Trichomoniasis

Trichomoniasis, a sexually transmitted disease (STD), is caused by Trichomonas vaginalis in both men and women. Screening of trichomoniasis is problematic in resource challenged settings as currently available, inexpensive diagnostic methods are of low sensitivity and/or specificity. In India, National AIDS Control organization (NACO) recommended syndromic case management (SCM) for treatment. The objective of the present study was to compare the utility of the NACO-NACP III Algorithms for STI/RTI treatment used by clinicians with PCR based diagnosis. Patients visiting Department of Obstetrics & Gynecology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi from January 2011 to June 2014 were enrolled in the study to compare the diagnostic efficiency of PCR-based assays against SCM. Based on SCM, patients (n = 820) were treated with antibiotics using pre-packed STI/RTI kits (sexually transmitted infection/reproductive tract infection; procured by National AIDS Contro...

The effect of iron on MLC of metronidazole on in vitro cultured T. vaginalis isolates was investigated. Addition of iron decreased metronidazole MLC in both aerobic and anaerobic assays. Supplementary iron intake with metronidazole in treatment of trichomoniasis is recommended.

This article presents modern data on epidemiological trends, pathogenesis, and mechanisms of persistence and acquisition of antibiotic resistance of the most common sexually transmitted infections (STIs): chlamydial infection, gonorrhea, trichomoniasis. Data on the frequency of chlamydial infection, gonorrhea, trichomoniasis detection in the DILA medical laboratory in the period from 2018–2020 are also presented.
Analysis of epidemiological and microbiological studies indicates a significant increase in the STIs incidence in countries with high economic development and the need for constant revision of diagnostic and treatment approaches, based on new data on the pathogens physiology, mechanisms and levels of antibiotic resistance, possibilities of laboratory diagnostics. Analysis of the DILA data on the chlamydial infection, gonorrhea, trichomoniasis detection is coinciding with the world trends in the increase of their prevalence. At the same time, the analysis of the DILA data demonstrated an interesting clinical phenomenon as a presence of 2 STIs peaks in women: the first at 21–25 years and the second at 51–55 years old.
Clinical manifestations of STIs are increasingly losing their typical features today. This indicates the need for a laboratory search for all common STIs in the region. Knowledge of the etiological factor of the inflammatory process allows choosing the correct antibiotic therapy and preventing the further development of antibiotic resistance. This article presents data on the various methods of STIs laboratory tests. Regular visits of women for cervical cancer screening are a good opportunity to screen for STIs. The ability to detect STIs in biomaterial in liquid cytology makes this option more accessible.
Thus, since vaccines against common bacterial and protozoa STIs pathogens have not yet been developed, the promotion of hygiene of sexual behavior and timely detection of infected persons during examination or screening with subsequent etiopathogenetic treatment are the basis of the STIs control systems and their consequences prevention.

In recent decades Cooper's Hawks have successfully colonized urban landscapes, where there may be ample prey but also a greater prevalence of disease in their prey. We searched for nesting Cooper's Hawks in and around Berkeley, California, from 2002 to 2010, locating 95 nests, 89 of which successfully fledged at least one nestling. On average, each nest produced 3.6 fledglings. We evaluated the possible effects of the protozoan parasite Trichomonas gallinae on Cooper's Hawk reproduction from the proportion of potential prey items brought to Lindsay Wildlife Experience that tested positive for the parasitic disease. We did not find a correlation between T. gallinae in potential prey species and nest success (i.e., if the nest fledged any offspring) or reproductive success (i.e., number of fledglings produced). Similarly, we did not find a relationship between reproductive success and distance to parks or percent of impervious surface within 500 m of the nest. The high reported rates of reproduction and high densities of Cooper's Hawk in Berkeley and neighboring Albany suggest a robust population, and we did not find evidence that T. gallinae influences its reproductive success.

Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection, affecting an estimated 3.7 million women and men in the United States. Health disparities are prominent in the epidemiology of this infection, which affects 11% of women aged ≥40 years and a disproportionately high percentage of black women. Particularly high prevalences have been identified among sexually transmitted disease (STD) clinic patients and incarcerated individuals. This article reviews and updates scientific evidence in key topic areas used for the development of the 2015 STD Treatment Guidelines published by the Centers for Disease Control and Prevention. Current evidence is presented regarding conditions associated with Trichomonas vaginalis infection, including human immunodeficiency virus (HIV) and pregnancy complications such as preterm birth. Nucleic acid amplification tests and point-of-care tests are newly available diagnostic methods that can be conducted on a variety of specime...
