Livers (n = 80) of slaughtered adult buffaloes were examined for pathological changes during the period from July 2006 to March 2007 in two slaughterhouses of Barisal district. Livers exhibiting gross alterations were cleaned with normal neutral saline and the changes were recorded. The lesions containing tissue samples were collected in 10% buffered formalin for fixation. Grossly, Gigantocotyle explanatum infection (amphistomiasis) was found in 31.25% and Fasciola gigantica infection was in 22.5% cases. Hydatidosis (2.5%), abscesses (3.75%), and haemorrhages (2.5%) were found in the liver. Histopathologically, cirrhosis was found in 31.25% cases. Nodular hepatitis 7.5%, granulomatous hepatitis 5% and parasitic cholecystitis 15% were also recorded during the investigation. Survey showed that the severity of infection with G. explanatum 31.25% and F. gigantica 22.5% and cirrhosis 31.25% were of highest percentage.   Key words: Liver, amphistomiasis, hydatidosis, granulomatous, cholecystitis, cirrhosis, Fasciola gigantica DOI = 10.3329/bjvm.v5i1.1321 Bangl.

Bovine uterine horns with both ovaries containing a corpus luteum (CL) were compared for progesterone (P4) and oxytocin (OT) concentrations during the luteal phase of the estrous cycle. Uterine tissue samples from five Holstein cows with bilateral CL obtained from the slaughterhouse were used for this study. No significant difference was observed in P4 and OT levels in the right and left horns with corpora lutea in both ovaries. The data clearly indicate that both sides of the uterine horn having a functional CL are exposed to similar levels of P4 and OT, supporting the hypothesis that luteal products are delivered locally to the uterus.

An investigation was carried out on incidence and pathology of fascioliasis in deer of Chittagong Zoo and some houses of Chittagong city during the period from January 2001 to June 2004. A total of 57 domesticated deer of various types were examined to diagnose the fascioliasis in Chittagong zoo and some house deer of Chittagong city. By faecal examination out of 44 cases 34 (77.3%) were positive for fascioliasis, of which, 15 (34.1%) cases were recorded in Chittra deer, 12 (27.3%) in Maya deer, 05 (11.4%) in Shambar deer and 02 (4.5%) in Nathrini deer. In post mortem examination, fascioliasis found in 13 (100%) cases, of which, 08 (61.5%) from Chittra deer and 05 (38.5%) from Maya deer. The overall incidence of fascioliasis in deer was 82.5%. In relation to sex the fasciolasis was significantly (p < 0.05) higher in female (82.6%) than male (71.4%) deer. The incidence of fascioliasis in various types of deer in relation to age was significantly (p < 0.05) higher in age group of above 2 years old than in age group below 2 years old. The gross examination revealed enlarged livers with round edges and thickened capsule with numerous haemorrhagic spots on the parietal surface (subacute form). In chronic form, the livers were cirrhotic and reduced in size. The affected intra-hepatic bile ducts were protruded and were engorged with flukes. Microscopically the migratory tracts were represented by the presence of haemorrhagic, oedema and infiltration with numerous eosinophils mixed with few lymphocytes. The wall of the bile ducts was thickened with fibrous tissue proliferation and the lining epithelium showed hyperplastic changes.

Rationale Immunoglobulin (Ig) G4-related disease (IgG4-RD) is a novel clinical disease entity characterized by an elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4-positive plasma cells. Pathological changes are most frequently seen in the pancreas, lacrimal glands, and salivary glands, but pathological changes in the lung also exist. Linker for activation of T cell (LAT)Y136F knock-in mice show Th2-dominant immunoreactions with elevated serum IgG1 levels, corresponding to human IgG4. We have reported that LATY136F knock-in mice display several characteristic features of IgG4-RD and concluded that they constitute an appropriate model of human IgG4-RD in salivary glands, pancreas, and kidney lesions. Objectives The aim of this study is to evaluate whether lung lesions in LATY136F knock-in mice can be a model of IgG4-related lung disease. Methods Lung tissue samples from LATY136F knock-in mice (LAT) and wild-type mice (WT) were immunostained for IgG1 and obtained for pathological evaluation, and cell fractions and cytokine levels in broncho-alveolar lavage fluid (BALF) were analyzed. Results In the LAT group, IgG1-positive inflammatory cells increased starting at 4 weeks of age and peaked at 10 weeks of age. The total cell count and percentage of lymphocytes increased significantly in BALF in the LAT group compared to the WT group. In BALF, Th2-dominant cytokines and transforming growth factor-β were also increased. In the LAT group, marked inflammation around broncho-vascular bundles peaked at 10 weeks of age. After 10 weeks, fibrosis around broncho-vascular bundles and bronchiectasis were observed in LATY136F knock-in mice but not WT mice. Conclusions LATY136F knock-in mice constitute an appropriate model of lung lesions in IgG4-RD.

