Abstract
Intensive poultry farming faces challenges like gut inflammation in the absence of antibiotics, resulting in reduced productivity, heightened susceptibility to enteric diseases, and other complications. Alternative strategies are needed to manage inflammation and maintain sustainable poultry production. Yaks living in high-altitude hypoxic environments have specialized gut microbes. However, yak probiotics remain largely uncharacterized. We previously isolated a strain of Bacillus pumilus (named TS2) from yaks and demonstrated its potential as a probiotic in vitro. Therefore, in this study, we evaluated the in vivo growth-promoting, antioxidant, immune, and anti-inflammatory effects of Bacillus pumilus isolated from yaks in broilers. We demonstrated the safety of TS2 isolated from yaks in broilers. Furthermore, we found that TS2 increased the average daily weight gain (ADWG) and reduced the feed conversion ratio (FCR). Supplementation with TS2 also improved the mucosal morphology, the ratio of villi to crypt cells, and enzyme activity. High-throughput sequencing showed that the abundance of Lactobacillus was higher in the TS2 treated broilers. Importantly, the serum level of malondialdehyde (MDA) was reduced and the levels of total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) activity were increased in the low-dose TS2 group, while the inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were downregulated compared with the control group. We demonstrated that TS2 supplementation can increase the overall growth performance and ameliorate the blood parameters related to inflammation and immunity in broilers.

Microb Cell Fact 2023; 22:30. [PMID: 36803386 PMCID: PMC9936653 DOI: 10.1186/s12934-023-02027-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 01/21/2023] [Indexed: 02/19/2023] Open
Abstract
BACKGROUND Given the crucial role of gut microbiota in animal and human health, studies on modulating the intestinal microbiome for therapeutic purposes have grasped a significant attention, of which the role of fecal microbiota transplantation (FMT) has been emphasized. METHODS In the current study, we evaluated the effect of FMT on gut functions in Escherichia coli (E. coli) infection by using mice model. Moreover, we also investigated the subsequently dependent variables of infection, i.e., body weight, mortality, intestinal histopathology, and the expression changes in tight junction proteins (TJPs). RESULTS The FMT effectively decreased weight loss and mortality to a certain extent with the restoration of intestinal villi that resulted in high histological scores for jejunum tissue damage (p < 0.05). The effect of FMT on alleviating the reduction of intestinal TJPs was also proved by immunohistochemistry analysis and mRNA expression levels. Moreover, the abundance of health-threatening bacteria, belonging to phylum Proteobacteria, family Enterobacteriaceae and Tannerellaceae, genus Escherichia-Shigella, Sphingomonas, Collinsella, etc., were significantly increased, whereas beneficial bacteria, belonging to phylum Firmicutes, family Lactobacillaceae, genus Lactobacillus were decreased in the gut of infected mice. Furthermore, we sought to investigate the association of clinical symptoms with FMT treatment with modulation in gut microbiota. According to beta diversity, the microbial community of gut microbiota results reflected the similarities between non-infected and FMT groups. The improvement of the intestinal microbiota in FMT group was characterized by the significant high level of beneficial microorganisms with the synergistic decrease of Escherichia-Shigella, Acinetobacter, and other taxa. CONCLUSION The findings suggest a beneficial host-microbiome correlation following fecal microbiota transplanatation for controlling gut infections and pathogens-associated diseases.

