Carbapenem-resistant Acinetobacter baumannii is a major health problem worldwide, especially in intensive care units (ICUs). This study aimed to detect the prevalence of A. colonization gastrointestinal tract patients admitted ICU two hospitals Saudi Arabia. In addition, it characterize molecular mechanisms carbapenem resistance these isolates. From January June 2014, 565 rectal swab specimens were screened for Acinetobacer strains and using CHROMagar KPC agar plates, respectively. Organism...

Non-O1, non-O139 Vibrio cholerae (NOVC) extraintestinal infections are rare, but recently, several clinical incidents have been reported worldwide. Toxigenic V. is a well-known etiological agent of cholera, responsible for acute dehydrating watery diarrhea. Outbreaks occur in an epidemic seasonal pattern, particularly countries with poverty and poor sanitation. Strains NOVC usually not involved causing the or pandemic outbreaks seen potential strains serogroup O1 O139. However, they can...

Monkeypox is a rare disease which rising nowadays in different countries since the first case UK was diagnosed on May 6, 2022, by United Kingdom (UK) Health Security Agency. Then more than 12,500 cases were identified over 68 up to July 18, 2022. In endemic areas, monkeypox virus (MPXV) commonly transmitted through zoonosis, while non-endemic regions, it spread human-to-human transmission. Symptoms can include flu-like symptoms, rash, or sores hands, feet, genitalia, anus. addition, people...

Transfusion-transmissible hepatitis B virus (HBV) infection is a major problem worldwide. Recently, confirmatory nucleic acid tests (NATs) for HBV DNA have been employed in several countries. We assessed the prevalence and yearly trends of blood donors Eastern Province Saudi Arabia, screening surface antigen (HBsAg), antibody against core (anti-HBc), DNA.Between 2011 2015, total 22,842 were screenedfor HBsAg, anti-HBc, using HBsAg Qualitative II kit (Abbott, Ireland Diagnostics Division,...

Abstract Vibrio parahaemolyticus belongs to the halophilic genus of Vibrionaceae family that inhabits coastal and marine environments is a major food-borne pathogen. In Gulf Cooperation Council (GCC) countries Saudi Arabia in particular, there lack information regarding detection pandemic clone or serovariants V. clones. Here, 400 seawater samples were collected examined for presence from 10 locations along coast Eastern Province Arabia. The recovered isolates serotyped, studied...

To investigate presence of Enteroaggregative Escherichia coli (EAEC) in patients suffering with diarrhea by targeting the pCVD432 (pAA) gene using PCR. There were 63 non-duplicate isolates E. isolated from diarrheal cases teaching hospital Eastern Province Saudi Arabia between May 2013 to July 2014. All strains examined for antibiotic susceptibility testing and polymerase chain reaction (PCR) detection virulence markers EAEC. Of E that reported cases, 35 (55.6%) EAEC tested positive aggR was...

Bloodstream infections (BSI) among patients with hematological malignancies (HM) could predispose them to higher morbidity and mortality for various underlying conditions. Several microorganisms, either pathogenic or opportunistic normal human flora, cause severe bacteremia septicemia. While conventional methods have their own limitations, molecular such as next-generation sequencing (NGS) can detect these blood more reliability, specificity, sensitivity, in addition information on microbial...

Abstract Shiga toxin-producing Escherichia coli (STEC) and E. O157:H7 are responsible for a wide range of foodborne outbreaks worldwide. Both O157 non-O157 causing life-threatening complications, such as hemolytic colitis uremic syndrome, which can result in kidney failure. This study was conducted to determine the presence both STEC imported frozen beef marketed Eastern Province Saudi Arabia using immunomagnetic beads (IMB), CHROMagr medium, multiplex-PCR.

Shiga toxin-producing Escherichia coli (STEC), particularly E. O157:H7, is a major contributor to foodborne outbreaks globally. Both O157 and non-O157 strains can lead severe health issues, including hemolytic colitis uremic syndrome, which result in kidney failure. Two hundred one frozen beef samples were purchased from various supermarkets located the Eastern Province of Saudi Arabia subsequently enriched tryptic soy broth (TSB). From TSB, 1 mL portion was mixed with immunomagnetic beads...
