Thirty-three fecal samples from cats were examined for the presence of Toxoplasma oocysts, and another 33 serum samples from these cats were subjected for Latex agglutination test & indirect immunofluorecent antibody test. Also 80 serum samples from ewes were subjected to the same serological tests. The study indicated that the prevalence of Toxoplasma oocysts in cats was 27.3%. Higher rates of antibody titer (68%) were observed in cats tested with latex test. Infection in young cats was higher than in adults. Sixty percentage of ewes were sero-positive with Latex test, but only 35% were sero-positive with IFAT, higher prevalence of antibody titers was observed in sheep from the three locations of Iraq. Ewes that had recurrent abortion showed higher prevalence in both tests than non aborted ewes.

El objetivo del presente estudio fue determinar la presencia de cepas de Escherichia coli (E. coli) y resistencia antimicrobiana en alimentos tipo BARF (Alimentos crudos biológicamente apropiados) para perros, comercializados en distritos de Lima, Perú. Se analizaron 124 muestras de dietas crudas congeladas pertenecientes a 15 marcas comerciales, cada muestra de distinto lote. Se realizó el aislamiento microbiológico estándar haciendo uso de medios de cultivo MacConkey y EMB, y su identificación por medio de pruebas bioquímicas. Para la serotipificación de E. coli O157 se utilizó Látex test (Oxoid TSMX4147C) con partículas de látex sensibilizadas con anticuerpos reactivos al antígeno somático O157, y para la identificación del antígeno H7, similar Látex test específico (RIM E. coli O157:H7 Latex Test - Oxoid TSMX9410). El 65.3% (81/124; IC95%: 56.9-73.7%) de las muestras fueron positivas a E. coli. Del total de colonias positivas a E. coli, 38.2% fueron resistentes a los 12 antimicrobianos en estudio.

The aim of the work was development of a monoclonal antibody-based latex agglutination test to identify the causative agent of melioidosis, and the approbation of a freeze-dried experimental preparation for screening of environmental bacterial isolates in Vietnam.Materials and methods. The carriers of specific antibodies were polyacrolein latex particles with active aldehyde groups on the surface. Typical strains of the causative agents of melioidosis and glanders with a full-fledged antigenic structure, as well as the strains Burkholderia thailandensis, Burkholderia cepacia, Pseudomonas aeruginosa, and Pseudomonas putida were used to control the test specificity. The latex agglutination reaction was carried out on plastic Petri dishes with daily bacterial cultures, from which suspensions were prepared at a concentration of 1–2·109 m.c./ml. The results of the reaction were registered visually for 5–8 min using a 4-cross system against a dark background under lighting. The reaction to 3–4 crosses was recorded as positive. Colonies suspected of belonging to pathogenic Burkholderia from primary inoculations were transferred to L-agar with polymyxin B and grown for 36 hours at (37±1) °C. The species of the selected suspicious colonies was determined by multiplex PCR.Results and discussion. With collection strains, latex test demonstrated high sensitivity agglutinating 97.7 % of B. pseudomallei and all B. mallei strains. At the same time, it was negative with B. thailandensis, B. cepacia, P. aeruginos and P. putida. In microbiological screening of bacterial cultures isolated from environmental objects, the latex test had a diagnostic sensitivity of 89.4 %. Using the latex test at the stage of primary screening, it is possible to significantly reduce the time when processing a lot of samples received for analysis, as well as to reduce the consumption of reagents used at the subsequent stages of identification. 


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.
