Patent Claims:	1. A method of treating one or more bacterial infection in a subject, wherein the subject is immunocompromised, comprising administering to the subject in need thereof a combination of meropenem and vaborbactam. 2. The method of claim 1, wherein the bacterial infection is selected from the group consisting of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter cloacae species complex, Enterococcus faecium, Serratia marcescens, Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Chlamydia trachomatis, Mycoplasma pneumoniae, and Legionella pneumophila, Acinetobacter baumannii, Bartonella bacilliformis, Brucella species, Calymmatobacterium granulomatis, Campylobacter fetus, Francisella tularensis, Haemophilus ducreyi, Vibrio cholerae, and Yersinia pestis. 3. The method of claim 1, wherein the subject has a history of ongoing leukemia or lymphoma. 4. The method of claim 1, wherein the subject has had an organ transplant, stem cell transplant, bone marrow transplant, or splenectomy. 5. The method of claim 1, wherein the subject is receiving immunosuppressive medications. 6. The method of claim 1, wherein the subject is receiving bone marrow ablative chemotherapy. 7. The method of claim 1, wherein the subject has neutropenia. 8. The method of claim 1, wherein the subject is suffering from or has suffered from a malignancy. 9. A method of treating one or more bacterial infection in a subject, wherein the subject is suffering from or has suffered from a malignancy, comprising administering to the subject in need thereof a combination of meropenem and vaborbactam. 10. The method of claim 9, wherein the bacterial infection is selected from the group consisting of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter cloacae species complex, Enterococcus faecium, Serratia marcescens, Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Chlamydia trachomatis, Mycoplasma pneumoniae, and Legionella pneumophila, Acinetobacter baumannii, Bartonella bacilliformis, Brucella species, Calymmatobacterium granulomatis, Campylobacter fetus, Francisella tularensis, Haemophilus ducreyi, Vibrio cholerae, and Yersinia pestis. 11. The method of claim 8, wherein the malignancy is a hematological malignancy, and wherein the hematological malignancy is selected from the group consisting of acute lymphocytic leukemia, acute myeloid leukemia, AIDS-related lymphoma, primary CNS lymphoma, Burkitt lymphoma, chronic lymphocytic leukemia, chronic myelogenous leukemia, Hodgkin lymphoma, leukemia, multiple myeloma, myoproliferative neoplasms, and Sezary syndrome. 12. The method of claim 8, wherein the subject is suffering from or has suffered from a solid tumor, and wherein the solid tumor is a sarcoma or carcinoma. 13. The method of claim 1, wherein the subject has an absolute neutrophil count below about 1000 cells/mm.sup.3. 14. The method of claim 1, wherein the administration is oral, intravenous, intraperitoneal, intragastric, or intravascular administration. 15. The method of claim 1, wherein the dose of the meropenem administered is between 1 mg and 5000 mg and the dose of the vaborbactam administered is between 1 mg and 5000 mg. 16. The method of claim 15, wherein the dose of meropenem is 10 mg to 3000 mg and the dose of vaborbactam is 10 mg to 3000 mg. 17. The method of claim 15, wherein the dose of meropenem is 100 mg to 2000 mg and the dose of vaborbactam is 100 mg to 2000 mg. 18. The method of claim 1, wherein the meropenem and vaborbactam are administered in a weight ratio from 2:1 to 1:2. 19. The method of claim 1, wherein the meropenem and the vaborbactam are administered from one to four times daily, and wherein the meropenem and vaborbactam are administered from about 1 day to at least about 4 weeks. 20.
