The study was carried out to investigate the associated maggots and bacteria in myiasis affected wound in animals. Total 37 myiasis affected cattle (n=25) and goats (n=12) were examined in this study, of which 21 samples were collected from the Veterinary clinics of Bangladesh Agricultural University (BAU), Mymensingh, and the remaining 16 samples were collected from Upazila Veterinary Hospital, Gouripur, Mymensingh. The maggots were collected from the wounds, and were identified under microscope. For microbial identification, samples (n=10) were collected aseptically by using sterile cotton swab. The samples were allowed to grow in media. Colony and staining characteristics were studied. Traumatic, creeping or migratory myiasis wounds were identified in the examined animals. In this study, subcutaneous wound was mostly recorded, of which 43% (n=9/21) was found at the Veterinary Clinics, BAU, and 44% (n=7/16) was found at the Upazila Veterinary Hospital, Gouripur. The maggots were identified as Chrysomya bezziana, commonly known as Old World screwworm. Occurrence of myiasis due to C. bezziana larvae was recorded as 100%. The associated bacteria were identified as Staphylococcus spp. In conclusion, the myiasis wounds are associated with both Staphylococcus spp. and larvae of C. bezziana. Preventive and control measures against the C. bezziana and Staphylococcus spp. can be undertaken to save the livestock from myiasis in Bangladesh.

Anthrax, caused by Bacillus anthracis is an acute, febrile disease of warm blooded animals including humans. Social norms and poverty in addition to climatic factors such as soil conditions, seasons of year, ambient temperature and rainfall influence the persistence of the B. anthracis and anthrax outbreaks. The present study was designed to reveal the factors influencing the repeated outbreak of anthrax in Bangladesh. Considering the previous outbreaks of anthrax, Sirajganj, Bogra, Kushtia, Tangail and Mymensingh districts of Bangladesh were selected for this study. To elucidate the factors, qualitative data relating to the animal management, knowledge and behavior of the people; and quantitative data relating to soil conditions, ambient temperature and rainfall were acquired, and analyzed critically. Based on the outbreak histories, a year was divided into two seasons, anthrax prone season (May-November) and anthrax dry season (December-April). Anthrax spores could be isolated from 11.67% (n=14/120) of the soil samples collected from the study areas. The present study revealed that poor knowledge, lack of awareness, improper carcass disposal, inadequate vaccination, high Ca content and moisture in the soil along with high ambient temperature and rainfall during the anthrax prone season were the possible influencing factors of repeated outbreaks of anthrax in the study areas. Intensive propaganda to create public awareness of anthrax together with proper vaccination may reduce anthrax outbreaks in Bangladesh.

This case report describes the necropsy findings of two potentially zoonotic parasites infecting the Philippine brown deer (Cervus mariannus) in Leyte Island, Philippines. A female deer aging approximately 5-year was presented for necropsy to the Diagnostic Laboratory at the College of Veterinary Medicine, Visayas State University. Gross pathology was recorded and the selected organs having lesion were collected for histopathological studies. Results showed severe necrotizing lesions in the nasal and palatal areas, infestation of calliphorid maggots, hepatic fibrosis, cholangitis, cholecystitis, lung atelectasis and duodenitis. Heavy ruminal fluke infection was also observed. Two potentially zoonotic parasites namely Fasciola gigantica and Sarcocystis spp. were identified. The Philippine brown deer appears to have a role in transmission and amplification of zoonotic parasites, and can also be threatened by diseases caused by the parasites.

Amit Shukla | Satya Pal Singh | Sakshi Tiwari
The production of animal largely depends on supplying of quality feed and proteinaceous supplement to the animals. Jatropha plant can grow in the barren lands, and are used as a source of biodiesel. Besides, the plant may act as a rich proteinaceous source. However, the antinutritional factors present in the seed and seed oil of the plant may hamper the availability and beneficial use of the plant. Curcin and phorbol esters are the major toxic compounds present in the plant; these toxic compounds cause to produce liver and kidney diseases. Detoxification of these toxic compounds by physical and chemical means converting to less toxic seed cake may serve the purpose of using this plant in future as a replacement of costly protein supplement for animals. Therefore, in modern world, it is recommended to utilize the protein source by neutralizing the antinutritional factors. This mini-review describes the updates on how J. curcas can be utilized as a supplementary source of protein for animals by decreasing its toxicity.