Effects of Bacillus amyloliquefaciens TL106 Isolated from Tibetan Pigs on Probiotic Potential and Intestinal Microbes in Weaned Piglets. Microbiol Spectr 2022; 10:e0120521. [PMID: 35080439 PMCID: PMC8791190 DOI: 10.1128/spectrum.01205-21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Accepted: 12/16/2021] [Indexed: 11/20/2022] Open
Abstract
Bacillus amyloliquefaciens is a nonpathogenic microorganism whose highly active amylase is widely isolated from soil and plants. TL106 is an isolate of Bacillus amyloliquefaciens isolated from cold- and disease-resistant Tibetan pigs in Linzhi, Tibet. Here, we report that TL106 not only could survive in acidic environments, high bile salt concentrations, and high-temperature conditions but also was resistant to antibiotics. It significantly improved the growth performance of weaned piglets, especially in the prevention of diarrhea. The crude fiber and crude ash digestibility in weaned piglets after TL106 administration was considerably higher than that in other groups. The results of 16S rRNA sequencing conveyed that TL106 stabilized gut microbiota that was disturbed by the weaning process with an increased level of Lachnospiraceae, Peptococcaceae.rc4_4, Erysipelotrichaceae.L7A_E11, and Mollicutes.RF39. Hence, this study proved that Bacillus amyloliquefaciens TL106 might be a candidate for antibiotics in Duroc×Landrace×Yorkshire weaned piglets. IMPORTANCE Antibiotics are often used to promote animal growth and prevent diarrhea in weanling piglets. Nevertheless, intestinal pathogenic bacterial resistance and drug residues caused by antibiotic overuse are worthy of concern and demand an urgent solution. Bacillus amyloliquefaciens TL106 has been isolated from cold- and disease-resistant Tibetan pigs in Linzhi, Tibet. It significantly improved the growth performance, decreased diarrhea, increased the absorption of crude substances, and regulated the gut flora homeostasis in Duroc×Landrace×Yorkshire weaned piglets. As an antibiotic candidate, TL106 perfectly displayed its probiotic potential and pollution-free properties.

Abstract
The aim of this study was to evaluate the antibacterial potential of lactic acid bacteria (Weissella confuse, Pediococcus acidilactici, and Ligilactobacillus equi) isolated from healthy equine in Wuhan against Salmonella Typhimurium CVCC542-induced mice model on intestinal microflora. In previous studies, these isolated strains showed good probiotic potentials in vitro. In this study, fifty healthy mice were randomly divided into five groups, the blank control group, the control group, the Pediococcus acidilactici group (1 × 108 CFU/day), the Ligilactobacillus equi group (1 × 108 CFU/day), and the Weissella confuse group (1 × 108 CFU/day). The body weight in control group and Weissella confuse group showed significant decreased (P < 0.05, P < 0.01), while Pediococcus acidilactici group and Ligilactobacillus equi group showed good recovering after treatments. The lowest diarrhea rate was shown in Ligilactobacillus equi group after treatment. In histopathology, Ligilactobacillus equi group showed the least structural damage in duodenum, and all probiotic treatment groups showed less damage in cecum. The sequence data and optical transform unit showed that Pediococcus acidilactici group and Ligilactobacillus equi group had higher number than control group, while the diversity data showed that the control group and Weissella confuse group had lower diversity in cecum. Microbial community analysis showed increased abundance of Firmicutes, Bacteroidetes, uncultured_bacterium_f_Muribaculaceae, and Lactobacillus in treatment groups, while potential microbes that can induce intestinal diseases such as Verrucomicrobia, Akkermansia, and Lachnospiraceae_NK4A136_group decreased in the treatment groups. In conclusion, lactic acid bacteria isolated from the healthy horses could alleviate the infection of Salmonella and regulate intestinal flora.

Abstract
The aim of this study was to evaluate the antibacterial potential of Lactobacillus screened from Tibetan yaks on clinical symptoms and intestinal microflora in enteroinvasive Escherichia coli (EIEC) induced mice model. In vitro study, Lactobacillus reuteri (LR1) exhibited stronger resistance to acid and bile and inhibited the growth of EIEC than Lactobacillus mucosae (LM1). The mice were randomly divided into four groups i.e. the LR1 group (LR1 1 × 109 CFU/day), LM1 group (LM1 1 × 109 CFU/day), blank control group and control group. Mice in control, LR1, and LM1 groups were challenged with EIEC on day 23. The body weight in the control and LM1 groups were significantly decreased after the infection with EIEC (P < 0.05), whereas the body weight of mice in the LR1 group did not change significantly (P > 0.05). The lowest diarrhea rate was recorded in the LR1 group after infection with EIEC. The results showed that the number of pathogens in the control group was higher than that in the experimental groups. The sequence analysis and OTU classification showed that the duodenum, ileum, and cecum of mice in the LR1 group had the highest number of OTUs compared with other groups. Whereas, the diversity analysis showed that in duodenum, ileum and cecum of mice in the LR1 group had the highest abundance and diversity. The composition of intestinal microbes indicated the presence of high proportions of Firmicutes, Proteobacteria and Bacteroidetes. Heat map analysis indicated high abundance of Bdello vibrio in the duodenum of mice in the LR1 group, while many pathogens were found in the different part of intestines in the control group, such as Streptococcus, Clostridium and Pseudomonas. In conclusion, pre-supplementation of LR1 alleviate the clinical symptoms caused by E. coli, and promote a healthy gut flora.