The prevalence of haemoprotozoa in duck and pathological changes produced by these parasites were studied in different areas of Mymensingh district during July, 2007 to December, 2007. In this study 60% ducks were found to be infected with haemoprotozoa. Two species of haemoprotozoa were identified such as Leucocytozoon caulleryi and Leucocytozoon simondi. Prevalence of L. caulleryi (54.67%) was significantly (P < 0.01) higher than that of L. simondi (5.33%) in ducks. The calculated odds ratio implied that ducks were 19.67 times more susceptible to L. caulleryi infection than L. simondi infection. Prevalence of haemoprotozoa was significantly (P < 0.01) higher in male (78.94%) than female ducks (53.57%). Pathological lesions were observed in case of Leucocytozoon sp. infections. Grossly lungs were congested but other suspected organs such as liver, lungs, kidney and heart were apparently normal. Microscopically, comma shaped organisms were found in the hepatocyte of liver and alveolar epithelial cell of lungs accompanied with eosinophilic infiltration. Schizonts were also observed in the hepatocyte of liver and alveolar epithelial cell of lungs. The lungs alveoli were distended and ruptured in advanced stages. According to the result, it may be concluded that haemoprotozoan infection in duck is highly prevalent in Bangladesh and produces clinicopathological lesions in duck. So proper control measures should taken to reduce the prevalence of haemoprotozoa of duck in Bangladesh. Key words: Haemoprotozoa, ducks, prevalence, pathology DOI = 10.3329/bjvm.v6i1.1339 Bangl. J.

Esophageal Test

The esophagus is a tubular structure spanning from the posterior pharynx, through the thorax, and terminating in the stomach. It arises from endodermal foregut tissue. Its submucosal muscular layers are initially striated, transitioning to smooth muscle in more distal areas. Due to the distance in the body it traverses, the esophagus derives its blood and nerve supply from several structures. The role as a conduit from mouth to stomach necessitates secretory and barrier functions, as well as sphincters for protection from anterograde flow. Various modalities of esophageal test exist, ranging from fluoroscopy, to invasive endoscopy capable of obtaining tissue samples, to probes that detect pH and muscle tone, all of which play roles in identifying various pathologic processes.

This study was undertaken with the aims of evaluating the efficiency of the PCR assay in investigation of the epidemiological status of tropical theileriosis in comparison with the classical microscopic examination of Giemsa-stained blood smear and detecting the gross and microscopic pathological changes in some organs of the infected animals. Blood and tissue samples were collected from 50 apparently healthy, tick-infested cattle during the period extended from the 1st of July to the 31st of August, 2008 in the modern slaughterhouse in Sulaimaniyah province. Blood smears were prepared from the blood samples and stained with Giemsa dye. The tissue samples were obtained from normal and lesion-presenting tissues of the lymph nodes, lungs and kidneys were investigated by the naked eye for the presence of any pathological changes. Following gross examination, the tissue samples, of the cattle that showed positive results for Theileria annulata parasites by PCR and Giemsa-stained blood smears, have processed for histopathological preparations.When compared with microscopic examination of Giemsa-stained smears, the PCR assay detected a positive results in 8 (16%) of blood samples that revealed negative microscopy indicating that the PCR is more sensitive in diagnosis of tropical theileriosis. The gross pathological examination revealed lymph nodes enlargement, pulmonary congestion and edema and multiple pale areas in the kidneys. Microscopically, the principle pathological lesion was represented by a marked lymphoproliferative reaction within these organs.

Background: Odisha experiencing sporadic outbreaks of Peste des petits ruminants (PPR) throughout the year. There is a scarcity of available literature on PPR in Odisha till today. This is the first ever detail investigative approach in the state undertaken with an objective to corelate the epidemiological risk factors, haemato-biochemical and pathological changes in natural field outbreaks occurring in eight different districts. Methods: Fourteen field outbreaks of PPR were evaluated clinically as well as epidemiologically and confirmed through polymerase chain reaction (PCR). Blood, serum, faecal and tissue samples were collected to observe haemato-biochemical and pathomorphological changes to asses disease severity. Result: Present study concluded an overall mortality rate of 46.81%. Chi-square analysis revealed significant highest prevalence among 7-12 months (46.13%) age, Ganjam breed (45.51%) and females (80.49%). Frequent migration among the border areas along with poor management and helminthic infection was major precipitating factor. There was polycythemia along with neutrophilia and lymphopenia. Significant increase in alanine transaminase (ALT), aspartate aminotransferase (AST), K+ and Ca+2 along with creatinine, urea and blood urea nitrogen (BUN) BUN was observed in affected flocks. Antero-ventral consolidation of lungs, syncytia and presence of both eosinophilic intranuclear and intracytoplasmic inclusion bodies were major pathological changes.
