In several narrative and descriptive review arti-
cles reported recently, several priorities due to the
resistance towards antibiotic was well written and
discussed. Most of the antibiotic resistant-bacterial
isolates were those commonly causing the blood-
stream infections, Acinetobacter baumanii (BaiB and
HuangW, 2022). A. baumannii is an emerging bacte-
rial pathogen that provokes certain types of infectious
diseases in hospitals occurred and reported around
the world. By utilizing the available bioinformat-
ics tools, such as GenVision a component of DNAS-
TAR’s Lasergene Core Suite, the genome of A. bau-
manii isolates which consists of chromosomes and
plasmids were studied.3 A. baumanii isolates often
carry plasmids vary in size and are widespread. Many
of them are associated with the acquisition of an-
tibiotic resistance genes, which could be the reasons
for their ability to well survive in the patients under
treatment with commonly used antibiotics (Salgado-
camargo et al., 2020).
The resistance cases found in patients diagnosed
with tuberculosis (TB) is one of resistance issue that
should not be neglected. Mycobacterium tuberculo-
sis, the causative infectious agent of TB, is one of
the world’s leading killers, but there are a significant
number of antibiotics directed against tuberculosis.
This is primarily due to drug resistance mechanisms
present in bacteria leading to multidrug-resistant tu-
berculosis (MDR-TB) (BiswasSS and BorahVV, ). A
variety of computational tools are available that are
used for virtual screening of large numbers of certain
compounds, either synthetic or the plant extracts, in
order to combat the occurring resistance in this bac-
terium. However, till nowadays, there is still no re-
port reported highly successful approach for handling
this matter while the number of resistance case was
reported to continuously increase (YuwonoA et al., ).
Take the antibiotic resistance of Klebsiella pneu-
moniae, a common cause of health-care associated in-
fections known as nosocomial infections, as another
example. K. pneumoniae is one of biofilm-well form-
ing bacteria (LiY and ZhangL, 2022). The ability
of this bacterium in forming the biofilms could be
the reason of largely resistance found in isolated K.
pneumoniae isolates. The ability to form biofilms has
been shown to be highly resistant to antibiotics (LiY
and ZhangL, 2022; Panjaitan, 2019). Especially in K.
pneumoniae, the genetic information difference and
the different expression levels of certain genes in this
bacterium was reported to play an important role in
regulating its ability to form the biofilm, which surely
affects its resistance towards certain antibiotic. Et-
cABC, the novel clustered genes in an operon, was
previously reported and proposed to be the genes
regulating the biofilms formation in K. pneumoniae
STU-1 (Panjaitan, 2019). However, etcABC is not the
only genes regulating virulence factors of K. pneu-
moniae. The components of phosphoenol-pyruvate
phosphotransferase system (PTS) in K. pneumoniae
was reported also to affect the formation of bacterial
biofilms (HorngYT et al., 2018).
Many approaches had been developed and pro-
cessed by WHO worldwide. However, till nowadays,
the approach that could be utilized as a way out still
stays being a question. What approach could it be?
Although predictions are reasonably accurate, medi-
cal interventions to improve patient outcomes are of-
ten too late to be effective. To advance medical care
of our patients, this study aims to identify micro-
bial characteristics associated with poor clinical out-
comes.
2 BIONFORMATICS TOOLS
USED FOR PREDICTING AND
ADDRESSING THE
ANTIBIOTIC RESISTANCES
In recent years, the amount of molecular informa-
tion attributed to clinical data has increased signif-
icantly, thanks to the implementation of approaches
and resources that enable an ’omics’ view of dis-
eases. Bioinformatics is therefore seen as essential
for managing vast amounts of data for better diagno-
sis and treatment of rare and complex diseases. In-
deed, bioinformatics approaches are capable of find-
ing relationships between genomics, transcriptomics,
proteomics, metabolomics, interactomics, and other
’omics’ data that can elucidate complex interactions
between different levels and timescales. The tech-
niques of data mining enable the simulation of com-
plex systems and the construction of dynamic net-
works with the aim of developing predictive, preven-
tive and personalized medicine.
In order to further explore the molecular and ge-
nomic characteristics of bacterial isolates with resis-
tance towards antibacterial agents, whole-genome se-
quencing and analysis was widely utilized nowadays.
The use of next generation sequencing (NGS), a se-
quencing platform, started to be very useful for AMR
analysis (SabatAJ and AkkerboomV, 3 01). Next-
generation DNA sequencing machines are generat-
ing sequence data at unprecedented speeds, but tra-
ditional single-processor sequence alignment algo-
rithms struggle to keep up.
