Partial isolation and some properties of enterotoxin produced by Bacillus cereus strains

open access: yesMemorias do Instituto Oswaldo Cruz, 1993
Extracellular proteins produced by Bacillus cereus AL-42 and AL-15 were fractioned by chromatography on QAE-Sephadex and Sephadex G75. This last chromatographic process resulted in three peaks.

Prevalence of Colonization, Association With Disease Stage and Effect of Eradication of Staphylococcus aureus in Cutaneous T‐Cell Lymphoma: A Systematic Review and Meta‐Analysis

open access: yesJEADV Clinical Practice, Volume 5, Issue 3, Page 810-820, September 2026.
ABSTRACT Background Cutaneous T‐cell lymphoma (CTCL) is a rare and heterogeneous group of skin‐homing lymphomas with a largely unknown pathogenesis. Staphylococcus aureus (S. aureus) colonization has been implicated in exacerbating CTCL, particularly in advanced stages. Objectives This study assessed the prevalence of S.

Prevalence of Mastitis in Cows and Raw Milk Microbial Contamination in Selected Districts, Tanzania

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Cow milk produced in Tanzania suffers from poor quality due to bacterial contamination from mastitis udder predisposed by poor livestock husbandry and milk hygienic practices. The prevalence of mastitis was 75.6%, with a milk bacterial contamination rate of 78% and resistance to multiple antimicrobials. To safeguard the dairy industry and public health,

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

The Effect of Multi‐Strain Probiotics, Zinc and Copper on the Performance of Broiler Chickens Challenged With Clostridium perfringens

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Our study showed that challenging broiler chickens with Clostridium perfringens reduced performance and increased mortality. Conversely, supplementing the diet with additives, such as chelated zinc, chelated copper and probiotics, helped mitigate the negative effects of C. perfringens.
