4%) patients had concomitant bacterial-viral infection (mixed group). Sixty-nine (64.5%) and 50 (46.7%) patient samples were positive for bacterial (bacterial and mixed groups) and viral (viral and mixed groups) detection, respectively. Streptococcus pneumonia (11.2%) and Influenza A (17, 15.9%), were the predominantly identified bacterial and viral species. The blaCTX-M (21.5%) was the predominant resistance gene detected. Twenty-four (22.4%) patients were positive for concomitant bacterial-viral infection; Staphylococcus aureus and Influenza A were the most common bacterial-viral combination identified.

Concomitant bacterial-viral infection was higher compared to previously published studies and the increased duration of mechanical ventilation was associated with increased disease severity.

Mortality of healthcare-associated Acinetobacter baumannii bacteremia can be 50-60% in intensive care units (ICUs). We aimed to determine the risk factors for 28-day mortality in patients with sepsis due to A. baumannii bacteremia during their ICU follow-up.

Demographic characteristics, disease severity scores on admission and bacteremia day (BD), resistance status, invasive interventions, and laboratory values showing the infection and severity of the BD, were compared between groups with and without mortality as a retrospective cohort study in the ICU of a tertiary hospital.

Of a total of 2411 patients, there were 192 cases of bacteremia. After applying the exclusion criteria, 39 patients were recruited for the study, 25 of whom died (mortality rate 64.1%). Higher age, Simplified Acute Physiology Score II (SAPS II) on admission and high Sequential Organ Failure Assessment Score (SOFA), Red Blood Cell Distribution Width (RDW) (p < 0.001), and C-Reactive Protein (CRP) (p = 0.002) on the BD and invasive intervention in follow-up were associated with mortality. When CRP and RDW were both positive, sensitivity was 72%, specificity was 100%, negative predictive value was 33%, and positive predictive value was 100% for the 28-day mortality after BD. Based on multivariate analysis, CRP and RDW values on the BD were independent risk factors for mortality.

It is critical to monitor SOFA, RDW, and CRP values in older ICU patients with SAPS II scores and who undergo invasive intervention in follow-up. Increases in these parameters may indicate bacteremia with high mortality due to A. baumannii.

Campylobacter jejuni is one of the most common bacterial causes of human gastroenteritis. Despite its public health importance, the virulence factors and mechanisms underlying C. ABT-199 research buy jejuni pathogenesis remain poorly understood and the relationships between these genes and the sources of the strains are not clear. We aimed to determine the virulence profiles of C. jejuni isolated from poultry and human cases of Campylobacteriosis.

A total of 50 strains of C. jejuni isolated from poultry and human cases of Campylobacteriosis were screened by polymerase chain reaction (PCR) for the presence of six pathogenic genes (flaA, iam, wlaN, cdtA, cdtB, cdtC).

A total of 40% (10/25) of the human isolates presented only one virulence marker. In contrast, 64% (16/25) of the poultry-derived strains showed four or five virulence markers. cdtA and flaA occurred more frequently in poultry-derived strains than in human strains. Ten different virulence profiles were observed among the human isolates and 11 among the poultry strains. Only four profiles were common to both sources profiles 3 (flaA, cdtA, cdtB, and cdtC), 5 (cdtA and cdtB), 7 (flaA and cdtB), and 10 (iam, flaA, cdtA, cdtB, and cdtC). The human-derived strains had a higher Shannon diversity index (1.9396) and Simpson index (0.8367), indicating a more diversified population than found in poultry (1.7742 and 0.7333, respectively).

We found variations in the genetic profiles of the circulating strains based on the isolation source and genes that are potentially pathogenic to humans were detected in poultry-derived strains.

The occurrence of methicillin-resistant Staphylococcus aureus (MRSA) in pets and their owners has increased due to the misuse and abuse of antibiotics. This study compared the prevalence of MRSA and Staphylococcus aureus strains in pets and their owners in urban and rural communities in Trinidad.

Questionnaires were administered to gather demographic and risk factor data for MRSA for human participants, and their pets. Nasal swabs were obtained from 100 pets (dogs and cats) and their human owners. For the isolation of MRSA, nasal swabs obtained were enriched and then plated on selective media. Staphylococcus aureus was identified using standard biochemical procedures. The resistance of S. aureus initially assessed detection of MRSA isolates to cefoxitin and confirmed by the PBP2a latex agglutination test. Antibiotic resistance was determined using the disc diffusion method.

The prevalence of MRSA was 6.0% (3/50) and 2.0% (1/50) in household pet animals and their owners, respectively in urban communities, while in rural communities, the prevalence was 6.0% (3/50) and 12.0% (6/50) respectively. The prevalence of S. aureus in pet owners was higher in the rural community (44.0%) compared to urban (30.0%). However, in pet animals, S. aureus was more frequently isolated from urban communities (78.0%) than rural ones (66.0%). Amongst the S. aureus isolates, 81.7% were resistant to one or more antimicrobial agents.