Abstract
Yaks are an aboriginal breed of the Qinghai-Tibet plateau (3000 m), which are highly adaptable to cold and hypoxic environments. It is noticed that hypoxia and hypothermia can induce changes in intestinal microbial structure in animals. Increasing evidences suggested that probiotics supplementation can improve the balance of gut microbiota of animals. However, so far, very few studies have emphasized on the probiotics isolated from yaks in the Qinghai-Tibet Plateau. Therefore, a potential probiotic strain Bacillus velezensis was isolated from yaks. In the present study, a total of 18 Kunming mice (15-18 g) were equally distributed into two groups; control and probiotic treated groups (1 × 109 CFU/day). During the experimental period, all the mice from both groups were given standard normal diet ad libitum. At the end of the experiment, mice were euthanized and the intestines (duodenum, jejunum, ileum, and cecum) were removed for high-throughput sequencing. The results demonstrated that Bacillus velezensis supplementation showed beneficial effects on the gut microbiota of mice. Specifically, Bacillus velezensis supplementation increased the population of Lactobacillus and Ruminococcus in the duodenum, and Candidatus Arthromitus in the jejunum. Additionally, Acinetobacter in the duodenum and Helicobacter in the cecum were decreased after feeding Bacillus velezensis. Altogether, these findings suggested that Bacillus velezensis isolated from Tibetan yaks can improve gut microbiota of mice.

Abstract
Enteroinvasive Escherichia coli (EIEC) are well-known food-borne pathogens that cause animal intestinal diseases. Lactobacillus is believed to inhibit intestinal pathogens and maintain a healthy gut microbiota. This study aimed to investigate the effects of pre-supplementation of Lactobacillus from yaks (4500m) to prevent the clinical symptoms and the improvement of the disordered flora caused by E. coli infection. Forty healthy mice were randomized to four study groups (n = 10); Leuconostoc pseudomesenteroides (LP1), Lactobacillus johnsonii (LJ1), blank control, and control groups. Mice in the LP1, LJ1, and control groups were intraperitoneally challenged with EIEC O124 (1 × 109 CFU) on day 23. After two days, the mice in control group were recorded for high mortality. The diarrhea in LP1 and LJ1 groups was much lower than that in the control group, and no death was recorded. In histopathology, pre-supplementation of LJ1 and LP1 relieved the damage to the liver, spleen and duodenum caused by E. coli. In addition, the normal intestinal microecology was also affected by infection of EIEC, including an increase in relative abundance of Proteobacteria. At the same time, the beneficial bacteria were increased and harmful bacteria were decreased in different intestinal segments of the LJ1 and LP1 groups compared to the control group. In conclusion, pre-supplementation of LP1 and LJ1 can mitigate EIEC-induced intestinal flora dysbiosis and can also reduce EIEC-associated diarrhea.

Abstract
Despite being the most essential nutrient, water is commonly forgotten in the fields of pharmacy and nutrition. Hydration status is determined by water balance (the difference between water input and output). Hypohydration or negative water balance is affected by numerous factors, either internal (i.e., a lack of thirst sensation) or external (e.g., polypharmacy or chronic consumption of certain drugs). However, to date, research on the interaction between hydration status and drugs/excipients has been scarce. Drugs may trigger the appearance of hypohydration by means of the increase of water elimination through either diarrhea, urine or sweat; a decrease in thirst sensation or appetite; or the alteration of central thermoregulation. On the other hand, pharmaceutical excipients induce alterations in hydration status by decreasing the gastrointestinal transit time or increasing the gastrointestinal tract rate or intestinal permeability. In the present review, we evaluate studies that focus on the effects of drugs/excipients on hydration status. These studies support the aim of monitoring the hydration status in patients, mainly in those population segments with a higher risk, to avoid complications and associated pathologies, which are key axes in both pharmaceutical care and the field of nutrition.

