supported by microbiological culture. Burr hole procedure for abscess drainage followed by an antibiotic regimen based on culture and sensitivity results contributed to a successful outcome. The bacteria were identified by analytical profile index for Streptococci (API Strep) and VITEK 2 gram-positive cocci panel. The case was successfully treated with vancomycin.

Introduction In Pakistan, the fourth wave of coronavirus disease 2019 (Covid-19) started around July 2021, which was dominated by the Delta variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. The vaccination drive to immunize the people of Pakistan against Covid-19 was also going on during this period. There were multiple types of vaccines being administered to the people of Pakistan, as the vaccines had been procured from multiple sources. Some people had apprehensions about different vaccines being administered in the country. The purpose of this study was to compare the clinical characteristics and outcome of the patients vaccinated against Covid-19 with those of the non-vaccinated patients during the fourth wave of Covid-19 in Pakistan Naval Ship (PNS) Shifa Hospital. Methods The cross-sectional descriptive study was performed at PNS Shifa Hospital Karachi, from July to October 2021. All the Covid-19 patients treated in PNS Shifa Hospital during the “fourth Covid-19 wave” were interviewed. Their medical records were accessed, and they were followed up till their discharge from the hospital. The vaccinated and non-vaccinated patients were compared for differences in their age or gender distribution, the severity of illness, comorbidities, and mortality. Results There were 884 participants in the study: 664 (75.11%) men and 220 (24.89%) women. There were 493 patients below 40 years of age, 233 were 40-59 years old, and 158 were aged 60 and above. One hundred and sixty-nine patients had one or more comorbidities, including hypertension, diabetes mellitus, ischemic heart disease, various malignancies, bronchial asthma, and chronic kidney disease. There were 63 (7.13%) obese patients, 28 of whom developed severe disease. Five hundred and four (57%) patients were vaccinated and 380 (47%) were non-vaccinated. Among the vaccinated patients, the effect of Covid-19 was mild in 58.37%, moderate in 36.11%, severe in 0.79%, and critical in 4.37%. Among the non-vaccinated patients, the effect of Covid-19 was mild in 40.26%, moderate in 46.58%, severe in 3.16%, and critical in 10%. The difference in disease severity between the two groups was statistically significant ( p <0.05). Conclusion Vaccinated Covid-19 patients had significantly lower severity of disease and displayed better outcomes when compared to non-vaccinated patients during the fourth Covid-19 wave dominated by the Delta variant of the SARS-CoV-2 virus.

Abstract:Background: Third generation cephalosporins are still most commonly used antibiotics empirically in our setup leading to emergence of resistance in this group. In this environment of increasing resistance, empirical use of this group of antibiotics would be a futile effort. Therefore, this study was conducted to evaluate the in vitro efficacy of fourth generation cephalosporin cefepime against multi-drug resistant isolates of Pseudomonas aeruginosa from various clinical specimens in our setup. Methodology: All the clinical specimens giving growth of Pseudomonas aeruginosa were included in the study. Modified Kirby-Bauer disk diffusion method was used for sensitivity testing. Isolates resistant to three or more than three groups of antibiotics were included in the final results. Place and Duration of Results:A total of 100 multi-drug resistant Pseudomonas aeruginosa isolates were cultured from various clinical specimens. Out of 100 isolates, 71% were resistant to cefepime while resistance rate of amikacin, gentamicin, ceftazidime, tazobactem/piperacillin, sulbactam/piperacillin, imipenem and polymyxin were 61%, 83%, 72%, 10%, 2%, 45% and 2% respectively. Conclusion:Drug resistance in Pseudomonas aeruginosa is alarming as it is now increasing even in newer generation of drugs. It is the need of hour to follow strict hospital infection control and antibiotic policies to halt the spread of this resistance.
