La endometritis bacteriana es una de las causas más comunes de falla reproductiva en yeguas, generalmente asociada a agentes bacterianos como Streptococcus equi, Echerichia coli, Enterococcus spp, Klebsiella sp., entre otros. De manera común se utilizan terapias antimicrobianas a base de fármacos betalactámicos y aminoglucósidos infiltrados a nivel uterino o en terapia sistémica. Para el presente estudio se tiene como objetivo principal evaluar la eficacia clínica de tres protocolos antibióticos en yeguas con diagnóstico de endometritis bacteriana y verificar su desempeño reproductivo postratamiento. La muestra se realizó con 90 yeguas diagnosticadas con infección uterina. Mediante examen clínico reproductivo, vaginoscopia y ecografía. Se tomaron muestras de cultivo uterino por medio de hisopado, a su vez se realizó antibiograma. Las yeguas fueron divididas en tres grupos de tratamiento antibiótico asignados según el resultado del antibiograma: penicilina G procaínica (n=4), ceftiofur (n=10) y gentamicina (n=20). Posteriormente se evaluó la eficacia clínica y el desempeño reproductivo de las yeguas. De las tratadas con penicilina, 75% (3/4) se recuperaron y dos quedaron gestantes; de las tratadas con gentamicina, 75% (15/20) se recuperaron y 8 quedaron gestantes; en tanto que de las tratadas con ceftiofur, 70% (7/10) se recuperaron y a 5 se le confirmó gestación. Se concluye no hubo diferencias clínicas o reproductivas postratamiento por efecto del tipo de antibiótico empleado.

The current study investigated the impact of chicken litter application on the abundance of multidrug-resistant Enterococcus spp. in agricultural soil. Soil samples were collected from five different strategic places on a sugarcane farm before and after manure application for four months. Chicken litter samples were also collected. Enterococci were enumerated using the Enterolert®/Quanti-Tray 2000® system and confirm and differentiated into species using real-time PCR. The antibiotic susceptibility profile of the isolates was determined using the disk diffusion method following the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines. The overall mean bacterial count was significantly higher (p < 0.05) in manure-amended soil (3.87 × 107 MPN/g) than unamended soil (2.89 × 107 MPN/g). Eight hundred and thirty-five enterococci (680 from soil and 155 from litter) were isolated, with E. casseliflavus being the most prevalent species (469; 56.2%) and E. gallinarum being the least (16; 1.2%). Approximately 56% of all the isolates were resistant to at least one antibiotic tested, with the highest resistance observed against tetracycline (33%) and the lowest against chloramphenicol (0.1%); 17% of E. faecium were resistant to quinupristin-dalfopristin. Additionally, 27.9% (130/466) of the isolates were multidrug-resistant, with litter-amended soil harbouring more multidrug-resistant (MDR) isolates (67.7%; 88/130) than unamended soil (10.0%; 13/130). All isolates were susceptible to tigecycline, linezolid and gentamicin. About 7% of the isolates had a multiple antimicrobial resistance index > 0.2, indicative of high antibiotic exposure. Although organic fertilizers are regarded as eco-friendly compared to chemical fertilizers for improving soil fertility, the application of untreated animal manure could promote the accumulation of antibiotics and their residues and antibiotic-resistant bacteria in the soil, creating an environmental reservoir of antimicrobial resistance, with potential human and environmental health risks.

This study was performed to investigate the distribution characteristics of airborne bacteria emitted from swine manure composting plants. The types of swine manure composting plants selected for the survey in this study were as follows: screw type, rotary type, and natural dry type. Mean levels of airborne bacteria in swine manure composting plants were 7428 (±1024) CFU m−3 for the screw type, 3246 (±1407) CFU m−3 for the rotary type, and 5232 (±1217) CFU m−3 for the natural dry type, respectively. Based on the results obtained from this study, the swine manure composting plant operated by screw type showed the highest concentration of airborne bacteria, followed by the natural dry type and rotary type. The monthly concentration of airborne bacteria was the highest in August and the lowest in November, regardless of the type of swine manure composting plant. The respirable size of airborne bacteria accounted for about 50% of the total. The ratio of respirable to the total quantity of airborne bacteria was 50%. The correlation relationships between airborne bacteria and environmental factors (temperature, relative humidity, particulate matters, and odor) were not found to be significant in the swine manure composting plants. The predominant genera of airborne bacteria identified were Micrococcus spp., Staphylococcus spp., Escherichia(E-coli) spp., Enterococcus spp., and Enterobacteriaceae spp.

Objective: To update readers on the significant changes in infectious diseases pharmacotherapy. Data Sources: An Index Medians and Iowa Drug Information Service search (1993–1994) of English-language literature pertaining to the selected topic areas was performed. Additional information from abstracts presented at scientific meetings were identified by the authors. Study Selection and Data Extraction: All identified studies were screened and those judged relevant to the update were evaluated. Data Synthesis: New or clinically significant data since 1992 that related to peptic ulcer disease, microbial resistance (e.g., Enterococcus spp., Streptococcus pneumoniae, Mycobacterium tuberculosis, Candida albicans), immunomodulators, and AIDS were evaluated and compared with previous data. Conclusions: There have been several exciting and significant changes in infectious diseases pharmacotherapy evident from this review.
