The Palpada genus, which belongs to the Diptera order (family, Syrphidae), has been rarely reported to cause accidental myiasis in humans. Herein, we report the first case of genitourinary myiasis caused by a larva of the Palpada genus in a 9-year-old girl from Colombia. The girl, who resided in a rural area in the municipality of Floridablanca, Santander, near Bucaramanga city, in eastern Colombia, presented with lower abdominal pain accompanied by oliguria, followed by the subsequent elimination of a larva through the urine. The next day, the patient visited a primary healthcare centre, and no signs or symptoms were observed on clinical examination. Haematological analysis showed high plateletcrit levels and platelet large cell counts. The results of the urine test revealed a decrease in specific gravity and a slight increase in bacterial content and mucus. DNA barcoding analyses showed that the etiological agent corresponded to a third instar larva of the Palpada scutellaris species. This is the first case to report genitourinary myiasis caused by larvae of the genus Palpada in humans. However, we believe that additional cases might be accurately detected if adequate tests are performed to confirm the clinical and molecular features associated with this infection.

Background: In this study, we investigated the genetic variability and population structure of the New World screwworm fly Cochliomyia hominivorax. We tested the hypothesis that the species exhibits a center-periphery distribution of genetic variability, with higher genetic diversity in central populations (e.g.

Parasitism, a widespread nutrient acquisition strategy among animals, results from a long evolutionary history where one species derives its metabolic needs from another. Parasites can significantly reduce host fitness, affecting reproduction, growth, and survivability. Vertebrate hosts exhibit defensive strategies against parasites, including "sickness behaviors" such as lethargy and self-grooming to remove ectoparasites.

A 70-year-old woman with a 6-month history of poor hygiene presented with a right occipital mass, ulceration, and neck swelling. The right occipital region was infested with approximately 100 fly maggots, and the mass contained a foul-smelling abscess. Maggots were removed, and the mass was drained, irrigated, and dressed with padding.

A patient in his 70s, admitted to the cardiac intensive care unit with cardiogenic shock, unexpectedly presented with nasal myiasis during a workup for persistently elevated inflammatory markers. CT scans revealed sinusitis and bronchial secretions, while bronchoscopy identified mucus with positive pathogen testing. Nasal endoscopy was crucial in diagnosing myiasis, and immediate mechanical removal of larvae was performed.

Background: is one of the most important parasites, which infests the upper respiratory tract of camels leading to deteriorating health effects, substantial economic losses, and even death.
Aim: This study aimed to detect the prevalence rate of in slaughtered camels, determining its morphology using the electron microscope, and confirming its species by molecular phylogeny.
Methods: A total of 200 slaughtered camels at different areas in Al Muthanna province (Iraq) were inspected visually to collect the parasite samples that were identified initially based on their morphological characteristics.
