(Chittagong Veterinary and Animal Sciences University Chittagong – 4225, Bangladesh, 2015-01) Sarma, Sabuj
A study was conducted to estimate the prevalence’s of different bacterial and viral diseases in poultry of Namakkal region, Tamil Nadu. All information’s are collected during my internship placement(16th June to 2 July, 2014) in Poultry Disease Diagnosis & Survillance Laboratory(PDDSL),VC&RI, Namakkal. Clinical history was taken from the owner of the poultry farm and local students. Post mortem of a total of 210 dead birds were done for the diagnosis purpose. Different poultry species included into the study was broilers, layers, pegion, duck etc. Among 210 birds, highest 80 birds (38%) were affected with infectious bursal disease (IBD), followed by heat stress 13%, new castle disease (ND) 11%, Coccidiosis 6% and Salmonellosis 6%. IBD in layer was found significantly associated with the age of the bird and flock size of the farm. Chicks aged between 16-23 days and flock size between 1175 – 1460 was found to be the most susceptible group having IBD. Diseases found to be highly prevalent in the study area are also economically important and cause significant damage to the farmers. Therefore, it is necessary to conduct effective control measures to reduce the prevalence of these diseases. To design and conduct an effective control measure, need to find out the potential risk factors of the diseases hence need to conduct an extensive study.
A case report on alveolar rhabdomyosarcoma in an indigenous dog
(Chattogram Veterinary & Animal Sciences University, Khulshi,Chattogram, 2023-11) AKTER, FARJANA
A 12 years-old, male indigenous dog was presented to Shahedul Alam Qaderi Teaching Veterinary Hospital (SAQTVH) in Chattogram, Bangladesh with a large tumor on its right front leg. The histopathological findings of the tumor revealed as alveolar rhabdomyosarcoma (ARMS). The tumor was surgically removed from the dog, while there had been no recurrence for five months, the patient died five months post-operatively. The cause of the death would be metastasis which could not be confirmed due to lack of follow up. A histopathological study showed poorly differentiated neoplastic mononuclear cells forming nests in an alveolar pattern. This is the first incidence of ARMS in an indigenous dog in Bangladesh. Despite the limited resources prevented myogenin staining for diagnostic confirmation, the well-contained, defined appearance of the tumor supports the diagnosis of ARMS. This report highlights the challenges in diagnosing and treating ARMS in indigenous dogs and emphasizes the need for further research and diagnostic markers to improve detection and management.
A case Report on Constipation in Persian Cat
(Chattogram Veterinary & Animal |Sciences University, 2022-11) Akhter, Sanu
The term "constipation" refers to the irregular or absent passage of excrement via the colon and rectum. Cat constipation can have a variety of known causes, and the clinician's ability to identify the correct etiology in each case will determine how the condition is managed. The doctor may have to decide between surgical and therapeutic approaches to such cases. Numerous factors, including the identification of an underlying cause, the colon's ability to operate, and the results of medical treatment, will affect this decision.A two-year-old male Persian cat weighing about 4 kg was presented with a clinical history of weakness, loss of appetite, abdominal pain, decreased to absent defecation, hyporexia, small, dry feces, abdominal straining, hind-limb paresis, vocalization during defecation, vomiting, and lethargy, which were identified during the clinical examination. After confirmation of constipation by an X-ray report, the cat was treated with lactulose, simethicone, and glycerol, followed by an enema with avolac solution. After 7 days of continuous treatment, the cat was completely recovered.

(Chittagong Veterinary and Animal Sciences University, Khulshi-Ctg, 2014-03) Biswas, Shankar
A comprehensive study was conducted in a cattle that was suffering from acidosis after feeding of large amount of grain and cooked rice. My study on ruminal acidosis in cattle’’ was conducted during internship program at Madras Veterinary College, Chennai, india. Tentative diagnosis of the case was performed from relevant history, clinical signs, clinical examination of color, odor and consistency of rumen fluid and rumen microflora movements. Confirmation diagnosis was performed by measuring the rumen fluid and blood pH. The predisposing factors of ruminal acidosis were from feeding of cooked rice, rice gruel. The mean temperature, rumen motility, rumen fluid pH and serum pH of the affected cattle 101.5℉, 5.6, 5.5 and 7.2 respectively. The most effective treatment of acidosis in cattle was observed from the use of ruminal alkalizer (magnesium hydroxide, sodium bicarbonate ,5% sodium bicarbonate, some antibiotics potentiated Sulphonamides and Tetracycline along with fluid therapy. This study suggests that carbohydrate in dairy feed should be cautiously in dairy farm to prevent ruminal acidosis

