    Journal of Tropical Medicine, 2025
    Diverse virulence genes encode for the Type III secretion system (T3SS) in bacteria. In Salmonella, these genes are located in the Salmonella pathogenicity Islands 1 and 2 (SPI‐1 and SPI‐2), and they facilitate bacterial invasion and replication within macrophages, contributing to the burden of nontyphoidal Salmonella infections. In this study, we investigated the prevalence of selected virulence‐encoding genes in 30 laboratory stocks of Salmonella enterica serovar Enteritidis from Nigeria (16 isolates) and nonclinical sources comprising poultry and seafood from India (14 isolates). Analysis of PCR amplicons revealed that the genes sseB, sseD, sseF, sseT, and invH were conserved in all the isolates except for two isolates obtained from clams, which did not have the sseD and sseF genes. In addition, the sseC and sseG genes were absent from all the tested isolates. This study provides insights into the distribution of selected T3SS genes among Salmonella spp. isolated from clinical and raw animal food sources in Nigeria and India, respectively.
  • Prevalence of multi-drug resistant tuberculosis among tuberculosis patients attending chest clinics in Osun-state, Nigeria
    Gbadebo J. Oyedeji, Charles Adeyemo, Affolabi Dissou, Tope Abiodun, Oyebode A.T. Alli, et al.
    Current Pharmaceutical Biotechnology, 2020
    Background: The development of multidrug-resistant tuberculosis (MDR-TB) poses a considerable threat to tuberculosis control programmes in Nigeria. There is an increase in the prevalence of MDR-TB worldwide both among new tuberculosis cases as well as previously-treated ones. There is also a rise in transmission of resistant strains due to an increase in MDR-TB patients largely due to the poor drug compliance and the impact of Human immunodeficiency virus infection. Therefore, we intend to determine the extent of MDR-TB among attendees of chest clinics in Osun-State, Nigeria. Objectives: The objective of this study was to determine the prevalence of MDR-TB among confirmed tuberculosis patients attending chest clinics in Osun-State, Nigeria. Methods: This study was conducted among 207 attendees of chest clinics in Osun-State between June, 2015 and October 15, 2016. Sputum and blood samples of the participants were collected. GeneXpert test was carried out first on the samples for simultaneous identification of MTB and rifampicin resistance. Sputum samples were cultured on Lowenstein-Jensen (L-J) medium using N-acetyl-Lcysteine- sodium hydroxide (NALC-NaOH) decontamination method. Drug susceptibility testing (DST) to three first-line drugs was carried out using the proportion DST method. Results: The prevalence of MTB was found to be 27.5% while the prevalence of MDR-TB from the fifty-seven isolates was 10.5%. Previously treated and new cases had a prevalence of 7.0% and 3.5% MDR-TB, respectively. Seventy (33.8%) participants were positive for HIV infection, out of which twenty-six (12.6%) had co-infection of tuberculosis and HIV. The mono-resistance rates of the three first-line drugs used were: 5.3% and 8.7% for ethambutol (EMB) and isoniazid (INH), respectively. No isolate had mono-resistance (0%) to rifampicin (RIF). Conclusion: This study observed the prevalence of 27.5% MTB and a prevalence of 10.5% MDR-TB among the MTB isolates. The prevalence of TB is high in Osun State. MDR-TB prevalence is higher compared with the national estimate of MDR-TB (5.1%) of 2017. Resistant TB is a threat to national tuberculosis control and it is recommended that all the facilities be equipped to cater to its diagnosis.
  • Molecular characterization of antimicrobial multi-drug resistance in non-typhoidal Salmonellae from chicken and clam in Mangalore, India

    Journal of Biomedical Research, 2018
    Salmonella enterica has been documented as one of the leading causes of salmonellosis throughout the world and is most commonly associated with the consumption of contaminated food products. Thus, this research was aimed at studying the antimicrobial susceptibility pattern and detection of quinolone resistance in Salmonella spp isolated from food of animal origin. Thirty-six Salmonella isolates comprising 8 from poultry and 28 from seafood (clams) were identified, serotyped and characterized for their antimicrobial susceptibility against 10 different antibiotics. Plasmid DNA was isolated from all the isolates by alkaline lysis, quinolone resistant non-typhoidal S. Weltevreden were examined for mutation in the DNA gyrase coding gene. Among the 36 Salmonella isolates, 20 were S. weltevreden (8 from poultry and 12 from seafood) and 16 were S. Typhimurium (from seafood). All the isolates showed multiple resistance to nalidixic acid, tetracycline, co-trimoxazole and nitrofurantoin, but, interestingly, the isolates were 100% susceptible to ampicillin, chloramphenicol and gentamicin. Resistant isolates from the study carried the genes responsible for resistance to respective antibiotics. The strain S130 isolated in the study showed single point mutation, Asp87Gly, at position 87 in quinolone resistance determining region. It revealed mutation in quinolone resistance determining region as a cause for quinolone resistance in non-typhoidal Salmonellae. The occurrence of genes accountable for plasmid mediated resistance to quinolones (viz., qnrA, qnrB and qnrS) in plasmid of non-typhoidal Salmonellae isolates provides evidence for plasmid mediated quinolone resistance.

