Water extract of Pulsatilla chinensis (PWE) (0.625 mg/ml) was added to the medium for the culture of Trichomonas vaginalis. After 2 h and 4 h treatment, the content and component of soluble proteins in the parasites were analyzed by SDS-PAGE. A total of 28 protein bands was demonstrated. After treated with PWE for 2 h, the content of 5 protein bands increased and that of 4 bands decreased significantly. Four hours later, a new protein band appeared in the electrophoretogram, and the content of 5 bands increased and that of other 5 bands decreased.

infects the urogenital tract of men and women and causes the sexually transmitted infection trichomoniasis. Since the publication of its draft genome in 2007, the genome has drawn attention for several reasons, including its unusually large size, massive expansion of gene families, and high repeat content. The fragmented nature of the draft assembly made it challenging to obtain accurate metrics of features, such as spliceosomal introns.

Metacaspases (MCA), are cysteine-dependent proteases closely related to caspases. In protozoa, MCA plays an important role in programmed cell death (PCD). In Trichomonas vaginalis, a kind of PCD that resembles apoptosis has been described, but the activators of this mechanism have not been demonstrated.

Introduction: Sexually transmitted infections (STIs) in pregnancy are associated with an increased risk of vertical HIV transmission and adverse pregnancy and birth outcomes. In South Africa, syndromic management is the standard of care for STI management. We assessed the potential impact of point-of-care (POC) screening for curable STIs (Chlamydia trachomatis [CT], Trichomonas vaginalis [TV] and Neisseria gonorrhoeae [NG]) during pregnancy on vertical HIV transmission and adverse pregnancy and birth outcomes.

The path to survival for pathogenic organisms is not straightforward. Pathogens require a set of enzymes for tissue damage generation and to obtain nourishment, as well as a toolbox full of alternatives to bypass host defense mechanisms. Our group has shown that the parasitic protist encodes for 14 sphingomyelinases (SMases); one of them (acid sphingomyelinase 6, aSMase6) is involved in repairing membrane damage and exhibits hemolytic activity.

Purpose Of Review: Antimicrobial resistance in sexually transmitted infections (STIs) has become an urgent global public health threat, raising the specter of untreatable infections. This review summarizes the determinants of resistance among the five most common curable STIs Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Treponema pallidum, and Trichomonas vaginalis, as well as strategies to mitigate the spread of resistance.
Recent Findings: Genetic mutations are key drivers of resistance for N.
