A study was carried out on indigenous layer chickens to know occurrence of Avian Pasteurellosis (AP) and Newcastle disease (ND) in Sirajgonj during the period from January/2012 to December/2013. The clinical signs showed before death was recorded by taking history and the birds were subjected to post mortem examination. In addition to the clinical and necropsy findings, ND was detected by Anigen® rapid antigen detection kit. The AP was confirmed by isolation and identification of Pasteurella (P.) multocida from liver, spleen and heart samples. The P. multocida was found to grow on nutrient broth, nutrient agar, blood agar and Eosin Methylene Blue agar where it produced whitish, opaque, round, flat, translucent colonies. It produced turbidity on nutrient broth. The organism was not found to grow on MacConkey agar media and did not cause hemolysis on blood agar media. The impression smear of liver and heart blood were stained by Gram’s staining, Leishman staining and Methylene blue staining techniques to detect P. multocida. P. multocida organism was also found to fermnt dextrose, lactose and mannitol with the production of only acid but did not ferment maltose and lactose. P. mutocida was found non-motile, indole positive and urease negative. On triple sugar iron test it produced H2S and fermented only glucose. It was found negative to both methyl red test and Voges Proskauer test. Out of 360 birds tested 59.72% (215) was AP positive and 40.28% was ND positive. Age, Sex, season and mortality due to other diseases were not considered.DOI: http://dx.doi.org/10.3329/bjvm.v11i2.19123 Bangl. J. Vet. Med. (2013). 11 (2): 97-105

Mycobacterium avium complex-serotype 6 was isolated in pure culture on blood agar plates from inocula taken from the heart blood, lungs, liver, kidneys, and spleen of a naturally infected captive female opossum (Didelphis marsupialis virginiana). Repeat cultures from stored tissues and transfer of colonies from original blood agar plates revealed that the mycobacterium grew on tryptose, brilliant green, eosin-methylene blue. Sabouraud glucose, and mycobiotic agar plates and in Fletcher leptospira medium. The cultural, biochemical, and serological characteristics of the test isolate were compared with other mycobacteria. This is the first report to describe the primary isolation of a serotype from the M. avium complex from an animal species on blood agar or in Fletcher broth. In addition, this is the second documented report describing the isolation and identification of a mycobacterial species from the American opossum.

We present a proposal on the standards used on ootaxonomy practices and techniques in the butterfly family Pieridae Duponchel (Lepidoptera: Papilionoidea) in five stages: 1) getting the specimens, 2) integration into a collection, 3) dissections to recover the exochorion, 4) elaboration of images of it, and 5) the preparation of its description with the necessary diagrams and tabulations. Also, we present the detailed techniques applied in observation and graphic representation, based on the methylene blue staining techniques and those required for the use with the scanning electron microscope (SEM). We compare the result of the standardized techniques with those from macro photography, drawings, and photographs with SEM—all of them found in books with descriptions and images of eggs of the Pieridae. We present a glossary and general aspects of the exochorion in the Pieridae as an Appendix to this article. Standardized techniques show more accurate and extensive character retrieval for systematics. For the scale in which they work, these techniques recovered more information than those present from oviposited eggs, where the exochorionic base is not seen. Also, the descriptions contain detailed data on more structures—which are comparable to each other—than are absent in the references mentioned. We present the recovered characters with the techniques found in the literature as three synthetically supplementary materials.

Newcastle disease (ND) is a pandemic viral disease of poultry. It is highly contagious and causes high morbidity and mortality in affected flocks. The disease is caused by Avian orthoavulavirus 1, commonly known as Newcastle disease virus (NDV) belongs to the family Paramyxoviridae. The virus affects almost 241 species of birds. Based on the pathogenicity, the virus is classified into five pathotypes viz., viscerotropic velogenic, neurotropic velogenic, mesogenic, lentogenic and asymptomatic enteric NDV. The severity of the disease varies with the viral pathotype. Isolation and identification along with pathotyping of the virus provides a basis for understanding the type of virus circulating in the region. In the present study, tissue samples from dead/ ailing birds showing lesions/clinical signs suggestive of ND were collected. They were subjected to virus isolation in embryonated chicken eggs and identified by haemagglutination test and confirmed by haemagglutination inhibition test. Eight NDV isolates were obtained out of 55 tissue samples and were classified into pathotypes by intracerebral pathogenicity index (ICPI) and mean death time (MDT). The ICPI values varied from 0.75 to 1.53 and MDT from 54 h. to 79.2 h. Out of eight isolates, three belonged to velogenic group and five were of mesogenic pathotype. The study revealed the circulation of virulent NDV in Kerala. The pathogenicity tests provide a basis for understanding the epidemiology of ND.

