background and objectives : in iran, anaplasmosis is normally diagnosed with traditional giemsa staining method. this is not applicable for identification of the carrier animals. the aim of this study was to compare the detection of anaplasma marginale in two different numbers of microscopic fields (50 and 100) using conventional giemsa staining method compared with the pcr-rflp technique. mate...

INTRODUCTION Tuberculosis causes illness among millions of people each year and ranks as the second leading cause of death from infectious disease worldwide. The aim of this study was to investigate the detection rate of microscopic examination and estimate risk of transmission of TB by smear negative pulmonary TB patients. METHODS A cross-sectional study and retrospective data analysis on TB...

most sweet cherry cultivars are as found as self-incompatible and therefore for commercial fruit production, compatible pollinizers are needed. controlled pollination and microscopic examination of pollen tube growth in the style are two classical methods for determination of compatible and incompatible pollen donor cultivars. this experiment was carried out to explore the compatibility of ‘zar...

Mutual relationship between pasture grasses and Neotyphodium fungal endophytes is of great importance in grass improvement. Two endophyte containing tall fescue genotypes (75 and 83) and their endophyte free ramets were used in this study. Endophytes were isolated from tall fescue genotypes 75 and 83 and used in three methods of inoculation including Latch and Christensen approach, insertion of...

twenty patients, a family, their neighbors, and friends; with lesions suspicious of ringworm infection, were referred to us within a period of 80 days. the source of infection was found to be 3 persian cats (a mother and two kittens) living with the family. the cats had multiple lesions around their nose and on abdomen which reveales the prevalence of cutaneous fungi both on direct microscopic ...

We report herein a case of isolated Rosai-Dorfman disease (Sinus Histiocytosis with Massive Lymphadenopathy) diagnosed upon routine microscopic examination of tonsils in a child. The patient is a 4-year-old girl who had a history of sleep apnea, but no other significant medical history or other findings on physical examination. In this report, we discuss the various approaches to handling of to...

OBJECTIVES This study aims to evaluate the alterations in distances to the surgical margins on sheep tongue specimens, through resection, formalin fixation, frozen section, and microscopic examination. MATERIALS AND METHODS Fifty fresh sheep tongues were used in the study. A metal plate was fixed on the lateral aspect of each tongue to represent tumor tissues. A total of 40 specimens with eit...

On necropsy of a 24 months age Dutch female rabbit the uterine horns seems enlarged with a nodular appearance. On the cut surface of the uterus as well as heart wall, white firm masses with a cauliflower- like surface was observed. No other important gross lesions were found in other organs. In histopathological examination of the uterus typical microscopic changes were those of adenocarcinoma....

Background: Trichomonas vaginalis is a common pathogen with worldwide distribution. It is estimated that worldwide 180 million people are infected annually. Trichomoniasis is associated with vaginitis, cervicitis, low birth weight, and preterm delivery in pregnant women in addition, it is a cofactor in HIV transmission. Diagnosis of disease is traditionally depends on the microscopic observatio...
