Oral candidiasis is a serious problem for immunocompromised patients, especially patients with hematological malignancies. After becoming a systemic candidiasis it is difficult to diagnose, control and treat in individuals with hematological malignancies. The aim of this study was to diagnose candidiasis in the oral mucosa of patients with leukemias and lymphomas in a timely manner in order to prevent their progression to systemic candidiasis. In this cross sectional study, 50 clinical samples were collected from the mouth of patients with hematological malignancies undergoing chemotherapy from the oncology units of teaching hospitals in Kerman, Iran. Patients were from Kerman, Sistan-Baluchestan and Hormozgan in south-eastern Iran. Sampling was restricted to patients with diagnosed acute lymphoid leukemia (ALL); acute myeloid leukemia (AML); chronic lymphoid leukemia (CLL); chronic myeloid leukemia (CML); Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Presumptive species identification of fungi was performed using conventional methods like colony characteristics on CHROMagar Candida medium, germ tube production, and assessing the morphology fungi on corn meal agar. Confirmation of presumptive candida isolates was performed using PCR-RFLP. From a total of 50, 14 patients (28%) had positive oral candidiasis. Candida albicans (57.14%) was the most common species followed by Candida glabrata (14.28%), Candida parapsilosis (14.28%), Candida krusei (7.14%) and Candida kefyr (7.14%). Candida albicans had the highest rate of oral infection in ALL (35.71%) and then NHL (28.57%) patients. The results indicate that oral candidiasis is a prevalent fungal infection in the patients with hematologic malignancies with C. albicans being the main etiological agent. However, other species of Candida cause similar infections in these patients.

Dirofilariasis is a serious and potentially deadly condition in dogs and one of the zoonotic filarial infections, which inadvertently affects the humans. The objectives of this study were to determine the seroprevalence and the molecular identity of dirofilariasis in Kerman Province, southeastern Iran between Jul and Aug 2013.
A hundred and forty-nine domestic dogs were randomly selected and five ml blood samples were taken from each dog. One ml of anticoagulant (EDTA) was used for each test in the parasitological study (modified Knott´s test) and sera samples were examined, using ELISA kit to detect Dirofilaria immitis antigen. Extracted DNA of all positive blood samples was used for molecular characterization and sequencing.
Four (2.7%) domestic dogs of the total 149 domestic dogs were infected with micofilariae of D. immitis, while the serological study showed 8 (5.4%) domestic dogs were infected with D. immitis. No signifi­cant difference, however, was found between dirofilariasis infec­tion and gender. On the other hand, a signifi­cant difference was observed between dirofilariasis infec­tion and age (P Dirofilariasis occurred when there was low endemicity in the dogs. Such dogs could be a potential source of infection for humans. These findings could help in better understanding of the epidemiological aspects of D. immitis in the southeastern parts of Iran.
