Salmonella Reading: A rare case of generalized salmonellosis in non-endemic region

Salmonella Reading is a rare serotype of Salmonella enterica and is associated with sporadic cases and rare outbreaks worldwide. This article describes a rare case of generalized S. Reading infection imported from Indonesia to Moscow, Russia. A 37-year-old man was admitted to the hospital with fever, weakness, and headache after returning from Indonesia. During his stay in Indonesia, he developed symptoms of a gastrointestinal infection, which resolved there. However, upon return to Moscow, his condition worsened due to high fever, and he was diagnosed with a generalized salmonellosis caused by S. Reading (positive blood and stool culture). This case highlights the importance of differential diagnosis in patients with fever. The health risks associated with traveling to exotic countries and the importance of preventive measures are emphasized. This is the first published case of S. Reading in Eastern Europe.

Difficulties in the diagnosis of D. repens in the inguinal lymph node.

D. repens is the causative agent of subcutaneous dirofilariasis in canine animals. In recent years, human invasion by this vector-borne helminthiasis has been recorded in many countries with temperate climate, but the localization of this helminth in the cavities of the human body is extremely rare. Cases of atypical localization of D. repens are described in the organs of the chest, cervical lymph node, in the spermatic cord and epididymis. It is usually requires differential diagnosis with neoplastic or metastatic processes. We report a case of the detection of Dirofilaria repens in the right inguinal lymph node in a 56-year-old woman. Helminth was identified by parasitological and molecular biological methods. A morphological study of cross sections of the nematode in histological preparations and molecular biological method, the polymerase chain reaction (PCR) of scrapings of histological material, were used in parallel.
