Objectives:Anaplasmosis is an economically important disease affecting cattle, buffalo, sheep, goat etc. The study was conducted to determine the prevalence, potential risk factors and molecular identification of circulating Anaplasma spp. in goats in Chattogram district, Bangladesh. Material and methods:Four hundred blood samples were collected from goats of different ages, breeds, sex, coat color and body condition. These goats were selected based on some inclusion criteria through the period of July 2017 to June 2018. Samples were examined microscopically (Giemsa staining method) followed by polymerase chain reaction (PCR) and sequencing to identify of Anaplasma spp. Results:The overall prevalences were estimated 5.75% (23/400) and 15.75% (63/400) by microscopy and PCR, respectively. Anaplasma ovis (A. ovis) and Anaplasma marginale (A. marginale) were identified with the prevalence of 14.75% (59/400) and 1.0% (4/400), respectively through PCR. Among different risk factors, jamnapari breed (p = 0.027), no use of acaricide (p = 0.025) and presence of tick (p < 0.01) were found to be significantly associated with anaplasmosis. Sequence analysis of msp4 gene revealed that, Anaplasma spp. detected in the present study were highly similar with those of China,

Background: Diclofenac sodium is a non-steroidal anti-inflammatory drug with reportedly undesirable harmful side effects including blood disorders, abdominal pain, ulceration and bleeding of the stomach or intestine. Objective:The present study was conducted to investigate the effect of diclofenac sodium on erythropoiesis, on stomach and liver under different conditions. Method: This experimental study on animal model was conducted in the Department of Physiology, Bangladesh Agricultural University, Mymensingh, between July and August 2007. A total of 45 Swiss Albino mice were randomly assigned into five equal groups (n=9) and they all were fed with standard broiler pellet (25 gm/mice/day) throughout the experimental period of 40 days. Keeping 1 group as control(groupA), 4 groups were treated with diclofenac sodium @ 3 mg/kg body weight (bwt) orally in empty (group B)or full stomach with (group c) or without vitamin B12(group D) @ 10 µg/Kg body weight through intramuscular route. Total erythrocyte count (TEC) and Hb% was determined to assess erythropoiesis. Macroscopic and microscopic changes of liver and stomach were studied by standard laboratory method. Data were analyzed statistically by ANOVA and un paired t test. Result: Oral administration of this drug significantly (p<0.01) decreased Total Erythrocyte Count(TEC) and Hb in the animals treated with diclofenac sodium in empty stomach and in the animals treated with diclofenac sodium plus vitamin B12 in empty stomach. All the treated mice showed slight to moderate congestion of the gastric mucosa and liver. Conclusion: Intake of diclofenac sodium in empty stomach may produce harmful side effect on stomach and liver.

Duck plague is an enveloped DNA virus that belongs to the Anatid Herpes Virus; the Herpesviridae family is an acute and highly infectious duck, geese, and swan disease that causes tremendous economic losses of duck rearing in Bangladesh and other duck rearing countries. Therefore, we decided to isolate duck plague virus from recent fields’ outbreaks area and performed molecular detection and phylogenetic analysis to find out the similarities between our findings and other isolates around the world. Visceral organs of 13 suspected ducks from recent outbreaks area were collected by post-mortem examination for inoculum preparation. Several passages were performed to harvest into 9-11 old embryonated eggs Chorioallantoic membrane (CAM) route and duck embryo fibroblast (DEF) primary cell culture. DNA polymerase (446bp) and DNA polymerase (UL, 602bp) genes were used for molecular detection by Polymerase chain reaction (PCR). Pathogenicity was done with duckling and TCID50 on DEF. Molecular characterization was performed from extracted DNA of duckling and 2 Positive PCR products were partially sequenced for phylogenetic analysis of their origin and nucleotide variations. Sequenced data was analyzed to reveal genetic relationships among constructed phylogenetic tree for understanding potential transmission with origin of virus and data was then submitted to gene bank and got accession number for DPV-BR1-MN937272 and DPV-BR-2-MN937273. Among 13 samples, 4(30.77%) were found positive by PCR using DNA polymerase at 446 bp and UL at 602 bp gene. Chorioallantoic membrane (CAM) was observed hemorrhagic after 72 days and duck embryo fibroblast (DEF) become round as showed cytopathic characteristics after 48h of infection .Duckling showed that isolated virus was highly pathogenic as characteristics signs of post-mortem examination. Therefore, this has found that recent isolates have similarity with Bangladesh, India and China isolates. Moreover, TCID50 has confirmed the isolates have accepted titer to be a vaccine strain. Res.

The clinical condition of the patient, type of central venous catheter (CVC), site and duration of CVC placement are the factors affecting the risk of infection. The aim of this study was to examine and find out the risk factors of CVC related blood stream infections (CVC-BSI). This cross sectional study was carried out in the Department of Microbiology and Immunology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh during the period of July 2011 to June 2012. One hundred patients who were admitted in ICU of BSMMU and ICU and haemodialysis unit of Dhaka Medical College Hospital (DMCH) having central venous catheter, were enrolled in the study. The rate of CVC-BSI was 11% and the incidence was observed to be 11.14/1000 catheter days. Both CVC-BSI and CVC colonization were higher in trilumen than in bilumen central venous catheter. CVC-BSI rate was 12.79% in trilumen whereas there was no CVC-BSI in patient with bilumen catheter. The mean duration from CVC insertion to development of CVC-BSI was 14 days, CVC colonization was 8.41 days and noninfected CVC was 6 days. CVC-BSI and CVC colonization were most common in right femoral vein where CVC-BSI was 18.52% and CVC colonization was 59.26%, whereas no CVC-BSI was found in right internal jugular vein. Risk factors for CVC-BSI included type of CVC, site of CVC placement, duration of catheterization were not found statistically significant in this study. CVC-BSI and CVC colonization were higher in trilumen catheter and rate raised with increased duration of placement and highest number of CVC-BSI and colonization was found in right femoral vein.