2015
John Palmisano | Michael Deininger
Canisters containing activated charcoal are commonly used in the laboratory setting to collect waste anesthetic gas (WAG). This requires the weighing of the WAG canister after each use and for investigators to maintain an accurate time log of anesthesia duration. A typical rodent anesthesia station may include the use of 3 WAG canisters; one for the anesthesia induction box, one for the operative table, and one for gas monitoring. To simplify the anesthesia breathing circuit, we have developed a “T” connector that replaces the need for having multiple WAG canisters. The “T” connector directs the waste anesthetic from multiple sources; the anesthesia induction box, operative table and gas monitor into a single WAG canister. Use of the “T” connector appears to be a safe, acceptable device that conveniently directs waste gas while improving charcoal adsorption within the canister. In addition, this device may have a positive impact on the environment with a secondary benefit of possible cost savings associated with the purchase and disposal of the hazardous waste contents.

The present study was undertaken to mitigate Salmonella from betel leaf in Mymensingh. A total of 35 betel leaf samples were collected from 2 baroujes and 5 local markets in Mymensingh. The samples were sub-divided into two groups: (i) phosphate buffer solution (PBS) washed, and (ii) grinded sample. There was control and treated (with 1.5% vinegar, sorbitol, and sodium benzoate) sub-groups in both groups. Mitigation of Salmonella was determined by comparing Total Viable Count (TVC) and Total Salmonella Count (TSAC) of control with treated groups. No bacterial growth was observed in the betel leaf samples collected directly from barouj level. At market level, when grinded, there was no growth of bacteria in Plate Count Agar (PCA) and Salmonella- Shigella (SS) or Xylose Lysine De-oxy-chocolate (XLD) in both treated and untreated groups. But when the PBS washed samples were used, the TVC (mean log CFU±SD/mL) of betel leaf ranged from 5.16±0.82 to 5.96±1.11, whereas the TSAC value ranged from 4.87±0.58 to 5.56±1.00 for untreated group. In vinegar, there was no growth, but when treated with sorbitol, the TVC (mean log CFU±SD/mL) value reduced to 5.00±0.54 to 5.66±1.09, and TSAC (mean log CFU±SD/mL) value reduced to 4.28±0.71 to 4.78±0.64. When treated with sodium benzoate, the TVC (mean log CFU±SD/mL) value reduced to 5.06±0.53 to 5.75±1.02, and TSAC (mean log CFU±SD/mL) value reduced to 4.34±0.79 to 4.92±0.64. Data of this study indicates that all the three chemicals were effective in terms of reducing bacterial load but vinegar (1.5%) was found to be the most effective against Salmonella as well as some other bacteria when treated for 10 min.

Leda Maria Costa Pereira | Paulo Ricardo Oliveira Bersano | Maria Denise Lopes
Foi avaliada a influencia do ciclo estral e temperatura de transporte de ovários na maturação in vitro de oócitos caninos. As cadelas foram categorizadas em dois grupos baseados no estagio do ciclo estral – anestro ou diestro. Um ovário por par coletado foi transportado em solução fisiológica 0,9% a 4°C enquanto o outro foi transportado a 37°C. Então, os ovários foram seccionados em PBS para a liberação dos complexos cumulus oocito (COCs). Um total de 345 COCs (n = 186 oocitos obtidos de cadelas em anestro e 159 em diestro) foi cultivado em TCM 199 suplementado com HEPES, piruvato de sódio, cisteina, hormônio folículo estimulante (FSH), gonadotrofina coriônica humana (hCG), estrógeno (E2) e fator de crescimento epidermal (EGF). Apos 72h de maturação, os COCs foram desnudados, fixados e corados para avaliação da maturação nuclear. O teste de Fisher foi utilizado para avaliar as diferenças entre os grupos. O nível de significância adotado foi de 0,05. Os oócitos obtidos de cadelas em diestro transportados a 4°C apresentaram maior frequência de oócitos no estagio de metáfase II (21,1%) que os mantidos na temperatura de 37°C (p < 0,01). De forma similar, houve maior frequência de oócitos nos estágios de metáfase II (11,2%) nos ovários obtidos de cadelas em anestro e transportados a 4°C que nos ovários mantidos a 37°C (p < 0,05). Concluiu-se que a temperatura de transporte influencia os resultados de viabilidade oocitária canina e a maturação in vitro, independentemente do estagio reprodutivo da fêmea.