Abstract
The purpose of this study was to evaluate the antibacterial activity and safety of bacterias with probiotic potential isolated from free-ranging Tibetan yaks in high altitude regions of Tibet. For this purpose, one Leuconostoc pseudomesenteroides strain (named P1) and two Lactobacillus johnsonii and Lactobacillus mucosae strains (named LY1 and LY2), respectively, were isolated from fecal samples of Tibetan yaks. The antibacterial activity of the isolates was studied using Escherichia coli (E. coli ATCC 25922), Staphylococcus aureus (S. aureus ATCC 26112), and Salmonella enteritidis (S. enteritidis NCTC 13349) as indicator pathogens. The results showed that LY1 had high antibacterial efficacy against E. coli and S. enteritidis, while P1 had the most powerful bacteriostatic ability against S. aureus. PCR amplification showed that all the isolated strains were positive for Ent P2 (enterocin P-like bacteriocin) and exhibited a high tolerance to bile and low pH. Moreover, the safety of P1, LY1, and LY2 was determined through antibiotic resistance experiments, resistance gene testing, and hemolytic analysis while the antibacterial activity was assessed by in vitro and in vivo experiments. The LY2 strain was abandoned as a potential probiotic due to the detection of the vanA gene. The mice were fed from days 1 to 30 in six groups, the P1-1 (gavaged with P1 1 × 108 CFU/day), P1-2 (gavaged with P1 1 × 109 CFU/day), LY1-1 (gavaged with LY1 1 × 108 CFU/day), LY1-2 (gavaged with LY1 1 × 109 CFU/day), control (gavaged with an equal volume of vehicle), and blank control (gavaged with an equal volume of vehicle) groups. After 30 days, mice in the P1-1, P1-2, LY1-1, LY1-2, and control groups were intraperitoneal challenged with 1 × 108 CFU of E. coli (n = 10) in the abdomen. After 2 days of infection, the mice in the control group showed more severe damage in the liver, spleen and intestine than the mice in the P1-2 and LY1-2 groups. The mice in the P1-2 and LY1-2 groups had lower rates of diarrhea and mortality than other groups. In conclusion, bacteria with probiotic potential isolated from yaks may possibly be effective and safe antibacterial substances, providing a new treatment method to reduce the incidence of diarrhea associated with bacterial diseases in yaks.

Antibacterial activity of Lactobacillus plantarum isolated from Tibetan yaks. Microb Pathog 2018; 115:293-298. [PMID: 29305183 DOI: 10.1016/j.micpath.2017.12.077] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 12/24/2017] [Accepted: 12/30/2017] [Indexed: 12/19/2022]
Abstract
The main purpose of our study was to isolate the Lactobacillus strains from Tibetan yaks, which may have antibacterial activity. Three Lactobacillus plantarum (L. plantarum) strains named LP1, LP2, LP3 and one Pediococcus pentosaceus (P. pentosaceus) named PT2 were isolated from fecal samples of Tibetan yaks. We regarded indigenous Escherichia coli (E. coli ATCC 25922) and Staphylococcus aureus (S. aureus ATCC 25923) as indicator pathogens. The Bacteriocins derived from these isolated strains manifested high antibacterial activity against E. coli, the highest activity was observed in the case of LP1. On the other hand, PT2 had the most powerful bacteriostatic ability against S. aureus. In addition, all strains were positive for Ent A, which plays an important role in secreting pediocin-like bacteriocins and shows potential probiotic traits of bile and low PH tolerance. Overall, L. plantarum strains in present study could be employed as effective antibacterial substances and can help to remit the problem of antibiotic resistance in veterinary medicine.