(Faculty of Veterinary Medicine, Chattogram Veterinary and Animal Sciences University, Khulshi, Chattogram-4225, Bangladesh, 2024-12) Mia, Milon
Dermatophytosis is one of the significant concerns in sheep, impacting animal health, farm productivity, and the economy. As a zoonotic disease, it also poses health risks to humans, making effective management essential both for livestock and human health. Common clinical signs are typically well-demarcated and exhibit a scaly, crusted surface as well as alopecia. Affected skin often becomes thickened and roughened with pronounced scaly and crusty texture while pruritus is not prominent. A one-and-a-half-year-old, local non-descriptive pregnant (2.2 months) sheep was presented to Shahedul Alam Quadery Teaching Veterinary Hospital (SAQTVH), CVASU with complaint of continuous mild to severe alopecia. After careful examination with Wood's lamp and direct visual inspection, lesions were primarily suspected as dermatophytosis. For supporting the initial diagnosis, blood samples were collected and parameters like Hemoglobin, PCV, TEC, TLC, DLC of affected sheep were investigated. For further confirmation, skin scrapings were collected to perform tests like direct microscopic examination using 10% KOH, Gram Staining and fungal culture on Sabouraud Dextrose Agar (SDA). Presence of hyphae and growth of fungi confirmed that, the sheep was affected with dermatophytes Trichophyton sp. As the sheep was pregnant, pregnancy safe antifungals were given orally as main drug. For supportive care the zinc supplements as well as vitamin AD3 were included. After a regular monitoring and follow-up for about one month, the sheep had an excellent recovery without any complications.
A Case Report on Diagnosis and Surgical Management of Squamous Cell Carcinoma in a Local Dog
(Faculty of Veterinary Medicine, Chattogram Veterinary and Animal Sciences University, Khulshi, Chattogram-4225, Bangladesh, 2024-12) Zaman, Shakib
Squamous cell carcinoma (SCC) is a malignant tumor of squamous epithelial cells that is frequently studied in veterinary medicine, particularly in dogs, due to their higher cancer incidence and similarities to human oncology. SCC is one of the most common carcinomas in domestic animals, typically affecting light-colored or sun-exposed areas such as the legs, nasal planum, and scrotum. This report describes a nine-year-old male dog with a 10 cm prepubic swelling, suspected of being a tumor. Following sedation and anesthesia, the tumor was surgically excised, weighing 200 g, and submitted for histopathological examination. Microscopic analysis confirmed the diagnosis of SCC, showing characteristic proliferating squamous cell nests, keratin pearls, fibrous stroma, angiogenesis, and inflammatory cells. The neoplastic cells exhibited hyperchromatic nuclei, a high nuclear-to-cytoplasmic ratio, and finger-like projections at cell junctions. Postsurgery, the dog recovered well, with normal behavior and health parameters, and wound healing occurred without complications. This case underscores the significance of early detection and surgical intervention in SCC, providing valuable insights into both veterinary and human oncology through comparative cancer biology.

Listeriosis is a sporadic bacterial infection that affects a wide range of animals, including people and birds. Case of listeriosis found in goats as well. It is seen worldwide, more frequently in temperate and colder climates. There is a high incidence of intestinal carriers. Encephalitis or meningoencephalitis in adult ruminants is the most frequently recognized form. In this study a Jummuna pari male goat was tentatively diagnosed as having listeriosis based on presenting clinical signs. The patient was successfully treated with crystalline penicillin and dexamethasone in the S.A. Q. Teaching veterinary Hospital, CVASU
A Case Report on FMD in a Holstein Friesian Bull: Necropsy and Histopathological Insights
(Faculty of Veterinary Medicine, Chattogram Veterinary and Animal Sciences University, Khulshi, Chattogram-4225, Bangladesh, 2024-12) Rabina, Sultana Lamhi
Foot-and-mouth disease (FMD) is an economically significant diseases affecting cattle and other ruminants with distinct clinical manifestations and pathophysiological outcomes. In adult cattle, FMD typically presents with mucosal and dermal lesions. In calves, myocarditis is the predominant cause of mortality which is rare in adult cattle. This case report presents an unusual fatal manifestation of FMD with severe myocardial and systemic lesions in a 3-year-old Holstein Friesian Bull from CODEK Farm, Karnaphuli, Chattogram, Bangladesh, which had been treated for Bovine Ephemeral fever (BEF) four months prior to death. The bull exhibited acute anorexia and fever without external skin lesions prior to death. Necropsy revealed notable gross lesions, including ulcerative lesions in the tongue, hemorrhagic and emphysematous lungs, petechial hemorrhages and necrosis in the heart muscle, enlarged friable liver, hemorrhagic mesenteric lymph nodes, and intestines. Histopathological analysis revealed severe myocarditis with coagulative necrosis of myocardial fibers, interstitial infiltration of lymphocytes, plasma cells, and histiocytes, along with a tigroid heart appearance. Liver histology demonstrated fatty degeneration, central vein congestion, hepatic cord disintegration, and neutrophilic infiltration. Lung tissue showed marked congestion, hemorrhage, necrosis of bronchiolar epithelium, and fibrous tissue proliferation. Brain histology revealed lymphocytic meningitis, glial cell proliferation, and neuronal degeneration, while intestinal mucosa displayed hemorrhagic changes and goblet cell proliferation. The presence of myocardial lesions in this adult cow, a feature more commonly associated with FMD in calves, suggests a potential correlation between prior BEF infection and heightened susceptibility to myocardial damage. BEF’s transient immunosuppressive effects might have predisposed the animal to systemic complications during subsequent FMD infection. This case report underscores the importance of considering prior disease history, particularly immunosuppressive conditions like BEF and other related infections, in understanding mortality risks in FMD outbreaks in adult cattle particularly those involving myocardial lesions. Therefore, robust vaccination strategies, and biosecurity measures are recommended to mitigate such outcomes.
A case report on histopathology of squamous cell carcinoma in the pinna of a goat
(Faculty of Veterinary Medicine, Chattogram Veterinary and Animal Sciences University, Khulshi, Chattogram-4225, Bangladesh, 2024-12) Khanom, Suraiya
Squamous cell carcinoma (SCC) is a malignant neoplasm that originates from the squamous epithelium and is found in various species, including goats, where it is the most common epithelial neoplasm. However, diagnosing SCC, particularly in rare forms like the adenoid variant in the pinna, remains difficult due to the scarcity of instances and the economic consideration of slaughtering the affected goats. This case report describes the diagnosis of an invasive adenoid variant of SCC in the right pinna of a two-year-old male goat which was brought in Shahedul Alam Quaderi Teaching Veterinary Hospital (SAQTVH) in Chattogram, Bangladesh. After developing over the course of three months, the mass was surgically removed and sent for histopathological analysis which revealed well-differentiated anaplastic squamous cells, characterized by large hyperchromatic nuclei, mild pleomorphism, and keratin pearl formation. The tumor cells were arranged in islands with pseudo-glandular patterns, indicative of the adenoid subtype. These findings confirm the diagnosis of grade-1 SCC, adenoid type. This report highlights the histopathological characteristics for accurate diagnosis and adds to the limited literature on SCC in goats.

