A total of 285 urine specimens were collected from pregnant women during the study period. Table 1 lists the majority of urine specimens collected from patients aged 23–27 years (41.05%), patients residing in urban areas (74.74%), subjects with a secondary certificate (35.44%), and participants with gravity between 1–2 (49.12%).
The present study reported an UTI prevalence rate of UTI among pregnant women. This outcome is slightly similar to that of a study conducted in Sana’a, Yemen, which showed that UTI occurred in 24.3% of pregnant women (31). In contrast, this finding is lower than that reported in various locations in Yemen, including 30.0% in Al-Mukalla (32) and 54.5% in Hodeidah (33). Additionally, this finding is higher than the 18% reported among pregnant women visiting hospitals in Al-Mukalla city (34). The significant differ in frequency rates may result from variations in geographical areas, populations being studied, size of samples, sanitary settings, socioeconomic status, and the diagnostic techniques implemented for the participants (35–42).
In the present finding, the highest frequency of bacteriuria in pregnant women was found among the age group 33–38 years (41.38%), followed by 18–22 years (27.08%), the age group 28–32 years (19.66%), and the age group 28–32 years (18.68%), with no statistical significance between the age group and UTIs (P > 0.05). The study by Al-Haddad (32) demonstrated analogous findings, revealing that young women are more susceptible to urinary tract infections (UTIs) than older women, with a notable prevalence of UTIs among pregnant women aged 15–24 years, constituting 53.7%. AL-Kadassy (33) reported a 69% prevalence of UTIs among those aged 20 to 29 years. A study conducted by Rohini et al (43) in India revealed that a high prevalence of bacteriuria was prevalent among individuals aged 25 to 30 years. Ghaima et al. (12) noted that the age group of 21–30 years exhibited the highest infection rate at 55%.
Furthermore, the pregnant women coming from rural areas had the highest rate of bacteriuria compared to pregnant women coming from urban areas (25.0% vs. 22.1%). This is similar to the results of a recent investigation (44–48). Previous studies conducted in Yemen revealed a higher prevalence of diseases among participants living in rural areas compared to those from urban areas. This may be attributed to the fact that most rural areas in Yemen lack access to health care centers, lack clean water, have low levels of education, particularly among females, have low income rates, lack job opportunities, and are experiencing increasing poverty rates. Therefore, the majority of people from rural areas travel to cities to seek diagnosis and receive appropriate treatment in health care centers (49–58).
The current work showed that a higher rate of bacteriuria was recorded among pregnant women with an educational level of primary school (37.04%), followed by those with an illiterate educational level (24.47%), among those with secondary schools (19.8%), and those with a college certificate (19.05%). A comparable study conducted by AL-Kadassy (33) found that the frequency of bacteriuria among pregnant women employed as teachers was 83%. Furthermore, Fatima et al. (59) found that 61.33% of pregnant women with secondary school education exhibited bacteriuria. Patients with UTIs often reside in areas that are poorly developed with inadequate access to clean water, substandard sanitation, insufficient personal hygiene, and low levels of literacy among individuals (59).
Education has been recognized as an important social aspect of health. A significant correlation between educational level and health has been observed. The impact of education is to enhance overall self-awareness regarding personal health and improve availability to health care. People with higher education levels exhibit improved health, reflected by reduced death, morbidity, and disability rates (60).
In addition, it was found that the high prevalence of bacterial UTI was 29.29% among women with 1–2 gravid compared to the low frequency (16.19%) among multigravida of 3–4, with no statistical association between the bacterial UTI and gravidity status (P > 0.05). Mohammad (61) reported similar reports, indicating that the majority of pregnant women with urinary tract infections were primigravidas, and no significant differences were observed between infected and non-infected women. Ranjan et al. (62) observed that primigravidas had the highest incidence at 60%, while multigravidas had the lowest incidence at 19%. Additionally, numerous studies indicate that multigravida women exhibit a heightened chance of having bacteriuria during pregnancy (62–63).
The recent findings indicate that the most commonly isolated bacteria were E. coli (41.56%), S. aureus (24.68%), Klebsiella sp. (15.58%), Pseudomonas aeruginosa 8 (10.39%), and Coagulase-negative Staphylococcus (CoNS) (7.79%). Other parts of Yemen have reported similar studies identifying E. coli and Staphylococci as the primary pathogens causing UTI. Al-Haddad (32) identified E. coli as the most commonly isolated bacterium at 41.5%, followed by S. aureus at 19.5%. AL-Kadassy et al. (33) identified E. coli as the most commonly isolated organism at 50.0%, followed by S. aureus at 13.3%. According to a study by Bin Hameed et al. (34), Enterobacter species, coNS, S. aureus, P. aeruginosa, S. saprophyticus, and Klebsiella pneumoniae were the pathogens that were most often isolated.
Furthermore, experts consider these bacteria to be human opportunistic pathogens and etiologic agents of nosocomial infections. Moreover, the abdomen distension makes anal cleaning more difficult (64). Bacterial contamination, where the urethra is closer to the anus in females, is one of the main causes of infections during pregnancy. E. coli is also thought to be a major uropathogen because it has several virulence factors that make it easy for it to colonize and invade the urinary epithelium, such as P and S fimbrial adhesins (65).
The present study revealed that E. coli exhibited resistance to erythromycin (78.13%), nitrofurantoin (46.88%), and lower resistance to ampicillin (21.9%) and cefepime (18.8%). Moreover, S. aureus exhibited resistance to vancomycin (73.7%), erythromycin (63.16%), and ampicillin (42.1%). In addition, P. aeruginosa was less resistant to nitrofurantoin, cefepime, and ampicillin. Prior reports indicated a significant prevalence of antimicrobial-resistant bacteria in certain regions of Yemen, attributed to the accessibility of antibiotics as over-the-counter medications, allowing unrestricted purchase without a physician's prescription, alongside issues related to the quality of antibiotics and improper drug usage. Furthermore, the majority of physicians prescribe antibiotics to patients without consulting antimicrobial susceptibility data, nor do they advise them to undergo antimicrobial susceptibility testing (67–76).
