“…In one study, for instance, endometritis was recognized in up to 40% of the postpartum cows by vaginoscopic examination (De Kruif, Gunnink, & Bois, ). In another study, wherein the method of diagnosis was similar to the present, the incidence of endometritis was 35.5% (Derakhshandeh, Aghamiri, Ahmadi, & Mirzaei, ). Because there is no consistent definition or diagnostic consensus regarding CE, the incidence is different in various studies.…”

Contents The objective of this study was to compare the reproductive performance of cows affected by clinical endometritis (CE) following treatment with an intrauterine infusion of 50% dextrose solutions (DEX) and liquid paraffin (LP) as alternative therapies with routine treatments including PGF2α injection and intrauterine infusion of oxytetracycline (OTC). Moreover, the reproductive indices of cows treated with endometritis were compared with those of healthy ones. At postpartum reproductive tract examination (28–35 DIM) in one Iranian dairy farm, cows with CE without any selection were assigned to four groups: (a) OTC, a common treatment in Iran, was administered (5 g) to 396 cows, (b) PGF2α (PG) was injected to 496 cows, (c) dextrose solution (DEX): intrauterine infusion of 50% dextrose solution (200 ml) was done in 427 cows, and (d) liquid paraffin (LP) was administered (100 ml) to 423 cows via intrauterine route. We further assigned 2,233 clinically healthy cows to the control group. The incidence of endometritis was 41.6% in this study. Based on the results of reproductive indices including median days to first AI, days open (DO), first service conception rate, conception rate in 2nd and 3rd services, conception rate in all three services, pregnancy rate < 100 days and pregnancy rate < 200 days, except for median days to first AI in other reproductive indexes, reproductive performance was significantly lower in LP group compared with the healthy cows and other treatment groups (p < 0.05). Except for the first service conception rate and proportion of cows pregnant before 100 days in milk (DIM), there existed no significant difference between the DEX group and the control as far as reproductive performance is concerned (p ≥ 0.05). The first service conception rate was recognizably lower in DEX group compared with OTC and PG (p < 0.05). In conclusion, the use of a non‐antibiotic special solution of dextrose 50% is a good alternative to antibiotic agents concerning the treatment of CE in dairy cows.

“…In the study conducted by [26], Figure 1 illustrates the utilization of multiplex PCR to detect pathogenic bacteria. Furthermore, Derakhshandeh et al reported the presence of fungi and yeast in uterine samples from cows with endometritis [27]. Similar findings were reported in studies involving repeat breeder cows by [28,29].…”

“…The presence of multidrug resistance in species such as Trueperella pyogenes and E. coli [24,86] and the occurrence of antibiotic residues in milk after intrauterine infusion of oxytetracycline (OTC) [87,88] have raised concerns. It has been observed that intrauterine infusion of antibiotics like OTC may increase the incidence of mycotic endometritis [27].…”

Subclinical Endometritis (SCE) is a postpartum uterine disease that is characterized by inflammation of the uterus without any apparent clinical signs. This condition, despite lacking overt symptoms, has a significant impact on reproductive performance by decreasing pregnancy rates following the first insemination and prolonging the median days open. Risk factors for metritis include the metabolic status of the cow during the prepartum period and issues occurring at or after parturition, such as dystocia (difficult calving) and retained placenta. Elevated concentrations of haptoglobin during the postpartum period have been associated with metritis, cytological endometritis, and purulent vaginal discharge. Subclinical endometritis is a major contributor to the repeat breeder syndrome of bovine subfertility. Treatment of endometritis can cause the production of biofilm in the uterus. Biofilms inherently possess resistance to antibiotics as well as to cellular and humoral immune defenses. Treatment of subclinical endometritis is usually performed as clinical endometritis. Antibiotic infusion is a routine treatment method in dairy farms. But the use of alternative treatments such as hypertonic dextrose and hyperimmune serum mayhelp to improve treatment results. Management of pre- and postpartum periods of dairy cows is the best method for the control of subclinical endometritis.

Bacterial and fungal diseases, such as mycotic endometritis and abortion, are one of the causes of reproductive diseases in Bali cattle. Earlier studies on bovine uterine microflora have mainly focused on bacteria; however, the presence of fungi has yet to be discussed in detail. This study aimed to provide data on the prevalence and identification of fungi by using morphological methods. The samples were vaginal swabs obtained from 22 healthy female Bali cattle from various locations in Bali, Indonesia. For isolation, vaginal swabs were cultured on Sabouraud's dextrose agar (SDA) medium and identification was performed macroscopically by observing colony growth and microscopically using the tape smear method stained with Methylene Blue stain. The results showed that 32 fungi belonging to seven genera were isolated from 22 Bali cows. The prevalence rates of Aspergillus, Fusarium, Cladosporium, Curvularia, and Candida, Mucor, and Penicillium spp. were 41, 25, 19, 6, and 3%, respectively. These data add important information to the literature on the fungal microbiota in healthy Bali cows.