(Chattogram Veterinary & Animal Sciences University, Khulshi,Chattogram, 2023-11) Moniruzzaman, Muhammad
Myiasis, caused by dipteran fly larvae infestation in living tissues, poses a significant threat to ruminant health globally. This study investigates the treatment efficacy of various protocols for myiasis in cattle, goats, and sheep. The research, conducted over three months at Daganbhuiyan upazila veterinary hospital in the Feni district, the S.A. Quadery teaching veterinary hospital (SAQTVH), and the Hathajari upazila veterinary hospital in the Chittagong district of Bangladesh, focused on 10 affected ruminants. Diagnostic evaluation involved wound history, inspection, odor, exudation, and maggot presence. Three treatment protocols were applied and evaluated based on wound healing, using turpentine oil, povidone iodine, ivermectin, and antibiotics. A comprehensive analysis of wound area and depth reduction indicated the superior effectiveness of a treatment protocol involving turpentine oil and ivermectin, yielding a 97% healing rate in wound depth and 95% in wound area by day 18. The study showcases the superiority of this approach, removing maggots, administering ivermectin, antibiotics, antihistamines, anti-inflammatory drugs, fly repellents, and topical antibiotics. Myiasis incidents were primarily found in the vulva, shoulder, and thigh regions, consistent with previous research. The findings also confirm the commonality of myiasis in cattle and goats compared to other animal species. The study's outcome suggests the effectiveness of the proposed treatment strategy in field conditions, particularly in promoting rapid and extensive wound healing in ruminants affected by myiasis. This research serves as a valuable contribution to the understanding and management of myiasis in veterinary medicine.

A 4.5-years-old Kangayam cow was admitted to the Large Animal Clinics, Veterinary College and Research Institute, Namakkal, India. According to the owner’s complain, the cow had a problem during standing position for several days with difficulty in urination and frequent sanguineous discharge from the vagina. The cow was non-pregnant, showing no estrus sign and the last calving was one-and-half-years back. Appetite was normal and the general physical examination revealed no other abnormalities. Clinical examination revealed a tumor like mass attached to the lateral side of vagina, which was confirmed by ultrasonography. After performing the high epidural anesthesia with lidocaine (5mg/Kg) the mass was surgically removed. The dimensions of the mass were 8.5× 4 × 5.4 cm and 100gm in weight. Macroscopically, it was relatively well circumscribed with lobulated and ulcerated surface like cauliflower appearance. After cross section, the mass was homogenously creamy in color with foci of necrosis or hemorrhage. Microscopically, the growth was composed of spindle-shaped fibroblastic tumor that formed interlacing and intersecting bundles. The neoplastic cells showed pleomorphism, karyomegaly with slight nuclear hyperchromatism. On the basis of site, biological behavior, macroscopic and microscopic characteristics, the mass was diagnosed as a well-differentiated fibrosarcoma. A combined drug of penicillin-streptomycin at a dose rate of 30,000 IU/kg body weight for the penicillin and 10 mg/kg body weight for streptomycin was administrated parenterally for 5 days postoperatively. Meloxicam and Pheniramine Maleate were given as NSAID and antihistamine respectively at the rate of 0.5mg/Kg body weight parenterally for 5 days. The cow was fully recovered after 2 weeks of surgery and there was no recurrence found after 2 months of follow up observation.
