A study on the pathological lesions of oviducts of buffaloes diagnosed at postmortem

Abstract

The aims of this study were to study the prevalence of oviduct abnormalities of buffaloes, investigate bacteria accompanying hydrosalpinx, pyosalpinx and salpingitis. In addition, the study was designed to investigate the correlation between bacterial infection of the uterus and oviduct lesions in buffaloes. Bacteriological examinations were performed on hydrosalpinx, pyosalpinx and salpingitis. Hydrosalpinx was found in 28 (6.9%) cases of which 20 (71.4%) were found unilaterally and 8 (28.6%) bilaterally. Pyosalpinx was recorded in 12 (2.9%). Three cases (0.7%) of oviducts filled with blood were recorded. Obstruction of oviducts was recorded in 5 (1.2%). Adhesions between mesosalpinx and perisalpingeal tissues were observed in 7 (1.7) cases. One case of double oviduct was found in the left side of the tract examined. The most prevalent bacteria recovered from hydrosalpinx were Corynebacterium hemolyticum and Actinomyces bovis, 42.8% and 28.6%, respectively. No correlation was noticed between bacteria isolated from the uterus and hydrosalpinx. The most prevalent bacteria recovered from pyosalpinx were Escherichia coli, Archanobacterium pyogenes and Staphylococcus aureus, 33.3%, 26.7% and 16.7%, respectively. Higher rates of leukocyte infiltration (P < 0.01) were observed in the uterine discharge and pyosalpinx than hydrosalpinx. In a conclusion, the current study disclosed that oviductal lesions seem to be an important problem in buffalo cows. In addition, there is no correlation between bacteria isolated from uterus and hydrosalpinx. There is a high correlation between bacteria isolated from uterus and pyosalpinx and salpingitis. The occurrence of pyosalpinx and salpingitis is mainly due to bacterial infection. Bacterial isolates from pyosalpinx and salpingitis might be related to ascending infection from the uterus.

Salpingitis Impairs Bovine Tubal Function and Sperm-Oviduct Interaction

“…Common ascending inflammatory conditions reported in cows are vulvovaginitis 15 , cervicitis 16 , endometritis 17 , salpingitis 18 and perioophoritis 19 . Salpingitis 20 and endometritis 21 have been reported as the most common bovine genital inflammatory disorder. They are characterized by increased vascularization and secretion as well as marked infiltration of the tubal and/or endometrial tissue with neutrophils and plasma cells 22,23 .…”

“…In general, laparoscopy is the gold standard to diagnose and confirm the presence of acute salpingitis 45,46 . Salpingitis often causes tubal occlusion and hydrosalpinx 20,21,59 which might result in ectopic pregnancy 60 .…”

Prevalence of various pathological conditions in female buffaloes (Bubalus bubalis)

“…Azawi [67] reported hydrosalpinx was found in 28 (6.9%) cases of which 20 (71.4%) were found unilaterally and 8 (28.6%) bilaterally. Histological examination of these two tubes confirms this diagnosis.…”

Comparative Genome Analysis of 19 Trueperella pyogenes Strains Originating from Different Animal Species Reveal a Genetically Diverse Open Pan-Genome

“…In this comparative genomics study of T. pyogenes strains from all over the world, we have also included the first Indian draft genome sequence of T. pyogenes species (Bu5 strain), which was isolated from wound infections of water buffalo (Bubalus bubalis). Notably, infections due to T. pyogenes in water buffalo have been reported from Mediterranean and Middle East countries [16][17][18]. In India, cases of T. pyogenes infection have been reported from small ruminants [19]; however, reports from buffaloes in India have been elusive.…”