Abstract
OBJECTIVE Here, we evaluated the efficacy of probiotic interventions in prevention of antibiotic-associated diarrhoea (AAD) and Clostridium difficile diarrhoea (CDD) in older patients. METHODS PubMed, Embase, CENTRAL, CINAHL, and Web of Science were comprehensively searched from their dates of inception to May 2014. Only randomised controlled trials reporting data on probiotics including Lactobacillus, Bifidobacterium, Saccharomyces, Streptococcus, Enterococcus, and Bacillus-alone or in combination-versus placebo or absence of treatment in older patients (age ≥65 years) were included. Risk ratios (RRs) for AAD and CDD relative to placebo or absence of treatment were estimated. RESULTS Six trials with a total of 3562 patients were included. Only one trial showed that Bacillus licheniformis was effective for preventing AAD in older patients. However, there was no preventive effect for AAD and CDD with Lactobacillus acidophilus (Florajen), Lactobacillus casei Shirota, Saccharomyces cerevisiae (boulardii) lyo, mixture of Lactobacillus acidophilus and Bifidobacterium bifidum (Cultech strains), and mixture of Lactobacillus acidophilus CUL60, CUL21, Bifidobacterium bifidum CUL20 and B. lactis CUL34. CONCLUSIONS Our findings indicate that probiotics may not reduce the risk of AAD and CDD in older patients. However, with current published data, it is difficult to draw concrete conclusions. To confirm these findings, sample sizes, multi-centre, double-blind studies that consider factors such as probiotic strains and types of antibiotics are required.

Int J Infect Dis 2011; 15:e787-94.

Abstract
OBJECTIVES The aim of this study was to investigate the in vitro and in vivo anti-staphylococcal activity of a lactic acid bacterial strain and its effect on the intestinal histological damage caused by Staphylococcus aureus infection. METHODS Lactobacillus paracasei subsp. paracasei was isolated in our laboratory from breastfed newborn feces and identified phenotypically and genotypically. The strain was analyzed by spot-on-lawn and well diffusion assays for the production of bacteriocins against five antibiotic-resistant S. aureus strains isolated from the feces of hospitalized patients with antibiotic-associated diarrhea. The anti-staphylococcal activity of this strain was evaluated in fermented milk and in vivo using holoxenic rabbits. RESULTS The strain was able to produce a bacteriocin-like substance active against the staphylococcal strains. A reduction of 2 log in S. aureus cell numbers was registered in co-culture with L. paracasei in fermented milk. Administration of skimmed milk containing S. aureus (10(7) cells/ml) to healthy rabbits induced a persistent diarrheal state 5 days after the challenge. Dissection of the rabbits and consequent histological observations showed damage and an atrophy of the intestinal and colonic mucosae of the diarrheal rabbits; in contrast an arrest of the diarrhea concomitant with recovery of the intestinal villi and the colonic crypts was observed in the rabbits treated with L. paracasei-fermented milk. Furthermore, the diarrheal state persisted in spite of a decrease in the level of S. aureus cells in the feces of the rabbits receiving sterile milk; this was in contrast to the rabbits treated with L. paracasei-fermented milk, in which the decrease in the S. aureus fecal number was associated with the arrest of the diarrhea. CONCLUSIONS L. paracasei could act as a potential barrier to prevent S. aureus- associated injury and might exert its effect on the staphylococcal enterotoxins or their target.

Abstract
INTRODUCTION Antibiotic associated diarrhea (AAD) is a frequently encountered adverse event following antibiotic administration. Evidence suggests that probiotics may be beneficial in preventing and decreasing the severity of AAD. MATERIAL AND METHODS Adult patients who were prescribed antibiotics for 3-14 days were enrolled from eight Canadian centers. Study treatment was randomized at a 1 : 1 ratio of BIO-K+CL1285( (®) ) or placebo and was administered within 24 h of initiation to 5 days after termination of antibiotherapy. Patients were followed for 21 days after last dose of study treatment. The primary outcome was severity and incidence of AAD. Severity was measured by the total number of days with diarrhea and incidence was defined as the number of patients with at least one day with diarrhea over the total number of patients enrolled in the study. RESULTS 216 patients were randomized to BIO-K+ and 221 to placebo. The mean (SD) number of days with diarrhea was 1.19. (3.20) days for the placebo and 0.67 (2.05) days for BIO-K+CL1285( (®) ) (p = 0.040). Adjusted multivariate linear regression results showed that the duration of diarrhea for BIO-K+CL1285 (®)vs. placebo was reduced by 51.5% (b[SE] = 0.515 [0.256], p = 0.045). The incidence of diarrhea was 21.8% for the BIO-K+ and 29.4% for the placebo group (OR = 0.667, p = 0.067). Multivariate logistic regression, showed that the adjusted odds ratio of AAD in patients receiving BIO-K+ vs. placebo was 0.627 (p = 0.037). Study treatment was well tolerated. CONCLUSIONS BIO-K+ is effective for preventing and reducing the severity of AAD in patients receiving antibiotic therapy in a hospital setting.