This study has demonstrated that living in a rural community increased the odds of MRSA colonization.

Infants are at risk of Staphylococcus aureus (S. aureus) colonization and infection. The aim of this study was to investigate S. aureus and methicillin-resistant S. aureus (MRSA) colonization among infants, including the prevalence, predictors of colonization, and antibiogram.

The study was cross-sectional, and involved infants aged less than one year recruited at the Princess Marie Louise Children's Hospital in Accra, Ghana. Sociodemographic and clinical data of the participants were gathered with a structured questionnaire. Nasal swabs were also obtained from them and bacteriologically cultured. S. aureus was confirmed with the coagulase test, and MRSA was confirmed by polymerase chain reaction (PCR) of the mecA gene. Antimicrobial susceptibility testing of S. aureus was done using the Kirby-Bauer method.

The carriage prevalence of S. aureus and MRSA were 34.9% (45/129) and 17.10% (22/129), respectively. Colonization with coagulase-negative Staphylococci (CoNS) was protective of both S. aureus (OR = 0.008; p < 0.001) and MRSA (OR = 0.052; p = 0.005) carriage. Maintenance of good hand hygiene prevented S. aureus carriage (OR = 0.16; p < 0.001). S. aureus resistance to antibiotics decreased across penicillin (96%), trimethoprim-sulfamethoxazole (61%), tetracycline (61%), erythromycin (39%), gentamicin (39%), fusidic acid (26%), rifampicin (17%), clindamycin (7%), and linezolid (0%); 68.8% S. aureus were multidrug resistant.

S. aureus and MRSA prevalence were high among the infants. Colonization with CoNS and good hand hygiene maintenance were predictive of MRSA and methicillin-sensitive S. aureus (MSSA) colonization, respectively.

High risk features including body temperature (BT) ≥ 39 °C, inactive appearance, white blood cells (WBC) ≥ 15,000 cells/mm3, or absolute band count (ABC) ≥ 1,500 cells/mm3 have low sensitivity and negative predictive value (NPV) to discriminate between bacterial and viral infections, leading to overuse of antibiotics. We aimed to determine whether procalcitonin (PCT) level ≥ 0.5 ng/mL can differentiate bacterial from viral infections.

The medical data of children aged 3 to 36 months who presented with fever without localizing signs or having initially undetermined cause of respiratory tract infection and/or non-mucus bloody diarrhea for 1 to 7 days and were hospitalized between January 2017 and December 2018 with one of the high-risk features were recorded. Children with an immunocompromised condition, who had previously received antibiotics, and/or had clinical sepsis were excluded.

Non-serious bacterial infection (SBI) and SBI (occult bacteremia) were found in 17.2% and 4.5%, respectively. The proportions of children with high-risk features were not significantly different between children with and without bacterial infection, except for absolute band count which was significantly higher in the bacterial infection group (419 cells/mm3, IQR [0, 1429]) than the non-bacterial group (76 cells/mm3, IQR [0,455]). A PCT level ≥ 0.5 ng/mL had the highest sensitivity and NPV (100%, 100%, respectively) to predict bacterial infection when compared with the other high-risk features.

Antibiotics can be safely withheld while waiting for hemoculture in acute febrile children with one of the high-risk features of bacterial infection with PCT level < 0.5 ng/mL.

COVID-19 incidence was relatively high among dentists in Iraq, reflecting the high number of cases in the community. Therefore, possible epidemiological features of COVID-19 infection were investigated among dentists in Iraqi Kurdistan Region.

A cross-sectional study has been conducted among dentists using a structured questionnaire. The questionnaire included demographic and working characteristics, self-reported COVID-19 history, and prevention practices toward SARS-CoV-2 during the pandemic. An online questionnaire was developed and spread with a snowball method among dentists.

We analyzed the responses of 83 participants (31 women and 52 men, mean age 33.8 ± 6.8 years). They had a mean of 10.6 ± 6.5 years of work experience and 20.2 ± 12.6 hours of weekly working time. In total, 46 (55.4%) of the participants reported COVID-19 infection. Only 29 (34.9%) participants always followed the hygiene rules. The most common personal precautions were mask-wearing (98.8%) and hand hygiene as a part of institutional protective precaution (51.8%). Of the infected dentists, 24 (52.2%) did not know the source of infection. Of the remaining 16 (34.8%) were infected from family and/or friends circle, and five (10.9%) from patients. Eleven of them (23.9%) reported transmitting the infection to at least one person. In the multivariate analyses, working in Sulaymaniyah Province (p = 0.031) and working only in a public hospital (p = 0.029) were significant risk factors for COVID-19 infection.

The high risk of COVID-19 infection among dentists in the Iraqi Kurdistan Region relates to their family and friends rather than their occupation.
