| Abstract |
Currently extended-spectrum β-lactamase (ESβL) and carbapenemase producing gram-negative bacteria are the greatest concern among the neonatal population with very limited therapeutic options. The aim of this study was to assess the prevalence of ESβL and carbapenemase producing gram-negative bacilli, associated factors and antimicrobial resistance patterns among neonates in intensive care units. An institutional-based cross-sectional study was conducted from February to June 2021 on 212 neonates in intensive care units. Risk factors data were collected by using a well-designed questionnaire. A rectal swab sample was collected using a sterile cotton swab and inoculated on MacConkey agar. Bacterial isolates were identified using various biochemical tests. ESβL and carbapenemase were first screened by indicator cephalosporins (cefotaxime (30µg) and ceftazidine (30µg)) and carbapenem (meropenem and ertapenem), respectively. ESβL and carbapenemase were confirmed by a double-disk synergy test and modified carbapenem inactivation methods, respectively. SPSS version 21.0 was used for data analysis. A P-value ≤ 0.05 was considered as statistically significant. The overall prevalence of ESβL-producing gram-negative bacilli was 72/212 (34%). The predominant ESβL-producing isolate was Klebsiella pneumoniae 23/72 (31.9%) followed by Escherichia coli 17/72 (23.6%). Five (2.4%) carbapenemase-producing gram-negative bacilli were isolated. ESβL-producing isolates showed a high resistance against ampicillin 72/72 (100%), augmentin 69/72 (95.8%) and gentamycin 57/72 (79.2%). The majority 63/72 (87.5%) of isolated ESβL-producing gram-negative bacilli were multi-drug resistant (MDR). Rectal carriage of ESβL by neonates showed a statistically significant association with endotracheal intubation (p = 0.001; AOR = 4.2; 96% CI = (1.8-9.5)), treatment with ampicillin+gentamycin (p = 0.004; AOR = 3.3; 95% CI = (1.5-7.6)) and staying in a neonatal intensive care unit (NICU) between 11 and 20 days (p = 0.042; AOR = 2; 95% CI = (1.0-4.5)). A high prevalence of ESβL-producing bacterial isolates was observed for commonly used antibiotics which needs further attention. Therefore, continuous and regular follow-ups of drug resistance patterns is important for the proper treatment and management of ESβL and carbapenemase producing gram-negative bacilli. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 October 2021.
All research outputs
#20,669,432
of 25,392,582 outputs
Outputs from Infection and Drug Resistance
#1,295
of 2,042 outputs
Outputs of similar age
#328,450
of 434,935 outputs
Outputs of similar age from Infection and Drug Resistance
#56
of 83 outputs
Altmetric has tracked 25,392,582 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,042 research outputs from this source. They receive a mean Attention Score of 4.9. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 434,935 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 83 others from the same source and published within six weeks on either side of this one. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
