“…External lesions, such as enlargement of the superficial lymph nodes, including sub-mandibular, parotid, pre-scapular, subiliary, popliteal and supra-mammary lymph nodes, as defined by Baird and Fontaine (2007), Kumar et al (2012) and Williamson (2001) in small ruminants, have not been observed in current studies. However, this study noted the enlargement of the second most affected superficial lymph node called pre-scapular lymph nodes which were in line with the previous reports described by Ali et al (2016) and Anil (2019) in bovine and by Ayers (1977), Fontaine and Baird (2008), Mira et al (2014), Stoops et al (1984), Valli and Parry (1993), Williamson (2001), Yitagesu et al (2020) and Zeru and Kahsay (2014) in shoats, who reported an enlarged superficial lymph node with a diameter of 13 cm. These results may be attributed to the habit of bulls that tend to scratch their shoulders and heads against walls and fences or any hard objects, resulting in a high percentage of superficial pre-scapular lymph node infections because they drain the shoulder region (Fontaine & Baird, 2008;Jubb et al, 2012;Yitagesu et al, 2020;Zeru & Kahsay, 2014).…”

“…CLA is a chronic infectious disease of a wide range of mammalian species in the world, including Ethiopia, characterized by the enlargement of one or more lymph nodes (Ali et al., 2016; Belchior et al., 2009; Braga, 2007; Ruiz et al., 2020). This study reported a single case of CLA out of 30 cattle slaughtered in the Bishoftu municipal abattoir and exhibited an enlargement of the pre‐scapular lymph node to the post‐mortem carcass inspection, which appeared to be consistent with previous reports of Anil (2019) in cattle and Salgado et al. (2011) and Yitagesu et al.…”

“…The transmission of this disease occurs through the release of a large number of bacteria from a ruptured abscess, which spreads over the skin and fleece of infected animals and also the environment.

Background: Caseous lymphadenitis (CLA) is a chronic bacterial infectious disease that affects cattle, shoats, and other domestic and wild ruminants.
Methods:A purposive cross-sectional study was conducted on 30 cattle with enlarged lymph nodes to investigate CLA using cytopathological and bacteriological techniques from cattle slaughtered at Bishoftu municipal abattoir.Results: From a total of 30 cattle subjected to clinical and post-mortem examinations, only one bull was found to be infected with a rare case of CLA in Bishoftu municipal abattoir, Ethiopia. Enlargement of the pre-scapular lymph node was the only clinical finding during ante-mortem inspection of the bull. The gross pathological lesion showed a pre-scapular lymph node with a caseo-necrotic dystrophic calcification that was accompanied by a rough texture and white to grayish hue. Histopathologically, the lymph node was characterized by central liquefactive necrosis that was surrounded by coagulative necrosis containing multiple foci of mineralization, infiltration of polymorphonuclear neutrophils and mononuclear immature fibrosis containing inflammatory cells and also with some sort of a thick layer of mature fibrosis that defines the magnitude of the lesion. Cytologically, multi-lobulated (intact and degenerated) neutrophils, a few reactive lymphocytes, macrophages and some crenated histocytes have been recognized. The bacterial culture of the sample revealed small, white cream, dry, waxy colonies with a narrow area of β-haemolysis. The isolate of the sample was a Grampositive cocci-bacilli that was arranged in a Chinese pattern on Gram staining, and catalase and urease were positive in the biochemical analysis of this organism, which was able to ferment glucose and maltose but not trehalose and xylose.
Conclusions:The present investigation indicated that CLA was prevalent as sporadic cases among cattle slaughtered in Bishoftu municipal abattoir. Thus, effective preventive and control measures, such as good sanitation and hygiene, should be followed during meat inspection.

“…This is due to the failure of the prolapsed mass to attain the normal size. There are two approaches in retention of the prolapsed mass; one approach is conservative and involves application of rope truss at the vulva (Kumbhar et al, 2009), while the other is invasive involving the suture of the vulva (Prasad and Rajesh, 2014;Bhoi and Parekar, 2009). The method can be selected based on the intensity of contractions, size of prolapsed mass and status of animal.…”
Prolapse is a common ailment associated with parturition in cattle and buffaloes. An eight-year-old, non-descript buffalo with the history of aggressive assistance during parturition was presented at farmers doorstep for third degree complete uterine prolapse. The prolapsed mass haemorrhagic and soiled, the mass was cleaned maintaining all aseptic measures. Animal was restrained and using the three-step management reduction, reposition and retention of the prolapsed mass was undertaken. The blood parameters indicated anaemia, neutrophilia, and eosinophilia, while the serum profile indicated hypocalcaemia. The case was managed rationally by rehydration, supplementation of energy and calcium. The infection and trauma of uterus was managed with antibiotic therapy, analgesics and antiallergics. The animal recovered uneventfully without a relapse of the uterine prolapse.
Fetal mummification is uncommon in small ruminants like goat and sheep. The twin mummification of fetuses confirmed by history, a clinical sign, ultrasonographical and per-vaginal examination in five year old Surti doe of fourth parity. The case was successfully managed therapeutically using intravenous administration of 3.0 ml Dexamethasone®, 20IU- Oxytocin®, 500ml-Normal saline and 30ml-Calcium magnesium borogluconate, whereas 5ml-Valethamate bromide (Epidosin®) was given intramuscularly. The goat resumed to normal appetite and appearing active and alert within a week post treatment.
