“…The urine samples were collected by spontaneous urination and, following the recommendation of Polo et al (2013), the first urine of the morning was used, before feeding, which happened approximately at 7 A.M. All the sows had their vulvae cleaned and, in all collections, the first spurts of urine were discarded (MAZZUTI et al, 2013b;MOURA et al, 2018).…”

“…According to Merlini;Merlini (2011), the impact of pig farming on the world economy requires production to be directed to industrial scale, requiring the control of diseases that affect economic output, including urinary infection (UI). It is highly prevalent in the current production systems, causing economic losses due to predisposition to reproductive failure, leading to an increase in the elimination of reproductive females and in the replacement rates (MAZUTTI et al, 2013a;RITTERBUSCH et al, 2014;MOURA et al, 2018). Because of this, many authors have studied the influence of periparturient diseases in the reproductive performance of sows (PORTO et al, 2004;RUEDA LÓPEZ, 2008;BORDIN;GOMES;BUENO, 2012;BELLINO et al, 2013;VENANCIO et al, 2017).…”

The impact of pig farming on the worldwide economy causes production to be directed at an industrial scale, requiring the control of diseases that affect economic performance. Urinary infection (UI), for example, has a high prevalence in current production systems, causing economic losses due to the predisposition to reproductive failures, leading to an increase in disposal of sows and replacement rates. In this context, the objective of this work was to evaluate the prevalence of urinary tract infection (UTI) and possible changes in the urine sediment examination of pregnant sows to survey changes compatible with inflammation of the lower urinary tract. The samples were collected, randomly, from 43 sows of commercial genetic lineage, in different stages of gestation, and that belonged to a pig farm located in Guapimirim-RJ. The pig farm’s herd consisted of 200 sows, 90 of which were in the gestation phase. The samples were collected by spontaneous urination, using the first morning urine, before feeding, which happened around 7 am. The presence of UTI was identified in 12 of the 43 sows analyzed, with 21.5% of the herd being evaluated. A prevalence of 27.9% was observed with animals showing compatible UTI changes. This data was considered severe. The urine sediment examination is the best way to diagnose UTI with sedimentcopy being the most conclusive part. Despite this, it is necessary to relate the laboratory data with the zootechnical management used, as well as the environmental conditions.

“…The prevalence of UTI which was estimated in live sows [13][14][15][16] as well as at abattoirs [3,12,17], by either reagent strip tests, urine culture or histopathology, vary considerably from 15.8 [15] to 58% [16]. There are many reasonable explanations for this wide variation in estimates which challenge the comparability among study results; the most important being the different case definitions, and the different parity structure of the studied sow populations.…”

Urinary tract infections in culled sows from Greek herds: prevalence and associations between findings of histopathology, bacteriology and urinalysis

Background Urinary tract infections (UTI) of sows characterized by cystitis, which may progress to ureteritis and pyelonephritis, can affect their productivity, longevity and welfare. In this study, we determined the prevalence of UTI by histopathology and bacteriology. Furthermore, we investigated possible associations between histologically confirmed cystitis and the results of urinalysis and urine cultures in culled sows from three farrow-to-finish herds in Greece. Materials and methods One hundred eighty-five routinely culled sows were included in the study. Their urinary bladder was collected from abattoirs and subjected to histopathology. Furthermore, urinalysis and urine cultures were performed on urine samples aseptically collected from the bladders. Results Histologically confirmed cystitis was evident in 85/185 (45.94%) culled sows. Among those, 44 (51.76%) suffered from acute and 41 (48.24%) from chronic inflammation. The majority of positive urine cultures were due to colonization of the urinary tract with E.coli, which accounted for 55.81% of the total cases, followed by Staphylococcus spp. which accounted for 18.60% of detected infections. Evidence of cystitis was associated with bacteriuria and sows with bacteriuria were 2.30 (P = 0.03, 95% CI: 1.10–4.83) times more likely to have histologically confirmed cystitis compared to sows with negative urine cultures. Bacteriuria was associated with proteinuria (P < 0.01, OR = 9.72, 2.63–35.88), increased urine pH (P < 0.01, 3.40, 1.10–10.56) and presence of sediment (P < 0.01, 6.00, 1.50–23.76) in urine. Sows with proteinuria had 9.72 (P < 0.01, 2.63–35.88) times higher odds of bacteriuria than those without. Histologically defined cystitis was associated with proteinuria (P < 0.01, 2.03–13.20) and decreased urine pH (P < 0.01, 0.13–0.72). Sows with proteinuria were 5.18 (P < 0.01, 2.03–13.2) times more likely to have histological lesions consistent with cystitis, than those without. For one unit increase in pH, it was 3.20 (P = 0.006, 1.39–7.69) times less likely for a sow to have chronic or acute cystitis compared to absence of cystitis. Conclusion In the studied population, UTI affected almost one out of two culled sows. Bacteriuria, which was more common among sows with UTI than those without, was mainly ascribed to members of the intestinal and environmental bacteria. Proteinuria and the existence of urine sediment which were associated with UTI, could be used as proxy traits for UTI in live sows.

“…A European report indicated that UTI affects from 22% to 40% of sows (Martineau & Almond, 2008). This rate ranges from 29% to 41% of sows in Brazil (Moura et al, 2018;Alberton et al, 2000).…”

Urinary tract infection (UTI) is a common disease in sows, it influences their yield and can also affect piglets. There is a small number of studies in the literature reporting close correlation between UTI in sows and disease development or reduced performance in piglets. Therefore, the aim of the present study is to test whether UTI in pregnancy influences disease development and the growth performance of suckling piglets. Healthy sows, presenting parity 1 to 4, were divided into two groups: UTI (+) (36 sows with UTI) and UTI (-) (36 sows without UTI). After delivery, piglets were monitored for diarrhea, omphalitis, arthritis and facial lesions. Average weaning weight (AWW) was calculated to measure growth performance. There was no difference in diarrhea and omphalitis between groups. However, parity 3 sows and all-parity analyses showed higher frequency of piglets with arthritis and facial lesions. The UTI (+) group showed lower AWW than the UTI (-) group in parity 4 sows and in all-parity analyses applied to growth performance. In conclusion, UTI in sows during pregnancy is a risk factor for arthritis and facial lesions in suckling piglets, as well as has negative effect on their growth performance.
