“…Where possible, gynaecological evaluations in live animals should proceed with proper history, clinical and laboratory examination in order to determine specific aetiologies and generate useful data for effective diagnosis of genital disorders. This approach coupled with assessment of serum hormone profiles could hasten decisions for or against remedial measures to be deployed in the management of reproducti ve disturbances (Ferreira et al, 2008). For example, it has been suggested that under oestrogenic influence (follicular phase), the uterus is more resistant to bacterial invasion than during the prevalence of high progesterone (luteal phase) in animals (Adams, 1975;Amin et al, 1996).…”

An abattoir survey was undertaken to investigate genital bacterial infections of ewes in tropical arid zone of Nigeria. Vaginal and uterine samples were collected and cultured using standard bacteriological techniques. The results of the study showed that the isolates were Escherichia coli (32%), Staphylococcus spp (26%), Klebsiella spp (16%), Pseudomonas (15%) and Proteus (11%); wherein E coli and S aureus were the most common bacterial isolates. The bacterial population in the vagina (64%) was si gnificantly (p<0.05) higher than that in the uterus (34%). The antibiotic susceptibility test revealed that E. coli was highly susceptible (100%) to Amoxycillin, Ampicillin, Amoxycillin-clavulanate and Pefloxacin, whereas low susceptibility was observed against Ciprofloxacin and Ofloxacin (10 and 22% respectively). S. aureus showed 100% susceptibility to Amoxycillin-clavulanate, Gentamicin, Nalidixic acid and Pefloxacin, whereas susceptibility against Streptomycin, Amoxycillin, Ciprofloxacin and Ofloxacin was in declining order (46, 33, 30 and 20% respectively). The potentials of these microbes for producing pathogenicity in genital tract of ewes is likely to be high in Nigeria. Therapeutic use of these antimicrobial agents will help to reduce infectious reproductive diseases in ewes, though in-vivo trials are further required for establishing their efficacy in controlling genital infections in ruminants.

“…The bull-cow interaction usually ranges from 45 to 90 days, although sometimes it lasts 6 months or it may also be permanent. Few reports on RBC exist in beef cattle (Maurer & Echternkamp, 1985;Ferreira et al, 2008).…”

“…The uterine adenomyosis was observed in heifers/cows culled at slaughterhouses by Monteiro et al (2003), who observed the occurrence of 26.7%, by Moreira et al (2006) founded 70%, and by Ferreira et al (2008) where were observed 53% of adenomyosis in repeat breeder beef cows. These percentages are conflicting; however the adenomyosis is not an unusual finding in cows, as reported in the classical literature (Jubb andKennedy 1987, McEntee 1990), and a scarcity of records of this dystrophy in cows may be justified to be a myometrial injury that does not make up endometrial biopsy samples.…”

Differential immunohistochemical expression of matrix metalloproteinase-2 and tissue inhibitor of metalloproteinase-2 in cow uteri with adenomyosis during follicular phase

The present investigation was intended to show a different immunohistochemical profile of matrix metalloproteinase-2 and Tissue inhibitor metalloproteinase-2 in bovine uteri with adenomyosis during follicular phase. Uterine samples of 32 cows in reproductive age were taken from the medial third of one of the uterine horns and grouped according to the adenomyosis degree (superficial and deep). Tissue sections (4 μm) were incubated overnight at 4°C with monoclonal antibody for matrix metalloproteinase-2 and Tissue inhibitor metalloproteinase-2. Staining intensities were evaluated in the luminal epithelium, ectopic and dystopic endometrial tissue (stroma, capillaries and glands), endometrial-myometrial border, myometrium, myometrial vessels (middle tunic and endothelium). The matrix metalloproteinase-2 expression was higher for deep adenomyosis samples, showing a differential mean reactivity in superficial endometrium, myometrial vessels, myometrium adjacent to adenomyotic focus and endometrial-myometrial border (P < 0.05). Moreover, matrix metalloproteinase-2 expression was higher in deep adenomyosis samples than that of Tissue inhibitor metalloproteinase-2 in almost all uterine structures analyzed (except for the endometrial and myometrial vessels and endometrial-myometrial border). The opposite was observed in the follicular phase, for both normal specimens and with superficial adenomyosis, where Tissue inhibitor metalloproteinase-2 expression was higher than that of matrix metalloproteinase-2. In conclusion, a differential pattern of matrix metalloproteinase-2 and Tissue inhibitor metalloproteinase-2 was observed in cow uteri with adenomyosis.

Relationship between clinical and postmortem evaluation in repeat breeder beef cows

Abstract: The objective of this study was to investigate the causes of the repeat breeder syndrome comparing clinical signs and postmortem findings in beef cows. The identification of factors affecting the reproductive tract can support decisions as to whether treatment of repeat breeder cows is
