Drug Susceptibility of Trichomonas vaginalis to Metronidazole in Bushehr City (In Vitro)
نویسندگان
چکیده مقاله:
Background: Trichomoniasis is the most common non-viral sexually transmitted disease caused by the protozoan parasite Trichomonas vaginalis. Metronidazole (MTZ), a 5-nitroimidazole derivative, is the main antitrichomonal agent of choice for the treatment of trichomoniasis. Since 1962, some cases of treatment failure with metronidazole have been reported, and the increased resistance of the parasite to MTZ has emerged as a highly problematic public health issue. This study aimed to determine the current susceptibility of isolates of T. vaginalis to metronidazole in Bushehr city. Materials and Methods: This study was performed on 20 T. vaginalis isolates collected from comprehensive health service centers and hospitals in Bushehr city. After the culture of the parasites, susceptibility testing was carried out using serial twofold dilutions of MTZ (2 to 64 μg/ml). The minimum inhibitory concentration (MIC) and the minimum lethal concentration (MLC) of the trichomonads were determined after 24 and 48 h of incubation at 36 °C. Drug susceptibility assays of all the isolates were carried out twice in triplicate under aerobic and anaerobic conditions. Results: One hundred percent of the T. vaginalis isolates (20/20) were susceptible to MTZ. Resistance to metronidazole was defined as aerobic MIC ≥50 μg/ml, which was not detected in any of the isolates. The mean aerobic MIC and MLC and the mean anaerobic MIC of the parasites were 3.8, 3.2 and 2.1 μg/ml, respectively. Conclusion: The present study was the first to investigate drug susceptibility in T. vaginalis isolates in Bushehr city. Since no metronidazole-resistant isolates were found, the situation looked very promising. Nevertheless, the need for larger-scale research is inevitable in the province. Considering that most results are based on in vitro observations, conducting an in vivo study has also been recommended in recent years, as these studies could help develop real standards about clinical and microbiological responses to MTZ treatment.

A 36-year-old woman with symptomatic metronidazole-resistant trichomonal vaginitis for 10 years had a total of 22 courses of treatment with either metronidazole or tinidazole according to different schedules. The minimum trichomonicidal concentration of metronidazole for the strain of Trichomonas vaginalis isolated from the patient was 160 microgram/ml compared with 1.25-10 microgram/ml for oth...

We determined the susceptibilities of five strains of Trichomonas vaginalis, one of which was metronidazole resistant, to 50 antimicrobial agents. For the metronidazole-susceptible strains, the most active agents were metronidazole, tinidazole, mebendazole, furazolidone, and anisomycin. Against the resistant strain mebendazole, furazolidone, and anisomycin were the most active. Antifungal agent...

The in vitro activities of tinidazole and metronidazole against Trichomonas vaginalis isolates clinically resistant to metronidazole were compared. Minimal lethal concentrations (MLCs) of tinidazole were significantly lower than MLCs of metronidazole. Increased metronidazole resistance correlated with increased tinidazole resistance. These data support a role for tinidazole in the treatment of ...

Ninety-four strains of Trichomonas vaginalis isolated from unselected patients in Vienna during the period from November 1975 to November 1975 were subjected to sensitivity tests against metronidazole in vitro and in vivo. Nearly 90% of the isolates examined showed in vitro growth inhibition at concentrations of 0.4 to 1.6 microgram metronidazole/ml and only about 10% at concentrations of less ...
