ABSTRACT
ABSTRACT Background: There is scarce information about the occurrence of extended-spectrum β-lactamases (ESBLs) in Salmonella enterica serovar Typhi (S. Typhi) from patients with typhoid fever. Objective: To study the antimicrobial resistance and ESBL encoding genes among S. Typhi isolates in aforesaid patients from Lagos, Nigeria. Methods: S. Typhi isolates were collected from blood samples of typhoid fever patients from 4 academic medical centers in Lagos, Nigeria. The identification of isolates and their antibiotic susceptibility testing were performed by standard bacteriological techniques and disc diffusion method, respectively. The production of ESBLs was investigated using combination disk test (CDT) and polymerase chain reaction (PCR). Results: A total of 27 S. Typhi isolates was collected. All isolates were susceptible to imipenem and nitrofurantoin. Fifteen (55.6%) isolates were multidrug-resistant (MDR). The CDT test showed 11 (40.7%) ESBL producer isolates. However, the PCR revealed a higher occurrence rate for ESBL producers (66.7%, n = 18/27). The ESBL genes were as follows: blaCTX-M (37.0%, n = 10/27), blaSHV (18.5%, n = 5/27), and blaTEM (44.4%, n = 12/27). All ESBL positive S. Typhi isolates were MDR. Conclusions: This study showed the emergence of ESBL-harboring S. Typhi in patients with typhoid fever from Nigeria.
ABSTRACT
Background: The objective was to study the extent of infertility knowledge, attitude and care seeking behavioral pattern of infertile men in Lagos.Methods: A cross sectional study was carried out using questionnaire between 2009 and 2014. Adult males who were clinically infertile, visiting the clinics for the first time and consented were studied. Descriptive statistics were used for the analysis.Results: Only 226 men, mean age 38±5.8 years participated. Up to 20.8% had sired a child for between >1 but <2, 20.4% for 2-5 and 58.8% for ≥6 years. Couples had coitus for once and >3 times (mean coitus 2.3±0.9 times) weekly. Only 11.1% knew about male-female factor infertility. Up to 42.9% knew about fertility and the sign of female ovulation and 38.1% correctly defined clinical infertility. Up to 40.3% switched treatment for competency of the new places and exorbitant price by 22.1%. Sixty-six (29.2%) made the first visit to a proper care place within a period >1 but <2 years, 45.1% within 2-3 years and 25.7% waited for >3 years. Majority (50 %) sought to know the causes of infertility, 14.6% how to improve fertility and 6.6% the reality of male infertility.Conclusions: Majority of the participants sought inappropriate help and delayed in seeking appropriate care. Poor collaboration and referral system observed. There is need for edification of both care providers and seekers to be ethical in their actions. Infertility care cost intervention is needed.