Lingual squamous cell carcinoma is one of the most frequent localization of the oral carcinomas. The tongue neoplasia represents nearly 40% of the oral carcinomas. Recent studies showed an increasing trend of lingual carcinoma in young patients. Several staining tests have been described to early detect the disease. After detection, disease free margins resection will increase the survival rate. This study aims to analyze the methylene blue staining test in achieving disease free resection margins in lingual squamous cell carcinoma.

Csf Leakage

Cerebrospinal fluid rhinorrhea represents drainage of cerebrospinal fluid into the nasal cavity. The first steps in diagnosing CSF rhinorrhea are a thorough history and physical examination of the patient. Other diagnostic procedures are the double ring sign, glucose content of the nasal fluid, Beta-trace protein test or beta 2-transferrin. To establish the exact location of the defect imagistic examinations are necessary. However, the gold standard CSF leakage diagnostic method is an intrathecal injection of fluorescein with the endoscopic identification of the defect. In this paper we analyze a staining test, using Methylene Blue solution, to identify the CSF leak�s location.

ABSTRACT: Three outbreaks of poisoning by Portulaca oleracea were reported in sheep and goats in Northeast Brazil. In the first outbreak, 8 out of 20 sheep were affected and later died. In the second outbreak, three goats and one sheep died out of a flock of 30 animals that included both species. In the third outbreak, two out of 19 sheep were affected, and they recovered after a treatment of 2% methylene blue at a dose of 4 mg/kg body weight. In the first and second outbreaks, the animals ingested P. oleracea after it was cut and offered in feeders. In the third outbreak, the flock was grazing in an area that had been invaded by the plant. To determine the toxicity, P. oleracea was administered experimentally at a dose of 80g/kg of body weight to seven sheep, weighing 19-30 kg. One control sheep received green grass. One to four hours after P. oleracea ingestion, the animals showed clinical signs of poisoning characterized by cyanotic mucous membranes, bloat, ruminal pH of 8-9, pollakiuria, aerophagia, involuntary movements of the upper lip, apathy, tachypnea and tachycardia. Five animals recovered, including one that was treated with 1% methylene blue, and two animals died. During necropsy, the mucous membranes were brownish, and the blood was dark brown. Diphenylamine tests of the plant and of rumen contents were positive for nitrates. Positive results for nitrates were also found in 24 samples of P. oleracea that were collected in different places in the states of Pernambuco and Paraíba. We conclude that P. oleracea accumulates nitrates at toxic levels and may cause poisoning in sheep and goats.

The present research work was undertaken for the characterization of the bacterial pathogens responsible for pneumonia in black Bengal goats. Nasal swab samples (n = 50) were collected from the pneumonic black Bengal goats in Mymensingh and Sirajgonj districts. Samples were inoculated onto nutrient agar, eosin methylene blue (EMB) agar, MacConkey agar, and blood agar media for isolation of bacteria. Identification of bacteria was performed by the Gram's staining method, cultural properties and biochemical tests. Antibiotic sensitivity of bacterial isolates was performed against 11 antimicrobial agents. Pasteurella spp were isolated from 25 cases, and Staphylococcus spp from 13 cases. Mixed infection caused by the Pasteurella spp and Staphylococcus spp. were recorded in 12 cases. Pasteurella spp produced whitish, opaque circular and translucent colonies on nutrient agar, smooth, convex, glistening colonies on EMB agar and no hemolysis on blood agar. Staphylococcus spp have shown gray white or golden yellowish colonies on  nutrient agar. Golden yellow colonies without hemolysis or whitish colonies with hemolysis were also produced by Staphylococcus spp. on the blood agar media. Pasteurella spp were indole positive, MR-VP negative and ferment dextrose, sucrose and mannitol with the production of acid. The Staphylococcus spp were positive to MR-VP, coagulase and catalase reactions, negative to indole test and fermented five basic sugars with acid production. Results of cultural and biochemical tests supported that these two isolates belonged to P. multocida and S. aureus. P. multocida were highly sensitive to ciprofloxacin and resistant to penicillin. S. aureus found to be highly sensitive to erythromycin, tetracycline, enrofloxacin, and norfloxacin and less sensitive to amoxicillin. DOI = http://dx.doi.org/10.3329/bjvm.v9i1.11215Bangl. J. Vet.
