Background: Diarrhea is a main cause of morbidity and mortality in children under 5 years old. Globally it is responsible for approximately four billion cases and three million deaths annually. In developing countries, it causes two million deaths each year. The major causative organism is rotavirus which is responsible for one-third of hospitalizations with approximately 40% mortality. Objectives: To determine the prevalence and demographic characteristics of rotavirus infection in Babylon city, Iraq. Materials and Methods: Fecal samples were taken from children with age range of 6 months to 5 years complained of diarrhea during the period beginning in October 2016 till August 2017. The age, gender, residence, the type of feeding, place of the sample collection and duration of diarrhea were recorded. Specimens were analyzed by Latex test for detection of rotavirus. Results: A total of 349 children presented with diarrhea, the rotavirus antigen was detected in 169 fecal specimens from children with diarrhea (48%). More percentages of positive rotavirus specimens were seen in the 5year of age. No gender differences were observed, meanwhile samples obtained from rural areas and breastfed children showed less rotavirus positive infection. Conclusion: The present study confirms that rotavirus infection is still currently a prevalent gastroenteritis causative agent and required careful clinical attention. Pediatricians and health care providers are needed to be encouraged to take into account the children who at risk for developing rotavirus infection including age, residence and type of feeding.

Colletotrichum Gloeosporioides Species Complex

A survey was conducted in twenty-five cashew (Anacardium occidentale) orchards in five communities in the Dormaa-Central Municipality of Bono Region of Ghana to assess the incidence and severity of anthracnose, gummosis and die-back diseases on cashew. Cashew diseased samples of leaves, stem, inflorescences, twigs, flowers, nuts and apples showing symptoms (e. g. small, water-soaked, circular or irregular yellow, dark or brown spots or lesions on leaves, fruits and flowers, sunken surface, especially on the apples, blight, gum exudates) were collected for isolation of presumptive causative organism. The pathogen was isolated after disinfecting the excised diseased pieces in 70% ethanol, plated on potato dextrose agar (PDA) and incubated at 28 oC for 3 to 7 days. The identity of the putative pathogen was morphologically and culturally confirmed as belonging to Colletotrichum gloeosporioides species complex using standard mycological identification protocols. The pathogen had varied conidia sizes of between 9-15 up to 20 μm in length and diameter of 3-6 μm. The conidia were straight and cylindrically shaped with rounded or obtuse ends. The septate mycelium was whitish-grey, velvety and cotton-like in appearance from the top. The results confirmed the presence of the pathogen in the orchards with incidence ranging from 6.9% and 14.0% for gummosis and averaged 22.9% for anthracnose infected orchards. The result of the pathogenicity test confirmed the isolates to be pathogenic on inoculated cashew seedlings and were consistently re-isolated, thereby establishing the pathogen as the true causal agent of the said diseases in cashew trees and thus completed the Koch’s postulate.

Background: Mycobacterium tuberculosis is a causative organism of tuberculosis, which is most deadly disease after cancer in a current decade. The development of multidrug and broadly drug- resistant strains making the tuberculosis problem more and more critical. In last 40 years, only one molecule is added to the treatment regimen. Generally, drug design and development programs are targeted proteins whose function is known to be essential to the bacterial cell. Objectives: Reported here are the development of 'S', 'N’ heterocycles as antimycobacterials targeting fatty acid biosynthesis. Material and Methods: In the present communication, rational development of anti-mycobacterial agent's targeting fatty acid biosynthesis has been done by integrating the pocket modelling and virtual analysis. Results: The identified potential 33 lead compounds were synthesized, characterized by physicochemical and spectroscopic methods like IR, NMR spectroscopy and further screened for antimycobacterial activity using isoniazid as standard. All the designed compounds have shown profound antimycobacterial activity. Conclusion: In this present communication, we found that 3c, 3f, 3l and 4k molecules had expressive desirable biological activity and specific interactions with fatty acids. Further optimization of these leads is necessary for the development of potential antimycobacterial drug candidate having less side effects.

Abstract Background Malignant otitis externa is a fatal infection of the external ear and temporal bone. Pseudomonas aeruginosa is the most common causative organism, while fungi are a rare cause of malignant otitis externa. We aimed to compare the clinical, therapeutic and evolutionary features between bacterial and fungal malignant otitis externa. Methods We conducted a retrospective study including all patients hospitalized for malignant otitis externa in the infectious diseases department between 2000 and 2018. Results Overall, we encountered 82 cases of malignant otitis externa, among which there were 54 cases (65.9%) of bacterial malignant otitis externa (BMO) and 28 cases (34.1%) of fungal malignant otitis externa (FMO). The males were predominant among BMO cases (57.4% vs 50%; p=0.5). Patients with FMO were significantly older (70±9 years vs 61±10 years; p< 0.001) and had medical history of diabetes mellitus more frequently (96.4% vs 77.8%; p=0.03). The use of topical corticosteroids was significantly more reported among FMO cases (28.6% vs 5.6%; p=0.006). Otalgia (96.4% vs 81.5%), otorrhea (75% vs 66.7%) and cephalalgia (46.4% vs 42.6%) were the revealing symptoms among FMO and BMO, respectively, with no significant difference. Tenderness to palpation of the mastoid bone (64.3% vs 38.9%; p=0.02) and stenosis of the external auditory canal (92.9% vs 72.2%; p=0.02) were significantly more frequent among FMO cases. Complications were significantly more frequent among FMO cases (42.9% vs 9.3%; p< 0.001). Treatment duration was significantly longer among FMO cases (70[40-90] days vs 45[34-75] days; p=0.03). Conclusion Our study showed that FMO affected more frequently the elderly and diabetic patients, when compared with BMO. Regardless of the causative agent, the clinical presentation was similar. However, the outcome was poor among FMO cases with the occurrence of complications, requiring a longer duration of treatment. Disclosures All Authors: No reported disclosures

Abstract Inpatients with culture-positive diabetic foot infections are at elevated risk for subsequent invasive infection with the same causative organism. In outpatients with index diabetic foot ulcers, we found that wound culture positivity was independently associated with increased odds of 1-year admission for systemic infection when compared to culture-negative wounds.
