Apoorv Goel, Roli Bansal
Typhoid fever is caused by gram-negative organism Salmonella typhi. The usual presentation is high-grade fever, but complications like gastrointestinal (GI) hemorrhage and perforation are also seen frequently. With the advent of antibiotics, these complications are rarely seen now. We present a case of a young female who was admitted with a diagnosis of typhoid fever presented with a massive GI bleed from ulcers in the terminal ileum and was managed conservatively without endotherapy and surgery.

Interest in addressing antimicrobial resistance (AMR) has grown recently but little effort has been made to consider how existing and new vaccines could impact on AMR. A 2017 Chatham House meeting considered the role of vaccines and how to demonstrate their value through their impact on AMR. Ways existing vaccines have reduced antibiotic prescribing and the prevalence of some resistant organisms were reviewed. Other new vaccines could have a similar impact. In gonorrhoea, where complete resistance has developed, vaccine may be the best option...

BACKGROUND: Typhoid fever is an acute systemic infection of humans caused by Salmonella enterica subspecies enterica serovar Typhi (S. Typhi). In chronic carriers, the bacteria survive the harsh environment of the gallbladder by producing biofilm. The phenotype of S. Typhi biofilm cells is significantly different from the free-swimming planktonic cells, and studies have shown that they are associated with antibiotic resistance, immune system evasion, and bacterial persistence. However, the mechanism of this transition and the events leading to biofilm formation are unknown...

This is a case report of a 12-year-old returned traveler with typhoid and scrub typhus coinfection. The diagnosis of typhoid was made early with blood cultures and Widal Weil Felix serology. Persistent fever despite appropriate antibiotics for typhoid fever prompted a search for concomitant infection, which led to the diagnosis of scrub typhus confirmed by Orientia tsutsugamushi serology. The patient was given doxycycline with good clinical response. Scrub typhus infection should be an early consideration in the differential diagnoses of fever in a returned traveler from regions where it is endemic...

BACKGROUND: Salmonella has significant public health implications causing food borne and zoonotic diseases in humans. Treatment of infections due to Salmonella is becoming difficult due to emergence of drug resistant strains. There is therefore need to characterize the circulating non-typhoidal Salmonella (NTS) serovars in domestic animals and animal products in Kenya as well as determine their antibiotic resistance profiles. METHODS: A total of 740 fecal samples were collected from cows (n = 150), pigs (n = 182), chicken (n = 191) and chicken eggs (n = 217) from various markets and abattoirs in Nairobi...

Urinary tract infections (UTIs) caused by nontyphoidal Salmonella in a renal allograft recipient are a rare occurrence. Although there is some existing literature on Salmonella typhi bacteriuria and non-typhoidal bacteriuria, none of the cases has been reported in a renal transplant patient. This case report describes a rare instance in which group D Salmonella was isolated from a renal allograft recipient's urine culture and the patient was successfully treated with antibiotics.

INTRODUCTION: Typhoid fever is an endemic disease in India against which many antibiotics are available. In the recent times, emerging resistance to traditional antibiotics, such as Ampicillin, Chloramphenicol and Trimethoprim/sulfamethoxazole, Azithro-mycin and third generation Cephalosporins are being reported and increasingly being used in the treatment of invasive Salmonella infections. However, the latter two drugs have been reported with occasional clinical failures. Currently, we do not have data regarding their drug resistance levels in the recent isolates of Salmonella enterica subspecies enterica serotype Typhi...

Anna Colavecchio, Brigitte Cadieux, Amanda Lo, Lawrence D Goodridge
Foodborne illnesses continue to have an economic impact on global health care systems. There is a growing concern regarding the increasing frequency of antibiotic resistance in foodborne bacterial pathogens and how such resistance may affect treatment outcomes. In an effort to better understand how to reduce the spread of resistance, many research studies have been conducted regarding the methods by which antibiotic resistance genes are mobilized and spread between bacteria. Transduction by bacteriophages (phages) is one of many horizontal gene transfer mechanisms, and recent findings have shown phage-mediated transduction to be a significant contributor to dissemination of antibiotic resistance genes...
