Objective: The present study was carried out to evaluate morphometric and histopathological abnormalities during organogenesis in liver, kidney, brain, spinal cord, heart, Lung, digestive tract and spleen in rabbit feti in response to oral administration of Khat prepared from leaves of khat tree (Catha edulis). Materials and methods: The current work was carried out with apparently healthy adult New Zealand rabbits (n=27; 3 males and 24 females) weighing 2.5±0.5 Kg. The female rabbits were divided into four equal groups. Three goups (low, medium and high dose groups) were treated with Khat. The groups were given 3 mL, 6 mL and 12 mL extract/Kg bwt once daily from day 8 to 18 of gestation, respectively. The control group was given distilled water only. All females were slaughtered on day 28 of gestation. Visceral organ were subjected for histopathological examinations. Results: Khat was found to be associated with hepatotoxicity and nephrotoxicity in rabbits. The kidney of feti of treated dams showed subcapsular hemorrhages along with mild vacuolar degeneration of some renal tubular epithelium. Glomeruli were atrophied, and moderate degenerative changes were observed in renal tubular epithelium and hemorrhages between renal tubules. The liver of the feti showed vacuolar degeneration, necrotic hepatitis, congestion of central veins and hepatic sinusoids, pyknotic clumped nuclei, hemorrhages, edema with atrophy of some hepatocytes, and hyperplasia of Megakaryocytic cells. The Khat also harmed the brain causing hemorrhage, edema, degenerative changes, swelling and necrotic changes of some nerve cells as well as supporting cells. The spinal cord was affected showing degeneration of nerve fibers in white matter and some neurons in grey matter. The heart of treated feti showed congestion of epicardial blood vessels and diffuse degeneration of heart muscles. Lung and alimentary tract only showed congestion of blood vessels. Conclusion: Prenatal exposure of Khat in rabbit induces harmful effects in defferent visceral organs including liver, kidney, brain, spinal cord, spleen, intestine, heart and lung.

Objective: This study was conducted to assess the effect of dietary Moringa oleifera leaf (MOL) feed supplementation on serum biochemical parameters of broilers challenged with very virulent infectious bursal disease virus (vvIBDV). Materials and methods: Two hundred and forty day-old Ross 308 hybrid broiler chicks were randomly assigned into four groups (A, B, C and D) of 60 chicks each and raised in deep litter housing. Broiler starter (BS) and broiler finisher (BF) mash were formulated each with 5% MOL included as part of the feed ingredient for broilers in groups A and B while BS and BF for broilers in groups C and D were formulated without MOL. Broilers in groups A, B and C were challenged intraocularly at 35 days of age with with 0.05 mL of a live vvIBDV, while those in group D served as control. Blood was collected from 10 broilers in each group via the wing vein at 35, 38 and 42 days of age to determine their serum biochemical profile. Results: The level of melondialdehyde (MDA) was observed to significantly decrease in groups A and C. There was a significant decrease in the level of AST in group A, B, C and D. The values of ALT significantly decreased in group A, B, C and D. Conclusion: Supplementing broilers feed with MOL neither protect the liver from damage nor prevent lipid peroxidation.

Objectives: This study was conducted to assess the prevalence and characterization of Staphylococcus aureus from chicken and quail eggshells and to study the antibiogram of the isolates. Materials and methods: A total of 300 eggs (220 chicken eggs and 80 quail eggs) were collected from different retail shops and farms in Mymensingh district. Swabs taken from the egg surfaces were cultured on Mannitol Salt Agar for the isolation of S. aureus. Polymerase chain reaction was conducted for confirmatory identification of the bacterial species targeting nuc gene, followed by confirmation of methicillin-resistant S. aureus by targeting the mecA gene. Antibiotic sensitivity test of the isolated bacteria was done against commonly used antibiotics by the disk diffusion method. Results: The prevalence of Staphylococcus spp. and S. aureus in the chicken eggshell surface was 20.45% and 10.45%, respectively. Similarly, the prevalence of Staphylococcus spp. and S. aureus in quail eggshell surface was 16.25% and 5%, respectively. Overall, 27 isolates were identified as S. aureus, of which 23 were from the chicken eggshell surface and four from quail eggshell surface. Among the seven isolates tested, overall four (57.14%) were positive for the nuc gene. On the other hand, the mecA gene could be detected in three (50%) S. aureus out of six oxacillin resistant isolates. The antibiogram study indicated that most of the isolates were resistant to the antibiotics under β-lactam group. Conclusion: The present study concludes that chicken and quail egg surface harbor multidrugresistant bacteria which may cause public health hazards, if these antibiotic-resistant bacteria are transferred to a human.