  • Isolation and antifungal sensitivity to Candida isolates in young females

    Central European Journal of Medicine, 2011
    A survey of 104 sexually active young females tested on on cervico-vaginal swabs showed that 26 of the females (25%) had vulvovaginal candidiasis with a species distribution of Candida isolates accounting for 13 (50%) with C. albicans, 6 (23%) with C. glabrata, 1 (4%) with C. krusei, and 6 (23%) with C. tropicalis. Of the 26 (25 %) subjects that were positive for VVC, 8 (7.8 %) were symptomatic and 18 (18.8 %) were asymptomatic. However, distribution among different age groups revealed an increase in the 23–27 age group. The comparative analysis of sensitivity of the given fungi to the number of antimycotic preparations used revealed the following: in fluconazole, 2 (7.8%) isolates were sensitive, 5 (19.2%) were susceptible and dose dependent, and 19 (73%) were resistant. For voriconazole, 4 (18.4%) isolates were sensitive, 6 (23.1%) were susceptible and dose dependent, and 16 (61.5%) were resistant. For nystatin, 5 (19.2%) isolates were sensitive, 10 (38.5%) were susceptible and dose dependent, and 11 (42.3%) were resistant. It appears that Candida isolates have a variable resistance response, but 19 (73%) had maximum resistance of the isolated fungi of the genus Candida to fluconazole. Therefore, further studies on the evaluation of combination therapy should be considered for a better outcome in treatment of vulvovaginal candidiasis.
  • Detection of Arcobacter in feces of healthy chickens in Osogbo, Nigeria
    Y.O. Adesiji, A.O. Coker, J.K. Oloke
    Journal of Food Protection, 2011
    Isolation of arcobacters in foods, with the highest prevalence reported in poultry, has underscored its importance as a potential food safety problem in recent years. To estimate its prevalence in live birds, fresh stool samples from healthy chickens were screened by enrichment and plating on Arcobacter selective medium containing cefoperazone, amphotericin B, and teicoplanin. Of 150 fecal samples, only 2 (1.3%) yielded Arcobacter. Species were identified with fluorescence resonance energy transfer PCR. Isolate no. 21 from a local flock shared 99% identity with the complete genome of A. butzleri RM4018 (CP000361.1). Isolate no. 4 from a layer hen shared 100% identity with a partial 16S rRNA gene sequence of A. cryaerophilus (EF064151.1). The low prevalence of Arcobacter in the fecal samples of healthy chickens concurs with earlier studies suggesting that Arcobacter appears to be a transient colonizer of poultry intestines and therefore might not be the major source of chicken carcass contamination.
  • Faecal shedding of Arcobacter species following experimental infection in rats: Public health implications
    Yemisi Adesiji
    Central European Journal of Medicine, 2010
    Arcobacter spp. are emerging food borne pathogens associated with prolonged diarrhea and occasional systemic infections such as bactereamia and peritonitis in humans. Information on faecal shedding patterns to assess the potential role they play within the intestine however, is lacking. This study was designed to investigate faecal shedding of local isolates of Arcobacter spp. Using real time PCR for confirmation, A. cryaerophilus and A. butzleri were isolated from the stool of healthy chickens. Pathogenicity of the organisms was tested by administering a single oral challenge of 102–109 cfu/ml to 45 healthy adult male albino rats divided equally among 5 groups. Uninfected rats were used as the control group. A. cryaerophilus and A. butzleri produced infection in 100% of the animals. Experimental infection was dose dependent and caused diarrheal illness and faecal shedding was noted up to 5 weeks post infection. The present study demonstrates that rats can act as a reservoir and potential source of Arcobacter infection in humans and animals exposed to this pathogen.