Abstract
BACKGROUND Clostridium difficile colitis is the predominant hospital-acquired gastrointestinal infection in the United States and has emerged as an important nosocomial cause of morbidity and death. Although several institutional studies have examined the effects of C. difficile on hospitalized patients, its nationwide impact on surgical patients has yet to be defined. METHODS To provide a national estimate of the burden of C. difficile, we performed a five-year retrospective analysis of the Agency for Healthcare Research and Quality's National Inpatient Sample Database, which represents a stratified 20% sample of hospitals in the United States, from 1999 to 2003. All surgical inpatient discharge data from 997 hospitals in 37 states were analyzed to determine the association of C. difficile infections with patient demographics, hospital characteristics, surgical procedure, length of stay (LOS), total charges, and in-hospital mortality rate. Univariate analysis was performed to identify any association between the presence of C. difficile infection and the outcome variables using chi-square contingency table analysis or the Student t-test following the exclusion of patients with other medical complications. Multivariate regression analysis was used to determine whether the presence of C. difficile infection was an independent predictor of increased LOS, total charges, and in-hospital mortality rate when controlling for surgery type, age, sex, payor, and hospital characteristics. RESULTS Clostridium difficile infection was reported as a discharge diagnosis for 8,113 (0.52%) of all 1,553,597 inpatients who had undergone a general surgical procedure. The incidence increased significantly in 2002 (34% higher than in 2001; p < 0.0001). The following patient and hospital characteristics were associated with the highest incidence of C. difficile infection (all p < 0.0001): Age > 64 years (0.95%); Medicare beneficiary status (0.94%); north-eastern hospital location (0.73%); and large (0.55%), urban (0.56%), or teaching hospital (0.61%). Patients undergoing an emergency operation were at higher risk than those having operations performed electively (0.8% vs. 0.3%; p < 0.0001). Colectomy, small-bowel resection, and gastric resection were associated with the highest risk of C. difficile infection (incidence after colectomy 1.11%; odds ratio [OR] 2.77, 95% confidence interval [CI] 2.65, 2.89, p < 0.0001; small-bowel resection 1.17%, OR 2.40, 95% CI 2.26, 2.54, p < 0.0001; gastric resection 1.02%, OR 2.26, 95% CI 2.03, 2.52, p < 0.0001). Patients undergoing cholecystectomy and appendectomy had the lowest risk of C. difficile infection (cholecystectomy 0.41%, OR 0.37, 95% CI 0.35, 0.39, p < 0.0001; appendectomy 0.20%, OR 0.45, 95% CI 0.42, 0.49, p < 0.0001). Multivariable analysis demonstrated that C. difficile was an independent predictor of LOS, which increased by 16.0 days (95% CI 15.6, 16.4 days; p < 0.0001) in the presence of infection. Total charges increased by $77,483 (95% CI $75,174, $79,793; p < 0.0001), and there was a 3.4-fold increase in the mortality rate (95% CI 3.02, 3.77; p < 0.0001) compared with patients who did not acquire C. difficile. CONCLUSIONS Epidemiologic data suggest that the incidence of C. difficile infection is increasing in U.S. surgical patients and that the infection is most prevalent after emergency operations and among patients having intestinal tract resections. Infection with C. difficile is an independent predictor of increased LOS, total charges, and mortality rate after surgery and represents a considerable burden to both patients and hospitals. Preventing C. difficile infection offers a potentially significant improvement in patient outcomes, as well as a reduction in hospital costs and resource expenditures.