Objective: Shiga-toxin producing Escherichia coli (STEC) is the most important foodborne bacterial pathogen worldwide and the bovine animals are assumed as a reservoir of this pathogen. The present study was conducted to assess the role of bovine animals as the source of STEC. Materials and methods: To assess the role of bovine animals as the source of STEC, we examined 100 samples (50 rectal swab and 50 beef samples) collected from the local beef slaughterhouses by cultural, morphological, biochemical tests and polymerase chain reaction. Finally, the drug resistance pattern of isolated organisms has been examined. Result: In the preliminary screening by polymerase chain reaction (PCR), E. coli was more prevalent in rectal swab (n=21/50) than beef samples (n=16/50). Among 39 isolated E. coli, 10 isolates were confirmed as STEC (Rectal swab=7, Beef=3) by PCR, where stx2 gene (n=7/10) was predominant than stx1 gene (n=3/10). Remaining 29 isolates did not react to stx primers in PCR. Presence of STEC in beef samples was significantly associated with the fecal contamination at P≤0.1 (0.074818) in Pearsons correlation coefficient method. In addition, most of the isolated STEC strains were resistant to one or more commonly used antimicrobials in the country. Conclusion: The bovine animals and its products could be an important source of multidrug-resistant STEC in the country. [J Adv Vet Anim Res 2018; 5(2.000): 218-225]

Objective: This study aimed to observe the changes in anatomical pathology, histopathology, and histomorphometry of uterine horn in Aceh cattle with repeat breeding (RB). Materials and methods: In this study, five uterine horns were collected from fertile Aceh cattle (N1, N2, N3, N4, and N5) and Aceh cattle with RB (RB1, RB2, RB3, RB4, and RB5). Changes in the anatomical pathology of uterine horn were observed prior to histopathological preparations. The results were analyzed descriptively. Results: The observation of anatomical pathology revealed that the uterus of fertile cattle was yellowish white with horn-like shape consisting of hollow muscles, while RB cattle were reddish-pale. Furthermore, uterine horn swelling with purulent exudate was observed in the uterine horn of RB1 and RB4, while swelling with serous exudates was found in RB2, RB3, and RB5. Thin-walled uterine horn with caruncular atrophy was observed only in RB3. Histopathological observations showed erosion and hyperplasia of endometrial columnar epithelial and uterine glands in RB1, RB2, RB4, and RB5. Atrophy of uterine gland was found in RB3 and edema of caruncular was observed in RB1 and RB4. In addition, hemorrhage and inflammatory cell infiltration (neutrophils, lymphocytes, and macrophages) were found in all RB cattle. Histologically, cow uterus is divided into three layers, endometrium, myometrium, and perimetrium with the uterine gland found in the endometrium. Histomorphometric measurements found that the uterine horn wall (endometrial, myometrial, and perimetrium) of RB cattle were thicker than of fertile Aceh cattle, 208.06 ± 39.90 vs. 187.39 ± 29.09 μm, 400.138 ± 51.96 vs. 277.91 ± 42.88 μm, and 23.59 ± 9.67 vs. 18.53 ± 4.40 μm. However, the endometrial gland diameter of RB cattle is smaller than that of fertile Aceh cattle, 4.04 ± 0.88 vs. 4.99 ± 1.37 μm. Conclusion: The changes in anatomical pathology and histopathology of the uterine horn of Aceh cattle with RB indicate endometritis which caused by subacute and chronic bacterial infections. Endometritis causes disrupted blood circulation, which is characterized by hemorrhage, edema, and thickening of the endometrium, myometrium, and perimetrium, resulting in an increased diameter of the endometrial gland in RB Aceh cattle.
