Background: Trichomoniasis is an extremely common sexually transmitted infection (STI) worldwide and is associated with important public health problems, including amplification of HIV transmission. This disease is in forms of symptomatic and asymptomatic in women and may depend on host as well as parasite variables. Most of the studies reported from females are based on examination of vaginal secretions and urine samples by direct smear and culture in modified Diamond's media. The aim of this study was checking the samples, which were negative by direct smear and culture, with PCR technique.
Methods: The urine samples and vaginal discharge of patients attending Gynecology Clinics of Mazandaran Province, Iran with different symptoms rechecked for Trichomonas vaginalis by PCR technique using primers targeting a conserved region of the beta-tubulin genes of the parasite. Data were analyzed by Epi Info software program
Results: Out of 161 negative samples by direct smear and culture, seven samples (4.3%) were positive by PCR technique.
Conclusion: Diagnosis of trichomoniasis by PCR is a sensitive and specific method that could play important role to help the physicians for properly treatment and control of infection.

The order Passeriformes is the richest and most abundant group of birds, but despite numerous parasites being identified in wild birds, this order has received limited focus. This study analyzed 17 passerines admitted to the Grupo de Rehabilitación de la Fauna Autóctona y su Hábitat (GREFA), a wildlife rehabilitation center in Spain, during October to December 2022. Necropsies were conducted to determine the presence of parasites, and intestinal contents were analyzed using fecal smear, flotation and sedimentation techniques and the McMaster method.

Article Synopsis
- Over 95% of global parasitic infections are linked to poverty, poor hygiene, and contaminated water, with a significant impact on children, especially in Madagascar where many live below the poverty line.
- A study conducted in October 2023 examined 241 school children in Madagascar’s Mampikony district, using various diagnostic methods to analyze stool samples for intestinal parasites.
- The study found a high prevalence of 71.0% of intestinal parasites, with 27.0% of children infected by pathogenic types, particularly Giardia intestinalis and Blastocystis spp., highlighting the urgent need for effective prevention strategies in the local community.
